8 ideas
9390 | Logic guides thinking, but it isn't a substitute for it [Rumfitt] |
Full Idea: Logic is part of a normative theory of thinking, not a substitute for thinking. | |
From: Ian Rumfitt (The Logic of Boundaryless Concepts [2007], p.13) | |
A reaction: There is some sort of logicians' dream, going back to Leibniz, of a reasoning engine, which accepts propositions and outputs inferences. I agree with this idea. People who excel at logic are often, it seems to me, modest at philosophy. |
21982 | I only wish I had such eyes as to see Nobody! It's as much as I can do to see real people. [Carroll,L] |
Full Idea: "I see nobody on the road," said Alice. - "I only wish I had such eyes," the King remarked. ..."To be able to see Nobody! ...Why, it's as much as I can do to see real people." | |
From: Lewis Carroll (C.Dodgson) (Through the Looking Glass [1886], p.189), quoted by A.W. Moore - The Evolution of Modern Metaphysics 07.7 | |
A reaction: [Moore quotes this, inevitably, in a chapter on Hegel] This may be a better candidate for the birth of philosophy of language than Frege's Groundwork. |
9389 | Vague membership of sets is possible if the set is defined by its concept, not its members [Rumfitt] |
Full Idea: Vagueness in respect of membership is consistency with determinacy of the set's identity, so long as a set's identity is taken to consist, not in its having such-and-such members, but in its being the extension of a concept. | |
From: Ian Rumfitt (The Logic of Boundaryless Concepts [2007], p.5) | |
A reaction: I find this view of sets much more appealing than the one that identifies a set with its members. The empty set is less of a problem, as well as non-existents. Logicians prefer the extensional view because it is tidy. |
23857 | People in power always try to increase their power [Weil] |
Full Idea: Every human group that exercises power does so …in such a way as to increase that power. | |
From: Simone Weil (Prospects: Proletarian Revolution? [1933], p.15) | |
A reaction: Not so true in smaller institutions, but at the centre of power you can control how power is distributed, so the temptation is too much. |
23856 | Spontaneous movements are powerless against organised repression [Weil] |
Full Idea: A spontaneous movement is fundamentally impotent when it comes to fighting against organised forces of repression. | |
From: Simone Weil (Prospects: Proletarian Revolution? [1933], p.2) | |
A reaction: Her example is the Paris Commune of 1870. Hence revolution requires prior penetration of the corridors of power. Hence the phenomenon of 'entryism' of more radical people into reformist parties. |
23859 | True democracy is the subordination of society to the individual [Weil] |
Full Idea: In the subordination of society to the individual lies the definition of true democracy, and that of socialism as well. | |
From: Simone Weil (Prospects: Proletarian Revolution? [1933], p.19) | |
A reaction: This is the simplest definition of the liberal view. The big difference is whether this subordination is the starting point of political thinking, or the end result at which it aims. |
23858 | War is perpetuated by its continual preparations [Weil] |
Full Idea: War perpetuates itself under the form of preparation for war. | |
From: Simone Weil (Prospects: Proletarian Revolution? [1933], p.16) | |
A reaction: There are periods when military preparations are scaled down, but a reason is always found to scale them back up again. |
23860 | Even if a drowning man is doomed, he should keep swimming to the last [Weil] |
Full Idea: A man who is thrown overboard in the middle of the ocean ought not to let himself drown, even though there is very litte chance of his reaching safety, but to go on swimming till exhausted. | |
From: Simone Weil (Prospects: Proletarian Revolution? [1933], p.21) | |
A reaction: You might survive a little longer if you don't exhaust yourself! Not clear where her authority for 'ought' comes from, but it expresses an interesting attitude. |
