The longevity of Aristotelian natural science consists not so much in the fact that Aristotle’s solutions to puzzles were accepted by generations of philosophers, but by the fact that the presuppositions that made these puzzles look puzzling were. In what follows I consider some Neoplatonic responses to two puzzles that Aristotle poses in De Caelo Book 2, Chapter 12. Both Proclus and Simplicius rejected Aristotle’s solutions to the puzzles he posed. In one case, but not in the other, they also reassessed the relative importance of the presuppositions that created the puzzle.

In the present volume Proclus describes the 'creation' of the soul that animates the entire universe. This is not a literal creation, for Proclus argues that Plato means only to convey the eternal dependence of the World Soul upon higher causes. In his exegesis of Plato's text, Proclus addresses a range of issues in Pythagorean harmonic theory, as well as questions about the way in which the World Soul knows both forms and the visible reality that comprises its body. This part of Proclus' Commentary is particularly responsive to the interpretive tradition that precedes it. As a result, this volume is especially significant for the study of the Platonic tradition from the earliest commentators onwards.

It is an axiom of late neoplatonic metaphysics that all things are in all, but in each in an appropriate manner (ὀικείως, ET 103). These manners or modes of being are indicated by adverbial forms such as παραδειματικῶς or εἰκονικῶς. Thus, for example, the Forms are in the World Soul in the mode of images, while the objects in the sensible realm below Soul are in it in the manner of paradigms (in Tim. II 150.27). Among the many modes of being distinguished by Proclus we find existence ὁλικῶς and μερικῶς – in the manner of a whole and in the manner of a part. This paper investigates the nature and significance of these mereological modes of being.

This essay argues the Stoics are rightly regarded as pantheists. Their view differs from many forms of pantheism by accepting the notion of a personal god who exercises divine providence. Moreover, Stoic pantheism is utterly inimical to a deep ecology ethic. I argue that these features are nonetheless consistent with the claim that they are pantheists. The essay also considers the arguments offered by the Stoics. They thought that their pantheistic conclusion was an extension of the best science of their day. Some of their most interesting arguments are thusa posteriori
