9 ideas
22593 | Our sensation of light may not be the same as what produces the sensation [Descartes] |
Full Idea: There can be a difference between our sensation of light and what is in the objects that produce that sensation in us. | |
From: René Descartes (The World [1631]), quoted by Ian Dunt - How to be a Liberal 1 | |
A reaction: Note only that they 'may' differ, and that he does not assert that they are entirely different. Secondary qualities give information, and are not just mental events. |
1590 | The just man does not harm his enemies, but benefits everyone [Plato] |
Full Idea: First, Socrates, you told me justice is harming your enemies and helping your friends. But later it seemed that the just man, since everything he does is for someone's benefit, never harms anyone. | |
From: Plato (Clitophon [c.372 BCE], 410b) | |
A reaction: Socrates certainly didn't subscribe to the first view, which is the traditional consensus in Greek culture. In general Socrates agreed with the views later promoted by Jesus. |
22971 | In moving from capitalism to communism a revolutionary dictatorship of the proletariat is needed [Marx] |
Full Idea: Between the capitalist and communist society lies the revolutionary transformation of the one into the other. Corresponding to this is a political transition period in which the state can be nothing but the revolutionary dictatorship of the proletariat. | |
From: Karl Marx (Critique of the Gotha Program [1875], IV) | |
A reaction: This hugely influential idea was catastrophic for the twentieth century, because the leaders of the proletarian dictatorship adored and abused the power, and wouldn't give it up for some feeble next stage. |
22000 | From each according to his ability, to each according to his need [Marx] |
Full Idea: From each according to his ability, to each according to his need. | |
From: Karl Marx (Critique of the Gotha Program [1875]), quoted by Peter Singer - Marx 9 | |
A reaction: Singer says this was not original to Marx, and he placed little emphasis on it. The obvious capitalist response is to ask how you will motivate someone who has huge abilities but few needs. It implies huge inequalities of altruism. |
22969 | People who only have their labour power are the slaves of those permitting them to work [Marx] |
Full Idea: The man who possesses no other property than his labour power must, in all conditions of society and culture, be the slave of other men who have made themselves the owners of the material conditions of labour. He can only work with their permission. | |
From: Karl Marx (Critique of the Gotha Program [1875], I) | |
A reaction: In a world of vast multinationals, the person giving the permission to work is nearly always dependent on some higher level permission. In any sort of society people can only work with the consensus of other people. |
22970 | Freedom is making the state subordinate to its society [Marx] |
Full Idea: Freedom consists in converting the state from an organ superimposed on society into one completely subordinate to it. | |
From: Karl Marx (Critique of the Gotha Program [1875], IV) | |
A reaction: The intermediate stage is dictatorship of the proletariat (presumably exercised by the communist leadership). No twentieth century marxist state ever got near the freedom which Marx was seeking. A liberal society might achieve it! |
22972 | Bourgeois 'freedom of conscience' just tolerates all sorts of religious intolerance [Marx] |
Full Idea: Bourgeois 'freedom of conscience' is just the toleration of all possible kinds of religious unfreedom of conscience, and the workers' party should endeavour to liberate the conscience from the witchery of religion. | |
From: Karl Marx (Critique of the Gotha Program [1875], IV) | |
A reaction: We see this in modern 'faith' schools in the UK, which do not seem to be required to live up to the standards of freedom of belief expected in the rest of a liberal society. |
16569 | The Hot, Cold, Wet and Dry of the philosophers need themselves to be explained [Descartes] |
Full Idea: If you find it strange that in explaining these elements I do not use the qualities called Hot, Cold, Wet and Dry - as the philosophers do - I shall say to you that these qualities themselves seem to me to need explanation. | |
From: René Descartes (The World [1631], 9:25-6), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 1.3 | |
A reaction: Nice. I take pushing the boundaries of explanation back (or down) to be the basic driving force of all human thought, in metaphysics as well as in physics. |
20964 | Descartes said there was conservation of 'quantity of motion' [Descartes, by Papineau] |
Full Idea: Descartes incorporated the conservation of what he called 'quantity of motion', by which he meant mass times speed. | |
From: report of René Descartes (The World [1631]) by David Papineau - Thinking about Consciousness App 2 | |
A reaction: Mass times velocity is now called 'momentum'. Is this the first ever conservation law? There are now lots of them. |
