Full Idea

Pure, extreme nominalism sees all classification as the product of arbitrary convention.

Gist of Idea

Extreme nominalists say all classification is arbitrary convention

Source

Book Ref

A Reaction

I'm not sure what the word 'arbitrary' is doing there. Nominalists are not daft, and if they can classify any way they like, they are not likely to choose an 'arbitrary' system. Pragmatism tells the right story here.
