19086 | Does the pragmatic theory of meaning support objective truth, or make it impossible? [Macbeth] |
Full Idea: Peirce and Sellars takes Peirce's conception of meaning, on which pragmatism is founded, to support an adequate account of objective truth; James, Dewey and Rorty say it forecloses all possibility of such an account. | |
From: Danielle Macbeth (Pragmatism and Objective Truth [2007], p.169) | |
A reaction: Ah. Very helpful. I thought there was a pragmatic theory of truth, then began to think that it was just a denial of truth. I've long suspected that Peirce is wonderful, and James is not very good (on this topic). |
10245 | One geometry cannot be more true than another [Poincaré] |
Full Idea: One geometry cannot be more true than another; it can only be more convenient. | |
From: Henri Poincaré (Science and Method [1908], p.65), quoted by Stewart Shapiro - Philosophy of Mathematics | |
A reaction: This is the culminating view after new geometries were developed by tinkering with Euclid's parallels postulate. |
19093 | Greek mathematics is wholly sensory, where ours is wholly inferential [Macbeth] |
Full Idea: Ancient mathematical concepts were essentially sensory; they were not mathematical in our sense - that is, wholly constituted by their inferential potential. | |
From: Danielle Macbeth (Pragmatism and Objective Truth [2007], p.187) | |
A reaction: The latter view is Frege's, though I suppose it had been emerging for a couple of centuries before him. I like the Greek approach, and would love to see that reunited with the supposedly quite different modern view. (Keith Hossack is attempting it). |
19091 | Seeing reality mathematically makes it an object of thought, not of experience [Macbeth] |
Full Idea: As mathematically understood, the world is not an object of experience but instead an object of thought. | |
From: Danielle Macbeth (Pragmatism and Objective Truth [2007], p.183) | |
A reaction: Since I am keen on citing biology to show that science does not have to be mathematical, this nicely shows that there is something wrong with a science which places a large gap between itself and the world. |
16362 | An identity statement aims at getting the hearer to merge two mental files [Lockwood] |
Full Idea: The purpose of an identity statement is to get the hearer to merge these files or bodies of information into one. | |
From: Michael Lockwood (Identity and Reference [1971], p.209), quoted by François Recanati - Mental Files 4.1 | |
A reaction: Lockwood is a pioneer, in seeing 'Hesperus is Phosphorus' and 'Scott is the author of 'Waverley'' in terms of how the mind works. Mental files seem to me to explain a huge amount. Recanati proposes 'linking' rather than 'merging'. |
19088 | For pragmatists a concept means its consequences [Macbeth] |
Full Idea: In the pragmatist view, the meaning of a concept is exhausted by its consequences. | |
From: Danielle Macbeth (Pragmatism and Objective Truth [2007], p.173) | |
A reaction: I'm unclear why the concept of a volcanic eruption only concerns its dire consequences, and is supposed to contain nothing of its causes. Pragmatists seem to be all future, and no past. Very American. |
