El 9 de mayo de 2017 se presentó en Montevideo el libro Políticas del cuerpo, gobierno de la ciudad: el retorno a la democracia en Uruguay. El libro recoge resultados de una investigación realizada por Cecilia Seré Quintero (Udelar), bajo la orientación de Alexandre Fernández Vaz (UFCS). La investigación, realizada en el marco del Programa de Posgraduación en Educación de la Universidade Federal de Santa Catarina(Brasil), se inscribe en las interacciones académicas establecidas entre el Grupo Políticas Educativas y Políticas de Investigación (GPEPI) del ISEF-Udelar y el Núcleo de Estudos e Pesquisas Educação e Sociedade Contemporânea (UFSC). El marco general de la investigación tiene como objeto el análisis de cuestiones vinculadas al cuerpo en la política contemporánea. Más específicamente, la mirada está centrada en la ciudad de Montevideo, en la transición entre la dictadura cívico-militar (1973-1985) y el retorno a la democracia, alcanzando hasta el año 1990. Señalan los autores: "Se buscó establecer relaciones entre los modos de pensar y organizar el espacio público, y la configuración discursiva del cuerpo en términos políticos" (Seré Quintero y Fernandez Vaz, 2017, p. 19). De esta manera, en la investigación se observan las expresiones de la política en el espacio de la ciudad, espacio por excelencia de la política, específicamente aquellas expresiones que tienen al cuerpo como objeto: "El gobierno de la ciudad supone, en este sentido, una intervención sincrónica en el emplazamiento del cuerpo en el centro de la política moderna" (Seré Quintero y Fernandez Vaz, 2017, p. 12). Se trata de una intervención sobre la vida, una suerte de administración de los ritmos biológicos que se manifiestan en el individuo y la población en un territorio determinado. Los espacios privilegiados para esta intervención no se reducen al sistema educativo o la red hospitalaria; tal y como se destaca en el libro, parques públicos, plazas, playas, avenidas, calles, pasajes, etc. configuran toda una nervadura urbana en la que se puede observar las políticas del cuerpo. Con estos elementos sobre la mesa, cobra mayor relevancia el análisis de la modulación dictadura-democracia. Las fuentes de la investigación remiten fundamentalmente a documentos elaborados en la Comisión Nacional de Educación Física (CNEF) entre 1985 y 1990. Para la investigación desarrollada este organismo ocupa un lugar destacado en cuanto está direccionado a disponer y organizar los cuerpos en la ciudad. Además de los documentos elaborados por la CNEF, también se analizan otros de diferentes dependencias estatales: la Administración Nacional de Educación Pública (ANEP), la Intendencia Municipal de Montevideo (IMM) y diarios de sesiones del Parlamento. El libro se compone de un prólogo de los autores, una introducción, tres capítulos y consideraciones finales. El capítulo I se denomina "Cuerpo y ciudad: lo urbano en la política moderna". Está orientado a mostrar cómo, si se trata de lo urbano, el cuerpo es objeto de políticas. En este sentido, el tratamiento político del cuerpo tendrá que ver, en las ciudades, con la administración temporal y espacial, con el establecimiento de vías, rutas y ritmos de circulación, pero también con las formas de andar y de circular. Aparece ya en este primer capítulo una categoría fundamental: biopolítica. El cuerpo en la ciudad se piensa en la misma medida en que se piensa la maximización de la vida. Se destaca también en este capítulo la distinción entre vida pública y privada, así como el declive de dicha distinción en la modernidad, y la relevancia que tiene para las políticas del cuerpo. El capítulo II lleva como título "Política, tiempo libre y ciudad: gobierno del organismo en el retorno a la democracia". En este capítulo se entra de lleno en el análisis de las políticas públicas en el campo de la educación física, el deporte y la recreación, políticas establecidas por la CNEF. El trabajo con las fuentes, con referencias empíricas, en nada opaca la densidad teórica del análisis. Se podría decir, incluso, que en ocasión del material empírico analizado se desarrolla una discusión teórica excepcional para el campo de referencia, lo cual da pistas para comprender la posición epistemológica asumida en la investigación. El tercer capítulo se titula "Democratización de la Educación Física: del cuerpo a la conciencia". Allí se analizan las claves de las políticas de la CNEF, identificando dos vías discursivas complementarias: la inclusión y la conciencia. Se trataba de un discurso dirigido a toda la población, sin exclusiones, que apelaba a la participación voluntaria de las actividades propuestas a través de la creación de conciencia. Pero, una vez más, no se trata únicamente de la mera descripción de las políticas públicas sino de un riguroso análisis conceptual que en todo momento denota el esfuerzo por explicar la articulación de dichas políticas con lo que estaba sucediendo en el país a nivel social, cultural y político, en el que no se deja de retomar el análisis de las continuidades y rupturas entre democracia y dictadura. De esta manera, la investigación echa por tierra de un modo incontestable la muchas veces pretendida asepsia ideológica de la educación física, el deporte y la recreación. En las consideraciones finales se hace bastante más que un balance de la investigación. Es un pasaje de alta densidad conceptual en el que se retoman los principales elementos presentados en los tres capítulos centrales, pero también se abren nuevas perspectivas de análisis e investigación. Es destacable, además, que las consideraciones finales son utilizadas para presentar discusiones sobre algunas de las categorías utilizadas. Por ejemplo, respecto de la expresión "política del cuerpo", se trae una vez más a la palestra, como varias veces a lo largo del libro, a Hannah Arendt y Michel Foucault, pero también a Jean-Claude Milner y Alain Badiou, entre otros. La discusión presentada allí, aunque no se pueda decir que es independiente de la investigación realizada, tiene su valor en sí misma. Se destaca en la investigación el uso sistemático de algunos conceptos, por ejemplo: políticas del cuerpo, biopolítica, u otros tal vez menos evidentes, como las diferencias que se pueden establecer entre organismo y cuerpo o las relaciones entre los conceptos de política y vida. Se trata de conceptos más o menos recientes, no solo para el campo de la educación física, sino para las humanidades y las ciencias sociales en general, que aquí se ponen en movimiento de manera rigurosa. De ese modo, la investigación ayuda a entender, a avanzar en la posibilidad de decir que, así como toda educación es educación del cuerpo, toda política toca en la cuestión del cuerpo. Contribuye a releer el concepto de política especialmente en la modernidad, sobre todo si se tiene en cuenta que habitualmente pensamos la política como algo que pertenece exclusivamente al terreno de las ideas y ubicamos allí las ideologías, la cuestión del poder, etc., pasando por alto que toda política es política del cuerpo; en ese escamoteo dejamos escapar lo esencial. La investigación que se nos presenta en este libro permitiría arriesgar una hipótesis: la cuestión política fundamental de la modernidad no se conforma por las ideas, las ideologías o el poder; la cuestión política fundamental es la del cuerpo, porque a lo que se enfrenta la modernidad es al problema de la multiplicidad de lo viviente y descubre, con Maquiavelo, con la multiplicidad hablante de los seres hablantes, lo que después se va a poner de manifiesto de diferentes maneras, por ejemplo, en Spinoza, Hobbes y Rousseau. Otra de las contribuciones relevantes de la investigación está en el tratamiento del pasado reciente. En Uruguay se ha visto cómo es difícil tratar este asunto, no solamente por cuestiones teórico-metodológicas sino porque se involucran polémicas diversas. En este sentido, la investigación de Seré Quintero contribuye a darle objetividad al tema, desde el punto de vista conceptual y empírico, a un problema que no se agota en lo ideológico; diría más: contribuye a objetivar un problema que es difícil de captar en el terreno de la ideología o, incluso, que lo ideológico oscurece. En la última parte de esta reseña voy a referirme a algunos elementos puntuales del libro. En el análisis de la transición de la dictadura cívico-militar a la democracia hay un elemento que me parece fundamental: la reubicación de la educación del cuerpo en función del giro ideológico que supuso el retorno a la democracia, el mentado "cambio en paz" de cara a la "pacificación de la sociedad" por la vía de la superación del pasado, hacia un futuro en el que se disolverían las divergencias en el terreno de las posiciones políticas. En el giro que suponía el cambio en paz, tal y como se muestra en el libro, el enemigo ya no es el otro político, el extranjero, sino la pobreza: se trata de un enemigo interno. De esta manera, con la educación del cuerpo, dentro de lo cual se ubica a la educación física, pasamos de corregir el cuerpo, de disciplinarlo, castigarlo, torturarlo, a retomar por una vía renovada lo que ya estaba presente en el discurso pedagógico vareliano: en la recuperación de la democracia, se propone que la pobreza va de la mano de la ignorancia. Tras la afectación del autoritarismo, un rasgo que nunca dejó de estar en el horizonte de la educación física habida cuenta de la vertiente militar que se encuentra en su historia, se hacía necesario otro giro: de la imposición de las actividades a la conquista de las voluntades, del disciplinamiento puro y duro a la generación de conciencia. La investigación muestra que durante la primera gestión de la CNEF posdictadura, la inclusión y el convencimiento fueron dos ejes fundamentales; se trataba de acciones dirigidas a "crear conciencia", con actividades "accesibles a todos los ciudadanos", para que se practique el deporte "como opción voluntaria y convencida" (Seré Quintero y Fernandez Vaz, 2017, p. 80). En este sentido se observa una especie de "dulcificación" de la educación física; se trataba de amenizarla, de manera que estuviera en concordancia con una forma amigable de hacer política (Seré Quintero y Fernandez Vaz, 2017, p. 55). Entraba allí con toda su fuerza la educación para el tiempo libre, esta vez en el escenario de los nuevos "enemigos" (o no tan nuevos, ya que hay antecedentes por lo menos en los argumentos para la creación de las Plazas Vecinales de Cultura Física a principios del siglo XX): se trataba de promover un uso adecuado del tiempo libre, un uso que alejara "a la juventud de los flagelos de la drogadicción, del alcoholismo y promoviendo mejores estilos de vida, para una existencia más provechosa, más feliz y solidaria" (palabras de Julio César Maglione en 1989, en ocasión de un balance de su gestión como Director de la CNEF; citado por Seré Quintero y Fernandez Vaz, 2017, p. 59). En estas breves referencias se podrá observar que no es extraño suponer algo así como una ideología de la desideologización. La investigación muestra el giro discursivo entre dictadura y democracia; mientras que en dictadura el discurso de la CNEF era claramente propaganda política nacionalista que ensalzaba al propio régimen, en los primeros años de democracia se pretendía estar "al margen de concepciones políticas" (Seré Quintero y Fernandez Vaz, 2017, p. 73). De esta manera, aunque suene paradójico, la investigación proporciona elementos para el debate ideológico, imprescindibles para toda discusión política. Como se ha visto, entonces, la investigación presentada en este libro es una contribución de altísimo valor para el campo de la educación física, pero no solo para él. En su lectura, se verá cómo la cuestión del cuerpo, y especialmente la de la educación del cuerpo, no es un tema menor ni coyuntural, tampoco marginal; es más bien un aspecto central de toda sociedad y cultura. Por esta razón, el material que ahora tenemos a disposición gracias a la política de publicaciones de la Comisión Sectorial de Investigación Científica (CSIC-Udelar) contribuye a la comprensión de los hechos en un período determinado de nuestra historia reciente, pero también a la comprensión de la potencia y el alcance de los conceptos que se ponen en juego.

Unlike much of the secondary literature on Shakespeare, "Immanent Shakespeares: Politics, Performance, and Pedagogy" labors less to determine what Shakespearean texts might mean than to explore the cultural work these texts do while working in conjunction with contemporary institutions of learning and technologies of performance. Shakespeare studies too often takes the determination (or destabilization) of meaning as its telos, even when it's largely informed by performance criticism. This project sets meaning aside to focus on how Shakespeare's textuality gets mobilized through performance in order to produce material effects--effects that exceed and shape semantic meaning. Semantic and hermeneutic vocabularies leave performance scholars very few terms with which they might interrogate performance's most salient features: duration, embodiment, light, discipline or affect. Making and coming to terms with what Shakespeare can do inevitably involves refiguring the relationship between Shakespeare's text and performance practices. In the dissertation, I argue that the field of Shakespeare studies too often figures the difference between textuality and performance spatially . These spatial models figure performance in prepositional relation to textuality: performances arise from the text or are interpretations of textuality. Performance has largely been understood as an interpretation of a Shakespearean meaning residing within a static (albeit polysemic) textuality. On stage or on screen, performance is continually represented as exterior to--and is considered over-determined by--textuality. My project, instead, figures the difference between stage/screen and page in terms of time. This move, from figures of space to figures of time, forces a reconsideration of many disciplinary assumptions (in literary, film and performance studies). Cultural studies' spatializing tendency, inseparable from the way it often figures difference (as "difference between" two discrete identities), is rooted in a long history of transcendental dialectics. Textuality and performance are framed, spatially, in terms of transcendence (even when stage-centered criticism tries to invert this relation, prioritizing performance, it nevertheless continues to understand difference within a transcendental relation). My project moves from a transcendental, spatial understanding of difference to one rooted in immanent, temporal duration. Giorgio Agamben recently identified "two different trajectories in contemporary French philosophy, both of which pass through Heidegger: a trajectory of transcendence , which includes Levinas and Derrida and goes back through Hussurl to Kant; and a trajectory of immanence , which includes Foucault and Deleuze, and goes back through Nietzsche to Spinoza." The dissertation works throughout to illustrate how this shift--from transcendental, spatial constraint to immanent, temporal production--allows for more nuanced discussions of elements constitutive of performance. The project considers Shakespearean performance within a variety of institutional arenas; different chapters consider reading practices, teaching practices, student performance, theatrical enactment, and new (and old) media engagement. This approach entails a series of interlocking, close, rhetorical readings of particular performances, theatrical/filmic/video/digital media technologies, arts/educational legislation, as well as the institutional discourses accompanying each. These close readings work to refigure the problem of textuality and performance in civic, aesthetic and pedagogical discourses; each chapter, subsequent to this refiguration, ends by proposing innovative, practice-based solutions. In Chapter One, I build on the critique of spatialized understandings of text and performance outlined in the introduction in order to argue that the humanities' figuration of difference and power (alongside attendant assumptions about the relationship between self and structure) continues to hide more than it reveals about culture, history, power and performance. In the chapter, I argue for and illustrate what an alternative, immanent critique might look like. The chapter focuses on two "objects" (a methodological term which seems to point to how performance is always already spatialized): 1) a "radical" or "transgressive" performance of Macbush , a contemporary re-imagining of Macbeth , and 2) a seemingly co-opted, official, "normative" performance of Macbeth sponsored by Boeing, the "right-wing" NEA, and the US Department of Defense. The chapter examines these two ostensibly opposed productions by rehearsing a dialectical or "transcendental" critique and using a common (hackneyed) reading of de Certeau's strategy/tactic distinction--one which emphasizes and prioritizes de Certeau's interest in space. I then complicate this reading by showing how de Certeau's figuration of power and performance within the panoptic city already includes an inclination towards an immanent understanding of power's circulation--one that emphasizes time and complicates the spatial cartographies upon which dialectical movement finds its ground and proper "identity." Through this immanent reading, I argue that dialectical understandings of culture and power rely upon a particular way of understanding the priority of space, one strengthened by Cold War discourses of cultural fronts and quantitative, incursive movements through homogenous space (both Macbeth and Bush, in prioritizing the stability of space over the contingencies of time, make this same tragic flaw in different ways). Ultimately, I argue that an immanent understanding of culture and power corresponds with contemporary changes in the shape of Empire and new ways of conceptualizing the flows of global capital, ways rooted in performance's duration and affect. Further, this immanent reading (and the shape of Empire and history correlative to this approach) highlights the dangers of the Left's reliance upon historical analogies that flatten important differences between Vietnam and Iraq or between Bush and Macbeth. Chapter Two develops the notion of immanent critique by revisiting dualistic notions of self and structure in film theory and performance studies. In this chapter, I look at the spatial arrangement of spectators, specific media, and apparatuses of projection. Through a reading of Prospero's Books , a 1991 "new media" film using proto-HDTV technologies and bourgeoning CGI graphics software, this chapter looks at film's ability, through these technologies, to trouble film theory's traditionally spatial understanding of filmic semiotics and the spectator's relation to the (transcendent) filmic apparatus. This chapter introduces an immanent performance theory to film theory by offering a new reading of the latter's key texts--from Munsterberg and Armheim, to Balazs and Metz, to Benjamin's Artwork essay--highlighting along the way each theorist's relation to the "immanent turn" in cultural studies. Key here will be the role each theorist gives to temporal relations. Particularly useful in rethinking the spectator's relationship to the (new or old media) apparatus is Benjamin's notion of "creative innervation"--a term he uses to show how the spectator's body is productively enlivened, rather than negatively determined, by a technological apparatus which becomes, for him or her, a prosthesis. This chapter puts Benjamin into contact with Deleuze to sketch out what an immanent model of reception might entail once traditional notions of the filmic apparatus' (over-) determinism have collapsed. This immanent understanding of filmic reception--a productive reception modeled in Prospero's Books --builds upon various notions of "pseudopresences" and theories of "affective faciality/physiognomy" sketched out by twentieth century film theorists in order to rethink the presence/absence binary and the various ways in which this binary gets unevenly mapped onto the disciplines of theatre and film. Chapter Three looks at how changing technologies continue to reconstitute the disciplinary gulf between film and theatre. In this chapter, I look at two interlocking performances: Richard Burton's 1964 Electronovision Hamlet and the Wooster Group's "new media" Hamlet . Working with Deleuze's idea of "the theatre of repetition," and continuing to work with Walter Benjamin's notion of "creative innervation," this chapter examines the technologies of repetition each Hamlet employs in order to read, write, and perform with the pre-recorded yet affective and "pseudopresent" specters of history. In July of 1964, three performances of the Burton-Gielgud Hamlet were recorded and edited together thanks to "miracle of Electronovision." The resulting "Theatrofilm" was then screened for two days in over one thousand theaters in order to give audiences the "liveness" of a Broadway show right in their own local theater. Recently, the Wooster Group has been staging another version of Hamlet , one that utilizes the Isadora and Final Cut Pro platforms to digitally remix and reframe the Burton-Gielgud production as an historical background upon which the company acts. Onstage, The Wooster Group imitates the 1964 Hamlet gesture for gesture in what the group likens to an archeological reconstruction, but I argue for an alternate figuration, one that is less spatial and more temporal in its figuration of history. This chapter uses these two performances (and their contemporary technologies) to ask how the so-called "new" media differently mediate our relationship with the past. I argue that new technological interfaces enable us to engage in historiographical research on stages and screens in ways that are singularly durational and within registers that are incommensurate to the textual historiographies of journals and monographs. Each of the Hamlet productions I treat figures a relation to history, treating the past as an interactive ensemble of images that are engageable yet immutably scripted. Chapter Four begins my engagement with critical pedagogy as I attempt to rework Freirean accounts of the classroom as a space of cultural contradiction and potential "liberation." The chapter asks how we might instead see classroom practices as productive of political, economic and ethical behaviors. Since the 1980s, critical pedagogy has rallied for the inclusion of "hip hop in the classroom" as part of a culturally relevant, Freirean model of connecting language with the lived experience of inner-city youth. But the movement begins to achieve success at the very moment hip hop begins losing its geographic specificity. Recently, a number of programs ("Shakespeare is Hip Hop," "Shakespeare: the Remix," and "Shakespeare in Urban Slang") have sought to connect Shakespeare and hip hop as a way of bridging the divide between the spaces of high and low culture. In this chapter, I examine the strange effects of local, culturally specific pedagogical practices fusing Shakespeare and hip hop which--like the music itself--have been removed, practiced and copied outside of what was once their "proper" space. What happens when suburban youth are asked by their teachers to perform Macbeth in hip hop vernacular? YouTube abounds with blackface Shakespeare. More importantly, though, the chapter rethinks intercultural borrowing and how the logic of "appropriation" falsely frames culture as private property at the same time that young people who identify with remix culture increasingly strive for a "creative commons" and continually challenge the spatial proprieties of culture. This chapter puts the "culture wars" into dialogue with the "copyright wars" and argues that, in a world where the line between public and private properties and spaces is increasingly blurred by virtual glocalities, digital rights management software and copyleft legal theories, cultural studies needs to rethink the spatial logic of cultural appropriation. Chapter Five brings immanent critique to the space of the classroom by examining another the Shakespeare teaching docudrama. These films, both fictional and documentary, chronicle "successful" pedagogues and the at-risk students whose lives they transform. In this chapter, I look at a few of these films alongside the No Child Left Behind Act's legislation on "character education." Performing a genealogy of the "character education movement" from the Greeks to 21st century US contexts, this chapter looks at the way in which Shakespearean repetitions operate to construct both a particularly American Shakespeare as well as a particularly American characterization of the student body. Centering on Prince Hal's Saint Crispin's Day speech, this chapter also explores the way in which discourses of national "character" and their corresponding pedagogies rely upon a particularly vertical (patrilineal, spatial, transcendental) notion of repetition and differentiation, one which might be refigured by Hardt and Negri's notion of how the immanent multitude operates in time. This chapter moves from the performance of character to a notion of "performing character." Much as earlier chapters refigured text/performance or apparatus/performance oppositions, this chapter shows how dialectical pedagogies might give way to durational, embodied performance pedagogies. The dissertation's concluding chapter, its post-script, uses the pedants of Love's Labour's Lost to engage in an interdisciplinary genealogy of the geek. I focus on three figures of the student body's relation to technology (the bookworm, the computer nerd, and the drama queen) in order to better understand how the "geek" has gained increased importance as a category of social difference and exclusion. The conclusion asks: How does the alterity of the geek historically produce and trouble the mutual exclusivity of love and labor , humans and machines, males and females, the curricular and the extracurricular, and/or the physical and the metaphysical? As a means of overcoming learning's alienation from the social, the dissertation concludes by introducing a "geek chic" performance pedagogy. This pedagogy uses training in digital video editing to include the social, and often virtual, extracurricular lives of students. Through editing their own performances (as they often already do within the world of social networking sites), students will rehearse the behaviors, gestures, expressions and temporal movements that constitute what we perceive as character. By examining these "character effects," students are trained to understand character differently--less as an originary space or cause of performance and more as a legible effect of performative behavior.

These images were produced using 230 GHz observations performed in 2017 April. Additional observations are required to investigate the persistence of the primary image feature- A ring with azimuthal brightness asymmetry- A nd to quantify the image variability on event horizon scales. To address this need, we analyze M87* data collected with prototype EHT arrays in 2009, 2011, 2012, and 2013. While these observations do not contain enough information to produce images, they are sufficient to constrain simple geometric models. We develop a modeling approach based on the framework utilized for the 2017 EHT data analysis and validate our procedures using synthetic data. Applying the same approach to the observational data sets, we find the M87* morphology in 2009-2017 to be consistent with a persistent asymmetric ring of ∼40 μas diameter. The position angle of the peak intensity varies in time. In particular, we find a significant difference between the position angle measured in 2013 and 2017. These variations are in broad agreement with predictions of a subset of general relativistic magnetohydrodynamic simulations. We show that quantifying the variability across multiple observational epochs has the potential to constrain the physical properties of the source, such as the accretion state or the black hole spin. © 2020 The Author(s).

 Jeremy Gilbert and I sometimes joke about TOP, the Transindividual Oriented Philosophy. The reference is obviously to the phenomenon of OOO (Object Oriented Ontology) in the early part of the millennium. As much as our joke has to do with sort of doctrinaire and polemical way the former arrived on the scene and our lack of interest in any such thing. (I should say in a parenthetical that is way too late, one of the things that always troubled me about OOO is that it emerged and thrived on blogs, but blogs with their intersection of the social and the technological seemed the last thing that the last thing that the crowd wanted to think about. Part of what makes me irredeemably a historical materialist is that I think the question of understanding where one is thinking from is paramount even if a bit quixotic--one can never see the ground that one speaks from). Despite this joke transindividuality, at least in terms of contemporary writers who use the concept, less a school of thought than a series of intersecting critiques and articulations. Or, if one wanted to be clever about it, the collection of writers who work on transindividuality are all part of a general orientation that is individuated differently in each of their specif philosophical articulations. I would say more about this but I feel like this is something that I tried to say with the examination of Balibar, Stiegler, and Virno in The Politics of Transindividuality.In that book I did not really discuss Bernard Aspe or Vittorio Morfino (at least at any length). However in the past month of so I have been reading a book by each of them that makes it clear how much they are part of the same metastable unity of philosophers. The books in question are Morfino's recently published Intersoggettività o Transindividualità: Materiali per un'alternativa  (a book I was able to work through in Italian thanks to the generous help of Dave Messing who let me look at an early draft of the English translation) and Bernard Aspe's Les Fibres du Temps  published in 2018. The two books are connected not just through their shared engagement with transindividuality, but in their use of the concept to overcome existing, perhaps even dominant, conceptions of individuality, subjectivity, and intersubjectivity. However, both books do so in very distinct and different ways, with different methods and genealogies. Morfino book, like all of Morfino's work, is absolutely admirable in its scholarship and erudition. Or, more to the point, Morfino's talent is an ability to combine a radical provocation with scholarly erudition. Morfino has a remarkable ability for going deep into the philological connections of a text or problem, working out all of the intersections and implications. However these investigations never seem like purely scholarly pursuits; the tasks and problems of radical politics are always close to hand.  The history of philosophy is examined for the ways in which it has led us to our particular historical moment, and what might be done if we thought and acted differently. As the title suggests Morfino's book on intersubjectivity or transindividuality deals with an opposition between two different ways of understanding social relations. However, this opposition is not a matter of simply picking a side. As Morfino argues, even as intersubjectivity has been the dominant way of conceiving of social relations it still has for the most part been an afterthought in a philosophical tradition that has started from the individual subject. The way that the individual subject has been figured, in terms of its interiority and subjectivity, has made it difficult to grasp its relations with others, or reduces it to the general problem of how the external world can be known. As Morfino points out, Descartes the philosopher who gave us the cogito, who claimed that he could know himself prior to knowing the world, is the same philosopher who wondered if the figures under hats and coats he saw out the window might be automatic machines. As Morfino reminds us Descartes can only resolve this problem through the same way that he resolves the problem of knowledge in general; how we know other people is no different than how we know the objects in the world. The development of interiority, which begins with Descartes, has as its corollary the creation of intersubjectivity as a perpetual problem. The subject's assertion of its own certainty posits other people and with them social relations as a perpetual afterthought. Morfino charts the emergence of the dominant history of interiority and intersubjectivity from Descartes through Leibniz and Hegel, while at the same time charting its alternative, transindividuality emerging through Spinoza, Marx, and Freud, to be developed further in Althusser, Goldmann, and Pêcheux. The first trajectory passes through the concepts of cogito, monad, and subject, creating a concept of identity, interiority, and teleology, while the second trajectory, that of transindividuality has a largely subterranean dimmension. Morfino's orientation with respect to all of these problems can be considered primarily Althusserian, not just because he is influenced by Althusser but because he takes on an Althusserian labor of reading. Just as Althusser saw his task as one of reading the Marxist philosophy between the lines of Marx's critique of political economy and the political interventions of Marx, Lenin, and Mao, producing the concepts of overdetermination and structural causality, Morfino is able to excavate the concept or idea of transindividuality prior to its letter by consider the problem of relation in the history of philosophy.One of the more interesting interventions along these lines is his reading of the concept of Weschelwirking (interaction) in Marx and Engels. This concept is developed by Engels in his Anti-Dühring to complicate any linear or mechanical relation of cause and effect:....cause and effect are conceptions which only hold good in their application to individual cases; but as soon as we consider the individual cases in their general connection with the universe as a whole, they run into each other, and they become confounded when we contemplate that universal action and reaction [Weschelwirkung] in which causes and effects are eternally changing places, so that what is effect here and now will be cause there and then, and vice versa.This understanding of the mutual intersection and interaction of effects and causes informs an understanding of the mode of production that is something other than the classical and mechanical action of a base on a superstructure. As Morfino cites a passage, which also appears in Althusser's "Contradiction and Overdetermination"The economic situation is the basis, but the various elements of the superstructure — political forms of the class struggle and its results, to wit: constitutions established by the victorious class after a successful battle, etc., juridical forms, and even the reflexes of all these actual struggles in the brains of the participants, political, juristic, philosophical theories, religious views and their further development into systems of dogmas — also exercise their influence upon the course of the historical struggles and in many cases preponderate in determining their form. There is an interaction [Weschelwirkung]  of all these elements in which, amid all the endless host of accidents (that is, of things and events whose inner interconnection is so remote or so impossible of proof that we can regard it as non-existent, as negligible), the economic movement finally asserts itself as necessary. Otherwise the application of the theory to any period of history would be easier than the solution of a simple equation of the first degree.As Morfino argues this concept of interaction is not often named as such by Marx, but in some sense it is at work in other names, or other concepts such as the interaction of production, distribution, and consumption that opens the 1857 introduction. Morfino's excavation of the concept culminates in his reading of Althusser's own articulation of the concept of transindividuality without the name. In Reading Capital Althusser posits that just as forces of production cannot be reduced to technology, relations of production cannot be reduced to intersubjectivity. As Althusser writes,"While the productive forces cannot be reduced to machines or quantifiable techniques, the relations of production cannot be reduced to relations between men alone, to human relations or intersubjectivity, as they are in the historicist ideology." Beyond this assertion Morfino traces as thought of transindividuality in the disagreement of Althusser and Lucien Goldmann. Goldmann did use the term transindividuality, but, as Morfino argues Goldmann in thinking the transindividual as the "relations of production" reduces it to a collective subject, to society as a subject, returning the concept to the subject and interiority it was meant to escape. Transindividual is not the genesis of the collective, but the interrelation, or interaction, of the constitution of the collective and the individual. As such, and this is the importance of the discussion of the concept of interaction in Engels and Marx, it is as much a rethinking of causality and of relations as it is a rethinking of subjectivity and individuality. Aspe's book is punctuated by discussion of films including ArrivalBut honestly this is here because I needed to break up the postBernard Aspe begins with the similar problem as Morfino's book, the priority of interiority over relation. For Aspe, however, this problem has less to do with a historical excavation than an assumed starting point. The orienting figures of our thought are that of an interiority accessible only to us, and the interiority of the other, unknown to us and only accessible indirectly. Any connection, any relation other than a kind of analogy, in which I know the other by comparing them to myself is excluded. It is precisely this excluded space that Aspe sets himself to explore, an examination of the space of subjectivation, "such a space is constituted by a play of interiorities and of relative exteriority, which do not correspond to the play of opposition between the interiority of the individual and the exteriority of the world of the other." Aspe's formulation of subjectivation is explicitly drawn from Simondon. (of the two books under consideration his book is more Simondonian in its concept of transindividuality while Morfino's is more Althusser/Balibarian). For Simondon the subject has to be thought as the relation between the individual and its preindividual relations that constitute the common. As Aspe puts it, "a collective is constituted by the laws that put in common the potentials carried by each, and thus, by the formation of new system..given its own proper energy." Or, to put it more directly "the group is capable of acting in the world because they already act on each other." The common space of our collective and individual individuation is time. Time, or a particular relation of temporality is both the constitution of individual and collectivity. This demands a discussion of the way in which time, temporality is both the site of our individuation, our specific memories, and our shared belonging.  This is true even if we do not remember what constitutes our identity and cannot situate our place ourselves in what constitutes our commonality. As Aspe writes, "The fiber of time, it is the relation between an irreparable loss and a unlocalizable persistence. Common memory, itself without support, comes in the places of this absent space, where it inscribes memory."Aspe investigates common time by two different trajectories, first through a consideration of film. His book is punctuated by a series of inserts dedicated to films from Gaslight to Arrival. As he argues film gives us direct access to the common memory. Film is in some sense the object of a common memory, becoming part of shared references, it is also in some sense, for a limited time, a temporal object, in which the viewers experience the same images, ideas, and associations. Of course all of this is forgotten when people leave the theater (or shut their laptops), despite this loss film often documents the unlocalizable persistence of a historical moment. As Aspe writes, "The "new" American cinema (Aronofsky, Nolan, Anderson, but also for the intermediate generation, Cameron…) is not always convincing, but this is no doubt due to the bias that makes it special, according to which it is only by relying on déjà vu that we can produce new images. The situations that cinema takes for its point of view are willingly "archetypical."The archetypes can be found through a return to an American mythology (the heroic entrepreneur and radical individual of Anderson's There Will Be Blood), to the unconscious (the double as product of relation and the devouring other in Black Swan, another film of Aronofsky), to popular imaginary (super heroes)."Aside from the odd appellation of "new" American cinema, it  is unclear if this diagnosis is as much about the individual aesthetics of the different directors than it is about a general trajectory in the production and marketing of film in which the past is seen as a reservoir of images to be mined for new films. One might say, following this remark, that the current stage of production in the age of intellectual property in which even the most forgettable movies, shows, and comic books from from the past are remade, (Watchmen, Night Court, Morbius), might not be some horrible deviation from our historical moment, but its most accurate reflection. We are living in a remake in which the conflicts of the past generations are relived and nostalgia for the immediate past has replaced hope for the future. Which brings us to the second consideration of common time, that of capital as the standardization of time. Aspe goes over the arguments of E.P. Thompson and Foucault on the standardization of time, adding to this discussion the point that all conflicts over labor take place within the standardization of time. Aside from Simondon, Aspe draws from an eclectic group of thinkers, Wittgenstein, Foucault, Kierkegaard, but perhaps the most surprising is Mario Tronti who often figures in such formulations as this, in which the antagonism, the opposition, between worker and capital is understood to be central, and accepting standardized time as the terrain of conflict, fighting over more work or less, is to fight on the terrain of capital. Capital can be understood as a standardization of time, space, and culture, in order to constantly expand. However, Aspe also draws from ecological thinkers such as Jason Moore and Dipesh Chakrabarty to argue that capitals exploitation of cheap nature, its treatment of everything into an externality, means that this standardization takes place against a globe that becomes more and more chaotic. Our common time is one of both unprecedented standardization and chaos.Morfino and Aspe's books represent two fundamentally different approaches to the transindividual, one historical the other critical, one ontological and the other phenomenological. At some point it might be necessary to work out the divisions between these two ways of looking at things, team transindividual will individuate and oppose itself in terms of Balibar Transindividualists, Simondon Transindividualists, etc., However, given the predominance of individuality, interiority, and intersubjectivity over our thought and practice, I am more inclined to let a thousand flowers bloom, exploring just what happens when one tries to think outside the individual, to think social relations beyond intersubjectivity.

These 1.3 mm wavelength observations revealed a compact asymmetric ring-like source morphology. This structure originates from synchrotron emission produced by relativistic plasma located in the immediate vicinity of the black hole. Here we present the corresponding linear-polarimetric EHT images of the center of M87. We find that only a part of the ring is significantly polarized. The resolved fractional linear polarization has a maximum located in the southwest part of the ring, where it rises to the level of ∼15%. The polarization position angles are arranged in a nearly azimuthal pattern. We perform quantitative measurements of relevant polarimetric properties of the compact emission and find evidence for the temporal evolution of the polarized source structure over one week of EHT observations. The details of the polarimetric data reduction and calibration methodology are provided. We carry out the data analysis using multiple independent imaging and modeling techniques, each of which is validated against a suite of synthetic data sets. The gross polarimetric structure and its apparent evolution with time are insensitive to the method used to reconstruct the image. These polarimetric images carry information about the structure of the magnetic fields responsible for the synchrotron emission. Their physical interpretation is discussed in an accompanying publication. © 2021. The Author(s).

The image polarization is determined by effects including the orientation of the magnetic field in the emitting region, relativistic motion of the gas, strong gravitational lensing by the black hole, and parallel transport in the curved spacetime. We explore these effects using a simple model of an axisymmetric, equatorial accretion disk around a Schwarzschild black hole. By using an approximate expression for the null geodesics derived by Beloborodov and conservation of the Walker–Penrose constant, we provide analytic estimates for the image polarization. We test this model using currently favored general relativistic magnetohydrodynamic simulations of M87*, using ring parameters given by the simulations. For a subset of these with modest Faraday effects, we show that the ring model broadly reproduces the polarimetric image morphology. Our model also predicts the polarization evolution for compact flaring regions, such as those observed from Sgr A* with GRAVITY. With suitably chosen parameters, our simple model can reproduce the EVPA pattern and relative polarized intensity in Event Horizon Telescope images of M87*. Under the physically motivated assumption that the magnetic field trails the fluid velocity, this comparison is consistent with the clockwise rotation inferred from total intensity images. © 2021 The Author(s).

We use here the M87* shadow size to infer constraints on the physical charges of a large variety of nonrotating or rotating black holes. For example, we show that the quality of the measurements is already sufficient to rule out that M87* is a highly charged dilaton black hole. Similarly, when considering black holes with two physical and independent charges, we are able to exclude considerable regions of the space of parameters for the doubly-charged dilaton and the Sen black holes. © 2021 authors. ; Support comes the ERC Synergy Grant "BlackHoleCam: Imaging the Event Horizon of Black Holes" (Grant No. 610058).

This polarized synchrotron radiation probes the structure of magnetic fields and the plasma properties near the black hole. Here we compare the resolved polarization structure observed by the EHT, along with simultaneous unresolved observations with the Atacama Large Millimeter/submillimeter Array, to expectations from theoretical models. The low fractional linear polarization in the resolved image suggests that the polarization is scrambled on scales smaller than the EHT beam, which we attribute to Faraday rotation internal to the emission region. We estimate the average density ne ~ 104–7 cm−3, magnetic field strength B ~ 1–30 G, and electron temperature Te ~ (1–12) × 1010 K of the radiating plasma in a simple one-zone emission model. We show that the net azimuthal linear polarization pattern may result from organized, poloidal magnetic fields in the emission region. In a quantitative comparison with a large library of simulated polarimetric images from general relativistic magnetohydrodynamic (GRMHD) simulations, we identify a subset of physical models that can explain critical features of the polarimetric EHT observations while producing a relativistic jet of sufficient power. The consistent GRMHD models are all of magnetically arrested accretion disks, where near-horizon magnetic fields are dynamically important. We use the models to infer a mass accretion rate onto the black hole in M87 of (3–20) × 10−4 M⊙ yr−1. © 2021. The Author(s).

We determine the polarization and Faraday properties of all VLBI targets, including Sgr A*, M87, and a dozen radio-loud active galactic nuclei (AGNs), in the two bands at several epochs in a time window of 10 days. We detect high linear polarization fractions (2%–15%) and large rotation measures (RM > 103.3–105.5 rad m−2), confirming the trends of previous AGN studies at millimeter wavelengths. We find that blazars are more strongly polarized than other AGNs in the sample, while exhibiting (on average) order-of-magnitude lower RM values, consistent with the AGN viewing angle unification scheme. For Sgr A* we report a mean RM of (−4.2 ± 0.3) × 105 rad m−2 at 1.3 mm, consistent with measurements over the past decade and, for the first time, an RM of (–2.1 ± 0.1) × 105 rad m−2 at 3 mm, suggesting that about half of the Faraday rotation at 1.3 mm may occur between the 3 mm photosphere and the 1.3 mm source. We also report the first unambiguous measurement of RM toward the M87 nucleus at millimeter wavelengths, which undergoes significant changes in magnitude and sign reversals on a one year timescale, spanning the range from −1.2 to 0.3 × 105 rad m−2 at 3 mm and −4.1 to 1.5 × 105 rad m−2 at 1.3 mm. Given this time variability, we argue that, unlike the case of Sgr A*, the RM in M87 does not provide an accurate estimate of the mass accretion rate onto the black hole. We put forward a two-component model, comprised of a variable compact region and a static extended region, that can simultaneously explain the polarimetric properties observed by both the EHT (on horizon scales) and ALMA (which observes the combined emission from both components). These measurements provide critical constraints for the calibration, analysis, and interpretation of simultaneously obtained VLBI data with the EHT and GMVA. © 2021.

We use an ultra-high angular resolution technique - global Very Long Baseline Interferometry (VLBI) at 1.3mm (230 GHz) - to resolve the innermost jet of 3C 279 in order to study its fine-scale morphology close to the jet base where highly variable-ray emission is thought to originate, according to various models. The source was observed during four days in April 2017 with the Event Horizon Telescope at 230 GHz, including the phased Atacama Large Millimeter/submillimeter Array, at an angular resolution of ∼20 μas (at a redshift of z = 0:536 this corresponds to ∼0:13 pc ∼ 1700 Schwarzschild radii with a black hole mass MBH = 8 × 108 M⊙). Imaging and model-fitting techniques were applied to the data to parameterize the fine-scale source structure and its variation.We find a multicomponent inner jet morphology with the northernmost component elongated perpendicular to the direction of the jet, as imaged at longer wavelengths. The elongated nuclear structure is consistent on all four observing days and across diffierent imaging methods and model-fitting techniques, and therefore appears robust. Owing to its compactness and brightness, we associate the northern nuclear structure as the VLBI "core". This morphology can be interpreted as either a broad resolved jet base or a spatially bent jet.We also find significant day-to-day variations in the closure phases, which appear most pronounced on the triangles with the longest baselines. Our analysis shows that this variation is related to a systematic change of the source structure. Two inner jet components move non-radially at apparent speeds of ∼15 c and ∼20 c (∼1:3 and ∼1:7 μas day-1, respectively), which more strongly supports the scenario of traveling shocks or instabilities in a bent, possibly rotating jet. The observed apparent speeds are also coincident with the 3C 279 large-scale jet kinematics observed at longer (cm) wavelengths, suggesting no significant jet acceleration between the 1.3mm core and the outer jet. The intrinsic brightness temperature of the jet components are ≤1010 K, a magnitude or more lower than typical values seen at ≥7mm wavelengths. The low brightness temperature and morphological complexity suggest that the core region of 3C 279 becomes optically thin at short (mm) wavelengths. © J.-Y.

En el artículo anterior recorrimos los aportes filosóficos del Romanticismo a la forja de los programas totalitarios del siglo XX. Señalamos también que la emergencia de esos movimientos no pudo ser posible sin el proceso precedente de desgaste de la ideología liberal. A ello contribuyó no sólo la vuelta de la monarquía de derecho divino, sino diversos desarrollos conceptuales que, en oposición a varios preceptos liberales, pusieron el acento en la libertad colectiva y en el particularismo cultural. En especial, dijimos que el historicismo decimonónico se había constituido como un movimiento que no sólo pondría en cuestión varios principios liberales sino que también desbrozaría el camino para las conceptualizaciones totalitarias. Dada esa importancia, conviene estudiarlo en profundidad. A. El discurso historicistaAunque los rudimentos del discurso historicista pueden rastrearse hasta la Antigua Grecia, siendo constatables incluso en algunos desarrollos de la Ilustración, el historicismo como tal, es decir, como postura epistemológica, no se desarrollará sino a partir de la Revolución francesa. Serán Johann G. Herder, Gustav von Hugo, Frederick Karl von Savigny y Frederick W. Hegel los padres fundadores de ese movimiento historicista que nace a posteriori de la Revolución francesa y que cosechará abundantes frutos a lo largo del siglo XIX y principios del XX.Ahora bien: ¿en qué consiste precisamente el historicismo? Esta escuela de pensamiento argumenta, en pocas palabras, que la realidad no es más que el resultado de su historia. Para la óptica historicista, la esencia de una cosa no radica en una supuesta naturaleza atemporal: radica precisamente en su desarrollo histórico. En la medida en que concibe a la realidad como una concatenación de hechos que se suceden unos sobre otros de manera inevitable, el historicismo, independientemente de cuál sea su forma doctrinaria puntual, tenderá a justificar todo lo que sucede en la Historia. Efectivamente, para el historicismo, la historia no narra un devenir errático o azaroso, sin propósito o sin sentido. El progreso no es accidental. Todo lo contrario. La historia está compuesta de "ritmos", "patrones", "leyes" o "tendencias" que pueden no ser evidentes a primera vista pero que están allí, guiando constantemente el devenir hacia su fin último o thelos. De allí que sea absurdo imaginar, diría un historicista, que en la historia haya espacio para el arbitrio, la contingencia o la fugacidad.En general, todo lo que acontece está pautado por los designios de la Divina Providencia (Vico y Hamann), de una Ley natural, del Progreso (Condorcet y los positivistas), del Espíritu Absoluto (Hegel) o de las Fuerzas Económicas (Marx).Este lenguaje historicista será incorporado a la retórica de los programas totalitarios de principios de siglo XX. Recordemos que Marx habla, más en conexión con el legado cientificista de Las Luces que con el Romántico, de "leyes objetivas de la Historia" y que Hitler, alineado con el más extremo irracionalismo, creyó haber encontrado "leyes naturales" que estarían detrás del ascenso histórico de la raza aria sobre todas las demás y, en especial, sobre la semita. Lo que es importante destacar aquí es que esta construcción historicista se dará de bruces con la propuesta liberal, no sólo porque el liberalismo había decidido explícitamente evacuar la historia de su propuesta, sino porque además postulará algo que era ajeno a la teoría liberal: la existencia de unsujeto histórico que será portador de una misión histórica.1. El sujeto histórico. Según el relato de "el progreso" armado por Las Luces, la ciencia, la razón y el conocimiento vendrían a mejorar no sólo las condiciones de vida materiales del hombre sino también sus condiciones morales y políticas. La historia era, para los ilustrados, una suma de hechos que en su conjunto narraban el triunfo de los derechos del hombre y de la independencia individual. Esta idea de "el progreso" se mantenía dentro de los parámetros de la propuesta liberal original, por cuanto tenía en el centro de la escena histórica al individuo o, en todo caso, a la humanidad toda.Sin embargo, para el historicismo del siglo XIX, el sujeto primordial de la historia no va a ser ni el individuo ni el Hombre, como tal. Vendrán a ocupar ese lugar entidades mucho más amplias: como son el Estado o la Nación. Esta conceptualización fue acuñada, a modo de ejemplo, por Herder y Hegel, para quienes el desarrollo de la Nación y del Estado, respectivamente, son los que, precisamente, explican el progreso de la Historia universal. Con ese énfasis en la predominancia de lo colectivo en el acontecer histórico, el historicismo procedió a rehabilitar la visión organicista de la sociedad, contra la cual habían luchado en consuno tanto el liberalismo como la Ilustración. Ya enfundado en un formato totalitario, este historicismo implícito en la lógica de "El capital" de Marx y de "Mi lucha" de Hitler adoptará como sujetos históricos al proletariado y a la raza aria.2. La misión histórica. No sólo reemplazará al individuo por supra-entidades, este historicismo, le asignará a esas supra-entidades, supuestamente encargadas de hacer girar las ruedas de la historia, una determinada misión histórica. Es decir, esas entidades no sólo son responsables del devenir histórico, de "empujarlo", sino que además tienen el encargo de llevarlo hasta su realización última. En otras palabras: esa supra-entidad es la que vendrá a poner punto final al largo recorrido histórico. Tal centralidad se le confiere a esa misión histórica,que se concibe que todo el desarrollo histórico anterior era tan sólo un preámbulo de ése momento excepcional que se anuncia, con bombos y platillos, como el "fin de la historia".En el caso del comunismo marxista, es al proletariado, al que le es encomendada la tarea de llevar a cabo el propósito de la historia: a saber, abolir la sociedad de clases y reemplazarla por una sociedad igualitaria, desembarazada de cualquier forma estatal. Del mismo modo, en el caso del nacionalsocialismo, el sujeto histórico, el "volk", mezcla, como veremos, de raza y nación, tendrá como misión histórica lograr la llamada"asepsia racial" y coronarse como la raza dominante.Es importante señalar que esa "misión histórica" no es meramente la descripción de un hecho pautado por "normas", "leyes" o "fuerzas" superiores. En realidad, reviste la forma de unimperativode orden moral al que el sujeto histórico debe responder y asumir. Es así que el proletariado hará la revolución en nombre del comunismo y el "volk" alemán en nombre de su supuesta superioridad racial.Hasta aquí hemos recorrido el tronco común que emparenta filosóficamente al comunismo con el nacionalsocialismo y el fascismo. Sin embargo, el nacionalsocialismo será portador de un concepto que no sólo lo distanciará considerablemente de la filosofía comunista sino que jugará un papel central en su ideología. Nos referimos al concepto de "volk", que veremos a continuación. 2. C onstruyendo el "volk" nacionalsocialistaEl comunismo marxista fue en gran medida hijo de Las Luces. Su construcción teórica está hecha con materiales procedentes de la vertiente racionalista pregonada por los ilustrados. Buena parte de su visión del funcionamiento de la economía se basó en la reflexión legada por la Ilustración. Smith y Ferguson, a título de ejemplo, fueron para el filósofo alemán figuras no sólo influenciantes sino dignas de admiración. Su socialismo se nutrió, entre otros, de las propuestas de Bonnot de Mably y de Saint Simon, personajes ambos comprometidos al movimiento ilustrado. El ateísmo recalcitrante que exhiben las obras de Marx nace seguramente de la aguda crítica de los "philosophes" al cristianismo y a la religión en general –amén del heredado por el antropólogo Ludwig Feuerbach -. Lo mismo es válido para su visión materialista de la realidad. Es ampliamente conocido que Diderot y d'Holbach, dos de los ilustrados más agudos en su crítica a la religión y más afiliados al monismo metafísico de Spinoza, se encontraban entre las lecturas recurrentes de Marx.Por otro lado, la idea marxista de que la historia se rige por un puñado de "leyes objetivas", brota del intento ilustrado de darle cientificidad al estudio histórico, siendo, a la vez, una versión radicalizada de "el progreso" y de la dialéctica "ultra-racionalista" de Hegel. En su intento por superar a Las Luces, el comunismo marxista caerá en un racionalismo intolerante y en un universalismo excesivo, que terminará en los gulags, en el Holodomor y en la Primavera de Praga. Ése legado iluminista es menos notorio en el fascismo italiano y en el nacionalsocialismo, que son, más bien, feudatarios del Romanticismo. Tal es el caso del concepto de "volk", que, como veremos, el nacionalsocialismo extraerá y re-trabajará de algunos autores románticos.La idea "volk" se confeccionará, a lo largo del siglo XIX y principios del XX, a partir de varias ideas y corrientes de pensamiento provenientes de los más diversos ámbitos, desde la filosofía hasta la biología. Veámoslo en detalle y dilucidemos sus diversas fuentes. 1. Los orígenes románticos. La idea de "volk" nace de quien, según algunos autores, fue el primer "romántico": Johann G. Herder. Traducido literalmente del alemán, "volk" significa "pueblo". Pero el significado atribuido por Herder a dicha palabra va más allá. En el lenguaje del filósofo alemán, el "volk" hace referencia específicamente al conjunto de valores culturales que definen a un determinado colectivo humano y que lo diferencian de otro. Para ilustrar esa idea, Herder recurre a una analogía: así como los individuos poseen un alma, así también, el pueblo, que es una suerte de individuo amplio, posee una. Esta alma, o "volkgeist", se despliega a través de la historia y se plasma empíricamente en cosas tan variadas como el arte, la religión, las leyes y, en especial, el lenguaje.Si bien en Herder los distintos "volk" eran totalidades culturales, el autor se resistía a que se organizaran en Estados, dado que esto, argumentaba, desvirtuaría su carácter natural y conduciría a la discordia y al enfrentamiento. Asimismo, Herder rechazaba toda asimilación de Nación con raza. Es por ello que, aunque Herder es efectivamente el padre de la idea de "volk", bajo ningún concepto puede endilgársele a él las catastróficas consecuenciasa las que dicha idea llevó de la mano del nacionalsocialismo. El "volk" de Herder está virgen de todo contenido absolutista y belicista: nada más alejado del nacionalismo despótico y bárbaro profesado por el nacionalsocialismo. El concepto de "volk", más bien, Herder lo esgrime contra lo que considera es un universalismo y un racionalismo ingenuos y, en algún punto, peligrosos para la pluralidad.Además de Herder, el filósofo idealista Johann G. Fichte contribuiría a acentuar la idea de un "volk", sobre todo, de un "volk" alemán. En efecto, el autor enunciaría en sus "Discursos a la nación alemana" la superioridad natural de los alemanes frente a los franceses, pese a haber sido derrotados por estos militarmente. El llamado que hace Fichte a Alemania está dirigido a lograr construir la unidad de esa nación que, aún luego de caído el Sacro Imperio Romano Germánico, y hasta la unificación en 1871 concretada por Otto Bismark, permaneció dividida en diversos reinos, principados y Estados. La idea de Fichte era apelar a la unidad espiritual de los alemanes en vista de su aparentemente irremediable fragmentación política y económica.2. El corporativismo . Es verdad que ya en Herder el individuo era definido en función de su pertenencia a la comunidad. Pero también es verdad que en ningún momento el autor esboza una mirada corporativista de la comunidad. Es decir: según él, los individuos se han de entenderdesde la comunidad pero ésa comunidad no puede de ningún modo acabar con imponérseles. Sin embargo, poco a poco, esa idea originaria de Herder transitaría otros rumbos que desembocarían en la supresión de la individualidad en favor de la comunidad.Quizás haya sido Hegel el primer filósofo en elaborar una teoría estatal-corporativista del "volk", desarrollada en su "Filosofía del Derecho". Su visión dialéctica de la historia llevó al filósofo alemán a concebir que el último estadio de la realización histórica se concretaría en el Estado. Efectivamente, para Hegel, todos los intereses individuales son finalmente superados en el Estado, quien pasa ahora a ser la encarnación de aquellos valores supremos vinculados al bien común. De esa forma, los individuos, concebidos por Hobbes y Locke como unidades relativamente autónomas, dejan de serlo para identificarse con esa entidad éticamente superior, que es el Estado. Se deslizó así la idea, de vocación proto-fascista, de que el individuo es un ser subordinado por entero a los fines del Estado. En efecto, con esa visión, Hegel echará las bases de la teoría fascista del Estado, elaborada por Mussolini y Gentile para los años 20. Esta visión corporativista se desarrolla en oposición a la visión liberal. Se entendía que la sociedad no era una agrupación volitiva de individuos sino una compleja amalgama de instituciones sociales, de organizaciones políticas y religiosas, etc. que responden a un determinado desarrollo histórico y que, por tanto, son anteriores a cualquier individuo. El corporativismo decimonónico visualiza como peligroso al liberalismo por considerarlo como una ideología divisoria al estar centrada en el individuo a secas. En contraposición, se promueve a la "nación" o al "volk" como las entidades que permiten la "síntesis" y "superación", para ponerlo en lenguaje hegeliano, de toda fragmentación individualista y de toda tipo de confrontación, como la que llevaba implícita el comunismo revolucionario con su acento en la lucha de clases.3. Los aportes de la geopolítica. Al lado de ése rampante corporativismo, surgió a principios de siglo XX, con la publicación de "Introducción a la geografía sueca" (1900) de Rudolf Kjellén, una disciplina que, utilizando una dudosa epistemología que combinaba política con ciencia natural, se aprestará a estudiar al Estado, no como una realidad de orden social o cultural, sino como una de índole natural. El Estado, en otras palabras, será visto por esta corriente como un ser vivo. Nace así la llamada "geopolítica". Aliándose con el vitalismo filosófico de Nietzsche, Dilthey, Bergson, y en sintonía con las tendencias corporativistas, esta disciplina, de pretendida vocación "científica", verá en los diversos desarrollos de la sociedad procesos similares a los de cualquier organismo vivo. Es así precisamente que, para los geopolíticos, el Estado está destinado, porque así lo pauta la propia biología, a nacer, madurar y morir.Sin adentrarnos en detalles que no vienen al caso, lo que importa subrayar aquí es que esa visión geopolítica del Estado sirvió de justificación teórica para ciertas prácticas del nacionalsocialismo. En efecto, si el Estado es un ser vivo, entonces, como cualquier otro, necesitará expandirse si quiere crecer. Así, la adquisición de nuevos territorios, la colonización y hasta la guerra pasaron a ser vistos, no como decisiones políticas cuestionables, sino como imperativos de orden "vital". Bajo esa óptica, el imperialismo de algunas potencias europeas, en boga durante la segunda mitad del siglo XIX, era interpretado como signo de "buena salud". Un Estado que no amplía fronteras es como un individuo que no crece: está destinado a morir. Los límites de un Estado deben ser, por ello, cambiantes. Según si sus fronteras están o no en expansión, se diagnosticará si el Estado está en una etapa de crecimiento o de decadencia. De allí la idea de "espacio vital"– o "lebensraum"-, elaborada originalmente porFriedrich Raztel, y que fuera adaptada por el teórico naziKarl Haushofer a los fines de una Alemania que comenzará a expandirse y anexar territorios circundantes.4. El mito de la raza.A todas esas tendencias, se le sumaría a la idea de "volk" el componente racial. Aunque hubo otros, sin duda el primer texto que ejerció una influencia considerable sobre el desarrollo racista del "volk" será el "Ensayo sobre la desigualdad de las razas humanas" (1853-1855) de Joseph Arthur de Gobineau, en donde se proclamaba livianamente la superioridad de las razas blancas sobre las negras y semitas en términos de fuerza, belleza e inteligencia. En realidad, la obra de Gobineau no sólo se hacía eco del ideario de la geopolítica sino también de algunos conceptos que una in status nascendi antropología traía consigo.Es cierto que ya en el siglo XVIII, como producto de la expansión de la ciencia hacia otras áreas del conocimiento, aparecieron las primeras clasificaciones raciales del hombre. Dos personalidades se destacaron a ese respecto, como fueron Buffon, Linneo y Blumenbach. Sin embargo, ésa clasificación no conllevará todavía ninguna imperativo ético. El fin era conocer, no valorar. Pero ello cambiará diametralmente para el siglo XIX.La idea de que una raza es "superior" o "inferior" porque es portadora de "mejores" o "peores" componentes biológicos, emergerá asociada a un tipo de antropología-sociología, de cuestionable estatuto científico, que intentará transpolar la teoría evolucionista de Darwin a la esfera social. Aunque falazmente, se concibió así que, dentro de la sociedad, sólo triunfan aquellos individuos "más fuertes". Del mismo modo, en lo referido a las razas, se afirmará la existencia de una jerarquía natural: hay razas superiores e inferiores, amas y esclavas. Por eso mismo, los socialdarwinistas, ya consolidados como ideología política más que como una disciplina de carácter científico, rechazarán el mestizaje por considerarlo una perversión antinatural que va en detrimento de las razas "superiores". Con el mismo argumento, se resistirá al liberalismo, al igualitarismo y al internacionalismo. Estos aportes socialdarwinistas y racistas trabarán alianza con el explícito organicismo de la geopolítica y, de esa forma, se completará la tríada en la que versará toda la ideología nacionalsocialista: "suelo, sangre y raza".Por supuesto que mucho antes el discurso antisemita ya había echado raíces, no sólo en Alemania sino en gran parte de Europa. Aunque no exclusivo del siglo XIX y XX -baste recordar la decisión de Isabel la Católica de expulsar a los judíos de España en el siglo XV-, el antisemitismo se vio acentuado exponencialmente. En efecto, anteriormente, las naciones europeas vieron como una "solución" a la situación de los judíos el fomentar su reeducación religiosa, como propuesto en su momento Lutero. Pero, conforme los paradigmas biologistas y organicistas se afincaron en el ideario político y social, se convino en señalar que lo de los judíos no era un "problema" religioso sino biológico. Es así que el autor inglés Houston Chamberlain se permite decir:"[Que]la corrupción de la sangre y la influencia desmoralizadora del judaísmo, he aquí las causas principales de nuestros fracasos." Tachados de "inferiores", los judíos empezaron a ser vistos como una amenaza para aquellas naciones racialmente "puras", como Alemania.El triste derrotero de todas estas conceptualizaciones ya es por todos conocido. *Licenciado en Estudios InternacionalesProfesor de Polìtica ComparadaDepto. de Estudios InternacionalesFACS, Universidad ORT Uruguay

Mr. John Fiske writing his essay on Les-. sing's "Nathan the Wise," in 1868, said: "The fame of Lessing is steadily growing. Year by year he is valued more highly and valued by a greater number of people. And he is destined, like his master and forerunner Spinoza, to receive a yet larger share of men's reverence and gratitude when the philosophic spirit which he lived to illustrate shall have become in some measure the general posses-sion of the civilized part of mankind " I confess to a very warm admiration for the man, and for much of his critical work in art and literature. Lowell's characterization is so ipt, that I would not mar it by an attempt at •esh expression. He says : "In the history if literature it would be hard to find a man so italwart, so kindly, so sincere, so capable of ;ieat ideas, whether in their influence on the intellect or the life, so unswervingly true to e truth, so free from the common weakness his class. Since Luther, Germany has given lirth to no such intellectual athlete, no son so ■erman to the core. Greater poets she has ad, but no greater writer; no nature more I finely tempered." Much of Lessing's work is still significant. His early attacks on the pedantry of poor Gottsched's French classicism, his denial of Corneille and Ractne as proper models for the German drama, his seizure of the secret of ] Greek sculptural expression, was all true and I enduring work. His leadership in the true classical revival was healthful. His contribu-tion to Germany's awakening national life, in his dramas of Mina and Emilia, was ennobling and abiding. For all this critical and con-structive work-, he had an established basis in thought. His service in this sphere of intel-lectual life was constructive, and ended in something specific and satisfactory. Even his critical disputation with the irate theologian Goeze, was helpful to genuine scholarship, de-spite its negative results, because, it was, at heart, a fight for freedom of Biblical investiga-tion. But, if as a man, and a critic of art and lit-erature he still holds so large a place in mod-ern thought; as a thinker on ultimate prob-lems, I do not believe, Mr. Fiske to the con-trary, that Lessing's philosophical spirit is sat-isfactory to serious men of either the religious, or scientific type. Lessing's memorable trib-ute to *the inherent superiority of the search for truth, to the truth itself, is a brilliant ex-pression of his philosophic spirit. "Not the truth of which any one is, or supposes himself to be, possessed, but the upright endeavor he has made to arrive at truth, makes the worth of a man. For not by the possession, but by the investigation, of truth are his powers ex-panded, wherein alone his ever-growing per-fection consists. .Possession makes us easy, indolent, proud. If God held all truth shut in his right hand, and in his left hand nothing but the ever-lasting instinct for truth, though with the condition of forever and ever erring, and should say to me 'choose!' I should bow humbly to his left hand, and say, 'Father, give ! pure truth is for Thee alone !' " In the first half of this confession of his philosophic attitude, Lessing expressed a noble 65 THE COLLEGE MERCURY. fact—the worth and joy of intellectual con-quest. But, to declare that endless bafflement, in the search for truth, is the thinking man's true paradise, is contrary to the aim of both genuine science and religion. Life and eter-nity are facts too momentous for us mortals to be forever playing blind-man's-buff in. Truth for Lessing was not a fixed point, it was only an endless advance toward such a point. To have arrived there, he declares, would have been a disappointment. Was Lessing right? This attitude in his philosophy of life arose from a limitation of his nature. Lessing was preeminently a critic. His dramas, though full of action, lack inspiration. He had poetic and constructive ability, but for any probing into that realm beyond the palpable phenom-ena of life, or any emotional craving for a spiritual transformation through worship of the divine—to both the scientific and religious quest for ultimate truth, he was largely Pagan. It is one thing to believe with a regretful agnosticism, that the ultimate force behind all phenomena is unknowable, and to declare with Lessing, that we would rather have the search, than to meet the eternal mystery face to face. And yet, many of Lessing's admirers claim him not only as a theist, but as a Christian, and this, despite his declaration to Jacobi, in 1780, that he was a disciple of Spinoza—the master pantheist. Just how such different views of Lessing's Christianity arose becomes clear if we keep in mind what he considered Christian, and what the best minds have cen-tered on as the essence of the Christian faith. To understand Lessing's satisfaction with the endless search for truth we must discover his idea of religion and Christianity. For him, there was no absolute religion. All religions contained truth, as much truth as the age, in which they were helpful, could apprehend. As the different races progressed in intellectual and moral culture, their theologies and moral-ity became more spiritualized and considerate. The noblest expression of the religious life, he found in Judaism, as expanded by Jesus. Les-sing claimed to believe in the religion of Jesus, but not in the Christ of Christianity. It was the religion of "goodness," which Jesus taught, that always commanded his reverence. Berthean says: "If this so called religion of Christ is the true Christianity, then' Lessing was certainly a true Christian, a Protestant in the full sense of the word ; and he has carried further the work of Luther. But if on the other side, those are right, who. on the in-stance of Schleiermacher, consider the personal relation to the person of the Saviour, and not the doctrinal system, as the essence of Chris-tianity, then Lessing was, in spite of the deep veneration which he always nourished for Jesus of Nazareth,rnot a Christian man." Still, in his "The Education of the Human Race," his last religious testament, Wackernagel, Stirm and others think they have discovered a decided progress towards Christianity. The truth seems to be, that, even at the end of his life, Lessing's theological standpoint was still in the process of formation; that is, unfinished, unsettled. I can not help but feel that this Wandering Jew choice is neither sane, nor pro-found. Making all allowance for St. Paul's; vivid conviction of Christianity's truth, the attitude of Lessing recalls the Apostle's de-scription of certain Greeks who "were ever learning, but never able to come to a knowl-edge of the truth." Christ insisted upon calling himself "The Truth." The central truth of Christianity is neither its ethics, nor its body of divinity, hut the personal Christ—the supreme revelation ol God's person and love. For the ethics of Jesus, and His spiritual kingdom, Lessing had unbounded admiration. But admiration is lid adoration. That the highest truth is incar-nated in a perfect personality, Lessing seems] to have missed. Here, at the heart of Christ we are promised, and do receive, rest; after the-long quest for truth. Augustine, who ffl quite as profound, and as well acquainted witt life as Lessing, was glad to end his search ifl the rest of God through Christ Jesus.

' his I \\::: .led, this] pro-1 ml'sl the I del l'\Y IV,'.- Thel tyisl , but] DIIO!| :s ■hi Is noil (near leeii'l fcrri: |r tbel vn I ffiffl ii i: Anl llini: Mr. Gibson is without doubt the greatest I illustrator of the day. There seem to stand out, among the multitude of illustrative art-fists who are now making our literature doubly I interesting by their delightful pictures, two [.■whom the world acknowledges to be the fore- Imost, Charles Dana Gibson, of the United [States, and Phil May, of England. Of these, [Mr. Gibson, by general consent, holds the first iplace in the eyes of the English as well as the : American people. For us Americans at least, there would be no great difficulty in saying why Mr. Gibson has thus received this preference over Phil May. While the drawings of Mr. May, dealing as they do, with the children of the poorer class of England, are delightfully unique | types of the London street urchin, yet they seem to lack that refined tone notice-able in all of Mr. Gibson's work. It is a marked feature in the work of many illustrators that the excellence of their execu-tion varies from time to time. Not so with [our artist. True, we ma}7 say of one of his [drawings, as in contrast with another, "This is better ;'' but when we analyze our reason why ye think so, it comes out every time that it was j the subject matter, and not the execution of it, that lead us to say, "This is better." This leads to the remark that Mr. Gibson's 'ideas" for his pictures, blending with his charming manner of execution, constitute the jreat attractiveness of his work. This is es-pecially noticeable in his work for "LIFE." ■Sis centre double page drawings in this pub-lication are always the expression of some up-to- date, interesting idea or fashionable folly; portrayed for us in a realistic and impressive vay that words could never do. He seems to Jo more head work than any of his contempo-raries, and it is this that interests us so greatly in his work. In the last few years he has confined him-self, besides his work for "LIFE," to the illus-trating of stories, chiefly those of Mrs. Burton Harrison and Richard Harding Davis, to those of the latter to a greater extent in recent years. The charming adaptability of Mr. Gibson's drawings to Mr. Davis' stories is but another expression of the close friendship and similar-ity of thought existing between the two men. It has been said of Richard Harding Davis and his novels that they are "fresh, free, graceful and virile." They are four adjectives well chosen, and not one too many, and it is remarkable how perfectly transferable they are between the author and his personal friend, the artist. Both these men, in their several crafts, are, as every one knows, in exceptional degree interpreters of the cultivated life of our own immediate day and country, not with oversight of its foibles and vices, but also in all its young and joyous health and beauty, its improved understanding between the youth of both sexes, its manly and womanly natural-ness, the kindness of its sun-and-breeze gayety and candor, and the unparaded earnestness of purpose and principle which so frequently un-derlies this laughing surface. This is said with Mr. Gibson's work the more pointedly in mind, and but enumerates the characteristics which tend to give it its pre-eminent and uni-versal popularity. Doubtless a great proportion of Mr. Gibson's admirers are more familiar with his illustra-tions than with the personality of the artist. He is no less interesting than his drawings. Charles Dana Gibson is a tall, smooth-faced, athletic looking man, not yet thirty years of age. The impression he makes as he leans back in his chair and talks of art, books, travel and kindred matters is that of a man upon whom success has cast no pernicious influence, a man whose inherent modesty has not been destroyed by the applause of a noisy world; one whose own personality furnishes the naivete of his fascinating drawings. He is frank without being brusque, dignified but not ■'illi'-ii'.imwm 67 THE COLLEGE MERCURY. cold, self-poised but not egotistical. So says Van Zile, in Current Literature. Mr. Gibson is a student of literature, es-pecially liking Thackeray who understood art-ists. Yet of course, as an illustrator in heart-iest sympathy with the thought and feelings of his own times, he feels obliged to keep in touch with the best work of the day, and ex-presses great admiration for the work now be-ing done in fiction by several young American authors, prominent among whom, of course, he considers Richard Harding Davis. Van Zile says of him: A feature of Mr. Gibson's fame which must be a source of the happiest pleasure to him, is the unanimity with which writers, artists, critics, editors, and the great reading laity of all ranks and orders, concede his power and charm. There seems to be but one verdict as to his place as an artist. His technical skill, his concientious study of con-temporary life, his sympathetic insight, his charming ability to tell without violence to truth, what he wants to tell, while he leaves all else untold, and his absolute wealth in that indefinable but essential quality which gives the distinction of individuality to the work of an artist, have combined to set him, before he is yet thirty years of age, in the very front rank of contemporary illustrators. THE TREASURE OF LAKE DEMBEA. John Streslow, physician of Middlesex, was so fortunate as to be named sole heir to his grandfather's estate. John Streslow, senior, gave to his grandson, besides his money, a taste for travel, which that young man had hitherto been unable to gratify. Therefore, it was natural for him to be very happy over the prospect of years in foreign lands. The estate to which he had succeeded lay along the Hudson not far from New York, and, of course, before long Streslow, from his constant association with the men of the city, was elected a member of one of its leading clubs. His intention was to remain at home for a year, and then leave for an indefinite period. A strange find one day altered his purpose. While looking through his grandfather's papers he happened upon two rolls tied to-gether with a leather thong. The one was of parchment, and on it was a diagram of an in-terior portioii of Egypt, about the sixth cata-ract of the Nile, and some strange characters of a language unknown to Streslow. The other roll was of paper, and was a translation of the former, stating that by following the route laid down in the diagram, one would) find a kind of stone with the power of partially overcoming gravity ! To the young man, whose mind had always been of a scientific turn, this idea was especially captivating, and he at once determined to sail within the I month, and announced his intention at the| club next evening. "To Egypt?" asked a young fellow. ''Yes,I to Egypt," answered Streslow. "And I ain| going with a purpose; too." "Perhaps you will bring back a treasure,'11 suggested another sneeringly. "Perhaps," was Streslow's only reply. And so, about two weeks after, the men the club were somewhat surprised to find th their friend had persevered in his intention,! and that he had really sailed for Egypt. He took the shortest possible way and al-| lowed nothing to draw him away from grand object of his search. Three weeks afterl leaving home he found himself at Alexandria,! where he hired an intelligent guide, and niadel ready for his journey up the Nile. Theyl reached the village Senuar on the banks of tliel Blue Nile, and set out at once for Lake Demi bea among the Talba Waha Mountains. Theyl travelled alone, for fear of possible danga| should their errand be known. By following the chart carefully they their way but twice in all the twenty-fi«l miles. A week's travelling through mani difficult places and with varied adventures brought them to the grotto specified. It wa| a long, irregular opening in the side of a clifl just a little above the surface of a small pM I THE COLLEGE MERCURY. 68 • I iiatl all the! ifterl iri ladel 'till icivi lie; :igfl| lo| tanl Lire] id which ran down to the shore of the lake. AH remained outside while Streslow made some investigations. The entrance grew higher but [narrower as he advanced, and a short pas-sage way brought him to a large rock-hewn room. He called Ali to bring material for [lights, and soon the ceiling and walls were shining with many colored splendor. A nurn- Iber of rocks were strewn about. From the Barge room several passage ways led into [deeper recesses. Following the one indicated [Streslow soon came to a larger room than the prst, but the floor of which appeared to be tiled. [The rock seemed to be a kind of granite, with (very distinct white and black markings. With Ihis first step upon the level floor Streslow felt fa strange sensation of lightness. He nearly (fell forward on his face, and to save himself he [put his hand against a rock, which rolled [away from him like a hollow rubber ball. He leaped in the air and barely escaped knocking lis brains out against the roof of the cave. iHis weight was as nothing. He had found Ithe treasure ! And now taking two pieces or llayers of the rock, which was of much the jsame formation as slate, he made his way to the light again and back to Sennar. The chief and his people received him [kindly, crying in their language, "Hail, stranger," and conducted him to a hut near pat of the chief, where he was waited on by some of the chief's slaves. There were some sick in the village, and |hat evening just at sunset the priest of the ribe invoked the Sun God for them, standing upon a block of this wonderful stone. Both Bi and Streslow noticed it, and Ali scented danger, if they should be discovered, for he mew that the people considered this stone the rift of the Sun God himself, and they consid-ered that any one who did not worship him tiad no right to its possession. While lying in their hut that night, before ?oing to sleep, Ali was acquainted with the act that they should have to leave the village pder cover of the darkness. And when every-ting was still, and all were asleep, as they thought, the two stole forth toward the river. But one of the servants of the chief saw the stone, and a guard was set, so that the two men had hardly reached the river until all the village was aroused and in pursuit. Arrows and spears fell all around them as they made their way down stream, but fortunately they escaped safely, and before many days reached Alexandria. Streslow arrived at home in good time and that same night dropped in at his club, to the surprise and delight of his friends, who were at once eager to hear the account of his travels. Friday night of the same week was set for his story and for the exhibition of his "treas-ure," of which he had very briefly told them. When the time came the rooms were crowded, and at the proper time Streslow re-lated the incidents of his journey as we al-ready know them and exhibited the wonder-ful stone in regard to which there was so much expectancy. But, wonderful to state, whether on account of the influence of the at-mosphere of unbelief that pervaded the club, or from-some other cause, the stone had lost its power, and had it not been that Streslow was a man of untarnished reputation he would have been dubbed a second Muuchausen then and there. He gave them a speech instead of an experiment. "I am not to blame for the failure to-night. A month ago that stone did what I claimed for it. Perhaps the change in climate accounts for the loss of its power. But I am ready to take the tour to Egypt again, with any man or men to prove that there lies a wonderful power in the treasure of Lake Dembea." His words drew the applause of the mem-bers, but no one was willing, nor has anyone since been willing, to risk life and fortune merely for the sake of annoying nature. A girl, a wheel, A shock, a squeal, A header, a thump, A girl in a lump, A bloomer all torn, A maiden forlorn. ■■■■■■■^■■■■■■■■■■■iHHHBB 1 69 THE COLLEGE MERCURY. 'TEAGIC FEAGMENT (?)" "Men may come and men may go But I go on forever." "Boast on, oh dancing Tiber In this cheerless rainy weather ! But when this season passes, And the drought of summer comes, Or chilling blast of winter Your shallow stream benumbs; No more will voice be left you To sing your vaunted song ; No more be heard your boasting As you gaily prattle on." ******** Thus mused the college senior, In a vein so new and strange, And so very unaccustomed To his usual narrow range, That he stopped and slightly started From his state of sad depres-ion, That a hardened chap like he was To such thoughts should give expression, And should think it worth his while To abuse this little way-sb earn, Which had seemed almost too trifling To be subject of his day dream. Yet while he sought to chide it, As though a naughty elf, He knew, in cvcri/ sailertCe, He was thinking of—HIMSELF. COLLEGE LOCALS. C. E. FLECK and J. H. MEYER, Editors. Good Bye ! Exit Ninety Seven. Examinations—not "exams." Two straight games from State—we're all right. The Sophomores manifest the usual activity in collecting Botany specimens—they may be seen on the search for specimens almost any fine afternoon. One of them was heard to say he could analyze a flower in five minutes— quick work. "Earnie" has great difficulty in getting to-gether the members of the Athletic Associa-tion. This reminds us of some other things around here. Niels L. J. Gron, '93, who recently visited here, contemplates a course at Oxford. He is a firm friend of the MERCURY, and will write us something on University life there. The Freshman Glee Club have been recently dispensing their melodious strains over the campus. ' 'Music hath charms.'' We have now another track to cross at the Reading Depot as we go to meals. Surely there should be flagmen there now. Senior dignity is still more in evidence as Commencement approaches. We may look for a general cleaning of rooms this week. The duties and pleasures of the coming va-cation form an absorbing theme for thought just now. A Senior speaking of a certain game re-marked : "I would like to say confidentially that the chances for success are very probable." The members of the Omega Delta society have come out with new pins. They make a nice appearance. A Seminarian is now giving lessons in kick-ing. Lying on his back, he kept a swing at bay with his pedal extremities for fully five minutes. His dignity is the only thing that suffered from the experience. The real college life of old Pennsylvania be-comes more apparent as Spring advances. No matter how pressing work may be, the boys find time to linger on the campus for a few minutes before going to their rooms of an evening. This is one of the phases of college life which many of the Alumni remember with pleasure. It is a fine custom. In Physics one day, when the class was about to write a paper on the torsion of the wires holding two eggs, a bright fellow was heard to remark : "Which is the spoiled egg?" Dr. N. answered with a chuckle: "That will appear when your paper comes in." It was several degrees cooler for some minutes thereafter. Dr. S.—"Mr. K., what secretes the saliva?" K., '00—"The gastric juice." A nine from Seminary played the Sopho-more class team Saturday, May 22nd. The game was exceedingly interesting, but was without any special features, except error; Inasmuch as the runs on both sides were too many to be counted, no one tried to give an official score. It is but natural for us to feel somewhat east down in spirit when we learn that we shal have to work Ascension Day, this year. Itii only a church festival, but this is a church i& stitution, and no pressure of work ought to be allowed to displace service on that day. W should have at least half the day to ourselves. THE COLLEGE MERCURY. 70 at ve an itli The Seniors finished their work with an ex-amination Tuesday Morning, May 25th, and The course of '97 in college is ended. The Mass is jolly and jovial, and there is not a man in college who does not hate to see them leave lis. May they have much success in life, is the wish of the MERCURY. D., '00, (seeing posters announcing a straw- Berry festival)—"Is this Senior L. T. L. the Senior class of College or of Seminary ? '' From all accounts the new dormatories are kn assured fact. The buildings will be in the Kyle of English cottages, each a memorial to the donor. We understand that two are promised. These neat structures will improve the appearance of the campus very materially. ■)ne need not question the fact that Pennsyl-vania College is growing. I Prof. H.—"Mr. S., who were Hale and Arnold.

A marked lharacteristic of the book is its originality. I |he Spectrum reflects great credit upon the 1 Bass of '98. Earlier in the month an excursion party of '. jeologists- from the leading universities of | America, paid a visit to the battlefield in honor j H Sir Archibald Geike, the most eminent ge- i llogist of England. They were here only a I Jiort while and spent all their time viewing ! lie field. The Senior tour to the Euray Caverns did I jot materialize. Many expressions of regret ' have been heard. During the past week Professor Himes agree-ibly surprised the Sophomores, who were ut-rly unprepared for the recitation, by voluu-ering to give them a lecture on the "Edu-tional Value of Poetry." The lecturer was ven the strictest attention, and the favorable marks about it show that the class appreci-ed the talk very much. They would not be verse to spending many an hour in like man-lhe Businessmen's League, of Philadelphia, lent last Saturday and Sunday in town. They lid a short visit to the College, but spent lost of their time on the battlefield. Some in of influence in railroad circles accompa-lied the party. A few weeks ago a crowd of Freshmen vis-ited the "haunted house" near New Oxford, and spent the night there. There was much throbbing of hearts whenever squeaking of doors or windows would occur, and a general silence at louder noises. All the boys were not so timid, however, and some managed to sleep a while. Perhaps the number of visitors compelled the ghosts to withdraw, for there was no appearance of spirit forms. We ad-mire the nerve of the Freshmen. Some of the men of the College have taken to horticulture. The line upon which they ex-pend the most energy is raising onions. We very easily obtain a knowledge of this fact by means of the odors which exhale from the lungs of those engaged in the business, and by the tops of onions which are strewn through the halls a number of mornings in a week. Onions and fresh water crackers do taste good at night. The fact that we shall have examinations on Decoration Day is raising a great deal of feeling among the boys. Every hour of a National holiday is each man's own, to use as he desires. Of course we cannot have it other-wise than it has been decided. Perhaps next year we will have a holiday or two. Commencement week with its gayeties is casting its shadow before it, and is throwing its spell over the students. This is the com-ing season of the whole school year, and one is amply repaid for remaining. The week will be rendered livelier by class reunions, and other events of like character. Let all who can, remain. The concert by the Glee Club, on Tuesday night, will be better than it has been in former years. One can spend a pleasant evening listening to our own musical organizations and be well repaid. /\LUlV|Nl- R. L. SMITH and J. H. BEERITS, Editors. '40. D. J. A.

Base-ball, of course, has been the all absorb-ing form of athletics this month; and the rec-ord of the club has been an excellent one. That we have had a team to be proud of every-one admits, aud we are glad to see the interest that the boys have taken in it. INDIANS—First game.

CLARIS, Editor. It is very unfortunate that, as soon as the pleasant days and evenings begin to arrive, the attendance at the meetings of our literary societies should decrease so markedly. There is no excuse for such a state of affairs; our halls are both very pleasant to be in on these spring evenings, and we are sure the members need the literary drill just as much now as at any time. There seems to be a general tend-ancy among the boys to give literary matters a second place, and especially in the latter half of the spring term. It is to be hoped that a fresh enthusiasm will take hold of us next Sep-tember and that then our presidents will not be required to hunt around over the campus and through the buildings to find a quorum. PHILO. The society has made an addition to its library in the shape of a book screen—a very necessary and handsome improvement. The new officers who have been elected to serve next year, are the following : President, C. H. Tilp ; Vice President, S. M. Herman ; Recording Secretary, I. Z. Im-ler ; Corresponding Secretary, J.
