Michael Wedin argues against the prevailing notion that Aristotle's views on the nature of reality are fundamentally inconsistent. According to Wedin's new interpretation, the difference between the early theory of the Categories and the later theory of the Metaphysics reflects the fact that Aristotle is engaged in quite different projects in the two works--the earlier focusing on ontology, and the later on explanation.

Michael V. Wedin presents a rigorous reconstruction of the deductions in Parmenides' Way of Truth: the most important philosophical treatise before Plato and Aristotle. He answers criticisms which claim that Parmenides' arguments are shot through with logical fallacies, and argues against natural explanations of Parmenides in the Ionian tradition.
