Single Idea 8574

[catalogued under 8. Modes of Existence / E. Nominalism / 5. Class Nominalism]

Full Idea

Moderate Class Nominalism and Resemblance Nominalism (in its present form) seem to me to be a single theory presented in different styles.

Gist of Idea

Class Nominalism and Resemblance Nominalism are pretty much the same


David Lewis (New work for a theory of universals [1983], 'Un and Prop' n9)

Book Reference

'Properties', ed/tr. Mellor,D.H. /Oliver,A [OUP 1997], p.194

A Reaction

Lewis has earlier endorsed a cautious form of Class Nominalism (Idea 8570). Which comes first, having a resemblance, or being in a class? Quine seems to make resemblance basic (Idea 8486), but Lewis seems to make the class basic (Idea 8572).
