| 23890 | For Plato true wisdom is supernatural [Plato, by Weil] |
| Full Idea: It is evident that Plato regards true wisdom as something supernatural. | |
| From: report of Plato (works [c.375 BCE]) by Simone Weil - God in Plato p.61 | |
| A reaction: Taken literally, I assume this is wrong, but we can empathise with the thought. Wisdom has the feeling of rising above the level of mere knowledge, to achieve the overview I associate with philosophy. |
| 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! |
| 3060 | Plato never mentions Democritus, and wished to burn his books [Plato, by Diog. Laertius] |
| Full Idea: Plato, who mentions nearly all the ancient philosophers, nowhere speaks of Democritus; he wished to burn all of his books, but was persuaded that it was futile. | |
| From: report of Plato (works [c.375 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 09.7.8 |
| 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. |
| 23891 | Two contradictories force us to find a relation which will correlate them [Plato, by Weil] |
| Full Idea: Where contradictions appear there is a correlation of contraries, which is relation. If a contradiction is imposed on the intelligence, it is forced to think of a relation to transform the contradiction into a correlation, which draws the soul higher. | |
| From: report of Plato (works [c.375 BCE]) by Simone Weil - God in Plato p.70 | |
| A reaction: A much better account of the dialectic than anything I have yet seen in Hegel. For the first time I see some sense in it. A contradiction is not a falsehood, and it must be addressed rather than side-stepped. A kink in the system, that needs ironing. |
| 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. |
| 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? |
| 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. |
| 14502 | Plato's idea of 'structure' tends to be mathematically expressed [Plato, by Koslicki] |
| Full Idea: 'Structure' tends to be characterized by Plato as something that is mathematically expressed. | |
| From: report of Plato (works [c.375 BCE]) by Kathrin Koslicki - The Structure of Objects V.3 iv | |
| A reaction: [Koslicki is drawing on Verity Harte here] |
| 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). |
| 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. |
| 3039 | When Diogenes said he could only see objects but not their forms, Plato said it was because he had eyes but no intellect [Plato, by Diog. Laertius] |
| Full Idea: When Diogenes told Plato he saw tables and cups, but not 'tableness' and 'cupness', Plato replied that this was because Diogenes had eyes but no intellect. | |
| From: report of Plato (works [c.375 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 06.2.6 |
| 17948 | Plato's Forms meant that the sophists only taught the appearance of wisdom and virtue [Plato, by Nehamas] |
| Full Idea: Plato's theory of Forms allowed him to claim that the sophists and other opponents were trapped in the world of appearance. What they therefore taught was only apparent wisdom and virtue. | |
| From: report of Plato (works [c.375 BCE]) by Alexander Nehamas - Eristic,Antilogic,Sophistic,Dialectic p.118 |
| 20906 | Platonists argue for the indivisible triangle-in-itself [Plato, by Aristotle] |
| Full Idea: The Platonists, on the basis of purely logical arguments, posit the existence of an indivisible 'triangle in itself'. | |
| From: report of Plato (works [c.375 BCE]) by Aristotle - Coming-to-be and Passing-away (Gen/Corr) 316a15 | |
| A reaction: A helpful confirmation that geometrical figures really are among the Forms (bearing in mind that numbers are not, because they contain one another). What shape is the Form of the triangle? |
| 556 | If there is one Form for both the Form and its participants, they must have something in common [Aristotle on Plato] |
| Full Idea: If there is the same Form for the Forms and for their participants, then they must have something in common. | |
| From: comment on Plato (works [c.375 BCE]) by Aristotle - Metaphysics 991a |
| 563 | If gods are like men, they are just eternal men; similarly, Forms must differ from particulars [Aristotle on Plato] |
| Full Idea: We say there is the form of man, horse and health, but nothing else, making the same mistake as those who say that there are gods but that they are in the form of men. They just posit eternal men, and here we are not positing forms but eternal sensibles. | |
| From: comment on Plato (works [c.375 BCE]) by Aristotle - Metaphysics 997b |
| 565 | The Forms cannot be changeless if they are in changing things [Aristotle on Plato] |
| Full Idea: The Forms could not be changeless if they were in changing things. | |
| From: comment on Plato (works [c.375 BCE]) by Aristotle - Metaphysics 998a |
| 557 | A Form is a cause of things only in the way that white mixed with white is a cause [Aristotle on Plato] |
| Full Idea: A Form is a cause of things only in the way that white mixed with white is a cause. | |
| From: comment on Plato (works [c.375 BCE]) by Aristotle - Metaphysics 991a |
| 9607 | The greatest discovery in human thought is Plato's discovery of abstract objects [Brown,JR on Plato] |
| Full Idea: The greatest discovery in the history of human thought is Plato's discovery of abstract objects. | |
| From: comment on Plato (works [c.375 BCE]) by James Robert Brown - Philosophy of Mathematics Ch. 2 | |
| A reaction: Compare Idea 2860! Given the diametrically opposed views, it is clearly likely that Plato's central view is the most important idea in the history of human thought, even if it is wrong. |
| 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? |
| 13263 | We can grasp whole things in science, because they have a mathematics and a teleology [Plato, by Koslicki] |
| Full Idea: Due to the mathematical nature of structure and the teleological cause underlying the creation of Platonic wholes, these wholes are intelligible, and are in fact the proper objects of science. | |
| From: report of Plato (works [c.375 BCE]) by Kathrin Koslicki - The Structure of Objects 5.3 | |
| A reaction: I like this idea, because it pays attention to the connection between how we conceive objects to be, and how we are able to think about objects. Only examining these two together enables us to grasp metaphysics. |
| 13261 | Plato sees an object's structure as expressible in mathematics [Plato, by Koslicki] |
| Full Idea: The 'structure' of an object tends to be characterised by Plato as something that is mathematically expressible. | |
| From: report of Plato (works [c.375 BCE]) by Kathrin Koslicki - The Structure of Objects 5.3 | |
| A reaction: This seems to be pure Pythagoreanism (see Idea 644). Plato is pursuing Pythagoras's research programme, of trying to find mathematics buried in every aspect of reality. |
| 13265 | Plato was less concerned than Aristotle with the source of unity in a complex object [Plato, by Koslicki] |
| Full Idea: Plato was less concerned than Aristotle with the project of how to account, in completely general terms, for the source of unity within a mereologically complex object. | |
| From: report of Plato (works [c.375 BCE]) by Kathrin Koslicki - The Structure of Objects 5.5 | |
| A reaction: Plato seems to have simply asserted that some sort of harmony held things together. Aristotles puts the forms [eidos] within objects, rather than external, so he has to give a fuller account of what is going on in an object. He never managed it! |
| 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? |
| 593 | Plato's holds that there are three substances: Forms, mathematical entities, and perceptible bodies [Plato, by Aristotle] |
| Full Idea: Plato's doctrine was that the Forms and mathematicals are two substances and that the third substance is that of perceptible bodies. | |
| From: report of Plato (works [c.375 BCE]) by Aristotle - Metaphysics 1028b |
| 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. |
| 13260 | Plato says wholes are either containers, or they're atomic, or they don't exist [Plato, by Koslicki] |
| Full Idea: Plato considers a 'container' model for wholes (which are disjoint from their parts) [Parm 144e3-], and a 'nihilist' model, in which only wholes are mereological atoms, and a 'bare pluralities' view, in which wholes are not really one at all. | |
| From: report of Plato (works [c.375 BCE]) by Kathrin Koslicki - The Structure of Objects 5.2 | |
| A reaction: [She cites Verity Harte for this analysis of Plato] The fourth, and best, seems to be that wholes are parts which fall under some unifying force or structure or principle. |
| 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! |
| 11237 | Only universals have essence [Plato, by Politis] |
| Full Idea: Plato argues that only universals have essence. | |
| From: report of Plato (works [c.375 BCE]) by Vassilis Politis - Aristotle and the Metaphysics 1.4 |
| 11238 | Plato and Aristotle take essence to make a thing what it is [Plato, by Politis] |
| Full Idea: Plato and Aristotle have a shared general conception of essence: the essence of a thing is what that thing is simply in virtue of itself and in virtue of being the very thing it is. It answers the question 'What is this very thing?' | |
| From: report of Plato (works [c.375 BCE]) by Vassilis Politis - Aristotle and the Metaphysics 1.4 |
| 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! |
| 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. |
| 19696 | There are reasons 'for which' a belief is held, reasons 'why' it is believed, and reasons 'to' believe it [Neta] |
| Full Idea: We must distinguish between something's being a 'reason for which' a creature believes something, and its being a 'reason why' a creature believes something. ...We must also distinguish a 'reason for which' from a 'reason to' believe something. | |
| From: Ram Neta (The Basing Relation [2011], Intro) | |
| A reaction: He doesn't spell the distinctions out clearly. I take it that 'for which' is my personal justification, 'why' is the dodgy prejudices that cause my belief. and 'to' is some actual good reasons, of which I may be unaware. |
| 19697 | The basing relation of a reason to a belief should both support and explain the belief [Neta] |
| Full Idea: A reason has a 'basing relation' with a belief if it (i) rationally supports holding the belief, and (ii) explains why the belief is held. | |
| From: Ram Neta (The Basing Relation [2011], Intro) | |
| A reaction: Presumably a false reason would fit this account. Why not talk of 'grounding', or is that word now reserved for metaphysics? If I hypnotise you into a belief, would my hypnotic power be the basing reason? Fits (ii), but not (i). |
| 17085 | A good explanation totally rules out the opposite explanation (so Forms are required) [Plato, by Ruben] |
| Full Idea: For Plato, an acceptable explanation is one such that there is no possibility of there being the opposite explanation at all, and he thought that only explanations in terms of the Forms, but never physical explanations, could meet this requirement. | |
| From: report of Plato (works [c.375 BCE]) by David-Hillel Ruben - Explaining Explanation Ch 2 | |
| A reaction: [Republic 436c is cited] |
| 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! |
| 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. |
| 1651 | Plato wanted to somehow control and purify the passions [Vlastos on Plato] |
| Full Idea: Plato put high on his agenda a project which did not figure in Socrates' programme at all: the hygienic conditioning of the passions. This cannot be an intellectual process, as argument cannot touch them. | |
| From: comment on Plato (works [c.375 BCE]) by Gregory Vlastos - Socrates: Ironist and Moral Philosopher p.88 | |
| A reaction: This is the standard traditional view of any thinker who exaggerates the importance and potential of reason in our lives. |
| 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) |
| 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. |
| 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. |
| 3324 | Plato's whole philosophy may be based on being duped by reification - a figure of speech [Benardete,JA on Plato] |
| Full Idea: Plato is liable to the charge of having been duped by a figure of speech, albeit the most profound of all, the trope of reification. | |
| From: comment on Plato (works [c.375 BCE]) by José A. Benardete - Metaphysics: the logical approach Ch.12 | |
| A reaction: That might be a plausible account if his view was ridiculous, but given how many powerful friends Plato has, especially in the philosophy of mathematics, we should assume he was cleverer than that. |
| 7503 | Plato never refers to examining the conscience [Plato, by Foucault] |
| Full Idea: Plato never speaks of the examination of conscience - never! | |
| From: report of Plato (works [c.375 BCE]) by Michel Foucault - On the Genealogy of Ethics p.276 | |
| A reaction: Plato does imply some sort of self-evident direct knowledge about that nature of a healthy soul. Presumably the full-blown concept of conscience is something given from outside, from God. In 'Euthyphro', Plato asserts the primacy of morality (Idea 337). |
| 2173 | As religion and convention collapsed, Plato sought morals not just in knowledge, but in the soul [Williams,B on Plato] |
| Full Idea: Once gods and fate and social expectation were no longer there, Plato felt it necessary to discover ethics inside human nature, not just as ethical knowledge (Socrates' view), but in the structure of the soul. | |
| From: comment on Plato (works [c.375 BCE]) by Bernard Williams - Shame and Necessity II - p.43 | |
| A reaction: anti Charles Taylor |
| 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' |
| 9274 | Plato's legacy to European thought was the Good, the Beautiful and the True [Plato, by Gray] |
| Full Idea: Plato's legacy to European thought was a trio of capital letters - the Good, the Beautiful and the True. | |
| From: report of Plato (works [c.375 BCE]) by John Gray - Straw Dogs 2.8 | |
| A reaction: It seems to have been Baumgarten who turned this into a slogan (Idea 8117). Gray says these ideals are lethal, but I identify with them very strongly, and am quite happy to see the good life as an attempt to find the right balance between them. |
| 94 | Pleasure is better with the addition of intelligence, so pleasure is not the good [Plato, by Aristotle] |
| Full Idea: Plato says the life of pleasure is more desirable with the addition of intelligence, and if the combination is better, pleasure is not the good. | |
| From: report of Plato (works [c.375 BCE]) by Aristotle - Nicomachean Ethics 1172b27 | |
| A reaction: It is obvious why we like pleasure, but not why intelligence makes it 'better'. Maybe it is just because we enjoy intelligence? |
| 17947 | Plato decided that the virtuous and happy life was the philosophical life [Plato, by Nehamas] |
| Full Idea: Plato came to the conclusion that virtue and happiness consist in the life of philosophy itself. | |
| From: report of Plato (works [c.375 BCE]) by Alexander Nehamas - Eristic,Antilogic,Sophistic,Dialectic p.117 | |
| A reaction: This view is obviously ridiculous, because it largely excludes almost the entire human race, which sees philosophy as a cul-de-sac, even if it is good. But virtue and happiness need some serious thought. |
| 6015 | Plato, unusually, said that theoretical and practical wisdom are inseparable [Plato, by Kraut] |
| Full Idea: Two virtues that are ordinarily kept distinct - theoretical and practical wisdom - are joined by Plato; he thinks that neither one can be fully possessed unless it is combined with the other. | |
| From: report of Plato (works [c.375 BCE]) by Richard Kraut - Plato | |
| A reaction: I get the impression that this doctrine comes from Socrates, whose position is widely reported as 'intellectualist'. Aristotle certainly held the opposite view. |
| 2912 | Plato is boring [Nietzsche on Plato] |
| Full Idea: Plato is boring. | |
| From: comment on Plato (works [c.375 BCE]) by Friedrich Nietzsche - Twilight of the Idols 9.2 |
| 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). |
| 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. |
| 1526 | Almost everyone except Plato thinks that time could not have been generated [Plato, by Aristotle] |
| Full Idea: With a single exception (Plato) everyone agrees about time - that it is not generated. Democritus says time is an obvious example of something not generated. | |
| From: report of Plato (works [c.375 BCE]) by Aristotle - Physics 251b14 |
| 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). |
