Heredera directa de la tradición griega, la filosofía helenística no desatendió el llamamiento de la naturaleza, de la φύσις. Una reflexión sobre ella, directa o indirecta, verbalizada o silenciosa, puede reconocerse prácticamente en cada escuela de este período de la historia de la filosofía. No puede decirse, pues, que la cuestión de la naturaleza, la pregunta filosófica por la realidad natural, fue eludida y desestimada durante el helenismo; sin embargo, tampoco puede afirmarse categóricamente la absoluta centralidad de dicha pregunta. La (...) verdadera relevancia de la naturaleza en la amplia gama de filosofías helenísticas se muestra de acuerdo con el sentido que adquiere este término en cada caso. Aunque no está exento de objeciones, hay cierto consenso en considerar que, debido a la situación histórica, lo realmente central en la filosofía helenística es la preocupación por los asuntos prácticos, por las consecuencias éticas del pensamiento o bien experimental, o bien especulativo, aquellas consecuencias que contribuyen a la imperturbabilidad del alma y procuran la felicidad. Atrás quedó el saber inútil —si en algún momento verdaderamente existió— de lo que se trata ahora es de orientar todo esfuerzo teórico, físico y metafísico, hacia la consecución de una vida buena.

The present paper focuses on some aspects of the Neoplatonist literary-metaphysical theory, which has clearly been expressed in the anony­mous Prolegomena to Plato’s philosophy and further confirmed in Proclus’ exegesis of the Timaeus. Thus, this contribution, examines and compares several passages from the Prolegomena and from Proclus’ Commentary on the Timaeus with a view to showing that it is legiti­mate to speak of a certain cosmogony of the Platonic dialogue that is analogous to that of the macrocosm. Moreover, the analogy (...) between macrocosm and microcosm makes it possible to further investigate the similarity between the λόγος-ζῷον of the Demiurge and that of Timaeus, on the one hand, and the reality which the λόγος expresses, on the other. This similarity turns out to be both structural/morphological and content-related/semantic. Thus, by combining the natural and theo­logical science, the analysis of the “generation” of the macrocosm and microcosm brings out the strongly analogical nature of Plato’s dialogues, which is particularly visible in the Timaeus.

From the first century BCE onwards, philosophers started to write commentaries on those Aristotle’s treatises that were meant for the internal use of his school. Plato’s works had been commented on already earlier, the first reported commentary originates in the 300s BCE. Commentaries are treatises that follow an object text in a more or less linear fashion. The format was not unknown before the first century BCE but new in extensive philosophical use. This review essay focuses on authors who commented (...) on Aristotle’s works. The commentaries emerged when Platonists and Aristotelians observed the need to teach the philosophy of these ancient masters to their students and to systematise their philosophy to respond to rival schools. In the late ancient schools, Plato and Aristotle were considered great thinkers, whose views needed to be studied carefully when considering any matter at hand. Many also argued that, despite the initial appearance to the contrary, there is no deep disagreement between Plato and Aristotle but, rather, a division of labour; Aristotle is dominant in natural philosophy and Plato in theology. However, this harmony thesis was not universally accepted. Despite their respect for Plato and Aristotle, the commentators were not mere followers of these authors. They developed, criticised and transformed the doctrines in significant ways, not only by suggesting different answers to the same questions but also by transforming the questions themselves.

In The First Principle, Jonathan Greig examines the philosophical theology of the two Neoplatonists, Proclus and Damascius (5th–6th centuries A.D.), on the One as the first cause. Both philosophers address a tension in the Neoplatonic tradition: namely that the One was seen as absolutely transcendent, yet it was also seen as intimately related to other things as the source of their unity and being. Proclus’ solution is to posit intermediate causes after the One, while Damascius posits a distinct principle, the (...) ‘Ineffable’, above the One. This book provides a new, thorough study of the theories of causation that lead each to their respective position and reveals crucial insights involved in a rigorous negative theology employed in metaphysics.

En este texto se explora la llamada teoría de las cinco sustancias que ha caracterizado la interpretación de la ontología ficiniana desde que Kristeller publicó su libro El pensamiento filosófico de Marsilio Ficino. Se busca cuestionar su pertinencia a partir de la exploración del primer capítulo del Libro I de la Teología Platónica con el fin de evidenciar que no es claro que las cinco hipóstasis o grados de lo real puedan ser identificadas con el término “sustancia” en el trabajo (...) de Ficino. A partir de la confrontación de algunos pasajes de su Comentario al Parménides se propone que es más adecuado calificar como “sustancia” a las tres primeras hipóstasis y que, por tanto, la interpretación tradicional de la ontología ficiniana no es exacta.

In his commentary on Euclid, Proclus says both that the first principle of geometry are self-evident and that they are hypotheses received from the single, highest, unhypothetical science, which is probably dialectic. The implication of this seems to be that a geometer both does and does not know geometrical truths. This dilemma only exists if we assume that Proclus follows Aristotle in his understanding of these terms. This paper shows that this is not the case, and explains what Proclus himself (...) means by definition, hypothesis, axiom, postulate, and the self-evident, and how geometry is a science that receives its principles from dialectic.
