8859 | The main modal logics disagree over three key formulae [Yablo] |
Full Idea: Lewis's different systems of modal logic differed about such formulae as □P implies □□P; ◊□P implies □P; and ◊S implies □◊S | |
From: Stephen Yablo (Apriority and Existence [2000], §06) | |
A reaction: Yablo's point is that the various version don't seem to make much difference to our practices in logic, mathematics and science. The problem, says Yablo, is deciding exactly what you mean by 'necessarily' and 'possibly'. |
8865 | If 'the number of Democrats is on the rise', does that mean that 50 million is on the rise? [Yablo] |
Full Idea: If someone says 'the number of Democrats is on the rise', he or she wants to focus on Democrats, not numbers. If the number is 50 million, is 50 million really on the rise? | |
From: Stephen Yablo (Apriority and Existence [2000], §14) | |
A reaction: This is a very nice warning from Yablo, against easy platonism, or any sort of platonism at all. We routinely say that numbers are 'increasing', but the real meaning needs entangling. Here it refers to people joining a party. |
8863 | We must treat numbers as existing in order to express ourselves about the arrangement of planets [Yablo] |
Full Idea: It is only by making as if to countenance numbers that one can give expression in English to a fact having nothing to do with numbers, a fact about stars and planets and how they are numerically proportioned. | |
From: Stephen Yablo (Apriority and Existence [2000], §13) | |
A reaction: To avoid the phrase 'numerically proportioned', he might have alluded to the 'pattern' of the stars and planets. I'm not sure which -ism this is, but it seems to me a good approach. The application is likely to precede the theory. |
8862 | Platonic objects are really created as existential metaphors [Yablo] |
Full Idea: The means by which platonic objects are simulated is existential metaphor. Numbers are conjured up as metaphorical measures of cardinality. | |
From: Stephen Yablo (Apriority and Existence [2000], §12) | |
A reaction: 'Fictional' might be a better word than 'metaphorical', since the latter usually implies some sort of comparison. |
8864 | We quantify over events, worlds, etc. in order to make logical possibilities clearer [Yablo] |
Full Idea: It is not that the contents of sentences are inexpressible without quantifying over events, worlds, etc. (they aren't). But the logical relations become much more tractable if we represent them quantificationally. | |
From: Stephen Yablo (Apriority and Existence [2000], §13) | |
A reaction: Yablo is explaining why we find ourselves committed to abstract objects. It is essentially, as I am beginning to suspect, a conspiracy of logicians. What on earth is 'the empty set' when it is at home? What's it made of? |
8858 | Philosophers keep finding unexpected objects, like models, worlds, functions, numbers, events, sets, properties [Yablo] |
Full Idea: There's a tradition in philosophy of finding 'unexpected objects' in truth-conditions, such as countermodels, possible worlds, functions, numbers, events, sets and properties. | |
From: Stephen Yablo (Apriority and Existence [2000], §02) | |
A reaction: This is a very nice perspective on the whole matter of abstract objects. If we find ourselves reluctantly committed to the existence of something which is ontologically peculiar, we should go back to the philosophical drawing-board. |
8861 | Hardly a word in the language is devoid of metaphorical potential [Yablo] |
Full Idea: There is hardly a word in the language - be it an adverb, preposition, conjunction, or what have you - that is devoid of metaphorical potential. | |
From: Stephen Yablo (Apriority and Existence [2000], §12) | |
A reaction: Yablo goes on to claim that metaphor is at the heart of all of our abstract thinking. 'Dead metaphors' (like the "mouth" of a river) sink totally into literal language. I think Yablo is on the right lines. |
8239 | If the King likes music then there is hope for the state [Mengzi (Mencius)] |
Full Idea: If the King has a great fondness for music, then perhaps there is hope for the state of Ch'i. | |
From: Mengzi (Mencius) (The Mengzi (Mencius) [c.332 BCE], 1.B.1) | |
A reaction: This seems to be Shakespeare's attitude to music as well. The general idea must be that love of music requires a selfless state of mind, where the mind revels in the beauty of something outside of itself. Respect is the desirable result. |
23398 | Human nature is naturally compassionate and good (as a 'sprout'), but people may not be good [Mengzi (Mencius), by Norden] |
Full Idea: Mengzi does not claim that humans are innately good; he claims that human nature is innately good. …He says that 'the heart of compassion' (manifested when anyone sees a child about to fall into a well) is the 'sprout of benevolence'. | |
From: report of Mengzi (Mencius) (The Mengzi (Mencius) [c.332 BCE]) by Bryan van Norden - Intro to Classical Chinese Philosophy 6.II | |
A reaction: There is a nice distinction here between the 'sprout' of human nature and the finished product. Seeds have the potential to produce tall healthy plants, but circumstances can warp them. |
23400 | Righteousness is extending the unthinkable, to reveal what must be done [Mengzi (Mencius)] |
Full Idea: People all have things they will not do. To extend this reaction to that which they will do is righteousness. | |
From: Mengzi (Mencius) (The Mengzi (Mencius) [c.332 BCE], 7B31), quoted by Bryan van Norden - Intro to Classical Chinese Philosophy 6.IV | |
A reaction: Very nice! Kekes points out the enormous importance of unthinkable deeds. Depravity is when the unthinkable gradually begins to look possible, which is probably a social phenomenon, a creeping cancer in a culture. |
23399 | Each correct feeling relies on an underlying virtue [Mengzi (Mencius)] |
Full Idea: The heart of compassion is benevolence. The heart of disdain is righteousness. The heart of respect is propriety. The heart of approval and disapproval is wisdom. | |
From: Mengzi (Mencius) (The Mengzi (Mencius) [c.332 BCE], 6A6), quoted by Bryan van Norden - Intro to Classical Chinese Philosophy 6.III | |
A reaction: 'Disdain' seems to be the response to anyone who is disrespectful. Note that wisdom concerns judgements. Respect seems to be more of a social convention than an actual concern for others. |
8235 | Should a coward who ran fifty paces from a battle laugh at another who ran a hundred? [Mengzi (Mencius)] |
Full Idea: If two soldiers were fleeing from a battle, and one stopped after a hundred paces and the other stopped after a fifty paces, what would you think if the latter, as one who only ran fifty paces, were to laugh at the former who ran a hundred? | |
From: Mengzi (Mencius) (The Mengzi (Mencius) [c.332 BCE], 1.A.3) | |
A reaction: A nice illustration, in my view, of the universality of truths about human virtue. In no culture would this laughter be appropriate. Nevertheless, there must be degrees of dishonour. Better to flee than join in with the likely winners. |
22673 | Wherever there is a small community, the association of the people is natural [Tocqueville] |
Full Idea: The village or township is the only association which is so perfectly natural that, wherever a number of men are collected, it seems to constitute itself. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.04) | |
A reaction: Seems like a chicken and egg issue. I would have thought that association precedes the development of a village. |
22676 | The people are just individuals, and only present themselves as united to foreigners [Tocqueville] |
Full Idea: The people in themselves are only individuals; and the special reason why they need to be united under one government is that they may appear to advantage before foreigners. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.07) | |
A reaction: I take this to be an observation on 1830s America, rather than a universal truth. It fits modern western societies rather well though. |
22679 | Vast empires are bad for well-being and freedom, though they may promote glory [Tocqueville] |
Full Idea: Nothing is more opposed to the well-being and the freedom of men than vast empires. …But there is a love of glory in those who regard the applause of a great people as a worthy reward. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.07) | |
A reaction: Presumably the main the problem is the central dominance over distant colonies. There may also be some freedom in being distant from the centres, especially in 1830. The Wild West. |
22680 | People would be much happier and freer in small nations [Tocqueville] |
Full Idea: If none but small nations existed, I do not doubt that mankind would be more happy and more free. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.07) | |
A reaction: In modern times many small states have appeared in Europe (in the Balkans and on the Baltic), and it looks to me a good thing. The prospect of Scottish independence may currently be looming, and De Tocqueville would approve. |
22675 | In American judges rule according to the Constitution, not the law [Tocqueville] |
Full Idea: The Americans have acknowledged the right of judges to found their decisions on the Constitution, rather than on the laws. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.05) | |
A reaction: Obviously the Constitution is one short document, so the details must be enshrined in the laws (which presumably defer to the Constitution). |
8240 | A true king shares his pleasure with the people [Mengzi (Mencius)] |
Full Idea: If you shared your enjoyment of music or of hunting with the people, you would be a true King. | |
From: Mengzi (Mencius) (The Mengzi (Mencius) [c.332 BCE], 1.B.1) | |
A reaction: I suspect that this is a great truth for dictators and traditional monarchs. One pictures the successful ones attending public entertainments, and allowing the public to see their own. Tyrants keep entertainment private. Nero is a counterexample! |
22677 | A monarchical family is always deeply concerned with the interests of the state [Tocqueville] |
Full Idea: The advantages of a monarchy are that the private interests of a family are connected with the interests of the state, …and at least there is always someone available to conduct the affairs of a monarchy. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.07) | |
A reaction: The second one is not much of a reason! The same defence can be given for the dominance of the Mafia. His defences are deliberately feeble, I suspect. England had plenty of monarchs who showed limited interest. |
22683 | Despots like to see their own regulations ignored, by themselves and their agents [Tocqueville] |
Full Idea: In despotic states the sovereign is so much attached to his power that he dislikes the constraints even of his own regulations, and likes to see his agents acting irregularly. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.11) | |
A reaction: A nice observation. What would Machiavelli say? At least the citizens can see where the real power resides. |
22669 | Aristocracy is constituted by inherited landed property [Tocqueville] |
Full Idea: Land is the basis of an aristocracy; …it is by landed property handed down from generation to generation that an aristocracy is constituted. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.01) | |
A reaction: Presumably there can be aristocrats by mere royal patronage, who have perhaps gambled away their land. They need protection by the other aristocrats. |
22674 | In Europe it is thought that local government is best handled centrally [Tocqueville] |
Full Idea: The partisans of centralisation in Europe are wont to maintain that the government can administer the affairs of each locality better than the citizens can do it for themselves. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.04) | |
A reaction: In the modern UK we have lots of local government, which is thoroughly starved of funds by the central government. He is contrasting it with the strong local system in the U.S. |
22678 | An election, and its lead up time, are always a national crisis [Tocqueville] |
Full Idea: The period which immediately precedes an election, and that during which the election is taking place, must always be considered as a national crisis. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.07) | |
A reaction: Rousseau said something similar. Election day in modern Britain is very peaceful and civilised, but it used to be chaotic. The weeks preceding it are invariably nasty. |
22682 | Universal suffrage is no guarantee of wise choices [Tocqueville] |
Full Idea: Universal suffrage is by no means a guarantee of the wisdom of the popular choice. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.11) | |
A reaction: This was precisely Plato's fear about democracy. There seems no way at all of preventing the people from electing representatives on superficial grounds of personality. |
8237 | Extend the treatment of the old and young in your family to the rest of society [Mengzi (Mencius)] |
Full Idea: Treat the aged of your own family in a manner befitting their venerable age and extend this treatment to the aged of other families. Treat your own young in a manner befitting their tender age, and extend this to the young of other families. | |
From: Mengzi (Mencius) (The Mengzi (Mencius) [c.332 BCE], 1.A.7) | |
A reaction: This seems to me to articulate the ideal of communitarianism very nicely. Morality is not just about healthy adults in war and peace. It must include the children and the old. The values of the family are above the values of contracts and calculations. |
22670 | Slavery undermines the morals and energy of a society [Tocqueville] |
Full Idea: Slavery dishonours labour; it introduces idleness into society, and with idleness, ignorance and pride, luxury and distress. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.01) | |
A reaction: A pretty feeble reason (in the 1830s) for disliking slavery. He seems only concerned with the adverse effects on the slave-owning society, and shows no interest in the slaves themselves. |
22681 | The liberty of the press is more valuable for what it prevents than what it promotes [Tocqueville] |
Full Idea: I approve of the liberty of the press from a consideration more of the evils it prevents than of the advantages it ensures. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.10) | |
A reaction: He accepts the freedom of the press as inevitable in a democracy, but he found U.S. newspapers to be nearly as bad then as they are now. |
22672 | It is admirable to elevate the humble to the level of the great, but the opposite is depraved [Tocqueville] |
Full Idea: One manly and lawful passion for equality elevates the humble to the rank of the great. But there exists also a depraved taste for equality, which impels the weak to attempt to lower the powerful to their own level. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.02) | |
A reaction: There is a distinction in modern political rhetoric between 'levelling down' and 'levelling up'. Since levelling down is just destructive, and levelling up is unaffordable, it seems obvious that true equality needs to be a compromise. |
22671 | Equality can only be established by equal rights for all (or no rights for anyone) [Tocqueville] |
Full Idea: I know of only two methods of establishing equality in the political world; rights must be given to every citizen, or none at all to anyone. | |
From: Alexis de Tocqueville (Democracy in America (abr Renshaw) [1840], 1.02) | |
A reaction: We may have a vague concept of 'natural' rights, but primarily they are a tool of social engineering. You could grant equal rights on inheritance, for example, which turn out in practice to hugely favour the rich. |
8241 | Only put someone to death if the whole population believes it is deserved [Mengzi (Mencius)] |
Full Idea: When close attendants say a man deserves death, do not listen; when all the councillors say so, do not listen; when everyone says so, have the case investigated. If he is guilty, put him to death; he was put to death by the whole country. | |
From: Mengzi (Mencius) (The Mengzi (Mencius) [c.332 BCE], 1.B.7) | |
A reaction: The jury system is a gesture in this direction. Compare Idea 95. In Mencius's time, no doubt, everyone believed that capital punishment was sometimes right. Nowadays, when many people (e.g. me) reject it, the procedure won't work. |
8238 | Seeking peace through war is like looking for fish up a tree [Mengzi (Mencius)] |
Full Idea: Your desire to extend your territory by war, in order to bring peace, is like looking for fish by climbing a tree. | |
From: Mengzi (Mencius) (The Mengzi (Mencius) [c.332 BCE], 1.A.7) | |
A reaction: Mencius had a flair for analogies. Just occasionally I suppose he might be wrong on this point, but I would think that experiments in the laboratory of history have shown that he is right in nearly all cases. |
8236 | Avoid the animals you are going to eat, as it is hard once you have got to know them [Mengzi (Mencius)] |
Full Idea: Once a gentleman has seen animals alive, he cannot bear to see them die, and once having heard their cry, he cannot bear to eat their flesh. That is why the gentleman keeps his distance from the kitchen. | |
From: Mengzi (Mencius) (The Mengzi (Mencius) [c.332 BCE], 1.A.7) | |
A reaction: If you applied this to a Gestapo officer and his victims, it would obviously be the epitome of wickedness. But it is complex. Compassion is expected when we encounter suffering, but we are not obliged to seek out suffering. Or are we? |
