18. Thought / D. Concepts / 2. Origin of Concepts / b. Empirical concepts
Grounded concepts are trustworthy maps of the world [Jenkins]
     Full Idea: Grounded concepts are like trustworthy on-board maps of the independent world.
     From: Carrie Jenkins (Grounding Concepts [2008], Intro)
     A reaction: You'll probably need more than one concept for it to qualify as a 'map', but I like this idea a lot. The world, rather than we ourselves, creates our concepts. The opposite of the view of Geach in 'Mental Acts'.
The physical effect of world on brain explains the concepts we possess [Jenkins]
     Full Idea: I think the physical effects of the world on the brain explain our possessing the concepts we do.
     From: Carrie Jenkins (Grounding Concepts [2008], 8.2)
     A reaction: A nice slogan for a thought which strikes me as exactly right.
18. Thought / D. Concepts / 3. Ontology of Concepts / b. Concepts as abilities
Possessing a concept is knowing how to go on [Wittgenstein, by Peacocke]
     Full Idea: Wittgenstein implies that which concepts a thinker is capable of possessing depends on the ways in which he is capable of finding a natural way to go on.
     From: report of Ludwig Wittgenstein (Philosophical Investigations [1952]) by Christopher Peacocke - A Study of Concepts 1.2
     A reaction: This doesn't seem to amount to much. Presumably someone who failed to grasp a concept would demonstrate the fact by going on in a silly way, and whether or not it was silly might not be obvious. A genius may go on in a quirky way.
Concepts direct our interests and investigations, and express those interests [Wittgenstein]
     Full Idea: Concepts lead us to make investigations; are the expression of our interest, and direct our interest.
     From: Ludwig Wittgenstein (Philosophical Investigations [1952], §570)
     A reaction: This presumably points to the evolutionary origin of our concept-creating capacity, though I am not sure that it defines what a concept actually is.
Man learns the concept of the past by remembering [Wittgenstein]
     Full Idea: Man learns the concept of the past by remembering.
     From: Ludwig Wittgenstein (Philosophical Investigations [1952], II.13)
     A reaction: [quoted by Peacocke] Is it the case that we learn all of our concepts by doing? Obviously not, since we can be taught them. Could you have no long-term memories (head trauma), and be taught the concept of the past by someone else?
18. Thought / D. Concepts / 4. Structure of Concepts / h. Family resemblance
Various games have a 'family resemblance', as their similarities overlap and criss-cross [Wittgenstein]
     Full Idea: I shall say 'games' form a family, with a 'family resemblance', for the resemblances within a family - build, eyes, temperament etc. - overlap and criss-cross in the same way.
     From: Ludwig Wittgenstein (Philosophical Investigations [1952], §067)
     A reaction: A very helpful idea for the nominalist view of universals, particularly for showing how concepts shade off indeterminately at the edges.
