5 ideas
7458 | The reliability of witnesses depends on whether they benefit from their observations [Laplace, by Hacking] |
Full Idea: The credibility of a witness is in part a function of the story being reported. When the story claims to have infinite value, the temptation to lie for personal benefit is asymptotically infinite. | |
From: report of Pierre Simon de Laplace (Philosophical Essay on Probability [1820], Ch.XI) by Ian Hacking - The Emergence of Probability Ch.8 | |
A reaction: Laplace seems to especially have reports of miracles in mind. This observation certainly dashes any dreams one might have of producing a statistical measure of the reliability of testimony. |
21507 | Scientific explanation aims at a unifying account of underlying structures and processes [Hempel] |
Full Idea: What theoretical scientific explanation aims at is an objective kind of insight that is achieved by a systematic unification, by exhibiting the phenomena as manifestations of common underlying structures and processes that conform to testable principles. | |
From: Carl Hempel (Philosophy of Natural Science [1967], p.83), quoted by Laurence Bonjour - The Structure of Empirical Knowledge 5.3 | |
A reaction: This is a pretty good statement of scientific essentialism, and structures and processes are what I take Aristotle to have had in mind when he sought 'what it is to be that thing'. Structures and processes give stability and powers. |
18088 | Intentionality is the mark of dispositions, not of the mental [Place] |
Full Idea: My thesis is that intentionality is the mark, not of the mental, but of the dispositional. | |
From: Ullin T. Place (Intentionality and the Physical: reply to Mumford [1999], 1) | |
A reaction: An idea with few friends, but I really like it, because it offers the prospect of a unified account of physical nature and the mind/brain. It seems reasonable to say my mind is essentially a bunch of dispositions. Mind is representations + dispositions. |
3441 | If a supreme intellect knew all atoms and movements, it could know all of the past and the future [Laplace] |
Full Idea: An intelligence knowing at an instant the whole universe could know the movement of the largest bodies and atoms in one formula, provided his intellect were powerful enough to subject all data to analysis. Past and future would be present to his eyes. | |
From: Pierre Simon de Laplace (Philosophical Essay on Probability [1820]), quoted by Mark Thornton - Do we have free will? p.70 |
18089 | Dispositions are not general laws, but laws of the natures of individual entities [Place] |
Full Idea: Dispositions are the substantive laws, not, as for Armstrong, of nature in general, but of the nature of individual entities whose dispositional properties they are. | |
From: Ullin T. Place (Intentionality and the Physical: reply to Mumford [1999], 6) | |
A reaction: [He notes that Nancy Cartwright 1989 agrees with him] I like this a lot. I tend to denegrate 'laws', because of their dubious ontological status, but this restores laws to the picture, in the place where they belong, in the stuff of the world. |
