Single Idea 4031

[filed under theme 8. Modes of Existence / E. Nominalism / 3. Predicate Nominalism ]

Full Idea

I suggest that we reject the notion that just because the predicate 'red' applies to an open class of particulars, therefore there must be a property, redness.

Clarification

Predicates are part of language, properties part of reality

Gist of Idea

It doesn't follow that because there is a predicate there must therefore exist a property

A Reaction

At last someone sensible (an Australian) rebuts that absurd idea that our ontology is entirely a feature of our language


The 7 ideas from 'A Theory of Universals'

If what is actual might have been impossible, we need S4 modal logic [Armstrong, by Lewis]
Properties are universals, which are always instantiated [Armstrong, by Heil]
Even if all properties are categorical, they may be denoted by dispositional predicates [Armstrong, by Bird]
Universals explain resemblance and causal power [Armstrong, by Oliver]
A thing's self-identity can't be a universal, since we can know it a priori [Armstrong, by Oliver]
It doesn't follow that because there is a predicate there must therefore exist a property [Armstrong]
The type-token distinction is the universal-particular distinction [Armstrong, by Hodes]
