Single Idea 8574
[filed under theme 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
Source
David Lewis (New work for a theory of universals [1983], 'Un and Prop' n9)
Book Ref
'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).
Related Ideas
Idea 8570
To have a property is to be a member of a class, usually a class of things [Lewis]
Idea 8486
Standards of similarity are innate, and the spacing of qualities such as colours can be mapped [Quine]
Idea 8572
Any class of things is a property, no matter how whimsical or irrelevant [Lewis]
