| 9331 | How do we determine which of the sentences containing a term comprise its definition? [Horwich] |
| Full Idea: How are we to determine which of the sentences containing a term comprise its definition? | |
| From: Paul Horwich (Stipulation, Meaning and Apriority [2000], §2) | |
| A reaction: Nice question. If I say 'philosophy is the love of wisdom' and 'philosophy bores me', why should one be part of its definition and the other not? What if I stipulated that the second one is part of my definition, and the first one isn't? |
| 22180 | Multiple realisability is said to make reduction impossible [Okasha] |
| Full Idea: Philosophers have often invoked multiple realisability to explain why psychology cannot be reduced to physics or chemistry, but in principle the explanation works for any higher-level science. | |
| From: Samir Okasha (Philosophy of Science: Very Short Intro (2nd ed) [2016], 3) | |
| A reaction: He gives the example of a 'cell' in biology, which can be implemented in all sorts of ways. Presumably that can be reduced to many sorts of physics, but not just to one sort. The high level contains patterns that vanish at the low level. |
| 9333 | A priori belief is not necessarily a priori justification, or a priori knowledge [Horwich] |
| Full Idea: It is one thing to believe something a priori and another for this belief to be epistemically justified. The latter is required for a priori knowledge. | |
| From: Paul Horwich (Stipulation, Meaning and Apriority [2000], §8) | |
| A reaction: Personally I would agree with this, because I don't think anything should count as knowledge if it doesn't have supporting reasons, but fans of a priori knowledge presumably think that certain basic facts are just known. They are a priori justified. |
| 9342 | Understanding needs a priori commitment [Horwich] |
| Full Idea: Understanding is itself based on a priori commitment. | |
| From: Paul Horwich (Stipulation, Meaning and Apriority [2000], §12) | |
| A reaction: This sounds plausible, but needs more justification than Horwich offers. This is the sort of New Rationalist idea I associate with Bonjour. The crucial feature of the New lot is, I take it, their fallibilism. All understanding is provisional. |
| 9332 | Meaning is generated by a priori commitment to truth, not the other way around [Horwich] |
| Full Idea: Our a priori commitment to certain sentences is not really explained by our knowledge of a word's meaning. It is the other way around. We accept a priori that the sentences are true, and thereby provide it with meaning. | |
| From: Paul Horwich (Stipulation, Meaning and Apriority [2000], §8) | |
| A reaction: This sounds like a lovely trump card, but how on earth do you decide that a sentence is true if you don't know what it means? Personally I would take it that we are committed to the truth of a proposition, before we have a sentence for it. |
| 9341 | Meanings and concepts cannot give a priori knowledge, because they may be unacceptable [Horwich] |
| Full Idea: A priori knowledge of logic and mathematics cannot derive from meanings or concepts, because someone may possess such concepts, and yet disagree with us about them. | |
| From: Paul Horwich (Stipulation, Meaning and Apriority [2000], §12) | |
| A reaction: A good argument. The thing to focus on is not whether such ideas are a priori, but whether they are knowledge. I think we should employ the word 'intuition' for a priori candidates for knowledge, and demand further justification for actual knowledge. |
| 9334 | If we stipulate the meaning of 'number' to make Hume's Principle true, we first need Hume's Principle [Horwich] |
| Full Idea: If we stipulate the meaning of 'the number of x's' so that it makes Hume's Principle true, we must accept Hume's Principle. But a precondition for this stipulation is that Hume's Principle be accepted a priori. | |
| From: Paul Horwich (Stipulation, Meaning and Apriority [2000], §9) | |
| A reaction: Yet another modern Quinean argument that all attempts at defining things are circular. I am beginning to think that the only a priori knowledge we have is of when a group of ideas is coherent. Calling it 'intuition' might be more accurate. |
| 9339 | A priori knowledge (e.g. classical logic) may derive from the innate structure of our minds [Horwich] |
| Full Idea: One potential source of a priori knowledge is the innate structure of our minds. We might, for example, have an a priori commitment to classical logic. | |
| From: Paul Horwich (Stipulation, Meaning and Apriority [2000], §11) | |
| A reaction: Horwich points out that to be knowledge it must also say that we ought to believe it. I'm wondering whether if we divided the whole territory of the a priori up into intuitions and then coherent justifications, the whole problem would go away. |
| 22177 | Randomised Control Trials have a treatment and a control group, chosen at random [Okasha] |
| Full Idea: In the Randomised Controlled Trial for a new drug, patients are divided at random into a treatment group who receive the drug, and a control group who do not. Randomisation is important to eliminate confounding factors. | |
| From: Samir Okasha (Philosophy of Science: Very Short Intro (2nd ed) [2016], 2) | |
| A reaction: [compressed] Devised in the 1930s, and a major breakthrough in methodology for that kind of trial. Psychologists use the method all the time. Some theorists say it is the only reliable method. |
| 22172 | Not all sciences are experimental; astronomy relies on careful observation [Okasha] |
| Full Idea: Not all sciences are experimental - astronomers obviously cannot do experiments on the heavens, but have to content themselves with careful observation instead. | |
| From: Samir Okasha (Philosophy of Science: Very Short Intro (2nd ed) [2016], 1) | |
| A reaction: Biology too. Psychology tries hard to be experimental, but I doubt whether the main theories emerge from experiments. |
| 22174 | The discoverers of Neptune didn't change their theory because of an anomaly [Okasha] |
| Full Idea: Adams and Leverrier began with Newton's theory of gravity, which made an incorrect prediction about the orbit of Uranus. They explained away the conflicting observations by postulating a new planet, Neptune. | |
| From: Samir Okasha (Philosophy of Science: Very Short Intro (2nd ed) [2016], 1) | |
| A reaction: The falsificationists can say that the anomalous observation did not falsify the theory, because they didn't know quite what they were observing. It was not in fact an anomaly for Newtonian theory at all. |
| 22175 | Science mostly aims at confirming theories, rather than falsifying them [Okasha] |
| Full Idea: The goal of science is not solely to refute theories, but also to determine which theories are true (or probably true). When a scientist collects data …they are trying to show that their own theory is true. | |
| From: Samir Okasha (Philosophy of Science: Very Short Intro (2nd ed) [2016], 2) | |
| A reaction: This is the aim of 'accommodation' to a wide set of data, rather than prediction or refutation. |
| 22182 | Theories with unobservables are underdetermined by the evidence [Okasha] |
| Full Idea: According to anti-realists, scientific theories which posit unobservable entities are underdetermined by the empirical data - there will always be a number of competing theories which can account for the data equally well. | |
| From: Samir Okasha (Philosophy of Science: Very Short Intro (2nd ed) [2016], 4) | |
| A reaction: The fancy version is Putnam's model theoretic argument, explored by Tim Button. The reply, apparently, is that there are other criteria for theory choice, apart from the data. And we don't have to actually observe everything in a theory. |
| 22185 | Two things can't be incompatible if they are incommensurable [Okasha] |
| Full Idea: If two things are incommensurable they cannot be incompatible. | |
| From: Samir Okasha (Philosophy of Science: Very Short Intro (2nd ed) [2016], 5) | |
| A reaction: Kuhn had claimed that two rival theories are incompatible, which forces the paradigm shift. He can't stop the slide off into total relativism. The point is there cannot be a conflict if there cannot even be a comparison. |
| 22176 | Induction is inferences from examined to unexamined instances of a given kind [Okasha] |
| Full Idea: Some philosophers use 'inductive' to just mean not deductive, …but we reserve it for inferences from examined to unexamined instances of a given kind. | |
| From: Samir Okasha (Philosophy of Science: Very Short Intro (2nd ed) [2016], 2) | |
| A reaction: The instances must at least be comparable. Must you know the kind before you start? Surely you can examine a sequence of things, trying to decide whether or not they are of one kind? Is checking the uniformity of a kind induction? |
| 22178 | If the rules only concern changes of belief, and not the starting point, absurd views can look ratiional [Okasha] |
| Full Idea: If the only objective constraints concern how we should change our credences, but what our initial credences should be is entirely subjective, then individuals with very bizarre opinions about the world will count as perfectly rational. | |
| From: Samir Okasha (Philosophy of Science: Very Short Intro (2nd ed) [2016], 2) | |
| A reaction: The important rationality has to be the assessement of a diverse batch of evidence, for which there can never be any rules or mathematics. |
| 22849 | Rawls's theory cannot justify liberalism, since it presupposes free and equal participants [Charvet] |
| Full Idea: Rawls's theory presupposes that the contractors are conceived, and conceive themselves, to be free and equal persons. Consequently, the theory cannot be presented as a justificatory theory of liberalism. | |
| From: John Charvet (Liberalism: the basics [2019], 14) | |
| A reaction: Nice. If you imagine diverse groups with many strong beliefs coming together to form a society, Rawls is asking them all to become liberals before they all decide how to live together. |
| 22848 | People with strong prior beliefs would have nothing to do with a veil of ignorance [Charvet] |
| Full Idea: Why would a group of people with strong beliefs (e.g. religious beliefs) agree to debate the problem of what norms should govern their association from behind a veil of ignorance? …They would not accept the veil of ignorance as fair. | |
| From: John Charvet (Liberalism: the basics [2019], 14) | |
| A reaction: Nice. Rawls's experiment assumes liberal people with very few beliefs. No racial supremacist is going to enter a society in which they may be of a different race. Charvet says the entrants would all need to be pluralists about the good. |
| 22838 | Societies need shared values, so conservatism is right if rational discussion of values is impossible [Charvet] |
| Full Idea: Were it true that rational discussion of values is impossible, then a conservative attitude would seem to be the only viable position. Some set of common values is necessary to maintain the unity of a political society. | |
| From: John Charvet (Liberalism: the basics [2019], 07) | |
| A reaction: Better to say that the less values can be both discussed and changed the stronger is the case for a degree of conservatism. Conservatives tend to favour values asserted by authority, rather than by popular (undiscussed) consensus. |
| 22846 | The universalism of utilitarianism implies a world state [Charvet] |
| Full Idea: Utilitarianism is a universalist ethic, so the political realisation of this ethic would seem to be a world state seeking to maximise happiness for the world's population. | |
| From: John Charvet (Liberalism: the basics [2019], 12) | |
| A reaction: It certainly doesn't seem to favour the citizens of the state where it is implemented, since miserable people just across the border would have priority, and all miserable migrants must be welcomed. There is no loyalty to citizens. |
| 22835 | Liberals value freedom and equality, but the society itself must decide on its values [Charvet] |
| Full Idea: While freedom and equality are liberal values …they are fundamental regulative ideas of an independent society that is self-regulating …and decides what its own social and political arrangements should be. | |
| From: John Charvet (Liberalism: the basics [2019], 06) | |
| A reaction: So the central political activity is persuasion, not enforcement. Illiberal societies all contain liberal individuals. |
| 22831 | Modern libertarian societies still provide education and some housing [Charvet] |
| Full Idea: No society today is libertarian in the extreme sense. Even the freest economically, such as Singapore have their governments provide education services and public housing. | |
| From: John Charvet (Liberalism: the basics [2019], 05) | |
| A reaction: There is a good argument that many other services should be provided by a libertarian state, on the grounds that it is more efficient, and the services must otherwise paid for by much higher salaries. |
| 22839 | Liberalism needs people to either have equal autonomy, or everyone to have enough autonomy [Charvet] |
| Full Idea: To get a liberal society one would have to claim that either everyone possesses autonomy to an equal degree or that everyone possesses a threshold level of the capacity that entitles them to enjoy the full liberal rights. | |
| From: John Charvet (Liberalism: the basics [2019], 07) | |
| A reaction: This leaves out the more right-wing attitude that people can increase their capacity for autonomy if they are forced to stand on their own feet. A liberal society must decide how to treat persons incapable of proper autonomy. |
| 22847 | Kant places a higher value on the universal rational will than on the people asserting it [Charvet] |
| Full Idea: For Kant what is of absolute worth is the universal rational will which become an individual's actual will. Insofar as the individual fails to will the universal, they have no absolute worth, so whether or not they exist is unimportant. | |
| From: John Charvet (Liberalism: the basics [2019], 14) | |
| A reaction: A lovely demolition of the claims of Kant to be the patriarch of liberalism! Liberalism must place supreme value on each individual, not on some abstracted realm of pure reason and moral good. Liberals are motivated by love, not reason. |
| 22821 | Liberalism asserts maximum freedom, but that must be equal for all participants [Charvet] |
| Full Idea: Liberalism attaches fundamental value to leaving individuals as free as possible … - but there is another fundamental value implicit in this idea - the equal status of the participants in the practice. By this I mean that they all have the same rights. | |
| From: John Charvet (Liberalism: the basics [2019], Intro) | |
| A reaction: Libertarian liberalism (e.g. Nozick) only asserts the fundament principle of freedom, but such a society swiftly deprives most of its members of those very freedoms. Egalitarian Liberalism should be our default political ideology. |
| 22834 | Egalitarian liberals prefer equality (either of input or outcome) to liberty [Charvet] |
| Full Idea: Rather than libertarianism, egalitarian liberals promote equality, either of outcomes (of happiness or of well-being), or of inputs (such as opportunities, capacities or resources), which they favour ahead of freedom. | |
| From: John Charvet (Liberalism: the basics [2019], 06) | |
| A reaction: This is my team, I think. I think I'm a liberal who thinks liberty is a bit overrated. Equal outcome according to capacity (promoted by Nussbaum) seems attractive. |
| 22822 | Liberals promote community and well-being - because all good societies need them [Charvet] |
| Full Idea: Community and well-being are not specifically liberal values. They are values any independent political society must pursue whether it is a liberal society or not. | |
| From: John Charvet (Liberalism: the basics [2019], Intro) | |
| A reaction: This seems, at a stroke, to undermine the familiar debate between liberals and communitarians. I've switched to the former from the latter, because communitarians is potentially too paternalistic and conservative. Persuade individuals to be communal! |
| 22841 | Identity multiculturalism emerges from communitarianism, preferring community to humanity [Charvet] |
| Full Idea: Identity-based multiculturalism developed from communitarianism. …People come to consciousness of themselves as members of some community before they identify themselves as members of the human race. | |
| From: John Charvet (Liberalism: the basics [2019], 08) | |
| A reaction: This is 'identity politics', which Carvet sees as a problem from liberalism. Is it more important to be a woman or a Muslim or a Scot than to be a human being? It seems to create institutional antagonisms. |
| 22842 | For communitarians it seems that you must accept the culture you are born into [Charvet] |
| Full Idea: Communitarians have difficulty avoiding the relativist trap. It seems they must claim that if one is born into a liberal society one cannot but be a liberal, and if one is born into a communist society one cannot but be a communist. | |
| From: John Charvet (Liberalism: the basics [2019], 08) | |
| A reaction: Anyone who accepts the Hegelian view of history and culture seems doomed to such relativism, and Hegel is a communitarian precursor. This is a good reason for me to reject communitarianism, after a long flirtation. We can criticise our own culture. |
| 22830 | Give by ability and receive by need, rather than a free labour market [Charvet] |
| Full Idea: Only the most extreme collective socialism denies the freedom to sell one's labour power and buy that of others, under the communist slogan 'from each according to his ability, and to each according to his needs'. | |
| From: John Charvet (Liberalism: the basics [2019], 05) | |
| A reaction: [He cites Marx 'Critique of the Gotha Programme'] I would guess that this practice is not abnormal in old traditional villages, though a community would be tempted to reward highly a very successful member. |
| 22829 | Allowing defamatory speech is against society's interests, by blurring which people are trustworthy [Charvet] |
| Full Idea: The argument for restricting defamatory speech is that unrestricted speech makes it impossible, or too difficult, to distinguish between those who deserve a trustworthy reputation and those who don't - a distinction in society's best interests. | |
| From: John Charvet (Liberalism: the basics [2019], 03) | |
| A reaction: A nice example of appeal to the common good, in opposition to the normal freedoms of liberalism. An example of the Prisoner's Dilemma. Should assertion of the common good of a group be a prime value of liberalism? |
| 22836 | 'Freedom from' is an empty idea, if the freedom is not from impediments to my desires [Charvet] |
| Full Idea: Berlin's distinction of 'freedom from' and 'freedom to' is worthless …because to say that I want to be free from something for absolutely no reason makes no sense. Unfreedom is being blocked from what I want to do, which ceases if I no longer want it. | |
| From: John Charvet (Liberalism: the basics [2019], 07) | |
| A reaction: [compressed] The government could guarantee us against attacks by albatrosses, but we would hardly have a national holiday to celebrate the freedom. Still, there is freedom from incoming troubles, and freedom to output things. |
| 22837 | Positive freedom can lead to coercion, if you are forced to do what you chose to do [Charvet] |
| Full Idea: Berlin saw positive freedom as a justification for illiberal coercion. If I am positively free only in doing X, then if I am forced to do X, I will still be free. | |
| From: John Charvet (Liberalism: the basics [2019], 07) | |
| A reaction: I suppose Berlin is thinking of Russian farmers, who wanted to farm, but then found they were forced to do what they were going to do anyway. It's better than being forced to do what you didn't want to do. Forcing clearly isn't freedom. |
| 22844 | First level autonomy is application of personal values; second level is criticising them [Charvet] |
| Full Idea: First level autonomy is being able to apply one's scheme of values to one's actions and life; second level autonomy is being able to subject those values to critical evaluation. | |
| From: John Charvet (Liberalism: the basics [2019], 10) | |
| A reaction: Charvet sees this as a key issue for liberalism. How do you treat citizens who cannot advance beyond the first level? He mentions the elitism of Plato's Republic that results. |
| 22840 | Mere equality, as in two trees being the same height, has no value at all [Charvet] |
| Full Idea: That the relation of equality might be considered a value in itself is an absurdity. Would the equality of blinding the only sighted person in a blind society be good? Is it inherently good that two trees are the same height? This is nonsense. | |
| From: John Charvet (Liberalism: the basics [2019], 08) | |
| A reaction: He cites Temkin 1993 as defending the blinding example! Obviously equality is only possible in certain respects (though electrons might be equal in all respects). So the point is to identify the important respects. The rest is rhetoric. |
| 22843 | Inequalities are worse if they seem to be your fault, rather than social facts [Charvet] |
| Full Idea: Inequality is worse in a meritocracy than in a stratified society, because everyone enjoys a formal equality of status and your position in the social order is due to your merit or lack of merit, so you have only yourself to blame for being at the bottom. | |
| From: John Charvet (Liberalism: the basics [2019], 10) | |
| A reaction: This is the simple point that it is worse to lack some good if you might have possessed it, rather than it being entirely out of reach. It also makes the false assumption that people are largely responsible for their merit or lack of it (ignoring luck). |
| 22845 | Money allows unlimited inequalities, and we obviously all agree to money [Charvet] |
| Full Idea: The introduction of money allows people to accumulate wealth without limit. Since money only works through everyone's agreement …everyone can be taken to have agreed to the consequences of money in the unequal distribution of wealth. | |
| From: John Charvet (Liberalism: the basics [2019], 11) | |
| A reaction: [Locke] Presumably large inequalities of possessions and territory were possible before money, but there was at least an upper limit. The current owner of Amazon may end up with more wealth than the whole of the rest of humanity combined. |
| 22823 | The rule of law is mainly to restrict governments [Charvet] |
| Full Idea: The rule of law is directed at the restriction of the power of governments as much, if not more, then the power of private individuals. | |
| From: John Charvet (Liberalism: the basics [2019], 02) | |
| A reaction: The more powerful you are the more restricting is the rule of law. Every government is tempted to change the law to expand its powers. The UK government has just legislated to restrict public demonstrations. Law is the people's weapon against autocrats. |
| 22825 | The 1689 Bill of Rights denied the monarch new courts, or the right to sit as judge [Charvet] |
| Full Idea: The 1689 Bill of Rights said the monarch could not create new courts of law, or act as a judge at law. | |
| From: John Charvet (Liberalism: the basics [2019], 02) | |
| A reaction: The background was the abolition of the court of Star Chamber in 1641, which had been secret, severe, and controlled by the monarch. Is it possible to create a new type of court, or are we stuck with the current ones? |
| 22826 | From 1701 only parliament could remove judges, whose decisions could not be discussed [Charvet] |
| Full Idea: In 1701 UK judges were given secure tenure, being removable only by parliament which at the same time undertook to follow a convention not to discuss particular judicial decisions. | |
| From: John Charvet (Liberalism: the basics [2019], 02) | |
| A reaction: In recent years the UK Daily Mail published the pictures of three judges, and labelled them 'traitors' because of their verdict about leaving the European Union. |
| 22827 | Justice superior to the rule of law is claimed on behalf of the workers, or the will of the nation [Charvet] |
| Full Idea: Communist leaders justify themselves as the embodiment of the people's will as workers, and fascist leaders as expressing the will of the nation. Both believe their policies contain a superior justice on this basis. | |
| From: John Charvet (Liberalism: the basics [2019], 02) | |
| A reaction: [compressed] A neat summary of why the rule of law might be rejected (other than by simple tyrrany justified only by force). In modern democracies recent right-wing governments have pushed back the law and attacked justice on this basis. |
| 22828 | The rule of law mainly benefits those with property and liberties [Charvet] |
| Full Idea: A rule of law regime will primarily benefit those possessing property and liberty rights. | |
| From: John Charvet (Liberalism: the basics [2019], 02) | |
| A reaction: Important. It's no good fighting for the law if the law doesn't protect what you have got, or if you have got nothing to protect. Important steps must precede assertion of the rule of law. |
| 22832 | Welfare is needed if citizens are to accept the obligations of a liberal state [Charvet] |
| Full Idea: The welfare state provides the background conditions under which it is reasonable to expect one's fellow citizens to commit to liberal principles of interaction, even if those conditions can only be achieved through a degree of compulsion. | |
| From: John Charvet (Liberalism: the basics [2019], 05) | |
| A reaction: You cannot expect people to accept the role of 'free' citizen if that is likely to result in swift misery. A liberal state will only command loyalty if it has a safety net. Fully committed liberalism implies modest socialism. |
| 22173 | Galileo refuted the Aristotelian theory that heavier objects fall faster [Okasha] |
| Full Idea: Galileo's most enduring contribution lay in mechanics, where he refuted the Aristotelian theory that heavier bodies fall faster than lighter. | |
| From: Samir Okasha (Philosophy of Science: Very Short Intro (2nd ed) [2016], 2) | |
| A reaction: This must the first idea in the theory of mechanics, allowing mathematical treatment and accurate comparisons. |
