7 ideas

3. Truth / A. Truth Problems / 3. Value of Truth
Most people won't question an idea's truth if they depend on it [Weil]
     Full Idea: The majority of human beings do not question the truth of an idea without which they would literally be unable to live.
     From: Simone Weil (Is There a Marxist Doctrine? [1943], p.163)
     A reaction: I assume that this inability grows stronger with age, as the dependence on the idea runs deeper. Hence for most people the beliefs which sustain them have a higher value than truth. Obviously we should all make love of truth our guiding idea!
6. Mathematics / C. Sources of Mathematics / 4. Mathematical Empiricism / c. Against mathematical empiricism
The existence of an arbitrarily large number refutes the idea that numbers come from experience [Hilbert]
     Full Idea: The standpoint of pure experience seems to me to be refuted by the objection that the existence, possible or actual, of an arbitrarily large number can never be derived through experience, that is, through experiment.
     From: David Hilbert (On the Foundations of Logic and Arithmetic [1904], p.130)
     A reaction: Alternatively, empiricism refutes infinite numbers! No modern mathematician will accept that, but you wonder in what sense the proposed entities qualify as 'numbers'.
6. Mathematics / C. Sources of Mathematics / 6. Logicism / d. Logicism critique
Logic already contains some arithmetic, so the two must be developed together [Hilbert]
     Full Idea: In the traditional exposition of the laws of logic certain fundamental arithmetic notions are already used, for example in the notion of set, and to some extent also of number. Thus we turn in a circle, and a partly simultaneous development is required.
     From: David Hilbert (On the Foundations of Logic and Arithmetic [1904], p.131)
     A reaction: If the Axiom of Infinity is meant, it may be possible to purge the arithmetic from the logic. Then the challenge to derive arithmetic from it becomes rather tougher.
7. Existence / A. Nature of Existence / 3. Being / e. Being and nothing
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.
20. Action / B. Preliminaries of Action / 2. Willed Action / d. Weakness of will
Weakness of will is the inadequacy of the original impetus to carry through the action [Weil]
     Full Idea: It is naïve to be astonished when we do not stick to firm resolutions. Something stimulated the resolution, but that something was not powerful enough to bring us to the point of carrying it out. Making the resolution may even have exhausted the stimulus.
     From: Simone Weil (Is There a Marxist Doctrine? [1943], p.169)
     A reaction: Socrates says it is a change of belief. Aristotle says it is a desire overcoming a belief. Weil gives a third way: that it is a fading in the strength of the original belief/desire impetus.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / j. Ethics by convention
In a violent moral disagreement, it can't be that both sides are just following social morality [Weil]
     Full Idea: If two men are in violent disagreement about good and evil, it is hard to believe that both of them are blindly subject to the opinion of the society around them.
     From: Simone Weil (Is There a Marxist Doctrine? [1943], p.171)
     A reaction: What a beautifully simple observation. Simone would have become a major figure if she had lived longer. No philosopher has ever written better prose.
25. Social Practice / E. Policies / 1. War / b. Justice in war
When war was a profession, customary morality justified any act of war [Weil]
     Full Idea: At the time when war was a profession, fighting men had a morality whereby any act of war, in accordance with the customs of war, and contributing to victory, was legitimate and right.
     From: Simone Weil (Is There a Marxist Doctrine? [1943], p.173)
     A reaction: Note the caveat about 'customs', which were largely moral. See the discussion of killing the non-combatant prisoners in Shakespeare's 'Henry V'.
