Single Idea 15849

[filed under theme 9. Objects / C. Structure of Objects / 8. Parts of Objects / a. Parts of objects ]

Full Idea

In 'Parmenides' it is argued that a part cannot be part of a many, but must be part of something one.

Gist of Idea

Plato says only a one has parts, and a many does not

Source

report of Plato (Parmenides [c.364 BCE], 157c) by Verity Harte - Plato on Parts and Wholes 3.2

Book Ref

Harte,Verity: 'Plato on Parts and Wholes' [OUP 2002], p.123

A Reaction

This looks like the right way to go with the term 'part'. We presuppose a unity before we even talk of its parts, so we can't get into contradictions and paradoxes about their relationships.
