8226 | A well-posed problem is a problem solved [Bergson, by Deleuze/Guattari] |
Full Idea: Bergson said that a well-posed problem was a problem solved | |
From: report of Henri Bergson (works [1910]) by G Deleuze / F Guattari - What is Philosophy? 1.3 | |
A reaction: This is fairly well in tune with the logical positivist style of philosophising, which tends to ask "what exactly is the question?" rather more than it asks "what is the answer?". I thoroughly approve of both of them (e.g. on free will). |
14296 | Dispositions are physical states of mechanism; when known, these replace the old disposition term [Quine] |
Full Idea: Each disposition, in my view, is a physical state or mechanism. ...In some cases nowadays we understand the physical details and set them forth explicitly in terms of the arrangement and interaction of small bodies. This replaces the old disposition. | |
From: Willard Quine (The Roots of Reference [1990], p.11), quoted by Stephen Mumford - Dispositions 01.3 | |
A reaction: A challenge to the dispositions and powers view of nature, one which rests on the 'categorical' structural properties, rather than the 'hypothetical' dispositions. But can we define a mechanism without mentioning its powers? |
2798 | Probability of H, given evidence E, is prob(H) x prob(E given H) / prob(E) [Horwich] |
Full Idea: Bayesianism says ideally rational people should have degrees of belief (not all-or-nothing beliefs), corresponding with probability theory. Probability of H, given evidence E, is prob(H) X prob(E given H) / prob(E). | |
From: Paul Horwich (Bayesianism [1992], p.41) |
2799 | Bayes' theorem explains why very surprising predictions have a higher value as evidence [Horwich] |
Full Idea: Bayesianism can explain the fact that in science surprising predictions have greater evidential value, as the equation produces a higher degree of confirmation. | |
