  But even if they withdraw and thus exist apart from the particulars, their individuality seems to be determined by the company they keep, e.g., Socrates, or this bit of snow. ‘Belonging-to-Socrates’ is a relational property and seems to require that there be something, namely Socrates, to which the form-copy can belong. However, if form-copies are thus dependent on particulars, there is a problem with respect to the nature of particulars lurking in the Phaedo. For it seems that particulars have all of their properties in virtue of participating in the relevant Forms. Particulars, then, are ultimately to be identified in terms of the properties they have, namely their form-copies. But if these form-copies, in turn, are themselves individuated by the particulars whose form-copies they are, we are confronted with a circle.
