Call of the nature. ; Llamado de la naturaleza
This paper aims to elaborate upon Pope Benedict's speech to the Bundestag in September 2011, just as he Himself suggests doing. The core of the discourse is the foundation of Law or the fundamental issue of its philosophy: Justice (which is the response from iusnaturalism to the question about such principle). With Kelsen, what is and what ought to be were set apart and that had an adverse effect on their essence. On the contrary, Benedict XVI wants to return to the ancient and perennial notion of justice, the foundation of Law that understood the just thing as a trinomial composed of nature (what is), reason (what ought to be), and Spiritus Creator (support of reason and nature) and made justice more comprehensible. This is the starting point from which this paper intends to comment on in order to facilitate the understanding of Benedict XVI's ideas, basing His thoughts on the book by Leonardo Boff La opción tierra (Earth option). From our point of view this book approximates what is to what ought to be and from Boff's ecologist view poses some questions in the human level, particularly in the field of Law ; Se busca desarrollar el discurso del papa Benedicto XVI al Bundestag en septiembre de 2011, talcomo su autor invita a hacerlo. El centro del discurso es el fundamento del Derecho o asuntobásico de su filosofía: la justicia (respuesta iusnaturalista a la pregunta sobre tal fundamento).Con Kelsen, el Derecho separó el ser del deber ser, afectando de manera negativa su esencia. Benedicto XVI, por el contrario, quiere volver al ancestral y perenne concepto de justicia que cimenta el Derecho, que veía lo justo como un trinomio compuesto de naturaleza (ser), razón (deber ser) y Spiritus Creator (sustento de razón y naturaleza), que hacía de la justicia algo más comprensible. Desde ahí se pretende hacer algunas glosas que faciliten la comprensión del pensamiento de Benedicto XVI, apoyando el pensamiento papal en el escrito de Leonardo Bofftitulado La opción Tierra, libro que, a mi juicio, acerca el ser al deber ser y sugiere desde esapostura ecologicista boffiana algunos interrogantes en el plano humano, más concretamenteen el terreno del Derecho.
