[catalogued under 18. Thought / E. Abstraction / 8. Abstractionism Critique]

Full Idea

The phrase 'abstracted from' does not refer to the mental process of abstraction by disregarding features of concrete objects, in which many nineteenth century thinkers believed; it is a logical (not mental) process of concept-formation.

Gist of Idea

To 'abstract from' is a logical process, as opposed to the old mental view

A Reaction

I take Frege's attack on 'psychologism' to be what dismissed the old view (Idea 5816). Could one not achieve the same story by negating properties in quantified logical expressions, instead of in the mind?
