Single Idea 4587

[catalogued under 8. Modes of Existence / B. Properties / 10. Properties as Predicates]

Full Idea

If P and Q are predicates denoting properties, we can construct a disjunctive predicate ('P or Q'). But it is not clear that this gives us any right whatever to suppose that 'P or Q' designates a property.

Gist of Idea

From the property predicates P and Q, we can get 'P or Q', but it doesn't have to designate another property

A Reaction

An important idea, needed to disentangle our ontology from our language, and realise that they are separate. Properties are natural; predicates are conventional.
