Single Idea 18372

[filed under theme 8. Modes of Existence / B. Properties / 2. Need for Properties ]

Full Idea

The 'thing itself' seems not be a minimal truthmaker for the thing having its particular mass. ...The thing has a great many other properties. ...It seems entirely reasonable to postulate that the object has properties that are objectively there.

Gist of Idea

We need properties, as minimal truthmakers for the truths about objects

A Reaction

This is Armstrong using the truthmaker principle to argue for the existence of properties (as instantiated universals). I like truthmakers, but truths do not have enough precision in their parts for us to read off reality from them.

To be a 'property' is to suit a theoretical role [Lewis]
There are just as many properties as the laws require [Oliver]
We need properties to explain how the world works [Heil]
We accept properties because of type/tokens, reference, and quantification [Edwards]
