12312 | The real essence of a thing is its powers, or 'dispositional properties' [Copi] |
Full Idea: With respect to scientific usage, we can say that the real essence of a thing will consist very largely of powers or, in modern terms, dispositional properties. | |
From: Irving M. Copi (Essence and Accident [1954], p.718) | |
A reaction: Once again, Copi is a hero. I personally love the word 'powers' in metaphysics (and dislike the word 'properties', which is lost in a fog of confusion). See Molnar on 'powers' and Mumford on 'dispositions'. |
10789 | Nominalists say predication is relations between individuals, or deny that it refers [Marcus (Barcan)] |
Full Idea: Nominalists have the major task of explaining how predicates work. They usually construct it as a relation between individuals, or deny the referential function of predicates. | |
From: Ruth Barcan Marcus (Nominalism and Substitutional Quantifiers [1978], p.163) |
