20186 | Unlike knowledge, wisdom cannot be misused [Zagzebski] |
Full Idea: A distinctive mark of wisdom is that it cannot be misused, whereas knowledge surely can be misused. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], I 1.2) | |
A reaction: She will argue, with Aristotle, that this is because wisdom (and maybe 'true' knowledge) must include 'phronesis' (practical wisdom), which is the key to all the virtues, intellectual and moral. This idea is striking, and obviously correct. |
19694 | Wisdom is the property of a person, not of their cognitive state [Zagzebski, by Whitcomb] |
Full Idea: Zagzebski takes wisdom as literally properties of persons, not persons' cognitive states. | |
From: report of Linda Trinkaus Zagzebski (Virtues of the Mind [1996], p.59-60) by Dennis Whitcomb - Wisdom 'Twofold' | |
A reaction: Not sure about this. Zagzebski uses this idea to endorse epistemic virtue. But knowledge and ignorance are properties of persons too. There can be, though, a precise mental state involved in knowledge, but not in wisdom. |
16943 | 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. |
6806 | Do not multiply entities beyond necessity [William of Ockham] |
Full Idea: Do not multiply entities beyond necessity. | |
From: William of Ockham (works [1335]) | |
A reaction: This is the classic statement of Ockham's Razor, though it is not found in his printed works. It appears to be mainly aimed at Plato's Theory of Forms. It is taken to refer to types of entities, not numbers. One seraph is as bad as a hundred. |
20221 | Precision is only one of the virtues of a good definition [Zagzebski] |
Full Idea: Precision is but one virtue of a definition, one that must be balanced against simplicity, elegance, conciseness, theoretical illumination, and practical usefulness. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], III 2.1) | |
A reaction: Illumination looks like the dream virtue for a good definition. Otherwise it is just ticked as accurate and stowed away. 'True justified belief' is a very illuminating definition of knowledge - if it is right. But it's not very precise. |
20220 | Objection by counterexample is weak, because it only reveals inaccuracies in one theory [Zagzebski] |
Full Idea: Objection by counterexample is the weakest sort of attack a theory can undergo. Even when the objection succeeds, it shows only that a theory fails to achieve complete accuracy. It does not distinguish among the various rival theories. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], III 2.1) | |
A reaction: Typically counterexamples are used to refute universal generalisations (i.e. by 'falsification'), but canny theorists avoid those, or slip in a qualifying clause. Counterexamples are good for exploring a theory's coverage. |
16949 | 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) |
16939 | 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. |
16948 | 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'. |
16945 | 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. |
22132 | Species and genera are individual concepts which naturally signify many individuals [William of Ockham] |
Full Idea: In his mature nominalism, species and genera are identified with certain mental qualities called concepts or intentions of the mind. Ontologically they are individuals too, like everthing else, ...but they naturally signify many different individuals. | |
From: William of Ockham (works [1335]), quoted by Claude Panaccio - William of Ockham p.1056 | |
A reaction: 'Naturally' is the key word, because the concepts are not fictions, but natural responses to encountering individuals in the world. I am an Ockhamist. |
20188 | Modern epistemology is too atomistic, and neglects understanding [Zagzebski] |
Full Idea: There are complaints that contemporary epistemology is too atomistic, and that the value of understanding has been neglected. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], I 2) | |
A reaction: This is because of the excessive influence of logic in contemporary analytic philosophy, which has to reduce knowledge to K(Fa), rather than placing it in a human context. |
20223 | Epistemology is excessively atomic, by focusing on justification instead of understanding [Zagzebski] |
Full Idea: The present obsession with justification and the neglect of understanding has resulted in a feature of epistemology already criticised by several epistemologists: its atomism. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], III 2.2) | |
A reaction: All analytic philosophy has become excessively atomic, because it relies too heavily on logic for its grounding and rigour. There are other sorts of rigour, such as AI, peer review, programming. Or rigour is an idle dream. |
20217 | Truth is valuable, but someone knowing the truth is more valuable [Zagzebski] |
Full Idea: Of course we value the truth, but the value we place on knowledge is more than the value of the truth we thereby acquire. …It also involves a valuabe relation between the knower and the truth. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], III 1) | |
A reaction: Hard to assess this. I take truth to be a successful relationship between a mind and a fact. Knowledge needs something extra, to avoid lucky true beliefs. Does a truth acquire greater and greater value as more people come to know it? Doubtful. |
20191 | Some beliefs are fairly voluntary, and others are not at all so [Zagzebski] |
Full Idea: My position is that beliefs, like acts, arrange themselves on a continuum of degrees of voluntariness, ranging from quite a bit to none at all. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], I 4.2) | |
A reaction: I'm sure we have no idea how we came to hold many of our beliefs, and if we see a cat, nothing seems to intervene between the seeing and the believing. But if you adopt a religion, believing its full creed is a big subsequent effort. |
20222 | Knowledge either aims at a quantity of truths, or a quality of understanding of truths [Zagzebski] |
Full Idea: Getting knowledge can be a matter either of reaching more truths or of gaining understanding of truths already believed. So it may be a way of increasing either the quality of true belief (cognitive contact with reality) or the quantity. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], III 2.1) | |
A reaction: I'm not sure how one would increase understanding of currently believed truths if it didn't involve adding some new truths to the collection. There is only the discovery of connections or structures, but those are new facts. |
20225 | For internalists Gettier situations are where internally it is fine, but there is an external mishap [Zagzebski] |
Full Idea: In internalist theories the grounds for justification are accessible to the believer, and Gettier problems arise when there is nothing wrong with the internally accessible aspects of the situation, but there is a mishap inaccessible to the believer. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], III 3.1) | |
A reaction: I'm sure we could construct an internal mishap which the believer was unaware of, such as two confusions of the meanings of words cancelling one another out. |
20226 | Gettier problems are always possible if justification and truth are not closely linked [Zagzebski] |
Full Idea: As long as the concept of knowledge closely connects the justification component and the truth component but permits some degree of independence between them, justified true belief will never be sufficient for knowledge. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], III 3.1) | |
A reaction: Out of context this sounds like an advertisement for externalism. Or maybe it just says we have to live with Gettier threats. Zagzebski has other strategies. |
20228 | We avoid the Gettier problem if the support for the belief entails its truth [Zagzebski] |
Full Idea: The way to avoid the Gettier problem is to define knowledge in such a way that truth is entailed by the other component(s) of the definition. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], III 3.1) | |
A reaction: Thus she defines virtuous justification as being successful, as virtues tend to be. This smacks of cheating. Surely we can be defeated in a virtuous way? If the truth is entailed then of course Gettier can be sent packing. |
20227 | Gettier cases arise when good luck cancels out bad luck [Zagzebski] |
Full Idea: The procedure for generating Gettier cases involves 'double luck': an instance of good luck cancels out an instance of bad luck. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], III 3.2) | |
A reaction: You can end up with the right answer in arithmetic if you make two mistakes rather than one. I'm picturing a life of one blundering error after another, which to an outsider seems to be going serenely well. |
20194 | Intellectual virtues are forms of moral virtue [Zagzebski] |
Full Idea: I argue that intellectual virtues are forms of moral virtue. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II Intro) | |
A reaction: This contrasts with Sosa, who seems to think intellectual virtues are just the most efficient ways of reaching the truth. I like Zabzebski's approach a lot, though we are in a very small minority. I love her book. We have epistemic and moral duties. |
20206 | Intellectual and moral prejudice are the same vice (and there are other examples) [Zagzebski] |
Full Idea: Maybe the intellectual and the moral forms of prejudice are the same vice, and this may also be true of other traits with shared names, such as humility, autonomy, integrity, perseverance, courage and trustworthiness. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 3.1) | |
A reaction: I find this claim very persuasive. The virtue of 'integrity' rather obviously embraces groups of both intellectually and morally desirable traits. |
20208 | We can name at least thirteen intellectual vices [Zagzebski] |
Full Idea: Some examples of intellectual vices: pride, negligence, idleness, cowardice, conformity, carelessness, rigidity, prejudice, wishful thinking, closed-mindedness, insensitivity to detail, obtuseness (in seeing relevance), and lack of thoroughness. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 3.1) | |
A reaction: There are thousands of vices for which we don't have names, like thinking about football when you should be doing metaphysics. The other way round is also a vice too, because football needs concentration. Discontent with your chair is bad too. |
20210 | A reliable process is no use without the virtues to make use of them [Zagzebski] |
Full Idea: It is not enough that a process is reliable; a person will not reliably use such a process without certain virtues. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 4.1.2) | |
A reaction: This is a point against Sosa's reliabilist account of virtues. Of course, all theories of epistemic justification (or of morality) will fail if people can't be bothered to implement them. |
20215 | A justified belief emulates the understanding and beliefs of an intellectually virtuous person [Zagzebski] |
Full Idea: A justified belief is what a person who is motivated by intellectual virtue, and who has the understanding of his cognitive situation a virtuous person would have, might believe in like circumstances. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 6.1) | |
A reaction: This is a whole-hearted definition of justification in terms of a theory of intellectual virtues. Presumably this would allow robots to have justified beliefs, if they managed to behave the way intellectually virtuous persons would behave. |
20187 | Epistemic perfection for reliabilism is a truth-producing machine [Zagzebski] |
Full Idea: Just as a utility-calculating machine would be the ideal moral agent according to utilitarianism, a truth-producing machine would be the ideal epistemic agent according to reliabilism, | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], I 1.2) | |
A reaction: Love this one! For consequentialists a successful robot is morally superior to an average human being. The reliabilist dream is just something that churns out truths. But what is the role of these truths in subsequent life? |
16944 | 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. |
16941 | 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. |
16940 | 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. |
16933 | 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. |
16934 | 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. |
16938 | 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! |
8486 | 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. |
16947 | 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. |
20218 | The self is known as much by its knowledge as by its action [Zagzebski] |
Full Idea: It seems to me that the concept of the self is constituted as much by what we know as by what we do. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], III 1) | |
A reaction: People take pride in what they know, which indicates that it is of central importance to a person's nature. Hard to evaluate ideas such as this. |
20205 | The feeling accompanying curiosity is neither pleasant nor painful [Zagzebski] |
Full Idea: Most feelings are experienced as pleasant or painful, but it is not evident that they all are; curiosity may be one that is not. [note: 'curiosity' may not be the name of a feeling, but a feeling typically accompanies it] | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 3.1) | |
A reaction: If a machine generates a sliding scale from pain to pleasure, is there a neutral feeling at the midpoint, or does all feeling briefly vanish there? Not sure. |
16932 | 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'? |
20202 | Motives involve desires, but also how the desires connect to our aims [Zagzebski] |
Full Idea: A motive does have an aspect of desire, but it includes something about why a state of affairs is desired, and that includes something about the way my emotions are tied to my aim. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 2.6) | |
A reaction: It is standard usage that a 'motive' involves some movement towards achieving the desire, and not merely having the desire. I'd quite like to stand on top of Everest, but have absolutely no motivation to try to achieve it. |
20216 | Modern moral theory concerns settling conflicts, rather than human fulfilment [Zagzebski] |
Full Idea: Modern ethics generally considers morality much less a system for fulfilling human nature than a set of principles for dealing with individuals in conflict. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 7) | |
A reaction: Historically I associate this move with Hugo Grotius around 1620. He was a great legalist, and eudaimonist virtue ethics gradually turned into jurisprudence. The Enlightenment sought rules for resolving dilemmas. Liberalism makes fulfilment private. |
20193 | Moral luck means our praise and blame may exceed our control or awareness [Zagzebski] |
Full Idea: Because of moral luck, the realm of the morally praiseworthy / blameworthy is not indisputably within one's voluntary control or accessible to one's consciousness. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], I 4.2) | |
A reaction: [She particularly cites Thomas Nagel for this] It is a fact that we will be blamed (more strongly) when we have moral bad luck, but the question is whether we should be. It seems harsh, but you can't punish someone as if they had had bad luck. |
20199 | Nowadays we doubt the Greek view that the flourishing of individuals and communities are linked [Zagzebski] |
Full Idea: Modern moral philosophers have been considerably more skeptical than were the ancient Greeks about the close association between the flourishing of the individual and that of the community. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 2.2) | |
A reaction: I presume this is not just a change in fashion, but a reflection of how different the two societies are. In a close community with almost no privacy, flourishing individuals are good citizens. In the isolations of modern liberalism they may be irrelevant. |
20196 | Virtue theory is hopeless if there is no core of agreed universal virtues [Zagzebski] |
Full Idea: An analysis of virtue is hopeless unless we can assume that most of a selected list of traits count as virtues, in a way not strictly culture. ...These would include wisdom, courage, benevolence, justice, honesty, loyalty, integrity, and generosity. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 2.1) | |
A reaction: This requirement needs there to be a single core to human nature, right across the species. If we are infinitely flexible (as existentialists imply) then the virtues will have matching flexibility, and so will be parochial and excessively relative. |
20200 | A virtue must always have a corresponding vice [Zagzebski] |
Full Idea: It is important for the nature of virtue that it have a corresponding vice (or two, in the doctrine of the mean). Claustrophobia is not a vice not only because it is involuntary, but also because there is no corresponding virtue. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 2.3) | |
A reaction: Presumably attaining a virtue is an achievement, so we would expect a label for failure in the same field of endeavour. The failure is not purely negative, because bad things ensue if the virtue is not present. |
20201 | Eight marks distingush skills from virtues [Zagzebski, by PG] |
Full Idea: The difference between skills and virtues is that virtues must be enacted, are always desirable, can't be forgotten, and can be simulated, whereas skills are very specific, involve a technique, lack contraries, and lack intrinsic value. | |
From: report of Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 2.4) by PG - Db (ideas) | |
A reaction: [my summary of her II 2.4 discussion of the differences] She observes that Aristotle made insufficient effort to distinguish the two. It may be obscure to say that virtues go 'deeper' than skills, but we all know what is meant. 'Skills serve virtues'. |
20207 | Every moral virtue requires a degree of intelligence [Zagzebski] |
Full Idea: Being reasonably intelligent within a certain area of life is part of having almost any moral virtue. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 3.1) | |
A reaction: The fact that this bars persons of very limited intelligence from acquiring the Aristotelian virtues is one of the attractions of the Christian enjoinder to merely achieve 'love'. Anyone can have a warm heart. So is virtue elitist? |
20203 | Virtues are deep acquired excellences of persons, which successfully attain desire ends [Zagzebski] |
Full Idea: A virtue can be defined as 'a deep and enduring acquired excellence of a person, involving a characteristic motivation to produce a certain desired end and reliable success in bringing about that end'. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 2.7) | |
A reaction: She puts this in bold, and it is the culminating definition of a long discussion. It rather obviously fails to say anything about the nature of the end that is desired. Learning the telephone book off by heart seems to fit the definition. |
20214 | Virtue theory can have lots of rules, as long as they are grounded in virtues and in facts [Zagzebski] |
Full Idea: A pure virtue theory can have as many rules as you like as long as they are understood as grounded in the virtuous motivations and understanding of the nonmoral facts that virtuous agents possess. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 6.1) | |
A reaction: It is important, I think, to see that a virtue theorist does not have to be a particularist. |
20213 | We need phronesis to coordinate our virtues [Zagzebski] |
Full Idea: We need phronesis (practical wisdom) to coordinate the various virtues into a single line of action or line of thought leading up to an act or to a belief. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 5.2) | |
A reaction: If I have a conflicting virtue and vice in a single situation, something must make sure that the virtue dominates. That sounds more like Kant's 'good will' than like phronesis. |
20209 | For the virtue of honesty you must be careful with the truth, and not just speak truly [Zagzebski] |
Full Idea: It is not sufficient for honesty that a person tells whatever she happens to believe is the truth. An honest person is careful with the truth. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 3.2) | |
A reaction: Not sure about that. It matches what Aristotle says about courage, which also needs practical reason [phronesis]. But being sensitive and careful with truth seems to need other virtues. If total honesty is not a virtue, then is honesty a virtue at all? |
20197 | The courage of an evil person is still a quality worth having [Zagzebski] |
Full Idea: In the case of a courageous Nazi soldier, my position is that a virtue is worth having even in those cases in which it makes a person worse overall. | |
From: Linda Trinkaus Zagzebski (Virtues of the Mind [1996], II 2.2) | |
A reaction: A brave claim, which seems right. If a nasty Nazi reforms, they will at least have one good quality which can be put to constructive use. |
7375 | 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. |
16935 | 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. |
16936 | 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. |
16937 | 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. |
16942 | 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. |
19381 | The past has ceased to exist, and the future does not yet exist, so time does not exist [William of Ockham] |
Full Idea: Time is composed of non-entities, because it is composed of the past which does not exist now, although it did exist, and of the future, which does not yet exist; therefore time does not exist. | |
From: William of Ockham (works [1335], 6:496), quoted by Richard T.W. Arthur - Leibniz 7 'Nominalist' | |
A reaction: I've a lot of sympathy with this! I favour Presentism, so the past is gone and the future is yet to arrive. But we have no coherent concept of a present moment of any duration to contain reality. We are just completely bogglificated by it all. |
