Single Idea 8458

[filed under theme 7. Existence / E. Categories / 3. Proposed Categories ]

Full Idea

Modest ontologies are Nominalism (Goodman), admitting only concrete individuals; and Extensionalism (Quine/Davidson) which admits individuals and sets; but Intensionalists (Frege/Carnap/Church/Marcus/Kripke) may have propositions, properties, concepts.

Gist of Idea

Just individuals in Nominalism; add sets for Extensionalism; add properties, concepts etc for Intensionalism

A Reaction

I don't like sets, because of Idea 7035. Even the ontology of individuals could collapse dramatically (see the ideas of Merricks, e.g. 6124). The intensional items may be real enough, but needn't have a place at the ontological high table.
