10993 | Ramsey's Test: believe the consequent if you believe the antecedent [Ramsey, by Read] |
Full Idea: Ramsey's Test for conditionals is that a conditional should be believed if a belief in its antecedent would commit one to believing its consequent. | |
From: report of Frank P. Ramsey (Law and Causality [1928]) by Stephen Read - Thinking About Logic Ch.3 | |
A reaction: A rather pragmatic approach to conditionals |
14279 | Asking 'If p, will q?' when p is uncertain, then first add p hypothetically to your knowledge [Ramsey] |
Full Idea: If two people are arguing 'If p, will q?' and are both in doubt as to p, they are adding p hypothetically to their stock of knowledge, and arguing on that basis about q; ...they are fixing their degrees of belief in q given p. | |
From: Frank P. Ramsey (Law and Causality [1928], B 155 n) | |
A reaction: This has become famous as the 'Ramsey Test'. Bennett emphasises that he is not saying that you should actually believe p - you are just trying it for size. The presupposition approach to conditionals seems attractive. Edgington likes 'degrees'. |
6894 | Mental terms can be replaced in a sentence by a variable and an existential quantifier [Ramsey] |
Full Idea: Ramsey Sentences are his technique for eliminating theoretical terms in science (and can be applied to mental terms, or to social rights); a term in a sentence is replaced by a variable and an existential quantifier. | |
From: Frank P. Ramsey (Law and Causality [1928]), quoted by Thomas Mautner - Penguin Dictionary of Philosophy p.469 | |
A reaction: The technique is used by functionalists and results in a sort of eliminativism. The intrinsic nature of mental states is eliminated, because everything worth saying can be expressed in terms of functional/causal role. Sounds wrong to me. |
6316 | We translate in a way that makes the largest possible number of statements true [Wilson,NL] |
Full Idea: We select as designatum that individual which will make the largest possible number of statements true. | |
From: N.L. Wilson (Substances without Substrata [1959]), quoted by Willard Quine - Word and Object II.§13 n | |
A reaction: From the Quine's reference, it sounds as if Wilson was the originator of the well-known principle of charity, later taken up by Davidson. If so, he should be famous, because it strikes me as a piece of fundamental and important wisdom. |
20767 | Culture is now dominated by boredom, so universal it is unnoticed [Heidegger, by Aho] |
Full Idea: Heidegger came to say that the cultural mood had changed from 'anxiety' to 'boredom'. The danger is that our boredom has become so ubiquitous and all-encompassing that it is now hidden. | |
From: report of Martin Heidegger (Contributions to Philosophy [1938]) by Kevin Aho - Existentialism: an introduction 9 'Conc' | |
A reaction: I'm not sure what the danger of boredom is if it is 'hidden'. It rather depends what else is hidden with it. |
9418 | All knowledge needs systematizing, and the axioms would be the laws of nature [Ramsey] |
Full Idea: Even if we knew everything, we should still want to systematize our knowledge as a deductive system, and the general axioms in that system would be the fundamental laws of nature. | |
From: Frank P. Ramsey (Law and Causality [1928], §A) | |
A reaction: This is the Mill-Ramsey-Lewis view. Cf. Idea 9420. |
9420 | Causal laws result from the simplest axioms of a complete deductive system [Ramsey] |
Full Idea: Causal laws are consequences of those propositions which we should take as axioms if we knew everything and organized it as simply as possible in a deductive system. | |
From: Frank P. Ramsey (Law and Causality [1928], §B) | |
A reaction: Cf. Idea 9418. |
