Triangles, Tropes, and τὰ τοιαῦτα: A Trope Theory in Plato’s Timaeus

A standard interpretation of Plato’s metaphysics holds that sensible particulars are copies of Forms. Such particulars are fairly independent, like Aristotelian substances. I argue that this is incorrect: Platonic particulars are not Form images but aggregates of Form images, which are property-instances (tropes). Timaeus 49e-50a focuses on “this-suches” (toiauta) and even goes so far as to claim that they compose other things. I argue that Form images are this-suches, which are tropes. I also examine the geometrical account, showing that the geometrical constituents of the elements are also Form images. Thus everything in the sensible world is composed of tropes
