Single Idea 12577
[filed under theme 18. Thought / D. Concepts / 3. Ontology of Concepts / b. Concepts as abilities
]
Full Idea
Possession of any concept requires the capacity to make judgements whose content contain it.
Gist of Idea
Possessing a concept is being able to make judgements which use it
Source
Christopher Peacocke (A Study of Concepts [1992], 2.1)
Book Ref
Peacocke,Christopher: 'A Study of Concepts' [MIT 1999], p.44
A Reaction
Idea 12575 suggested that concept possession was an ability just to think about the concept. Why add that one must actually be able to make a judgement? Presumably to get truth in there somewhere. I may only speculate and fantasise, rather than judge.
