7 ideas
23877 | 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! |
16974 | The nature of each logical concept is given by a collection of inference rules [Correia] |
Full Idea: The view presented here presupposes that each logical concept is associated with some fixed and well defined collection of rules of inference which characterize its basic logical nature. | |
From: Fabrice Correia (On the Reduction of Necessity to Essence [2012], 4) | |
A reaction: [He gives Fine's 'Senses of Essences' 57-8 as a source] He seems to have in mind natural deduction, where the rules are for the introduction and elimination of the concepts. |
16973 | Explain logical necessity by logical consequence, or the other way around? [Correia] |
Full Idea: One view is that logical consequence is to be understood in terms of logical necessity (some proposition holds necessarily, if some group of other propositions holds). Alternatively, logical necessity is a logical consequence of the empty set. | |
From: Fabrice Correia (On the Reduction of Necessity to Essence [2012], 3) | |
A reaction: I think my Finean preference is for all necessities to have a 'necessitator', so logical necessity results from logic in some way, perhaps from logical consequence, or from the essences of the connectives and operators. |
23878 | 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. |
468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
23879 | 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. |
23880 | 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'. |
