Reprint of the original Latin text Tentamina semiologica, sive quaedam generalem theoriam signorum spectantia (1789), edited, translated and with an Introduction by Robert E. Innis The 33 sections of this classic text by Hoffbauer have a twofold focus: a descriptive inventory of signs, and a comparison of the expressive and cognitive powers of different sign systems. Using his sign typology as a point of departure, Hoffbauer inquires into the elements of matter and form both necessary and adequate to arrive at a definition of the sign. His purpose in doing so is to present his own version of a general sign theory after pointing out significant errors and weaknesses in the characteristicae universalis of Leibniz, Becher, Toennis, Kalmar, etc. Against the background of criticism of the contemporary deductive sign theories of Lambert, Baumgarten, Mendelssohn, Daries, Wilkins, Kircher and others, Hoffbauer's general semiology gives shape to an outline of a deductive-hypothetical theory of signs. In this historical perspective, Hoffbauer's semiology is of outstanding importance and provides the opportunity to think through once again central and permanent problems of the general science of signs.

In the mid- to late-1930s, while he was a student at the Gregorian University in Rome, Bernard Lonergan wrote a series of eight essays on the philosophy and theology of history. These essays foreshadow a number of the major themes in his life's work. The significance of these essays is enormous, not only for an understanding of the later trajectory of Lonergan's own work but also for the development of a contemporary systematic theology. In an important entry from 1965 in his archival papers, Lonergan wrote that the "mediated object" of systematics is Geschichte or the history that is lived and written about. In the same entry, he stated that the "doctrines" that this systematic theology would attempt to understand are focused on "redemption." The seeds of such a theology are planted in the current volume, where the formulae that are so pronounced in his later work first appear. Students of Lonergan's work will find their understanding of his philosophy profoundly affected by the essays in this volume
