| 14283 | A conditional probability does not measure the probability of the truth of any proposition [Lewis, by Edgington] |
| Full Idea: Lewis was first to prove this remarkable result: there is no proposition A*B such that, in all probability distributions, p(A*B) = pA(B) [second A a subscript]. A conditional probability does not measure the probability of the truth of any proposition. | |
| From: report of David Lewis (Probabilities of Conditionals [1976]) by Dorothy Edgington - Conditionals (Stanf) 3.1 | |
| A reaction: The equation says the probability of the combination of A and B is not always the same as the probability of B given A. Bennett refers to this as 'The Equation' in the theory of conditionals. Edgington says a conditional is a supposition and a judgement. |
| 21513 | We can no more expect a precise definition of coherence than we can of the moral ideal [Ewing] |
| Full Idea: I think it is wrong to tie down the advocates of the coherence theory to a precise definition. ...It would be altogether unreasonable to demand that the moral ideal should be exhaustively defined, and the same may be true of the ideal of thought. | |
| From: A.C. Ewing (Idealism: a critical survey [1934], p.231), quoted by Erik J. Olsson - Against Coherence 7.6 | |
| A reaction: I strongly agree. It is not a council of despair. I think the criteria of coherence can be articulated quite well (e.g by Thagard), and the virtues of enquiry can also be quite well specified (e.g. by Zagzebski). Very dissimilar evidence must cohere. |
| 21497 | If undetailed, 'coherence' is just a vague words that covers all possible arguments [Ewing] |
| Full Idea: Without a detailed account, coherence is reduced to the mere muttering of the word 'coherence', which can be interpreted so as to cover all arguments, but only by making its meaning so wide as to rob it of almost all significance. | |
| From: A.C. Ewing (Idealism: a critical survey [1934], p.246), quoted by Erik J. Olsson - Against Coherence 2.2 | |
| A reaction: I'm a fan of coherence, but it is a placeholder, involving no intrinsic or detailed theory. I just think it points to the reality of how we make judgements, especially practical ones. We can categorise the inputs, and explain the required virtues. |
| 12156 | Aesthetics has risen and fallen with Romanticism [Scruton] |
| Full Idea: The rise and fall (as we presently perceive them) of aesthetics have been contemporaneous with the rise and fall of Romanticism. | |
| From: Roger Scruton (Recent Aesthetics in England and America [1980], p.3) | |
| A reaction: Maybe it started a little before Romanticism, as part of the Englightenment aim of being rational about everything, and maybe it survives Romanticism because we want to be scientific about everything. |
| 12158 | Aesthetic experience informs the world with the values of the observer [Scruton] |
| Full Idea: It is possible to conclude that aesthetic experience has a peculiar practical significance: it represents the world as informed by the values of the observer. | |
| From: Roger Scruton (Recent Aesthetics in England and America [1980], p.13) | |
| A reaction: An excellent remark. If you look at, or listen to, anything, you can make a conscious effort to drain away your personal values (objectivity; science?), or you can consciously flood them with values. But moral and aesthetic vision must differ... |
