This set of previously published essaysseveral of them now expanded and revisedoffers a sustained analysis of conceptual connections between (i) the metaphysics and epistemology of Parmenides and (ii) corresponding themes in the philosophies of other pre-Socratics. The book's central part explores how the early philosophers of Greece became progressively sensitized to the importance of such concepts as "form", "type", "structure", "arrangement". This developed in large measure because such concepts, importing as they do plurality and differentiation, are inherently problematic for Parmenides. The book's central part may thus be read as an account of the "discovery of Form" in early Greek philosophy.
