8 ideas

1. Philosophy / F. Analytic Philosophy / 4. Conceptual Analysis
To explain a concept, we need its purpose, not just its rules of usage [Dummett]
     Full Idea: We cannot in general suppose that we give a proper account of a concept by describing those circumstance in which we do, and those in which we do not, make use of the relevant word. We explain the point of the concept, what we use the word for.
     From: Michael Dummett (Truth [1959], p.231)
     A reaction: Well said. I am beginning to develop a campaign to make sure that analytical philosophy focuses on understanding concepts (in a full 'logos' sort of way), and doesn't just settle for logical form or definition or rules of usage.
3. Truth / A. Truth Problems / 1. Truth
It is part of the concept of truth that we aim at making true statements [Dummett]
     Full Idea: It is part of the concept of truth that we aim at making true statements.
     From: Michael Dummett (Truth [1959], p.231)
     A reaction: This strikes me as a rather contentious but very interesting claim. An even stronger claim might be that its value (its normative force) is ALL that the concept of truth contributes to speech, other aspects being analysed into something else.
3. Truth / A. Truth Problems / 2. Defining Truth
We must be able to specify truths in a precise language, like winning moves in a game [Dummett]
     Full Idea: For a particular bounded language, if it is free of ambiguity and inconsistency, it must be possible to characterize the true sentences of the language; somewhat as, for a given game, we can say which moves are winning moves.
     From: Michael Dummett (Truth [1959], p.237)
     A reaction: The background of this sounds rather like Tarski, with truth just being a baton passed from one part of the language to another, though Dummett adds the very un-Tarskian notion that truth has a value.
3. Truth / F. Semantic Truth / 2. Semantic Truth
Tarski's truth is like rules for winning games, without saying what 'winning' means [Dummett, by Davidson]
     Full Idea: Tarski's definition of truth is like giving a definition of what it is to win in various games, without giving a hint as to what winning is (e.g. that it is what one tries to do when playing).
     From: report of Michael Dummett (Truth [1959]) by Donald Davidson - Truth and Predication 7
     A reaction: This led Dummett to his 'normative' account of truth. Formally, the fact that speakers usually aim at truth seems irrelevant, but in life you certainly wouldn't have grasped truth if you thought falsehood was just as satisfactory. The world is involved.
6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / g. Applying mathematics
At one level maths and nature are very similar, suggesting some deeper origin [Wolfram]
     Full Idea: At some rather abstract level one can immediately recognise one basic similarity between nature and mathematics ...this suggests that the overall similarity between mathematics and nature must have a deeper origin.
     From: Stephen Wolfram (A New Kind of Science [2002], p.772), quoted by Peter Watson - Convergence 17 'Philosophy'
     A reaction: Personally I think mathematics has been derived by abstracting from the patterns in nature, and then further extrapolating from those abstractions. So the puzzle in nature is not the correspondence with mathematics, but the patterns.
12. Knowledge Sources / B. Perception / 6. Inference in Perception
Broad rejects the inferential component of the representative theory [Broad, by Maund]
     Full Idea: Broad, one of the most important modern defenders of the representative theory of perception, explicitly rejects the inferential component of the theory.
     From: report of C.D. Broad (Mind and Its Place in Nature [1925]) by Barry Maund - Perception Ch.1
     A reaction: Since the supposed inferences happen much too quickly to be conscious, it is hard to see how we could distinguish an inference from an interpretation mechanism. Personally I interpret things long before the question of truth arises.
18. Thought / E. Abstraction / 1. Abstract Thought
You can't infer a dog's abstract concepts from its behaviour [Dummett]
     Full Idea: One could train a dog to bark only when a bell rang and a light shone without presupposing that it possessed the concept of conjunction.
     From: Michael Dummett (Truth [1959], p.235)
27. Natural Reality / C. Space / 4. Substantival Space
Space and its contents seem to be one stuff - so space is the only existing thing [Wolfram]
     Full Idea: It seems plausible that both space and its contents should somehow be made of the same stuff - so that in a sense space becomes the only thing in the universe.
     From: Stephen Wolfram (A New Kind of Science [2002], p.474), quoted by Peter Watson - Convergence 17 'Philosophy'
     A reaction: I presume the concept of a 'field' is what makes this idea possible.
