1. Philosophy / G. Scientific Philosophy / 3. Scientism
Philosophy is continuous with science, and has no external vantage point [Quine]
     Full Idea: I see philosophy not as an a priori propaedeutic or groundwork for science, but as continuous with science. I see philosophy and science as in the same boat. …There is no external vantage point, no first philosophy.
     From: Willard Quine (Natural Kinds [1969], p.126)
     A reaction: Philosophy is generalisation. Science holds the upper hand, because it settles the subject-matter to be generalised.
6. Mathematics / A. Nature of Mathematics / 2. Geometry
Klein summarised geometry as grouped together by transformations [Quine]
     Full Idea: Felix Klein's so-called 'Erlangerprogramm' in geometry involved characterizing the various branches of geometry by what transformations were irrelevant to each.
     From: Willard Quine (Natural Kinds [1969], p.137)
7. Existence / C. Structure of Existence / 8. Stuff / a. Pure stuff
Mass terms just concern spread, but other terms involve both spread and individuation [Quine]
     Full Idea: 'Yellow' and 'water' are mass terms, concerned only with spread; 'apple' and 'square' are terms of divided reference, concerned with both spread and individuation.
     From: Willard Quine (Natural Kinds [1969], p.124)
     A reaction: Would you like some apple? Pass me that water. It is helpful to see that it is a requirement of 'individuation' that is missing from terms for stuff.
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / a. Dispositions
Once we know the mechanism of a disposition, we can eliminate 'similarity' [Quine]
     Full Idea: Once we can legitimize a disposition term by defining the relevant similarity standard, we are apt to know the mechanism of the disposition, and so by-pass the similarity.
     From: Willard Quine (Natural Kinds [1969], p.135)
     A reaction: I love mechanisms, but can we characterise mechanisms without mentioning powers and dispositions? Quine's dream is to eliminate 'similarity'.
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / d. Dispositions as occurrent
We judge things to be soluble if they are the same kind as, or similar to, things that do dissolve [Quine]
     Full Idea: Intuitively, what qualifies a thing as soluble though it never gets into water is that it is of the same kind as the things that actually did or will dissolve; it is similar to them.
     From: Willard Quine (Natural Kinds [1969], p.130)
     A reaction: If you can judge that the similar things 'will' dissolve, you can cut to the chase and judge that this thing will dissolve.
14. Science / A. Basis of Science / 3. Experiment
Science is common sense, with a sophisticated method [Quine]
     Full Idea: Sciences differ from common sense only in the degree of methodological sophistication.
     From: Willard Quine (Natural Kinds [1969], p.129)
     A reaction: Science is normal thinking about the world, but it is teamwork, with the bar set very high.
14. Science / C. Induction / 1. Induction
Induction relies on similar effects following from each cause [Quine]
     Full Idea: Induction expresses our hopes that similar causes will have similar effects.
     From: Willard Quine (Natural Kinds [1969], p.125)
     A reaction: Some top philosophers are also top teachers, and Quine was one of them, in his writings. He boils it down for the layman. Once again, he is pointing to the fundamental role of the similarity relation.
Induction is just more of the same: animal expectations [Quine]
     Full Idea: Induction is essentially only more of the same: animal expectation or habit formation.
     From: Willard Quine (Natural Kinds [1969], p.125)
     A reaction: My working definition of induction is 'learning from experience', but that doesn't disagree with Quine. Lipton has a richer account of different types of induction. Quine's point is that it rests on resemblance.
14. Science / C. Induction / 5. Paradoxes of Induction / a. Grue problem
Grue is a puzzle because the notions of similarity and kind are dubious in science [Quine]
     Full Idea: What makes Goodman's example a puzzle is the dubious scientific standing of a general notion of similarity, or of kind.
     From: Willard Quine (Natural Kinds [1969], p.116)
     A reaction: Illuminating. It might be best expressed as revealing a problem with sortal terms, as employed by Geach, or by Wiggins. Grue is a bit silly, but sortals are subject to convention and culture. 'Natural' properties seem needed.
15. Nature of Minds / C. Capacities of Minds / 7. Seeing Resemblance
General terms depend on similarities among things [Quine]
     Full Idea: The usual general term, whether a common noun or a verb or an adjective, owes its generality to some resemblance among the things referred to.
     From: Willard Quine (Natural Kinds [1969], p.116)
     A reaction: Quine has a nice analysis of the basic role of similarity in a huge amount of supposedly strict scientific thought.
To learn yellow by observation, must we be told to look at the colour? [Quine]
     Full Idea: According to the 'respects' view, our learning of yellow by ostension would have depended on our first having been told or somehow apprised that it was going to be a question of color.
     From: Willard Quine (Natural Kinds [1969], p.122)
     A reaction: Quine suggests there is just one notion of similarity, and respects can be 'abstracted' afterwards. Even the ontologically ruthless Quine admits psychological abstraction!
Standards of similarity are innate, and the spacing of qualities such as colours can be mapped [Quine]
     Full Idea: A standard of similarity is in some sense innate. The spacing of qualities (such as red, pink and blue) can be explored and mapped in the laboratory by experiments. They are needed for all learning.
     From: Willard Quine (Natural Kinds [1969], p.123)
     A reaction: This reasserts Hume's original point in more scientific terms. It is one of the undeniable facts about our perceptions of qualities and properties, no matter how platonist your view of universals may be.
Similarity is just interchangeability in the cosmic machine [Quine]
     Full Idea: Things are similar to the extent that they are interchangeable parts of the cosmic machine.
     From: Willard Quine (Natural Kinds [1969], p.134)
     A reaction: This is a major idea for Quine, because it is a means to gradually eliminate the fuzzy ideas of 'resemblance' or 'similarity' or 'natural kind' from science. I love it! Two tigers are same insofar as they are substitutable.
16. Persons / E. Rejecting the Self / 2. Self as Social Construct
The 'Kantian' self steps back from commitment to its social situation [Kymlicka]
     Full Idea: The 'Kantian' view of the self strongly defends the view that the self is prior to its socially given roles and relationships, and is free only if it is capable of holding these features of its social situation at a distance, and judging them by reason.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 6.3)
     A reaction: There is no correct answer here, because I am capable of Kantian distancing, and also capable of submersing myself in the social constructions around me. If society fosters rebellion (1810s, 1960s) then we become more Kantian.
19. Language / C. Assigning Meanings / 3. Predicates
Projectible predicates can be universalised about the kind to which they refer [Quine]
     Full Idea: 'Projectible' predicates are predicates F and G whose shared instances all do count, for whatever reason, towards confirmation of 'All F are G'. ….A projectible predicate is one that is true of all and only the things of a kind.
     From: Willard Quine (Natural Kinds [1969], p.115-6)
     A reaction: Both Quine and Goodman are infuriatingly brief about the introduction of this concept. 'Red' is true of all ripe tomatoes, but not 'only' of them. Hardly any predicates are true only of one kind. Is that a scholastic 'proprium'?
22. Metaethics / C. The Good / 1. Goodness / c. Right and good
Teleological theories give the good priority over concern for people [Kymlicka]
     Full Idea: Teleological theories take concern for the good (e.g. freedom or utility) as fundamental, and concern for people as derivative.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.4.a.ii)
     A reaction: There's a nice fundamental question with which to begin a discussion of value: which matters most - abstract values, or individual people? Placing a collective of people first (Stalinism?) seems to fall between them.
23. Ethics / C. Virtue Theory / 1. Virtue Theory / c. Particularism
Maybe the particularist moral thought of women is better than the impartial public thinking of men [Kymlicka]
     Full Idea: There is a significant strand of contemporary feminism which argues that we should take seriously women's different morality. ...The particularistic thought women employ is a better morality than the impartial thought men employ in the public sphere.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 7.3)
     A reaction: I had taken Particularism to be an offshoot of virtue theory, as promulgated by Jonathan Dancy. Evidently the influence of feminism is strong. Personally I think the world would be a better place if it was run by women.
23. Ethics / E. Utilitarianism / 1. Utilitarianism
One view says start with equality, and infer equal weight to interests, and hence maximum utility [Kymlicka]
     Full Idea: The first main argument for utilitarianism is that people matter equally, and hence each person's interests should be given equal weight, and hence morally right acts will maximise utility.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.4.a)
     A reaction: The point is that this starts from the aim of equality, and infers maximum utility as its consequence. Equality has a primitive value. Whenever you dig down to a primitive value in a theory, I just find myself puzzled. What can justify basic equality?
A second view says start with maximising the good, implying aggregation, and hence equality [Kymlicka]
     Full Idea: The second main argument for utilitarianism defines the right in terms of maximising the good, which leads to the utilitarian aggregation standard, which as a mere consequence treats people's interests equally.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.4.b)
     A reaction: This takes maximum good as a primitive, and arrives at equality as the way to achieve it. So which is more morally fundamental, a maximum of goodness, or human equality? Kymlicka says this idea is too impersonal.
Utilitarianism is not a decision-procedure; choice of the best procedure is an open question [Kymlicka]
     Full Idea: Utilitarianism is essentially a 'standard of rightness', not a 'decision-procedure'. ...It is an open question whether we should employ a utilitarian decision-procedure - indeed, this question itself is to be answered by examining its consequences.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.3.b)
     A reaction: The point is that the aim is to maximise happiness, and you might do that by just maximising baked bean consumption, and not even thinking about happiness. This idea is labelled 'indirect utilitarianism'. Happiness does seem to be a by-product.
24. Political Theory / A. Basis of a State / 2. Population / a. Human population
To maximise utility should we double the population, even if life somewhat deteriorates? [Kymlicka]
     Full Idea: Morally, should we double the population, even if it means reducing each person's welfare by almost half (since that will still increase overall utility)?
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.4.b)
     A reaction: [He cites Derek Parfit for this] The key word is 'almost', which ensures a small increase in overall utility. I think this is a particularly good objection to utilitarianism, which aims to maximise an abstraction called 'utility'.
24. Political Theory / A. Basis of a State / 4. Original Position / c. Difference principle
The difference principles says we must subsidise the costs of other people's choices [Kymlicka]
     Full Idea: The difference principle does not make any distinction between chosen and unchosen inequalities, ....but the difference principle requires that some people subsidise the costs of other people's choices.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 3.3.b.2)
     A reaction: We do this in education, allowing people to study things in which we can see little point. We subsidise public ceremonies which strike us as ridiculous.
24. Political Theory / B. Nature of a State / 2. State Legitimacy / c. Social contract
Social contract theories are usually rejected because there never was such a contract [Kymlicka]
     Full Idea: Social contract theories have all been subjected to the same criticism - that there never was such a state of nature, or such a contract. Hence neither citizens nor government are bound by it. Contracts only create obligations if they are actually agreed.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 3.3)
     A reaction: Even if they have been agreed in the past, why should subsequent generations be bound to them? Modern Germans aren't bound by their grandparents' oaths of allegiance to fascism.
24. Political Theory / D. Ideologies / 4. Social Utilitarianism
Utilitarianism is no longer a distinctive political position [Kymlicka]
     Full Idea: Modern utilitarianism, despite its radical heritage, no longer defines a distinctive political position.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.6)
     A reaction: This is his final sentence on the topic. I suppose utilitarianism exists as a moral theory at too high a level of generality to count as a political theory.
The quest of the general good is partly undermined by people's past entitlements [Kymlicka]
     Full Idea: The existence of past entitlements on the part of particular people partially pre-empts, or constrains, the utilitarian quest to maximise the general good.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.3.a)
     A reaction: In other words, there is never a clean slate in politics (except in some hideously violent revolution). You might be able to justify to someone a withdrawal of their past entitlements. E.g. confiscating a stolen painting that was bought in ignorance.
We shouldn't endorse preferences which reject equality, and show prejudice and selfishness [Kymlicka]
     Full Idea: Equality should enter into the very formation of our preferences. ....Prejudiced and selfish preferences should be excluded from the start, for they already reflect a failure to show equal consideration.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.5.b)
     A reaction: This is meant to block utilitarian summing of preferences like racism, but it feels like a rather desperate attempt to get righteous liberal values in at the beginning, where they can't be questioned. How can you justify equal respect and treatment?
Using utilitarian principles to make decisions encourages cold detachment from people [Kymlicka]
     Full Idea: Acting directly on utilitarian grounds is counter-productive, for it encourages a contingent and detached attitude towards what should be whole-hearted personal and political commitments.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.7)
     A reaction: I've always seen this as an objection to utilitarianism, but I now see that it is only an objection to the decision procedure. We should be warm-hearted and committed, in the knowledge that this will increase benefits to all. Hm. A bit schizoid.
Utilitarianism is irrational if it tells you to trade in your rights and resources just for benefits [Kymlicka]
     Full Idea: Utilitarianism is an irrational choice, for it is rational to ensure your basic rights and resources are protected, even if you thereby lessen your chance of receiving benefits above and beyond the basic goods that you seek to protect.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 3.3)
     A reaction: [He's discussing Rawls] Utilitarians would obviously respond to this by saying that the rights and resources are needed to protect future benefits, so it would be short-termism to trade them in now.
24. Political Theory / D. Ideologies / 6. Liberalism / b. Liberal individualism
Modern liberalism has added personal privacy to our personal social lives [Kymlicka]
     Full Idea: Modern liberalism is concerned not only to protect the private sphere of social life, but also to carve out a realm within the private sphere where individuals can have privacy.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 7.2.b)
     A reaction: Interestingly, he associates this development with the romantic movement, which designated social interaction as public and political, creating a need for true privacy. Privacy is the blessing and blight of the modern world.
24. Political Theory / D. Ideologies / 6. Liberalism / d. Liberal freedom
Liberalism tends to give priority to basic liberties [Kymlicka]
     Full Idea: One way of differentiating liberalism is that it gives priority to the basic liberties.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 3.1.b)
     A reaction: [He is citing Rawls for this] This is not the same as extreme libertarianism, which makes liberty the only priority. The issue would be over which liberties count as 'basic'. Taxation would be a good test case.
24. Political Theory / D. Ideologies / 6. Liberalism / e. Liberal community
Liberals are not too individualistic, because people recognise and value social relations [Kymlicka]
     Full Idea: It is alleged that liberals fail to recognise that people are naturally social or communal. …But liberals believe that people form and join social relations in which they come to understand and pursue the good.
     From: Will Kymlicka (Liberal Individualism and Liberal Neutrality [1989], Conc)
     A reaction: This is particulary aimed at communitarians, who see liberalism as based on a distorted concept of people as isolated beings. Personally I am beginning to shift my views from Aristotelian communitarianism to modern liberalism, so I like this idea.
24. Political Theory / D. Ideologies / 6. Liberalism / g. Liberalism critique
Marxists say liberalism is unjust, because it allows exploitation in the sale of labour [Kymlicka]
     Full Idea: The fundamental flaw of liberal justice, Marxists claim, is that it licences the continuation of the worker by the capitalist, since it licences the buying and selling labour.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 5.2.a)
     A reaction: I can't see that all sale of labour is exploitation, if (for example) the wage paid was extremely high (maybe even higher than the employer's wage, which is possible). So exploitation involves something more.
24. Political Theory / D. Ideologies / 7. Communitarianism / a. Communitarianism
The 'Kantian' view of the self misses the way it is embedded or situated in society [Kymlicka]
     Full Idea: Communitarians believe that the 'Kantian' view of the self is false, because it ignores the fact that the self is 'embedded' or 'situated' in existing social practices, so that we cannot always stand back and opt out of them.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 6.3)
     A reaction: [Hegel and Charles Taylor 1979 seem to be the sources for this] I have several times been told that I am so typical of the culture I arose in that it is almost comical. This was quite disconcerting, but I got used to it, and now I love it.
Communitarians say we should pay more attention to our history [Kymlicka]
     Full Idea: Communitarians like to say that political theory should pay more attention to the history of each culture.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 6.4.c)
     A reaction: I like this. Kylicka says communitarians tend not to do this, partly because history might reveal an unpleasant basis for present society (such as English country house life benefiting from slavery). The ignorance of history among politicians appals me.
24. Political Theory / D. Ideologies / 7. Communitarianism / b. Against communitarianism
Communitarian states only encourage fairly orthodox ideas of the good life [Kymlicka]
     Full Idea: A communitarian state can and should encourage people to adopt conceptions of the good that conform to the community's way of life, while discouraging conceptions of the good that conflict with it.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 6.2)
     A reaction: This is the conservative aspect of communitarianism which many people (notably liberals) find uncongenial. This conservatism is implicit in Aristotle's account of virtue. I have become more conservative to accommodate it.
25. Social Practice / A. Freedoms / 1. Slavery
If everyone owned himself, that would prevent slavery [Kymlicka]
     Full Idea: The best way to prevent enslavement of one person to another is to give each person ownership over himself.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 4.2.c)
     A reaction: [The idea comes from Nozick, but Kymlicka is assessing how it should be understood] The best way to block any social evil like slavery is to make it unthinkable. Legislation is second best. Presumably I could sell myself into slavery (like Faust)?
25. Social Practice / A. Freedoms / 4. Free market
Libertarians like the free market, but they also think that the free market is just [Kymlicka]
     Full Idea: Not everyone who favours the free market is a libertarian, for they do not all share the libertarian view that the free market is inherently just.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 4.1.a)
     A reaction: Illuminating. It would appear that exploitation is possible within a strictly free market, so it seems unlikely that free markets are inherently just (unless you don't acknowledge that 'exploitation' is wrong).
25. Social Practice / A. Freedoms / 5. Freedom of lifestyle
The most valuable liberties to us need not be the ones with the most freedom [Kymlicka]
     Full Idea: Different liberties promote different interests for many different reasons, and there is no reason to assume that the liberties which are most valuable to us are the ones with the most freedom.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.4.a.iii)
     A reaction: As I grow older I come more and more to think that freedom is overvalued. But have you tried the other thing? We complacently take huge freedoms for granted. Be passionate about fundamental freedoms, and relaxed about the rest.
25. Social Practice / A. Freedoms / 6. Political freedom
Ancient freedom was free participation in politics, not private independence of life [Kymlicka]
     Full Idea: The liberty of the ancients was their active participation in the exercise of political power, not the peaceful enjoyment of personal independence.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 7.2.a)
     A reaction: Interesting. It takes a feat of imagination to grasp a world where the desire for freedom to sit at home and compile a database of philosophical ideas never even crossed anyone's mind.
25. Social Practice / B. Equalities / 2. Political equality
Equal opportunities seems fair, because your fate is from your choices, not your circumstances [Kymlicka]
     Full Idea: The ideology of equal opportunity seems fair to many people in our society because it ensures that people's fate is determined by their choices, rather than their circumstances.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 3.2)
     A reaction: Is it that we surmise that people have 'free will', and then engineer a situation where it can be exercised? Is it that the rest of us don't want to feel guilty when someone else's life goes awry (because it was 'their fault')?
Equal opportunity arbitrarily worries about social circumstances, but ignores talents [Kymlicka]
     Full Idea: The prevailing view [of equal opportunity] only recognises differences in social circumstances, while ignoring differences in natural talents (or treating them as if they were a choice). This is an arbitrary limit on the theory's central intuition.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 3.2)
     A reaction: Of course we (society) can do a lot about your social circumstances, but very little about your talents, other than to develop them or thwart them. Talented children need more than mere 'opportunity'.
25. Social Practice / B. Equalities / 3. Legal equality
Marxists say justice is unneeded in the truly good community [Kymlicka]
     Full Idea: Marxists believe that justice, far from being the first virtue of social institutions, is something that the truly good community has no need for.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 5.1)
     A reaction: This seems to imply that in the truly good community there are nothing but truly good individuals, which is taking social determinism to its limits. Are all the citizens of a bad community inherently bad?
25. Social Practice / C. Rights / 1. Basis of Rights
The Lockean view of freedom depends on whether you had a right to what is restricted [Kymlicka]
     Full Idea: The Lockean camp defines freedom in terms of the exercise of our rights. Whether or not a restriction decreases our freedom depends on whether or not we had a right to do the restricted thing.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 2.4.a.iii)
     A reaction: My first instinct is to be sympathetic to this, since a detached and general notion of 'freedom' strikes me as suspect. He offers the rival 'Spenserian' view of freedom as just having the choice.
25. Social Practice / D. Justice / 1. Basis of justice
Justice corrects social faults, but also expresses respect to individuals as ends [Kymlicka]
     Full Idea: Justice is more than a remedial virtue. It does remedy defects in social co-ordination, ...but it also expresses the respect individuals are owed as ends in themselves, not as mean's to someone's good, or even to the common good.
     From: Will Kymlicka (Contemporary Political Philosophy (1st edn) [1990], 5.1)
     A reaction: That is, I take it, that justice operates at two different levels in our theoretical social thinking.
26. Natural Theory / B. Natural Kinds / 1. Natural Kinds
Quine probably regrets natural kinds now being treated as essences [Quine, by Dennett]
     Full Idea: The concept of natural kinds was reintroduced by Quine, who may now regret the way it has become a stand-in for the dubious but covertly popular concept of essences.
     From: report of Willard Quine (Natural Kinds [1969]) by Daniel C. Dennett - Consciousness Explained 12.2 n2
     A reaction: He is right that Quine would regret it, and he is right that we can't assume that there are necessary essences just because there seem to be stable natural kinds, but personally I am an essentialist, so I'm not that bothered.
If similarity has no degrees, kinds cannot be contained within one another [Quine]
     Full Idea: If similarity has no degrees there is no containing of kinds within broader kinds. If colored things are a kind, they are similar, but red things are too narrow for a kind. If red things are a kind, colored things are not similar, and it's too broad.
     From: Willard Quine (Natural Kinds [1969], p.118)
     A reaction: [compressed] I'm on Quine's side with this. We glibly talk of 'kinds', but the criteria for sorting things into kinds seems to be a mess. Quine goes on to offer a better account than the (diadic, yes-no) one rejected here.
Comparative similarity allows the kind 'colored' to contain the kind 'red' [Quine]
     Full Idea: With the triadic relation of comparative similarity, kinds can contain one another, as well as overlapping. Red and colored things can both count as kinds. Colored things all resemble one another, even though less than red things do.
     From: Willard Quine (Natural Kinds [1969], p.119)
     A reaction: [compressed] Quine claims that comparative similarity is necessary for kinds - that there be some 'foil' in a similarity - that A is more like C than B is.
26. Natural Theory / B. Natural Kinds / 3. Knowing Kinds
You can't base kinds just on resemblance, because chains of resemblance are a muddle [Quine]
     Full Idea: If kinds are based on similarity, this has the Imperfect Community problem. Red round, red wooden and round wooden things all resemble one another somehow. There may be nothing outside the set resembling them, so it meets the definition of kind.
     From: Willard Quine (Natural Kinds [1969], p.120)
     A reaction: [ref. to Goodman 'Structure' 2nd 163- , which attacks Carnap on this] This suggests an invocation of Wittgenstein's family resemblance, which won't be much help for natural kinds.
26. Natural Theory / D. Laws of Nature / 4. Regularities / a. Regularity theory
It is hard to see how regularities could be explained [Quine]
     Full Idea: Why there have been regularities is an obscure question, for it is hard to see what would count as an answer.
     From: Willard Quine (Natural Kinds [1969], p.126)
     A reaction: This is the standard pessimism of the 20th century Humeans, but it strikes me as comparable to the pessimism about science found in Locke and Hume. Regularities are explained all the time by scientists, though the lowest level may be hopeless.
