| 18495 | The best philosophers I know are the best people I know [Heil] |
| Full Idea: Philosophers are not invariably the best people, but the best philosophers I know are the best people I know. | |
| From: John Heil (The Universe as We Find It [2012], Pref) | |
| A reaction: How very nicely expressed. I have often thought the same about lovers of literature, but been horribly disappointed by some of them. On the whole I have found philosophy-lovers to be slightly superior to literature-lovers! |
| 3879 | Philosophy aims to provide a theory of everything [Scruton] |
| Full Idea: Philosophy studies everything: it tries to provide a theory of the whole of things. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 1.2) | |
| A reaction: Good, but you can't avoid value-judgements about which things are important; philosophers place more value on moral theories than on theories about glacier movement. There is a tension in philosophy between human and eternal concerns. |
| 18494 | Using a technical vocabulary actually prevents discussion of the presuppositions [Heil] |
| Full Idea: Sharing a technical vocabulary is to share a tidy collection of assumptions. Reliance on that vocabulary serves to foreclose discussion of those assumptions. | |
| From: John Heil (The Universe as We Find It [2012], Pref) | |
| A reaction: Love it! I am endlessly frustrated by papers that launch into a discussion using a terminology that is riddled with dubious prior assumptions. And that includes common terms like 'property', as well as obscure neologisms. |
| 18506 | Questions of explanation should not be confused with metaphyics [Heil] |
| Full Idea: There is an unfortunate tendency to conflate epistemological issues bearing on explanation with issues in metaphysics. | |
| From: John Heil (The Universe as We Find It [2012], 01.2) | |
| A reaction: This is where Heil and I part ways. I just don't believe in the utterly pure metaphysics which he thinks we can do. Our drive to explain moulds our vision of reality, say I. |
| 18535 | Without abstraction we couldn't think systematically [Heil] |
| Full Idea: A capacity for abstraction is central to our capacity to think about the universe systematically. | |
| From: John Heil (The Universe as We Find It [2012], 09.7) | |
| A reaction: This strikes me as obvious. We pick out the similarities, and then discuss them, as separate from their bearers. We explain why things have features in common. Some would just say systematic thinking needs universals, but that's less good. |
| 3891 | If p entails q, then p is sufficient for q, and q is necessary for p [Scruton] |
| Full Idea: If p entails q, then p is sufficient for q, and q is necessary for p. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 15.7) |
| 3894 | We may define 'good' correctly, but then ask whether the application of the definition is good [Scruton] |
| Full Idea: The 'open question' argument is clearly invalid. A question remains open just so long as our ignorance permits. …It may be an open question whether promoting happiness is good, even though this is what 'good' means. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 20.1) | |
| A reaction: A nice objection. Like small children, we can keep asking questions forever. Whether there is a question to be asked about a thing is not a property of that thing, but of us who ask it. |
| 3883 | A true proposition is consistent with every other true proposition [Scruton] |
| Full Idea: A true proposition is consistent with every other true proposition: no truth is contradicted by another. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 9.1) | |
| A reaction: Interesting. It resembles the rule that if you always tell the truth you don't need to remember what you said. Close to the heart of the concept of truth. Coherence and correspondence. |
| 18534 | Truth relates truthbearers to truthmakers [Heil] |
| Full Idea: Truth is a relation between a truthbearer and a truthmaker. | |
| From: John Heil (The Universe as We Find It [2012], 08.02) | |
| A reaction: This implies that all truths have truthmakers, which is fairly controversial. Heil himself denies it! |
| 18531 | Philosophers of the past took the truthmaking idea for granted [Heil] |
| Full Idea: For millenia, philosophers operated with an implicit conception of truthmaking, a conception that remained unarticulated only because it was part of the very fabric of philosophy. | |
| From: John Heil (The Universe as We Find It [2012], 07.2) | |
| A reaction: Presumably it is an advance that we have brought it out into the open, and subjected it to critical study. Does Heil want us to return to it being unquestioned? I like truthmaking, but that can't be right. |
| 18509 | Not all truths need truthmakers - mathematics and logic seem to be just true [Heil] |
| Full Idea: I do not subscribe to the thesis that every truth requires a truthmaker. Mathematical truths and truths of logic are compatible with any way the universe could be. | |
| From: John Heil (The Universe as We Find It [2012], 01.5) | |
| A reaction: He makes that sound like a knock-down argument, but I'm not convinced. I see logic and mathematics as growing out of nature, though that is a very unfashionable view. I'm almost ashamed of it. But I'm not giving it up. See Carrie Jenkins. |
| 3884 | The pragmatist does not really have a theory of truth [Scruton] |
| Full Idea: The pragmatist does not really have a theory of truth. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 9.4) |
| 3907 | Could you be intellectually acquainted with numbers, but unable to count objects? [Scruton] |
| Full Idea: Could someone have a perfect intellectual acquaintance with numbers, but be incapable of counting a flock of sheep? | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 26.6) |
| 18518 | Infinite numbers are qualitatively different - they are not just very large numbers [Heil] |
| Full Idea: It is a mistake to think of an infinite number as a very large number. Infinite numbers differ qualitatively from finite numbers. | |
| From: John Heil (The Universe as We Find It [2012], 03.5) | |
| A reaction: He cites Dedekind's idea that a proper subset of an infinite number can match one-one with the number. Respectable numbers don't behave in this disgraceful fashion. This should be on the wall of every seminar on philosophy of mathematics. |
| 18500 | How could structures be mathematical truthmakers? Maths is just true, without truthmakers [Heil] |
| Full Idea: I do not understand how structures could serve as truthmakers for mathematical truths, ...Mathematical truths are not true in virtue of any way the universe is. ...Mathematical truths hold, whatever ways the universe is. | |
| From: John Heil (The Universe as We Find It [2012], 08.08) | |
| A reaction: I like the idea of enquiring about truthmakers for mathematical truths (and my view is more empirical than Heil's), but I think it may be a misunderstanding to think that structures are intended as truthmakers. Mathematics just IS structures? |
| 3908 | If maths contains unprovable truths, then maths cannot be reduced to a set of proofs [Scruton] |
| Full Idea: If there can be unprovable truths of mathematics, then mathematics cannot be reduced to the proofs whereby we construct it. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 26.7) |
| 18539 | Our categories lack the neat arrangement needed for reduction [Heil] |
| Full Idea: Categories we use to describe and explain our universe do not line up in the neat way reductive schemes require. | |
| From: John Heil (The Universe as We Find It [2012], 13.2) | |
| A reaction: He takes reduction to be largely a relation between our categories, rather than between entities, so he is bound to get this result. He may be right. |
| 18505 | Fundamental ontology aims at the preconditions for any true theory [Heil] |
| Full Idea: Fundamental ontology is in the business of telling us what the universe must be like if any theory is true. | |
| From: John Heil (The Universe as We Find It [2012], 01.1) | |
| A reaction: Heil is good at stating simple ideas simply. This seems to be a bold claim, but I think I agree with it. |
| 18499 | Our quantifications only reveal the truths we accept; the ontology and truthmakers are another matter [Heil] |
| Full Idea: Looking at what you quantify over reveals, at most, truths to which you are committed. What the ontology is, what the truthmakers are for these truths, is another matter, one tackled, if at all, only in the pursuit of fundamental physics. | |
| From: John Heil (The Universe as We Find It [2012], 08.08) | |
| A reaction: Exactly right. Nouns don't guarantee objects, verbs don't guarantee processes. If you want to know my ontological commitments, ask me about them! Don't infer them from the sentences I hold true, because they need interpreting. |
| 18512 | Ontology aims to give the fundamental categories of being [Heil] |
| Full Idea: The task of ontology is to spell out the fundamental categories of being. | |
| From: John Heil (The Universe as We Find It [2012], 02.5) | |
| A reaction: This is the aspiration of 'pure' metaphysics, which I don't quite believe in. There is too much convention involved, on the one hand, and physics on the other. |
| 18508 | Most philosophers now (absurdly) believe that relations fully exist [Heil] |
| Full Idea: It is a measure of how far we have fallen that so few philosophers nowadays see any difficulty at all in the idea that relations have full ontological standing. | |
| From: John Heil (The Universe as We Find It [2012], 01.4) | |
| A reaction: We have 'fallen' because medieval metaphysicians didn't believe it. Russell seems to have started, and the tendency to derive ontology from logic has secured the belief in relations. How else can you be allowed to write aRb? I agree with Heil. |
| 18532 | If causal relations are power manifestations, that makes them internal relations [Heil] |
| Full Idea: If causal relations are the manifesting of powers, then causal relations would appear to be a species of internal relation. | |
| From: John Heil (The Universe as We Find It [2012], 07.4) | |
| A reaction: The point being that any relations formed are entirely dependent on the internal powers of the relata. Sounds right. There are also non-causal relations, of course. |
| 18510 | We need properties to explain how the world works [Heil] |
| Full Idea: When a tomato depresses a scale, it does so in virtue of its mass - how it is masswise - and not in virtue of its colour or shape. Were we barred from saying such things, we would be unable to formulate truths about the fundamental things. | |
| From: John Heil (The Universe as We Find It [2012], 02.3) | |
| A reaction: It doesn't follow that we have an ontological commitment to properties, but we certainly need to point out the obvious fact that things being one way rather than another makes a difference to what happens. |
| 18522 | Categorical properties were introduced by philosophers as actual properties, not if-then properties [Heil] |
| Full Idea: Categorical properties were introduced originally by philosophers bent on distinguishing properties possessed 'categorically', that is, actually, by objects from mere if-then, conditional properties, mere potentialities. | |
| From: John Heil (The Universe as We Find It [2012], 04.3) | |
| A reaction: He cites Ryle on dispositions in support. It is questionable whether it is a clear or useful distinction. Heil says the new distinction foreclosed the older more active view of properties. |
| 18513 | Emergent properties will need emergent substances to bear them [Heil] |
| Full Idea: If you are going to have emergent fundamental properties, you are going to need emergent fundamental substances as bearers of those properties. | |
| From: John Heil (The Universe as We Find It [2012], 02.6) | |
| A reaction: Presumably the theory of emergent properties (which I take to be nonsense, in its hardcore form) says that the substance is unchanged, but the property is new. Or else the bundle gives collective birth to a new member. Search me. |
| 18540 | Predicates only match properties at the level of fundamentals [Heil] |
| Full Idea: Only when you get to fundamental physics, do predicates begin to line up with properties. | |
| From: John Heil (The Universe as We Find It [2012], 13.2) | |
| A reaction: A nice thought. I assume the actual properties of daily reality only connect to our predicates in very sloppy ways. I suppose our fundamental predicates have to converge on the actual properties, because the fog clears. Sort of. |
| 18533 | In Fa, F may not be a property of a, but a determinable, satisfied by some determinate [Heil] |
| Full Idea: It may be that F applies truly to a because F is a determinable predicate satisfied by a's possession of a property answering to a determinate of that determinable predicate. | |
| From: John Heil (The Universe as We Find It [2012], 08.01) | |
| A reaction: Heil aims to break the commitment of predicates to the existence of properties. The point is that there is no property 'coloured' to correspond to 'a is coloured'. Red might be the determinate that does the job. Nice. |
| 18511 | Properties have causal roles which sets can't possibly have [Heil] |
| Full Idea: Properties are central to the universe's causal order in a way that sets could not possibly be. | |
| From: John Heil (The Universe as We Find It [2012], 02.3) | |
| A reaction: The idea that properties actually are sets is just ridiculous. It may be that you can treat them as sets and get by quite well. The sets can be subsumed into descriptions of causal processes (or something). |
| 3906 | If possible worlds are needed to define properties, maybe we should abandon properties [Scruton] |
| Full Idea: If the only way of defining properties involves quantifying over possible worlds, this could be taken as another reason for abandoning properties altogether. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 26.4) |
| 16755 | The possible Aristotelian view that forms are real and active principles is clearly wrong [Fine,K, by Pasnau] |
| Full Idea: Aristotle seems to have a possible basis for the belief [in individual forms], namely that forms are real and active principles in the world, which is denied by any right-minded modern. | |
| From: report of Kit Fine (A Puzzle Concerning Matter and Form [1994], p.19) by Robert Pasnau - Metaphysical Themes 1274-1671 24.3 n8 | |
| A reaction: Pasnau says this is the view of forms promoted by the scholastics, whereas Aristotle's own view should be understood as 'metaphysical'. |
| 18523 | Are all properties powers, or are there also qualities, or do qualities have the powers? [Heil] |
| Full Idea: Some philosophers who embrace properties as powers hold that every property is a power (Bird), or that some properties are qualities and some are powers (Ellis; Molnar). The latter include powers which are 'grounded in' qualities (Mumford). | |
| From: John Heil (The Universe as We Find It [2012], 04.4) | |
| A reaction: I don't like Heil's emphasis on 'qualities', which seems to imply their phenomenal rather than their real aspect. I'm inclined to favour the all-powers view, but can't answer the question 'but what HAS these powers?' Stuff is intrinsically powerful. |
| 18524 | Properties are both qualitative and dispositional - they are powerful qualities [Heil] |
| Full Idea: In my account of properties they are at once qualitative and dispositional: properties are powerful qualities. | |
| From: John Heil (The Universe as We Find It [2012], 05.1) | |
| A reaction: I have never managed to understand what Heil means by 'qualities'. Is he talking about the phenomenal aspects of powers? Does he mean categorical properties. I can't find an ontological space for his things to slot into. |
| 18498 | Abstract objects wouldn't be very popular without the implicit idea of truthmakers [Heil] |
| Full Idea: It would be difficult to understand the popularity of 'abstract entities' - numbers, sets, propositions - in the absence of an implicit acknowledgement of the importance of truthmakers. | |
| From: John Heil (The Universe as We Find It [2012], 08.07) | |
| A reaction: I love Idea 18496, because it leads us towards a better account of modality, but dislike this one because it reveals that the truthmaking idea has led us to a very poor theory. Truthmaking is a good question, but not much of an answer? |
| 18507 | Substances bear properties, so must be simple, and not consist of further substances [Heil] |
| Full Idea: Substances, as property bearers, must be simple; substances of necessity lack constituents that are themselves substances. | |
| From: John Heil (The Universe as We Find It [2012], 01.3) | |
| A reaction: How can he think that this is a truth of pure metaphysics? A crowd has properties because we think of it as a simple substance, not because it actually is one. Can properties have properties? Are tree and leaf both substances? |
| 18515 | Spatial parts are just regions, but objects depend on and are made up of substantial parts [Heil] |
| Full Idea: An object is not made up of its spatial parts: spatial parts are regions of some object. ...Complex objects, wholes, are made up of, and so depend on, their substantial parts. | |
| From: John Heil (The Universe as We Find It [2012], 03.1) | |
| A reaction: Presumably objects also 'depend on' their spatial parts, so I am not convinced that we have a sharp distinction here. |
| 18516 | A 'gunky' universe would literally have no parts at all [Heil] |
| Full Idea: Blancmange 'gunky' universes are not just universes with an endless number of parts. Rather a blancmange universe is a universe with no simple parts, no parts themselves lacking parts. | |
| From: John Heil (The Universe as We Find It [2012], 03.3) | |
| A reaction: Hm. Lewis seemed to think it was parts all the way down. Is gunk homogeneous stuff, or what is endlessly subdividable, or an infinite shrinking of parts? We demand clarity. |
| 18514 | Many wholes can survive replacement of their parts [Heil] |
| Full Idea: A whole - or some wholes - might be thought to survive gradual replacement of its parts, perhaps, but not their elimination. | |
| From: John Heil (The Universe as We Find It [2012], 03.1) | |
| A reaction: You can't casually replace the precious golden parts of a statue with cheap lead ones. It depends on whether the parts matter. Nevertheless this is a really important idea in metaphysics. It enables the s=Ship of Theseus to survive some change. |
| 18517 | Dunes depend on sand grains, but line segments depend on the whole line [Heil] |
| Full Idea: A sand dune depends on the individual grains of sand that make it up. In an important sense, however, a line's segments depend on the line rather than it on them. | |
| From: John Heil (The Universe as We Find It [2012], 03.4) | |
| A reaction: The illustrations are not clear cut. As you cut off segments of the line, you reduce its length. Heil is hoping for something neat here, but I don't think he has quite got. The difficulty of trying to do pure metaphysics! |
| 3888 | Hume assumes that necessity can only be de dicto, not de re [Scruton] |
| Full Idea: It was one of the assumptions of Hume's empiricism that all necessities are de dicto: i.e. they are artefacts of language. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 13.5) |
| 18502 | If basic physics has natures, then why not reality itself? That would then found the deepest necessities [Heil] |
| Full Idea: If electrons and gravitational fields have definite natures, why not reality itself? And if reality has a nature, if this makes sense, then reality grounds the deepest necessities of all. | |
| From: John Heil (The Universe as We Find It [2012], 08.09) | |
| A reaction: Nice speculation! Scientists and verificationists seem to cry 'foul!' when philosophers offer such wild speculations, but I say that's exactly what we pay them do. I'm not sure whether I understand reality having its own nature, though! |
| 3903 | The conceivable can't be a test of the possible, if there are things which are possible but inconceivable [Scruton] |
| Full Idea: If there are things which are possible but inconceivable, we must abandon the view, which has had a considerable following since Descartes, that the conceivable is a test of the possible. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 25) |
| 18496 | If possible worlds are just fictions, they can't be truthmakers for modal judgements [Heil] |
| Full Idea: If the other possible worlds are merely useful fictions, we are left wondering what the truthmakers for all those modal judgements might be. | |
| From: John Heil (The Universe as We Find It [2012], 08.07) | |
| A reaction: I suddenly see that this is the train of thought that led me to believe in real powers and dispositions, and which retrospectively led me to love the truthmaker idea. Even real Lewisian worlds don't seem adequate as truthmakers here. |
| 3897 | Epistemology is about the justification of belief, not the definition of knowledge [Scruton] |
| Full Idea: In my view the concept of knowledge is of no very great interest in epistemology, which actually concerns the justification of belief. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 22) | |
| A reaction: I think this is an excellent thought. I see knowledge as slippery, and partially contextual, and I don't care whether someone precisely 'knows' something. I just want to know why they believe it. |
| 3881 | In the Cogito argument consciousness develops into self-consciousness [Scruton] |
| Full Idea: In the course of the argument the first person has acquired a character; he is not merely conscious, but self-conscious. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 4) |
| 3887 | Maybe our knowledge of truth and causation is synthetic a priori [Scruton] |
| Full Idea: 'Every event has a cause' and 'truth is correspondence to facts' are candidates for being synthetic a priori knowledge. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 13.2) |
| 3901 | Touch only seems to reveal primary qualities [Scruton] |
| Full Idea: Touch seems to deliver a purely primary-quality account of the world. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 24) | |
| A reaction: Interesting, though a little over-confident. It seems occasionally possible for touch to be an illusion. |
| 3885 | We only conceive of primary qualities as attached to secondary qualities [Scruton] |
| Full Idea: Bradley argued that we cannot conceive of primary qualities except as attached to secondary qualities. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 10.1) |
| 3910 | If primary and secondary qualities are distinct, what has the secondary qualities? [Scruton] |
| Full Idea: If primary and secondary qualities are distinct, what do secondary qualities inhere in? | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], Ch.10 n) | |
| A reaction: What is the problem? A pin causes me pain, but I know the pain isn't in the pin. It is the same with colour. It is a mental property, if you like, triggered by a wavelength of radiation. |
| 3899 | The representational theory says perceptual states are intentional states [Scruton] |
| Full Idea: The representational theory is the unsurprising view that perceptual states are intentional, like beliefs, emotions and desires. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 23.3) |
| 3898 | My belief that it will rain tomorrow can't be caused by its raining tomorrow [Scruton] |
| Full Idea: It is impossible that my present belief that it will rain tomorrow is caused by its raining tomorrow. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 22.4) | |
| A reaction: This doesn't demolish a causal account of belief. It would be very surprising if I were to believe it was going to rain tomorrow for no cause whatsoever. That would be irrational. |
| 3880 | Logical positivism avoids scepticism, by closing the gap between evidence and conclusion [Scruton] |
| Full Idea: If the evidence for p is q, and that is the only evidence there is or can be, then 'p' means q. Hence there is no gap between evidence and conclusion, and the sceptical problem does not arise. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 3.2) |
| 3878 | Why should you believe someone who says there are no truths? [Scruton] |
| Full Idea: A writer who says that there are no truths, or that all truth is 'merely relative', is asking you not to believe him. So don't. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 1.1) |
| 18525 | Mental abstraction does not make what is abstracted mind-dependent [Heil] |
| Full Idea: Talk of abstraction and 'partial consideration' (Locke) does not make what is abstracted mind-dependent. In abstracting, you attend to what is there to be considered. | |
| From: John Heil (The Universe as We Find It [2012], 05.7) | |
| A reaction: Quite so. The point is to focus on aspects of reality. Does anyone seriously doubt that reality has 'aspects'? |
| 18504 | Only particulars exist, and generality is our mode of presentation [Heil] |
| Full Idea: Existing things are particular, and generality is a feature of our ways of representing the universe. | |
| From: John Heil (The Universe as We Find It [2012], 01.1) | |
| A reaction: This is right, and expressed with beautiful simplicity. How could anyone disagree with this? But they do! |
| 3892 | Every event having a cause, and every event being determined by its cause, are not the same [Scruton] |
| Full Idea: To say that every event has a cause is one thing; to say that every event is determined by its cause is quite another thing. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 17.1) |
| 3911 | The very concept of a substance denies the possibility of mutual interaction and dependence [Scruton] |
| Full Idea: It is often held to be a consequence of the rationalist conception of substance, that separate substances cannot interact (since causal interaction is a form of mutual dependence). | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], Ch.16 n) | |
| A reaction: Yes, substances seem incapable of interaction, just as Leibniz argues that perfections could never interact. They are too pure. |
| 18503 | You can think of tomatoes without grasping what they are [Heil] |
| Full Idea: You can entertain thoughts of things like tomatoes without a grasp of what they are. | |
| From: John Heil (The Universe as We Find It [2012], 08.10) | |
| A reaction: Lowe seemed to think that you had to grasp the generic essence of a tomato before you could think about it, but I agree entirely with Heil. |
| 18537 | Linguistic thought is just as imagistic as non-linguistic thought [Heil] |
| Full Idea: Thinking - ordinary conscious thinking - is imagistic. This is so for 'linguistic' or 'sentential' thoughts as well as for patently non-linguistic thoughts. | |
| From: John Heil (The Universe as We Find It [2012], 12.10) | |
| A reaction: This claim (that linguistic thought is just as imagistic as non-linguistic thought) strikes me as an excellent insight. |
| 18538 | Non-conscious thought may be unlike conscious thought [Heil] |
| Full Idea: Non-conscious thought need not resemble conscious thought occurring out of sight. | |
| From: John Heil (The Universe as We Find It [2012], 12.10) |
| 18536 | The subject-predicate form reflects reality [Heil] |
| Full Idea: I like to think that the subject-predicate form reflects a fundamental division in reality. | |
| From: John Heil (The Universe as We Find It [2012], 10.1) | |
| A reaction: That is, he defends the idea that there are substances, and powerful qualities pertaining to those substances. I sympathise, but this slogan makes it too simple. |
| 3882 | Wittgenstein makes it impossible to build foundations from something that is totally private [Scruton] |
| Full Idea: Wittgenstein's point is that if I search for foundations in what can only be known to me, then the belief that I have discovered those foundations will also fall victim to Descartes' demon. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 5.3) | |
| A reaction: Why should foundations based in wider society or a language community fare any better? Getting a lot of people to agree won't trouble the demon too much. Flat earthers. |
| 18497 | Many reject 'moral realism' because they can't see any truthmakers for normative judgements [Heil] |
| Full Idea: It is the difficulty in imagining what truthmakers for normative judgements might be that leads many philosophers to find 'moral realism' unappealing. | |
| From: John Heil (The Universe as We Find It [2012], 08.07) | |
| A reaction: I like that a lot. My proposal for metaethics is that it should be built on the concept of a 'value-maker' |
| 3896 | Any social theory of morality has the problem of the 'free rider', who only pretends to join in [Scruton] |
| Full Idea: Any attempt to provide a social justification of morality runs the risk of the 'free rider' - one who pretends to play the game in order to enjoy the fruits of it. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 20.6) |
| 3886 | Membership is the greatest source of obligation [Scruton] |
| Full Idea: Membership is the greatest source of obligation. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 11.2) | |
| A reaction: An interesting and rather Aristotelian idea. The alternative is individual debt or obligation. |
| 3895 | The categorical imperative is not just individual, but can be used for negotiations between strangers [Scruton] |
| Full Idea: The categorical imperative is also an instrument of negotiation and compromise between strangers, through which they can rise out of enmity and confront each other as equals. | |

| 18519 | If there were infinite electrons, they could vanish without affecting total mass-energy [Heil] |
| Full Idea: In a universe containing an infinite number of electrons would mass-energy be conserved? ...Electrons could come and go without affecting the total mass-energy. | |
| From: John Heil (The Universe as We Find It [2012], 03.6) | |
| A reaction: This seems to be a very persuasive reason for doubting that the universe contains an infinite number of electrons. In fact I suspect that infinite numbers have no bearing on nature at all. (Actually, I suspect them of being fictions). |
| 3890 | 'Cause' used to just mean any valid explanation [Scruton] |
| Full Idea: Traditionally (before Leibniz and Spinoza) the world 'cause' signified any valid explanation. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 14) |
| 18526 | We should focus on actual causings, rather than on laws and causal sequences [Heil] |
| Full Idea: I believe our understanding of causation would benefit from a shift of attention from causal sequences and laws, to instances of causation: 'causings'. | |
| From: John Heil (The Universe as We Find It [2012], 06.1) | |
| A reaction: His aim is to get away from generalities, and focus on the actual operation of powers which is involved. He likes the case of two playing cards propped against one another. I'm on his side. Laws come last in the story, and should not come first. |
| 18527 | Probabilistic causation is not a weak type of cause; it is just a probability of there being a cause [Heil] |
| Full Idea: The label 'probabilistic causation' is misleading. What you have is not a weakened or tentative kind of causing, but a probability of there being a cause. | |
| From: John Heil (The Universe as We Find It [2012], 06.5) | |
| A reaction: The idea of 'probabilistic causation' strikes me as an empty philosophers' concoction, so I agree with Heil. |
| 18520 | Electrons are treated as particles, but they lose their individuality in relations [Heil] |
| Full Idea: Although it is convenient to speak of electrons as particles or elementary substances, when they enter into relations they can 'lose their individuality. Then an electron becomes a kind of 'abstract particular', a way a given system is, a mode. | |
| From: John Heil (The Universe as We Find It [2012], 03.7) | |
| A reaction: Heil rightly warns us against basing our metaphysics on disputed theories of quantum mechanics. |
| 3904 | Measuring space requires no movement while I do it [Scruton] |
| Full Idea: I can measure the length of something only if I know that it has not moved between the moment when I locate one end of it and the moment when I locate the other. | |
| From: Roger Scruton (Modern Philosophy:introduction and survey [1994], 25.3) | |
| A reaction: A nice example of how even simple propositions have many presuppositions. |
| 18501 | Maybe the universe is fine-tuned because it had to be, despite plans by God or Nature? [Heil] |
| Full Idea: Maybe the universe is fine-tuned as it is, not because things happened to fall out as they did during and immediately after the Big Bang, or because God so ordained it, but because God or the Big Bang had no choice. | |
| From: John Heil (The Universe as We Find It [2012], 08.09) | |
| A reaction: You'd be hard put to so why it had to be fine-tuned, so this seems to be a nice speculation. Unverifiable but wholly meaningful. Maybe the stuff fine-tunes itself, by mutual interaction. Or it is the result of natural selection (Lee Smolin). |
| 3905 | 'Existence' is not a predicate of 'man', but of the concept of man, saying it has at least one instance [Scruton] |
| Full Idea: When I say that a man exists, Frege argues, I do not predicate existence of a man, but rather of the concept man: I say the concept has at least one instance (and existence is a predicate of predicates). | |
