5 ideas
| 9355 | One sort of circularity presupposes a premise, the other presupposes a rule being used [Braithwaite, by Devitt] |
| Full Idea: An argument is 'premise-circular' if it aims to establish a conclusion that is assumed as a premise of that very argument. An argument is 'rule-circular' if it aims to establish a conclusion that asserts the goodness of the rule used in that argument. | |
| From: report of R.B. Braithwaite (Scientific Explanation [1953], p.274-8) by Michael Devitt - There is no a Priori §2 | |
| A reaction: Rule circularity is the sort of thing Quine is always objecting to, but such circularities may be unavoidable, and even totally benign. All the good things in life form a mutually supporting team. |
| 18902 | Correspondence theories can't tell you what truths correspond to [Davidson] |
| Full Idea: The real objection to correspondence theories is that such theories fail to provide entities to which truth vehicles (as statements, sentence, or utterances) can be said to correspond. | |
| From: Donald Davidson (The Structure and Content of Truth [1990], p.304), quoted by Fred Sommers - Intellectual Autobiography Notes 23 | |
| A reaction: This is the remark which provoked Sommers to come out with Idea 18901, which strikes me as rather profound. |
| 16083 | Aristotelian matter seriously threatens the intrinsic unity and substantiality of its object [Gill,ML] |
| Full Idea: On the interpretation of Aristotelian matter that I shall propose, matter seriously threatens the intrinsic unity, and hence the substantiality, of the object to which it contributes. | |
| From: Mary Louise Gill (Aristotle on Substance [1989], Intro) | |
| A reaction: Presumably the thought is that if an object is form+matter (hylomorphism), then forms are essentially unified, but matter is essentially unified and sloppy. |
| 17006 | Prime matter has no place in Aristotle's theories, and passages claiming it are misread [Gill,ML] |
| Full Idea: I argue that prime matter has no place in Aristotle's elemental theory. ..References to prime matter are found in Aristotle's work because his theory was thought to need the doctrine. If I am right, these passages will all admit of another interpretation. | |
| From: Mary Louise Gill (Aristotle on Substance [1989], App) | |
| A reaction: If correct, this strikes me as important for the history of ideas, because scholastics got themselves in a right tangle over prime matter. See Pasnau on it. It pushed the 17th century into corpuscularianism. |
| 16093 | Prime matter is actually nothing and potentially everything (or potentially an element) [Gill,ML] |
| Full Idea: Prime matter is supposed to be actually nothing and potentially everything or, at any rate, potentially the simplest bodies - earth, water, air and fire. | |
| From: Mary Louise Gill (Aristotle on Substance [1989], Ch.1) | |
| A reaction: The view that the four elements turn out to be prime matter is distinctive of Gill's approach. Prime matter sounds like quark soup in the early universe. |
