Single Idea 18995

[catalogued under 7. Existence / A. Nature of Existence / 6. Criterion for Existence]

Full Idea

Frege's theory treats existence as a property, not of things we call existent, but of concepts instantiated by those things. 'Biden exists' says our Biden-concept has instances. That is certainly not how it feels! We speak of the thing, not of concepts.

Clarification

'Biden' is an American politician

Gist of Idea

Frege mistakenly takes existence to be a property of concepts, instead of being about things

Source

report of Gottlob Frege (On Concept and Object [1892]) by Stephen Yablo - Aboutness 01.4

Book Reference

A Reaction

Yablo's point is that you must ask what the sentence is 'about', and then the truth will refer to those things. Frege gets into a tangle because he thinks remarks using concepts are about the concepts.
