Single Idea 21563

[catalogued under 4. Formal Logic / F. Set Theory ST / 5. Conceptions of Set / c. Logical sets]

Full Idea

The contention of the 'no classes' theory is that all significant propositions concerning classes can be regarded as propositions about all or some of their members.

Gist of Idea

The 'no classes' theory says the propositions just refer to the members


Bertrand Russell (On 'Insolubilia' and their solution [1906], p.200)

A Reaction

Apparently this theory has not found favour with later generations of theorists. I see it in terms of Russell trying to get ontology down to the minimum, in the spirit of Goodman and Quine.
