15557 | Verisimilitude has proved hard to analyse, and seems to have several components [Lewis] |
Full Idea: The analysis of verisimilitude has been much debated. Some plausible analyses have failed disastrously, others conflict with one another. One conclusion is that verisimilitude seems to consist of several distinguishable virtues. | |
From: David Lewis (Causal Explanation [1986], V n7) | |
A reaction: Presumably if it is complex, you can approach truth in one respect while receding from it in another. It seems clear enough if you are calculating pi by some iterative process. |
15554 | A disposition needs a causal basis, a property in a certain causal role. Could the disposition be the property? [Lewis] |
Full Idea: I take for granted that a disposition requires a causal basis: one has the disposition iff one has a property that occupies a certain causal role. Shall we then identify the disposition with its basis? That makes the disposition cause its manifestations. | |
From: David Lewis (Causal Explanation [1986], III) | |
A reaction: Introduce the concept of a 'power' and I see no problem with his proposal. Fundamental dispositions are powerful, and provide the causal basis for complex dispositions. Something had better be powerful. |
15560 | We can explain a chance event, but can never show why some other outcome did not occur [Lewis] |
Full Idea: I think we are right to explain chance events, yet we are right also to deny that we can ever explain why a chance process yields one outcome rather than another. We cannot explain why one event happened rather than the other. | |
From: David Lewis (Causal Explanation [1986], VI) | |
A reaction: This misses out an investigation which slowly reveals that a 'chance' event wasn't so chancey after all. Failure to explain confirms chance, so the judgement of chance shouldn't block attempts to explain. |
19699 | A Gettier case is a belief which is true, and its fallible justification involves some luck [Hetherington] |
Full Idea: A Gettier case contains a belief which is true and well justified without being knowledge. Its justificatory support is also fallible, ...and there is considerable luck in how the belief combnes being true with being justified. | |
From: Stephen Hetherington (The Gettier Problem [2011], 5) | |
A reaction: This makes luck the key factor. 'Luck' is a rather vague concept, and so the sort of luck involved must first be spelled out. Or the varieties of luck that can produce this outcome. |
15559 | Does a good explanation produce understanding? That claim is just empty [Lewis] |
Full Idea: It is said that a good explanation ought to produce understanding, ...but this just says that a good explanation produces possession of that which it provide, so this desideratum is empty. It adds nothing to our understanding of explanation. | |
From: David Lewis (Causal Explanation [1986], V) | |
A reaction: I am not convinced by this dismissal. If you are looking for a test of whether an explanation is good, the announcement that the participants feel they have achieved a good understanding sounds like success. |
15556 | Science may well pursue generalised explanation, rather than laws [Lewis] |
Full Idea: The pursuit of general explanations may be very much more widespread in science than the pursuit of general laws. | |
From: David Lewis (Causal Explanation [1986], IV) | |
A reaction: Nice. I increasingly think that the main target of all enquiry is ever-widening generality, with no need to aspire to universality. |
15558 | A good explanation is supposed to show that the event had to happen [Lewis] |
Full Idea: It is said that a good explanation ought to show that the explanandum event had to happen, given the laws and circumstances. | |
From: David Lewis (Causal Explanation [1986], V) | |
A reaction: I cautiously go along with this view. Given that there are necessities in nature (a long story), we should aim to reveal them. There is no higher aspiration open to us than successful explanation. Lewis says good explanations can reveal falsehoods. |
4809 | Lewis endorses the thesis that all explanation of singular events is causal explanation [Lewis, by Psillos] |
Full Idea: Lewis endorses the thesis that all explanation of singular events is causal explanation. | |
From: report of David Lewis (Causal Explanation [1986]) by Stathis Psillos - Causation and Explanation p.237 | |
A reaction: It is hard to challenge this. The assumption is that only nomological and causal explanations are possible, and the former are unobtainable for singular events. |
14321 | To explain an event is to provide some information about its causal history [Lewis] |
Full Idea: Here is my main thesis: to explain an event is to provide some information about its causal history. | |
From: David Lewis (Causal Explanation [1986], II) | |
A reaction: The obvious thought is that you might provide some tiny and barely relevant part of that causal history, such as a bird perched on the Titanic's iceberg. So how do we distinguish the 'important' causal information? |
7222 | It is a crime for someone with a violent disposition to get drunk [Mill] |
Full Idea: The making himself drunk, in a person whom drunkenness excites to do harm to others, is a crime against others. | |
From: John Stuart Mill (On Liberty [1857], Ch.5) | |
A reaction: This principle (based on knowing your own dispositions) is a very good account of the ethics drunkenness. We have a moral duty to know and remember our own dispositions. Violent people should avoid arguments as well as alcohol. |
7214 | Ethics rests on utility, which is the permanent progressive interests of people [Mill] |
Full Idea: I regard utility as the ultimate appeal on all ethical questions; but it must be utility in the largest sense, grounded on the permanent interests of a man as a progressive being. | |
From: John Stuart Mill (On Liberty [1857], Ch.1) | |
A reaction: Mill, writing in praise of personal liberty, is desperate to introduce a paternalistic element into his politics, and the 'maximisation of happiness' will justify such paternalism, while his basic liberal principle (Idea 7211) won't. Mill's Dilemma. |
7212 | Individuals have sovereignty over their own bodies and minds [Mill] |
Full Idea: Over himself, over his own body and mind, the individual is sovereign. | |
From: John Stuart Mill (On Liberty [1857], Ch.1) | |
A reaction: If I should not even think about evil deeds, then neither should you. I would prevent you if I could. I would prevent you from drinking yourself to death, if I could. It is just that intrusions into private lives leads to greater trouble. |
7210 | The will of the people is that of the largest or most active part of the people [Mill] |
Full Idea: The will of the people practically means the will of the most numerous or the most active part of the people. | |
From: John Stuart Mill (On Liberty [1857], Ch.1) | |
A reaction: Hence the nicely coined modern phrase 'the silent majority', on whose behalf certain politicians, usually conservative, offer to speak. It is unlikely that the silent majority are actually deeply opposed to the views of the very active part. |
7227 | It is evil to give a government any more power than is necessary [Mill] |
Full Idea: Government interference should be restricted because of the great evil of adding unnecessarily to its power. | |
From: John Stuart Mill (On Liberty [1857], Ch.5) | |
A reaction: This would need justification, because it might be replied that individuals should not have unnecessary power either. The main problem is that governments have armies, police and money. |
7228 | Individuals often do things better than governments [Mill] |
Full Idea: Government power should be restricted because things are often done better by individuals. | |
From: John Stuart Mill (On Liberty [1857], Ch.5) | |
A reaction: This contains some truth, but it is obvious that innumerable things can be done better by governments, and also (and more importantly) that innumerable other good things might be done by governments which individuals can't be bothered to do. |
7230 | Aim for the maximum dissemination of power consistent with efficiency [Mill] |
Full Idea: The safest practical ideal is to aim for the greatest dissemination of power consistent with efficiency. | |
From: John Stuart Mill (On Liberty [1857], Ch.5) | |
A reaction: This is a very nice principle, which I would think desirable within an institution as well as on the scale of the state. I am becoming a fan of Mill's politics. I still say that freedom is an overrated virtue, so efficiency must be underrated. |
20515 | Maximise happiness by an area of strict privacy, and an area of utilitarian interventions [Mill, by Wolff,J] |
Full Idea: For Mill the greatest happiness will be achieved by giving people a private sphere of interests where no intervention is permitted, while allowing a public sphere where intervention is possible, but only on utilitarian grounds. | |
From: report of John Stuart Mill (On Liberty [1857]) by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 4 'Liberty' | |
A reaction: This is probably standard liberal practice nowadays. Freely consenting adult sexual activity is agreed to be wholly private. At least some lip-service is paid to increasing happiness when government intervenes. |
7229 | People who transact their own business will also have the initiative to control their government [Mill] |
Full Idea: A people accustomed to transacting their own business is certain to be free; it will never let itself be enslaved by any man or body of men because these are able to seize and pull the reins of the central administration. | |
From: John Stuart Mill (On Liberty [1857], Ch.5) | |
A reaction: He makes reference to Americans. This is an important idea, because it shows that democratic control is not just a matter of elections (which can be abolished or suborned), but is also a characteristic of a certain way of life. |
7211 | Prevention of harm to others is the only justification for exercising power over people [Mill] |
Full Idea: The only purpose for which power can be rightfully exercised over any member of a civilised community, against his will, is to prevent harm to others; his own good, either physical or moral, is not a sufficient warrant. | |
From: John Stuart Mill (On Liberty [1857], Ch.1) | |
A reaction: This is the key idea in Mill's liberalism, though he goes on to offer some qualifications of this absolute prohibition. I don't disagree with this principle, but there may be a lot more indirect harm than we realise (eg. in allowing liberal sex or drugs). |
7231 | The worth of a State, in the long run, is the worth of the individuals composing it [Mill] |
Full Idea: The worth of a State, in the long run, is the worth of the individuals composing it. | |
From: John Stuart Mill (On Liberty [1857], Ch.5) | |
A reaction: This is a key idea of liberalism, opposed to any idea that we should abandon our own value to that of our state. I agree, but communitarians can subscribe to this too, while disagreeing that maximum freedom is the strategy to follow. |
7217 | The main argument for freedom is that interference with it is usually misguided [Mill] |
Full Idea: The strongest of all the arguments against the interference of the public with purely personal conduct is that, when it does interfere, the odds are that it interferes wrongly, and in the wrong place. | |
From: John Stuart Mill (On Liberty [1857], Ch.4) | |
A reaction: This is also a well known objection to capital punishment. Generalised, well established, legal interferences are perhaps more likely to get it right than ad hoc decisions about individuals by individual officials. |
7213 | Liberty arises at the point where people can freely and equally discuss things [Mill] |
Full Idea: Liberty, as a principle, has no application to any state of things anterior to the time when mankind have become capable of being improved by free and equal discussion. | |
From: John Stuart Mill (On Liberty [1857], Ch.1) | |
A reaction: There is a Victorian (and Enlightenment) optimism here which a glimpse of the freedoms of the early twenty-first century might dampen. I doubt if Mill expected British tabloid newspapers, or porn on cable TV. Education and freedom connect. |
20516 | Mill defends freedom as increasing happiness, but maybe it is an intrinsic good [Wolff,J on Mill] |
Full Idea: Mill has presented liberty as instrumentally valuable, as a way of achieving the greatest possible happiness in society. But perhaps he should have argued that liberty is an intrinsic good, good in itself. | |
From: comment on John Stuart Mill (On Liberty [1857]) by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 4 'Intrinsic' | |
A reaction: If freedom is intrinsically good, does this leave us (as Wolff warned earlier) unable to defend its value? Freedom isn't an intrinsic good for infants, so why should it be so for adults? Good because it brings happiness, or fulfils our nature? |
20517 | Utilitarianism values liberty, but guides us on which ones we should have or not have [Mill, by Wolff,J] |
Full Idea: Utilitarianism provides an account of what liberties we should and should not have. Mill argues we should be free to compete in trade, but not to use another's property without consent. Thus he sets limits to liberty, while paying it great respect. | |
From: report of John Stuart Mill (On Liberty [1857]) by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 4 'Intrinsic' |
7215 | True freedom is pursuing our own good, while not impeding others [Mill] |
Full Idea: The only freedom which deserves the name, is that of pursuing our own good in our own way, so long as we do not attempt to deprive others of theirs, or impede their efforts to obtain it. | |
From: John Stuart Mill (On Liberty [1857], Ch.1) | |
A reaction: This principle will probably lead up a Prisoner's Dilemma cul-de-sac. The only freedom which deserves the name is the collective agreed freedom of a whole community to live well, when citizens volunteer to restrict their individual freedoms. |
7220 | Restraint for its own sake is an evil [Mill] |
Full Idea: All restraint, qua restraint, is an evil. | |
From: John Stuart Mill (On Liberty [1857], Ch.5) | |
A reaction: The ultimate justification for this is (presumably) utilitarian, but that would mean that there was nothing wrong with restraint if the person did not mind, or was not aware of the restraint. What is intrinsically wrong with restraint? |
7218 | Individuals are not accountable for actions which only concern themselves [Mill] |
Full Idea: My first maxim is that the individual is not accountable to society for his actions, in so far as these concern the interests of no person but himself. | |
From: John Stuart Mill (On Liberty [1857], Ch.5) | |
A reaction: This is a key idea of liberalism, and one which communitarians have doubts about (because it is almost impossible to perform an action which is of no interest, in the short or long term, to others). I share these doubts. |
7221 | Blocking entry to an unsafe bridge does not infringe liberty, since no one wants unsafe bridges [Mill] |
Full Idea: An official could turn a person back from an unsafe bridge without infringeing their liberty; for liberty consists in doing what one desires, and he does not desire to fall into the river. | |
From: John Stuart Mill (On Liberty [1857], Ch.5) | |
A reaction: Seems fair enough, but it justifies paternalist interference. The tricky one is where the official and the citizen disagree over what the citizen 'truly' desires. Asking people may involve too much time, but it could also involve too much effort. |
7223 | Pimping and running a gambling-house are on the border between toleration and restraint [Mill] |
Full Idea: A person being free to be a pimp, or to keep a gambling-house, lies on the exact boundary line between two principles, of toleration and of restraint. | |
From: John Stuart Mill (On Liberty [1857], Ch.5) | |
A reaction: Nothing illuminates a philosopher's principles more than for them to specify cases that lie on their borderlines. Both professions seem, unfortunately, to lead people into worse activities, such as violent bullying, or theft. Tricky.. |
7219 | Society can punish actions which it believes to be prejudicial to others [Mill] |
Full Idea: My second maxim is that for actions that are prejudicial to the interests of others, the individual is accountable, and subject to social or legal punishment, if society believes that this is requisite for its protection. | |
From: John Stuart Mill (On Liberty [1857], Ch.5) | |
A reaction: (wording compressed). The trouble with this would seem to be the possible disagreement between the individual and the society over whether the actions actually are prejudicial to others. It would justify a conservative society in being repressive. |
7226 | Benefits performed by individuals, not by government, help also to educate them [Mill] |
Full Idea: It is often desirable that beneficial things should be done by individuals, rather than by the government, as a means to their own mental education. | |
From: John Stuart Mill (On Liberty [1857], Ch.5) | |
A reaction: This raises the important danger, which even those on the political left must acknowledge, of the 'nanny state'. It offers a nicely paternalistic, and even patronising reason for giving people freedom, just as a parent might to a child. |
7224 | We need individual opinions and conduct, and State education is a means to prevent that [Mill] |
Full Idea: Individuality of character, and diversity in opinions and modes of conduct, involves diversity of education; a general State education is a mere contrivance for moulding people to be exactly like one another. | |
From: John Stuart Mill (On Liberty [1857], Ch.5) | |
A reaction: This strikes me as being particularly true with the advent in Britain of the National Curriculum in the early 1990s. However, if there is a pressure towards conformity in state education, private education is dominated by class and money. |
7225 | It is a crime to create a being who lacks the ordinary chances of a desirable existence [Mill] |
Full Idea: To bestow a life on someone which may be either a curse or a blessing, unless the being on whom it is to be bestowed will have at least the ordinary chances of a desirable existence, is a crime against that being. | |
From: John Stuart Mill (On Liberty [1857], Ch.5) | |
A reaction: This is the standard utilitarian attitude to engendering people. I think I have to agree. It is no argument against this to say that we value people with poor life prospects, once they have arrived. Altruism towards children may disguise selfish parents. |
15555 | Explaining match lighting in general is like explaining one lighting of a match [Lewis] |
Full Idea: Explaining why struck matches light in general is not so very different from explaining why some particular struck match lit. ...We may generalize modestly, without laying claim to universality. | |
From: David Lewis (Causal Explanation [1986], IV) | |
A reaction: A suggestive remark, since particular causation and general causation seem far apart, but Lewis suggests that the needs of explanation bring them together. Lawlike and unlawlike explanations? |
15551 | Ways of carving causes may be natural, but never 'right' [Lewis] |
Full Idea: There is no one right way - though there may be more or less natural ways - of carving up a causal history. | |
From: David Lewis (Causal Explanation [1986], I) | |
A reaction: This invites a distinction between the 'natural' causes and the 'real' causes. Presumably if any causes were 'real', they would have a better claim to be 'right'. Is an earthquake the 'real' (correct?) cause of a tsunami? |
15552 | We only pick 'the' cause for the purposes of some particular enquiry. [Lewis] |
Full Idea: Disagreement about 'the' cause is only disagreement about which part of the causal history is most salient for the purposes of some particular inquiry. | |
From: David Lewis (Causal Explanation [1986], I) | |
A reaction: I don't believe this. In the majority of cases I see the cause of an event, without having any interest in any particular enquiry. It is just so obvious that there isn't even a disagreement. Maybe there is only one sensible enquiry. |
15553 | Causal dependence is counterfactual dependence between events [Lewis] |
Full Idea: I take causal dependence to be counterfactual dependence, of a suitably back-tracking sort, between distinct events. | |
From: David Lewis (Causal Explanation [1986], I) | |
A reaction: He quotes Hume in support. 'Counterfactual dependence' strikes me as too vague, or merely descriptive, for the job of explanation. 'If...then' is a logical relationship; what is it in nature that justifies the dependency? |
7216 | The ethics of the Gospel has been supplemented by barbarous Old Testament values [Mill] |
Full Idea: To extract from the Gospel a body of ethical doctrine, has never been possible withouth eking it out from the Old Testament, that is, from a system elaborate indeed, but in many respects barbarous, and intended only for a barbarous people. | |
From: John Stuart Mill (On Liberty [1857], Ch.2) | |
A reaction: 'Barbarous' has a quaint Victorian ring to it, but his point is that the surviving teachings of Jesus are very thin and generalised. Christians would do better to expand their implications, than to borrow from the Old Testament. |
