Abstract

In what follows I propose to consider the relevance of Plato's early claim that his Forms are explanatory to the structure of, and several of the main arguments of, the Parmenides. The first section of the paper looks into some implications of separate existence, exploring connections between the criticism of separation and the conception of Forms as explanatory principles. I focus attention on what the Forms do not explain, and suggest that the burden of much of Parmenides’ criticism centers on that question. Part two deals with Plato's evidently changing stance on the issue of explaining the Forms themselves. The third section takes up passages from the Parmenides in support of the view that Plato came to believe that his Forms stood in need of the same sort of explanation as he had originally thought was required for sensory particulars. The discussion is largely exploratory, and the connections adumbrated are intended as guidelines for further investigation.
