5300 | Philosophers have interpreted the world, but the point is to change it [Marx] |
Full Idea: The philosophers have only interpreted the world, in various ways; the point is to change it. | |
From: Karl Marx (Theses on Feuerbach [1846], §XI) | |
A reaction: The 'point' of what? Personally I am more with Aristotle - that the aim is to create a society in which we can all aspire to contemplate like gods. As an interim statement of aim, though, one must respect Marx. But was he a philosopher? |
5297 | Whether human thinking can be 'true' must be decided in practice, not theory [Marx] |
Full Idea: The question whether objective truth can be attributed to human thinking is not a question of theory but is a practical question; man must prove the truth of his thinking in practice. | |
From: Karl Marx (Theses on Feuerbach [1846], §II) | |
A reaction: This would appear to be an assertion of the pragmatic view of truth well before Peirce. The obvious objections arise, such as whether falsehood (Plato's 'noble lie') might not have equal practical success, and whether truth might be disastrous. |
14239 | The empty set is usually derived from Separation, but it also seems to need Infinity [Oliver/Smiley] |
Full Idea: The empty set is usually derived via Zermelo's axiom of separation. But the axiom of separation is conditional: it requires the existence of a set in order to generate others as subsets of it. The original set has to come from the axiom of infinity. | |
From: Oliver,A/Smiley,T (What are Sets and What are they For? [2006], 1.2) | |
A reaction: They charge that this leads to circularity, as Infinity depends on the empty set. |
14240 | The empty set is something, not nothing! [Oliver/Smiley] |
Full Idea: Some authors need to be told loud and clear: if there is an empty set, it is something, not nothing. | |
From: Oliver,A/Smiley,T (What are Sets and What are they For? [2006], 1.2) | |
A reaction: I'm inclined to think of a null set as a pair of brackets, so maybe that puts it into a metalanguage. |
14241 | We don't need the empty set to express non-existence, as there are other ways to do that [Oliver/Smiley] |
Full Idea: The empty set is said to be useful to express non-existence, but saying 'there are no Us', or ¬∃xUx are no less concise, and certainly less roundabout. | |
From: Oliver,A/Smiley,T (What are Sets and What are they For? [2006], 1.2) |
14242 | Maybe we can treat the empty set symbol as just meaning an empty term [Oliver/Smiley] |
Full Idea: Suppose we introduce Ω not as a term standing for a supposed empty set, but as a paradigm of an empty term, not standing for anything. | |
From: Oliver,A/Smiley,T (What are Sets and What are they For? [2006], 1.2) | |
A reaction: This proposal, which they go on to explore, seems to mean that Ω (i.e. the traditional empty set symbol) is no longer part of set theory but is part of semantics. |
14243 | The unit set may be needed to express intersections that leave a single member [Oliver/Smiley] |
Full Idea: Thomason says with no unit sets we couldn't call {1,2}∩{2,3} a set - but so what? Why shouldn't the intersection be the number 2? However, we then have to distinguish three different cases of intersection (common subset or member, or disjoint). | |
From: Oliver,A/Smiley,T (What are Sets and What are they For? [2006], 2.2) |
14234 | If you only refer to objects one at a time, you need sets in order to refer to a plurality [Oliver/Smiley] |
Full Idea: A 'singularist', who refers to objects one at a time, must resort to the language of sets in order to replace plural reference to members ('Henry VIII's wives') by singular reference to a set ('the set of Henry VIII's wives'). | |
From: Oliver,A/Smiley,T (What are Sets and What are they For? [2006], Intro) | |
A reaction: A simple and illuminating point about the motivation for plural reference. Null sets and singletons give me the creeps, so I would personally prefer to avoid set theory when dealing with ontology. |
14237 | We can use plural language to refer to the set theory domain, to avoid calling it a 'set' [Oliver/Smiley] |
Full Idea: Plurals earn their keep in set theory, to answer Skolem's remark that 'in order to treat of 'sets', we must begin with 'domains' that are constituted in a certain way'. We can speak in the plural of 'the objects', not a 'domain' of objects. | |
From: Oliver,A/Smiley,T (What are Sets and What are they For? [2006], Intro) | |
A reaction: [Skolem 1922:291 in van Heijenoort] Zermelo has said that the domain cannot be a set, because every set belongs to it. |
14245 | Logical truths are true no matter what exists - but predicate calculus insists that something exists [Oliver/Smiley] |
Full Idea: Logical truths should be true no matter what exists, so true even if nothing exists. The classical predicate calculus, however, makes it logically true that something exists. | |
From: Oliver,A/Smiley,T (What are Sets and What are they For? [2006], 5.1) |
14246 | If mathematics purely concerned mathematical objects, there would be no applied mathematics [Oliver/Smiley] |
Full Idea: If mathematics was purely concerned with mathematical objects, there would be no room for applied mathematics. | |
From: Oliver,A/Smiley,T (What are Sets and What are they For? [2006], 5.1) | |
A reaction: Love it! Of course, they are using 'objects' in the rather Fregean sense of genuine abstract entities. I don't see why fictionalism shouldn't allow maths to be wholly 'pure', although we have invented fictions which actually have application. |
14247 | Sets might either represent the numbers, or be the numbers, or replace the numbers [Oliver/Smiley] |
Full Idea: Identifying numbers with sets may mean one of three quite different things: 1) the sets represent the numbers, or ii) they are the numbers, or iii) they replace the numbers. | |
From: Oliver,A/Smiley,T (What are Sets and What are they For? [2006], 5.2) | |
A reaction: Option one sounds the most plausible to me. I will take numbers to be patterns embedded in nature, and sets are one way of presenting them in shorthand form, in order to bring out what is repeated. |
22598 | The authentic self exists at the level of class, rather than the individual [Marx, by Dunt] |
Full Idea: Instead of focusing on the individual, Marxism suggested that the authentic self was at the social level in the form of class. | |
From: report of Karl Marx (Theses on Feuerbach [1846]) by Ian Dunt - How to be a Liberal 6 | |
A reaction: [not sure of the best source in Marx] This idea is expressed here by a defender of liberal individualism. Dunt persuasively attacks any concept of the self as part of some group, rather than as being an individual. |
5298 | The human essence is not found in individuals but in social relations [Marx] |
Full Idea: The human essence is no abstraction inherent in each single individual; in its reality it is the ensemble of the social relations. | |
From: Karl Marx (Theses on Feuerbach [1846], §VI) | |
A reaction: This is a key Marxist doctrine, and the central difference from Aristotle. Personally I am more with Aristotle, but the truth obviously lies somewhere in between. Man must be a 'social being', or there wouldn't be any social relations. |
23874 | Armies and businesses create moralities in which their activity can do no wrong [Marx, by Weil] |
Full Idea: Marx saw that social groups manufacture moralities for their own use, so their activity is placed outside the reach of evil. Thus the first articles of soldiers and businessmen is to deny that it is possible to do evil while waging war or doing business. | |
From: report of Karl Marx (works [1860]) by Simone Weil - Fragments: London 1943 p.146 | |
A reaction: This is especially true of the modern reverence for 'market forces'. It is a key debate in the ethics of warfare - compare Walzer and McMahon. A striking thought, obviously containing a lot of truth. |
22725 | When players don't meet again, defection is the best strategy [Axelrod] |
Full Idea: When players will never meet again, the strategy of defection is the only stable strategy. | |
From: Robert Axelrod (The Evolution of Co-Operation [1984], 5) | |
A reaction: This gives good grounds for any community's mistrust of transient strangers, such as tourists. And yet any sensible tourist will want communities to trust tourists, and will therefore behave in a reliable way. |
22724 | Good strategies avoid conflict, respond to hostility, forgive, and are clear [Axelrod] |
Full Idea: Successful game strategies avoid unnecessary conflict, are provoked by an uncalled for defection, forgive after a provocation, and behave clearly so the other player can adapt. | |
From: Robert Axelrod (The Evolution of Co-Operation [1984], 1) | |
A reaction: [compressed] Exactly what you would expect from a nice but successful school teacher. The strategies for success in these games is the same as the rules for educating a person into cooperative behaviour. TIT FOR TAT does all these. |
22001 | The real will of the cooperative will replace the 'will of the people' [Marx] |
Full Idea: Under collective property, the so called will of the people disappears in order to make way for the real will of the cooperative. | |
From: Karl Marx (Grundrisse [1876], p.563), quoted by Peter Singer - Marx 10 | |
A reaction: [from an 1874 note on Bakunin's 'Statism and Anarchy'] So how do you settle on the 'real' will of a cooperative? The travesty is when a ruling elite decide that, without consultation. An institution is needed. This is still a social contract. |
21991 | The middle class gain freedom through property, but workers can only free all of humanity [Marx, by Singer] |
Full Idea: Where the middle class can win freedom for themselves on the basis of rights to property - thus excluding others from their freedom - the working class have nothing but their title as human beings. They only liberate themselves by liberating humanity. | |
From: report of Karl Marx (Contrib to Critique of Hegel's Phil of Right [1844]) by Peter Singer - Marx 4 | |
A reaction: Individual workers might gain freedom via education, marriage, or entrepreneurship, or by opting for total simplicity of life, but in general Marx seems to be right about this. But we must ask what sort of 'freedom' is needed. |
21990 | Theory is as much a part of a revolution as material force is [Marx] |
Full Idea: Material force must be overthrown by material force. But theory also becomes a material force once it has gripped the masses. | |
From: Karl Marx (Contrib to Critique of Hegel's Phil of Right [1844], Intro p.69), quoted by Peter Singer - Marx 4 | |
A reaction: A huge problem, I think, is that every theory (even conservatism) has to be simplified in a democracy if it is to grip the imagination of the majority. My current hatred is labels in political philosophy. They give us a cartoon view of the world. |
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. |
18662 | Liberal freedom is the right to be separate, and ignores the union of man with man [Marx] |
Full Idea: The liberal right of man to freedom is not based on the union of man with man, but on the separation of man from man; it is the right to this separation. | |
From: Karl Marx (works [1860]), quoted by Will Kymlicka - Contemporary Political Philosophy (1st edn) 7.2.a | |
A reaction: [quoted from an anthology] It is interesting that liberal freedom is the right NOT to be involved in politics, and even not to vote in elections. Home counties England (high hedges etc) is the embodiment of the freedom not to be involved in society. |
23372 | Liberals want the right to be separate, rather than for people to be united [Marx] |
Full Idea: The [liberal] right of man to freedom is not based on the union of man with man, but on the separation of man from man. It is the right to this separation. | |
From: Karl Marx (works [1860], p.53), quoted by Will Kymlicka - Contemporary Political Philosophy (2nd edn) 7 | |
A reaction: [in collection ed.McLelland p.53] That nicely encapsulates the debate. Modern liberal thinkers regret the loss of community, but people in authoritarian communities yearn for separation. You can have too much 'union'! |
20576 | Early Marx anticipates communitarian objections to liberalism [Marx, by Oksala] |
Full Idea: The early writings of Marx anticipate the communitarian critique of liberalism. | |
From: report of Karl Marx (works [1860]) by Johanna Oksala - Political Philosophy: all that matters Ch.8 | |
A reaction: [Oksala says modern writers seem to prefer this to the hardcore later Marx, which is presumably too 'scientific'. He says 'Capital Vol 1' is Marx's most important work] |
21989 | Man is dominated by money, which is the essence of his alienation [Marx] |
Full Idea: Money is the alienated essence of man's labour and life, and this alien essence dominates him as he worships it. | |
From: Karl Marx (On the Jewish Question [1844], p.60), quoted by Peter Singer - Marx 3 | |
A reaction: Presumably this is inherit in the very nature of money, rather than in the wickedness of capitalists who control it. But money is not inherently alienting for the rich, or for the comfortable bourgeoisie (is it?). |
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. |
23862 | By saying the material dialectic of history aspires to the best, Marx agreed with capitalism [Weil on Marx] |
Full Idea: When Marx inverted Hegel's dialectic of history, by substituting matter for mind as the motive, he attributed to matter the essence of mind, an unceasing aspiration towards the best - which was in keeping with the general current of capitalist thought. | |
From: comment on Karl Marx (works [1860]) by Simone Weil - Reflections on Liberty and Social Oppression p.43 | |
A reaction: [compressed] A rather nice debating point! Marx seems to share the universal nineteenth century belief in unremitting progress. Without that, it is impossible to believe that a revolution will necessarily improve anything. |
21999 | False consciousness results from concealment by the superstructure [Marx, by Singer] |
Full Idea: False consciousness involves failing to see things as they really are. It comes about because a society's superstructure can conceal the real basis of the society. | |
From: report of Karl Marx (works [1860]) by Peter Singer - Marx 9 | |
A reaction: That seems a poor label, probably revealing a Hegelian background. It seems a matter of knowledge rather than consciousness. Can a whole mind be in a state of error? |
23875 | Marx says force is everything, and that the weak will become strong, while remaining the weak [Weil on Marx] |
Full Idea: Marx posits on the one hand that force alone governs social relations to the exclusion of anything else, and on the other hand that one day the weak, while remaining weak, will nevertheless be stronger. He believed in miracles. | |
From: comment on Karl Marx (works [1860]) by Simone Weil - Fragments: London 1943 p.149 | |
A reaction: This is close to the obvious contradiction if the working classes despise the middle classes (the dreaded 'bourgeoisie') while their only aspiration is to be like them. It is hard to custom design a new class to which they could both aspire. |
21995 | Must production determine superstructure, or could it be the other way round? [Singer on Marx] |
Full Idea: Once the 'interaction' between the superstructure and the productive forces is admitted, is it still possible to maintain that production determines the superstructure, rather than the other way round? | |
From: comment on Karl Marx (Capital Vol. 1 [1867]) by Peter Singer - Marx 7 | |
A reaction: It is much harder to defend historical determinism if Singer is right about this. Modern capitalism won't admit of the sort of simple distinctions that mark was looking for. |
18653 | Marx rejected equal rights because they never actually treat people as equals [Marx, by Kymlicka] |
Full Idea: Marx rejected the idea of equal rights, not because he was not a friend to the idea of treating people as equals, but precisely because he thought rights failed to live up to that ideal. | |
From: report of Karl Marx (works [1860]) by Will Kymlicka - Contemporary Political Philosophy (1st edn) 5.1 | |
A reaction: Presumably because the power to award 'rights' goes to the highest bidder. If equality is to be enshrined in law, it is a bit difficult to see how else to manage it. |
20577 | Even decently paid workers still have their produce bought with money stolen from them [Marx] |
Full Idea: Even if the workers are paid a fair wage, the whole thing still remains the age-old activity of the conqueror, who buys commodities from the conquered with the money has has stolen from them, | |
From: Karl Marx (Capital Vol. 1 [1867], p.728), quoted by Johanna Oksala - Political Philosophy: all that matters Ch.8 | |
A reaction: [Penguin edition cited] The word 'stolen' is obviously dubious here. 'Exploitation' is a much more accurate word. One might talk of 'blackmail' or 'extortion' rather than theft. |
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. |
21996 | Freedom only comes when labour is no longer necessary [Marx] |
Full Idea: The realm of freedom actually begins only where labour which is determined by necessity and mundane considerations ceases. | |
From: Karl Marx (Capital Vol. 3 [1873], p.496), quoted by Peter Singer - Marx 8 | |
A reaction: This is a bit discouraging fo idealistic dreamers. Modern political thought needs an ecological dimension to this problem. If society always needs a fair degree of labour, there must be a way to maximise freedom in that context. |
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! |
21994 | The handmill gives feudalism, the steam mill capitalism [Marx] |
Full Idea: The handmill gives you society with the feudal lord; the steam mill society with the industrial capitalist. | |
From: Karl Marx (The Poverty of Philosophy [1847], p.202), quoted by Peter Singer - Marx 7 | |
A reaction: If technology dictates social structure, then feudalism is still with us, in low-tech industries. What if the steam mill had been invented in 1300? |
20958 | Capitalism changes the world, by socialising the idea of a commodity [Marx, by Bowie] |
Full Idea: In Marx's view the essential factor in capitalism is that the encroachment of the commodity form into society fundamentally changes the world. | |
From: report of Karl Marx (works [1860]) by Andrew Bowie - Introduction to German Philosophy 6 'Historical' | |
A reaction: The main point is that people and their labour become commodities. Haven't animals always been treated as commodities? Clearly slave were commodities, long before capitalism. Capitalism universalises it? |
23876 | The essence of capitalism is the subordination of people to things [Marx, by Weil] |
Full Idea: Marx discovered a formula impossible to surpass when he said that the essence of capitalism lies in the subordination of subject to object, of man to thing. | |
From: report of Karl Marx (works [1860]) by Simone Weil - Fragments: London 1943 p,155 | |
A reaction: I find this rather too vague to be a penetrating observation. I would suggest the obliteration of cooperation and community, in favour of competition. Winners and losers. |
20960 | Marx thought capitalism was partly liberating, and could make labour and ownership more humane [Marx, by Bowie] |
Full Idea: Marx did not disapprove per se of capitalism. New divisions of labour and forms of ownership could transform individuals in modern societies, creating a more humane world with the means capitalism had liberated from feudalism. | |
From: report of Karl Marx (works [1860]) by Andrew Bowie - Introduction to German Philosophy 11 'Metaphysics' | |
A reaction: I'm guessing this might be early Marx, which has less to say about the 'scientific' inevitably of deep change, and the necessity for revolution. Nowadays we tinker with humane changes at the poorer end, while the rich run rampant. |
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. |
20519 | Marxists say liberal rights are confrontational, and liberal equality is a sham [Marx, by Wolff,J] |
Full Idea: For Marx liberal rights are egoistic rights of separation: they encourage each individual to view others as limitations to his or her freedom. ....Liberals set up a sham community of 'equal' citizens. | |
From: report of Karl Marx (On the Jewish Question [1844]) by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 4 'Marxist' | |
A reaction: The point is that equality in law does not ensure equal treatment in daily life. I suppose a liberal right can be seen as an opt-out clause for some aspect of society. |
7128 | Religion is the opium of the people, and real happiness requires its abolition [Marx] |
Full Idea: Religion is the opium of the people. The abolition of religion as the illusory happiness of the people is required for their real happiness. | |
From: Karl Marx (Contrib to Critique of Hegel's Phil of Right [1844], Intro) | |
A reaction: Not being religious myself, I have some sympathy with this ringing clarion-call. However, while opium satisfies an artificial and superficial need, religion certainly seems to speak to something deeper and more central in people. |
5299 | Religious feeling is social in origin [Marx] |
Full Idea: The "religious sentiment" (discussed by Feuerbach) is itself a social product. | |
From: Karl Marx (Theses on Feuerbach [1846], §VII) | |
A reaction: Recent brain research has identified a part of the brain which is only active during religious thought and experience. It is easy to produce cynical political accounts of religion, but in its time it was also quite a good scientific account of nature. |
