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. |
18405 | A 'teepee' argument has several mutually supporting planks to it [Cappelen/Dever] |
Full Idea: In a 'teepee' argument, a number of argumentative planks intersupport each other. No plank is sufficiently strong to establish the position, but each lends credibility to the others because there is the appearance of a unified phenomenon. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 01.5) | |
A reaction: To attack it, they say, you have to identify the separate planks of the argument. It is a moot point whether the teepee might be so imprecise that it is better described as 'coherence'. There is a background support, as well as the planks. |
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. |
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. |
18422 | Prioprioception focuses on your body parts, not on your self, or indexicality [Cappelen/Dever] |
Full Idea: Proprioception is not focused single-mindedly on the self, but is focused on a number of objects - the component bodily parts that belong to the self. There is no obvious need for a concept of the self, or of indexicality. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 07.2) |
18425 | We can acquire self-knowledge with mirrors, not just with proprioception and introspection [Cappelen/Dever] |
Full Idea: Imagine a being that learns everything about itself by watching itself in mirrors, rather than by proprioception and introspection. Surely it can get wet in a storm, even though allegedly distinctive routes of self-knowledge are not available to it? | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 09.3) | |
A reaction: [compressed] |
18421 | Proprioception is only immune from error if you are certain that it represents the agent [Cappelen/Dever] |
Full Idea: The guarantee of immunity from error in prioprioception is only as strong as the guarantee that proprioception only ever represents the proprioceiving agent. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 07.1) | |
A reaction: This is part of an interesting and sustained attack on the idea that self-knowledge is immune from error. They are thinking of science-fictiony situations where I am wired up to experience your leg movement. My experiences usually track me, that's all. |
18419 | Folk Functionalism is a Ramsification of our folk psychology [Cappelen/Dever] |
Full Idea: According to Folk Functionalism, mental states are theoretically defined by Ramsifying on our folk-psychological theory. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 06.2) |
18404 | It is assumed that indexical content is needed to represent the perspective of perception [Cappelen/Dever] |
Full Idea: Because our perceptual states typically represent the world as seen from a perspective, it is sometimes thought that some distinctively indexical kind of content is needed to characterise those states. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 01.4) | |
A reaction: They are summarising this view precisely so that they can oppose it, and I think they are right. |
18426 | All information is objective, and purely indexical information is not much use [Cappelen/Dever] |
Full Idea: Fundamentally, all information is objective information. ...[176] What we want is fully portable information, and information that co-ordinates on the world, rather than on us, is best suited for the task. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 10) | |
A reaction: I agree entirely with their thesis. We just pick up information about ourselves, such as who and where we are, which is just like equivalent information about other people. It is isn't a special type of information. |
18428 | You don't remember your house interior just from an experienced viewpoint [Cappelen/Dever] |
Full Idea: When you recall the look of the inside of your house ....where things are relative to one another is what persists in memory, not where they were relative to you when seen. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 10) | |
A reaction: This seems to be a very telling example, though you could postulate some system which converts perspectival input into objective information. But why bother? We seek objective information, not perspectives. |
18429 | Our beliefs and desires are not organised around ourselves, but around the world [Cappelen/Dever] |
Full Idea: Our view on the world is not primarily a view from a perspective. Our beliefs and desires are not organized around us. They are instead organized around the world itself. Our view is a view from everywhere. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 10) | |
A reaction: Slipping in the claim that our desires are also organised around the world is not quite as persuasive as the claim about beliefs. If you want to draw a freehand straight line, focus on the far end of it. The world will guide your hand. |
18427 | If some of our thought is tied to its context, it will be hard to communicate it [Cappelen/Dever] |
Full Idea: It is bad news if some of our contents are essentially tied to particular contexts. ...If information needs to be assessed relative to some ur-context, later recipients won't know what to do with it. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 10) |
18407 | Indexicality is not significantly connected to agency [Cappelen/Dever] |
Full Idea: There are no interesting or distinctive explanatory connections between indexicality and agency. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 01.8) |
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'? |
18413 | Fregeans can't agree on what 'senses' are [Cappelen/Dever] |
Full Idea: There is little agreement among Fregeans about what senses are. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 04.5) | |
A reaction: I don't take this to be sufficient grounds for dismissing Fregean senses. When we look into the workings of the linguistic mind, there seems little prospect of clarity or agreement. |
18417 | Possible worlds accounts of content are notoriously coarse-grained [Cappelen/Dever] |
Full Idea: Possible worlds accounts of content are notoriously coarse-grained. They fail to distinguish between logical or mathematical truths, ..between metaphysical equivalences, ..between coreferentials, ..and between indexicals and non-indexicals. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 05.5) | |
A reaction: [A nice summary, very compressed] |
18408 | Indexicals are just non-constant in meaning, and don't involve any special concepts [Cappelen/Dever] |
Full Idea: Once the non-constant characters of expressions has been characterised, there is no further need for additional devices like 'first-person concepts' or 'demonstrative concepts'. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 01.7) | |
A reaction: This seems to me to be a wonderfully liberating attack on this issue. There is a kind of creepy mysticism that has been allowed to accrue around indexicals, and it's nonsense. |
18414 | Fregeans say 'I' differs in reference, so it must also differ in sense [Cappelen/Dever] |
Full Idea: Fregeans tend to treat as a fundamental tenet that sense determines reference; same sense, same reference. From that it follow trivially that indexicals don't have the same sense: different uses of 'I' have different referents, so sense must differ. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 04.6) | |
A reaction: Interesting. Since it seems implausible that 'I' is profoundly different when two people use it, this seems to be a strong argument against Frege's distinction. But I rather like Frege's distinction, while being sceptical about 'I', so I'm baffled.... |
18423 | All indexicals can be expressed non-indexically [Cappelen/Dever] |
Full Idea: Whatever can be expressed indexically could be expressed by non-indexical means. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 08.1) | |
A reaction: This is the best summary of the thesis of their book. Indexicality in non-essential. |
18406 | The basic Kaplan view is that there is truth-conditional content, and contextual character [Cappelen/Dever] |
Full Idea: In what we label 'Basic Kaplanianism', each of the sentences 'Smith is happy' and 'I am happy', as uttered by Smith, has two levels of meaning. The 'content' is a truth-conditional representation. The 'character' is a function from contexts to contents. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 01.6) | |
A reaction: They give this as a minimal and plausible account of the situation, without reading huge significance into the indexical. I'm inclined to see the situation in terms of the underlying proposition containing both ingredients. |
18411 | It is proposed that a huge range of linguistic items are context-sensitive [Cappelen/Dever] |
Full Idea: An enormous amount has been written about whether 'all', 'know', 'might', 'delicious', 'good', 'if, then', 'and', 'red', 'just', 'justified', 'probable', 'local', 'ready', and 'left-right' are context-sensitive. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 02.3) | |
A reaction: The clearest way to approach these things is ask what the (informal) domain of quantification is for that particular context. The domain can shift in the course of a sentence. |
18420 | We deny that action involves some special class of beliefs [Cappelen/Dever] |
Full Idea: Maybe there is a class of beliefs that plays a special role in the explanation of action. We have argued against the existence of such a class (or at least any interesting such class). | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 06.2) | |
A reaction: The main class which has been proposed is the one that involves indexical beliefs. I agree with this idea. |
22331 | Moral statements are imperatives rather than the avowals of emotion - but universalisable [Hare, by Glock] |
Full Idea: According to Hare's universal prescriptivism, moral statements are closer to imperatives than to avowals of emotion; their purpose is to guide action. But unlike imeperatives they are universalisable. | |
From: report of Richard M. Hare (Freedom and Reason [1963]) by Hans-Johann Glock - What is Analytic Philosophy? 2.9 | |
A reaction: Why isn't 'everyone ought to support West Ham' a moral judgement? |
22484 | Universalised prescriptivism could be seen as implying utilitarianism [Hare, by Foot] |
Full Idea: Hare has suggested that a fairly tight form of utilitarianism can be obtained from universalised prescriptivism. | |
From: report of Richard M. Hare (Freedom and Reason [1963]) by Philippa Foot - Does Moral Subjectivism Rest on a Mistake? p.191 | |
A reaction: All the benefits of Bentham, Kant and Hume, in one neat package! Since I take all three of them to be wrong about ethics, that counts against this idea. |
6449 | The categorical imperative leads to utilitarianism [Hare, by Nagel] |
Full Idea: Hare has proposed that utilitarianism is the ultimate standard to which we are led by the categorical imperative. | |
From: report of Richard M. Hare (Freedom and Reason [1963], p.123-4) by Thomas Nagel - Equality and Partiality | |
A reaction: It seems to me better to say that Kant starts (unwittingly) from something like utilitarianism, that is, an assumption that human happiness and welfare have some sort of intrinsic value that cannot be demonstrated. Otherwise evil can be universalised. |
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. |
