8 ideas
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. |
7435 | Dispositions are second-order properties, the property of having some property [Jackson/Pargetter/Prior, by Armstrong] |
Full Idea: It was proposed that dispositions are second-order properties of objects: the property of having some property. | |
From: report of Jackson/Pargetter/Prior (Three theses about dispositions [1982]) by David M. Armstrong - Pref to new 'Materialist Theory' p.xvii | |
A reaction: It seems more plausible to say that dispositions are first-order properties - that is, properties are dispositions, which are causal powers. A disposition to smoke is to have a causal power which leads to smoking. |
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. |
