Abstract

This study presents the way in which Proclus structures some aspects of his Epistemology on the basis of his metaphysical Ontology. All those that we discuss – relying on his comments on Parmenides (Εἰς τὸν Πλάτωνος Παρμενίδην) (816.11– 819.29) –, take into account the following: a) his theory on the universal Intellect and the individual intellects, b) his theory on the universal Soul and the individual souls, c) some approaches of his in Plato’s theory of Ideas. Combining the above, our purpose is also to show in what way some specific manifestations of the metaphysical world are connected with the natural world. The Neoplatonist philosopher explains the relevant theories by following a clearly defined method and that is why his analyses compose a cohesive system or a coherent Epistemology. He follows the principles that he has established on the basis of a clear ontological realism, which is based on his views about how the similarities and the differences between the two worlds appear. By elaborating these principles, we come to the conclusion that the methodological tools used by him are the principle of analogy, analytical thinking and hypothetical syllogisms.
