7083 | Highest reason is aesthetic, and truth and good are subordinate to beauty [Hegel] |
Full Idea: I am now convinced that the highest act of reason, which embraces all ideas, is an aesthetic act, and that truth and goodness are brothers only in beauty. | |
From: Georg W.F.Hegel (Oldest System Prog. of German Idealism [1796]), quoted by Simon Critchley - Continental Philosophy - V. Short Intro Append | |
A reaction: This seems to be the distinctive value framework of the romantic movement and the nineteenth century, where art is destined to replace religion. However, Plato in the Symposium is an interesting ally. Aim for beauty, and the rest follows? |
12899 | The timid student has knowledge without belief, lacking confidence in their correct answer [Lewis] |
Full Idea: I allow knowledge without belief, as in the case of the timid student who knows the answer but has no confidence that he has it right, and so does not believe what he knows. | |
From: David Lewis (Elusive Knowledge [1996], p.429) | |
A reaction: [He cites Woozley 1953 for the timid student] I don't accept this example (since my views on knowledge are rather traditional, I find). Why would the student give that answer if they didn't believe it? Sustained timid correctness never happens. |
12897 | To say S knows P, but cannot eliminate not-P, sounds like a contradiction [Lewis] |
Full Idea: If you claim that S knows that P, and yet grant that S cannot eliminate a certain possibility of not-P, it certainly seems as if you have granted that S does not after all know that P. To speak of fallible knowledge just sounds contradictory. | |
From: David Lewis (Elusive Knowledge [1996], p.419) | |
A reaction: Starting from this point, fallibilism seems to be a rather bold move. The only sensible response seems to be to relax the requirement that not-P must be eliminable. Best: in one epistemic context P, in another not-P. |
12898 | Justification is neither sufficient nor necessary for knowledge [Lewis] |
Full Idea: I don't agree that the mark of knowledge is justification, first because justification isn't sufficient - your true opinion that you will lose the lottery isn't knowledge, whatever the odds; and also not necessary - for what supports perception or memory? | |
From: David Lewis (Elusive Knowledge [1996]) | |
A reaction: I don't think I agree. The point about the lottery is that an overwhelming reason will never get you to knowing that you won't win. But good reasons are coherent, not statistical. If perceptions are dubious, justification must be available. |
12895 | Knowing is context-sensitive because the domain of quantification varies [Lewis, by Cohen,S] |
Full Idea: The context-sensitivity of 'knows' is a function of contextual restrictions on the domain of quantification. | |
From: report of David Lewis (Elusive Knowledge [1996]) by Stewart Cohen - Contextualism Defended p.68 | |
A reaction: I think the shifting 'domain of quantification' is one of the most interesting features of ordinary talk. Or, more plainly. 'what are you actually talking about?' is the key question in any fruitful dialogue. Sophisticated speakers tacitly shift domain. |
19562 | We have knowledge if alternatives are eliminated, but appropriate alternatives depend on context [Lewis, by Cohen,S] |
Full Idea: S knows P if S's evidence eliminates every alternative. But the nature of the alternatives depends on context. So for Lewis, the context sensitivity of 'knows' is a function of contextual restrictions ln the domain of quantification. | |
From: report of David Lewis (Elusive Knowledge [1996]) by Stewart Cohen - Contextualism Defended (and reply) 1 | |
A reaction: A typical modern attempt to 'regiment' a loose term like 'context'. That said, I like the idea. I'm struck by how the domain varies during a conversation (as in 'what we are talking about'). Domains standardly contain 'objects', though. |
8693 | An 'abstraction principle' says two things are identical if they are 'equivalent' in some respect [Boolos] |
Full Idea: Hume's Principle has a structure Boolos calls an 'abstraction principle'. Within the scope of two universal quantifiers, a biconditional connects an identity between two things and an equivalence relation. It says we don't care about other differences. | |
From: George Boolos (Is Hume's Principle analytic? [1997]), quoted by Michèle Friend - Introducing the Philosophy of Mathematics 3.7 | |
A reaction: This seems to be the traditional principle of abstraction by ignoring some properties, but dressed up in the clothes of formal logic. Frege tries to eliminate psychology, but Boolos implies that what we 'care about' is relevant. |
