| 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. |
| 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 |
| 4588 | There is no such thing as 'science'; there are just many different sciences [Heil] |
| Full Idea: There is no such thing as science; there are only sciences: physics, chemistry, meteorology, geology, biology, psychology, sociology. | |
| From: John Heil (Philosophy of Mind [1998], Intro) | |
| A reaction: A simple but nice point. It suggests that maybe each science has an entirely different method, and style of reasoning, experiment and explanation. Some have strict laws, others have 'ceteris paribus' laws. |
| 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. |
| 18491 | The idea of 'making' can be mere conceptual explanation (like 'because') [Künne] |
| Full Idea: If we say 'being a child of our parent's sibling makes him your first cousin', that can be paraphrased using 'because', and this is the 'because' of conceptual explanation: the second part elucidates the sense of the first part. | |
| From: Wolfgang Künne (Conceptions of Truth [2003], 3.5.2) | |
| A reaction: Fans of truth-making are certainly made uncomfortable by talk of 'what makes this a good painting' or 'this made my day'. They need a bit more sharpness to the concept of 'making' a truth. |
| 4616 | A higher level is 'supervenient' if it is determined by lower levels, but has its own natural laws [Heil] |
| Full Idea: 'Supervenience' means lower-level objects and properties suffice for the higher level ones, but the higher level is distinct from its ground, which is reflected in the higher level being governed by distinct laws of nature. | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: A nice summary of Davidson's idea. It feels wrong to me. Can I create some 'new laws of nature' by combining things novelly in a laboratory so that a supervenient state emerges. Sounds silly to me. Must we invoke God to achieve this? |
| 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] |
| 4603 | Functionalists in Fodor's camp usually say that a genuine property is one that figures in some causal laws [Heil] |
| Full Idea: Functionalists in Fodor's camp usually say that a genuine property is one that figures in some causal laws. | |
| From: John Heil (Philosophy of Mind [1998], Ch.4) | |
| A reaction: The problem is that anything which can't figure in a causal law will therefore be undetectable, so we could only speculate about the existence of such properties, never know them. |
| 4617 | A stone does not possess the property of being a stone; its other properties make it a stone [Heil] |
| Full Idea: A predicate that does not designate a property could nevertheless hold true of an object in virtue of that object's properties. An object is a stone not in virtue of holding the property of being a stone, but because it possesses certain other properties. | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: Sounds simple but important, especially in relation to the mind. We are left with the problem of how to individuate a property, and the possibility of 'basic' properties. |
| 4615 | Complex properties are not new properties, they are merely new combinations of properties [Heil] |
| Full Idea: New combinations of properties are just that: new combinations, not new properties. (This is not to reject complex properties, but only to reaffirm that complex properties are nothing over and above their constituents suitably arranged). | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: I wish I could be so confidence, but no one seems quite sure what a property is. Are they defined causally, or as 'qualities'? If the latter, what is a quality? Are there basic properties? Can properties merge to form a new one? |
| 4612 | Complex properties are just arrangements of simple properties; they do not "emerge" as separate [Heil] |
| Full Idea: Complex properties do not "emerge"; they are nothing "over and above" the properties of the simple constituents duly arranged. | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: I am glad to see someone challenging the concept of 'emergence', which strikes me as incoherent. Small properties add up to macro-properties (like 'steep', or 'square'). |
| 4587 | From the property predicates P and Q, we can get 'P or Q', but it doesn't have to designate another property [Heil] |
| Full Idea: If P and Q are predicates denoting properties, we can construct a disjunctive predicate ('P or Q'). But it is not clear that this gives us any right whatever to suppose that 'P or Q' designates a property. | |
| From: John Heil (Philosophy of Mind [1998], Pref) | |
| A reaction: An important idea, needed to disentangle our ontology from our language, and realise that they are separate. Properties are natural; predicates are conventional. |
| 4611 | The supporters of 'tropes' treat objects as bundles of tropes, when I think objects 'possess' properties [Heil] |
| Full Idea: I resist the term 'trope' as it has become common for the proponents of tropes to regard objects as "bundles" of tropes. This turns tropes into something too much resembling parts of objects for my taste. .I think an object is a possessor of properties. | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: This seems to imply a belief in 'substance', which is an intrinsically dodgy concept, but something has to exist. Keep ontology and epistemology separate! We can only know bundles of properties. |
| 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 |
| 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? |
| 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 |
| 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. |
| 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! |
| 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 |
| 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. |
| 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 |
| 4592 | If you can have the boat without its current planks, and the planks with no boat, the planks aren't the boat [Heil] |
| Full Idea: If a boat can continue to exist after the planks that currently make it up have ceased to exist, and if the planks could continue to exist when the boat does not, then a boat cannot be identified with the planks that make it up at a given time. | |
| From: John Heil (Philosophy of Mind [1998], Ch.2) | |
| A reaction: This seems obvious, but it opposes Locke's claim that the particles of an object are its identity. Does this mean identities are entirely in our heads, and not a feature of nature? I want to resist that. |
| 4586 | You can't embrace the formal apparatus of possible worlds, but reject the ontology [Heil] |
| Full Idea: We should be suspicious of anyone who embraces the formal apparatus of possible worlds while rejecting the ontology. | |
| From: John Heil (Philosophy of Mind [1998], Pref) | |
| A reaction: What matters is that good philosophy should not duck the ontological implications of any apparatus. If only embracing the 'ontology of possible worlds' were a simple matter. What makes one world 'close' to another? |
| 4591 | Idealism explains appearances by identifying appearances with reality [Heil] |
| Full Idea: Idealism explains appearances by identifying appearances with reality. | |
| From: John Heil (Philosophy of Mind [1998], Ch.2) | |
| A reaction: Nicely put. There is a certain intellectual integrity about idealism, but it is still mad. The overall picture seems to me incoherent if we don't assume that appearances are bringing us close to reality (without ever quite getting there). |
| 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] |
| 4610 | Different generations focus on either the quality of mind, or its scientific standing, or the content of thought [Heil] |
| Full Idea: One generation addresses the qualitative aspect of mentality, the next focuses on its scientific standing, its successor takes up the problem of mental content, then the cycle starts all over again… | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: This pinpoints the three interlinked questions. We seem to be currently obsessed with the quality of experience (the 'Hard Question'), but the biggest questions is how the three aspects fit together. If there are three necessities here, they must coexist. |
| 4618 | If minds are realised materially, it looks as if the material laws will pre-empt any causal role for mind [Heil] |
| Full Idea: If a mental property is realised by a material property, then it looks as though its material realiser pre-empts any causal contribution on the part of the realised mental property. | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: This has a beautiful simplicity about it. I can see how some very odd phenomena might suddenly appear out of a physical combination, but not how entirely new causal laws can be created. |
| 4621 | Whatever exists has qualities, so it is no surprise that states of minds have qualities [Heil] |
| Full Idea: Whatever exists has qualities, so it is no surprise that states of minds have qualities. | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: If only I knew what a 'quality' was. Do combinations have qualities in addition to the qualities of the components? A pair of trees, a pile of sand, a mass of neurons. |
| 4623 | Propositional attitudes are not the only intentional states; there is also mental imagery [Heil] |
| Full Idea: Some philosophers have thought that intentional states are exhausted by propositional attitudes, but what about mental imagery? You may have propositional attitudes to food, but I would wager that most of your thoughts about it are imagistic. | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: Seems right. If I encounter an object by which I am bewildered, I may form no propositions at all about it, but I can still contemplate the object. |
| 4626 | The widespread externalist view says intentionality has content because of causal links of agent to world [Heil] |
| Full Idea: The prevailing 'externalist' line on intentionality regards intentional states of mind as owing their content (what they are of, or about) to causal relations agents bear to the world. | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: This goes back to Putnam's Twin Earth. 'Meanings aren't in the head'. I may defer to experts about what 'elm' means, but I may also be arrogantly wrong about what 'juniper' means. |
| 4622 | Error must be possible in introspection, because error is possible in all judgements [Heil] |
| Full Idea: Error, like truth, presupposes judgement. Judgements you make about your conscious states are distinct from those states. This leaves room for error. | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: This sounds very neat. The reply would have to be that a lot of introspection is not judgement, but direct perception of self-evident facts and truths. I agree with Heil. |
| 4590 | If causation is just regularities in events, the interaction of mind and body is not a special problem [Heil] |
| Full Idea: If causal relations boil down to nothing more than regularities (as Hume suggests), then it is a mistake to regard the absence of a mechanism or causal link between mental events and material events as a special problem. | |
| From: John Heil (Philosophy of Mind [1998], Ch.2) | |
| A reaction: So critics of Descartes who were baffled by interaction, were actually sniffing Hume's wholesale scepticism about necessary causation. Even so, physical conjunction is more tangible than spiritual conjunction. |
| 4614 | Disposition is a fundamental feature of reality, since basic particles are capable of endless possible interactions [Heil] |
| Full Idea: If there are elementary particles, then they are certainly capable of endless interactions beyond those in which they actually engage. Everything points to dispositionality being a fundamental feature of our world. | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: I'm not convinced that my ontology has to include something called a 'disposition'. Dispositions are the consequence of how things are. Are there passive dispositions? |
| 4595 | No mental state entails inevitable behaviour, because other beliefs or desires may intervene [Heil] |
| Full Idea: Any attempt to say what behaviour follows from a given state of mind can be shown to be false by producing an example in which the state of mind is present but, owing to the addition of new beliefs and desires, the behaviour does not follow. | |
| From: John Heil (Philosophy of Mind [1998], Ch.3) | |
| A reaction: The objection seems misplaced against eliminative behaviourism, because there are held to be no mental states to correlate with the behavior. There is just behaviour, some times the same, sometimes different. |
| 4599 | Hearts are material, but functionalism says the property of being a heart is not a material property [Heil] |
| Full Idea: Although your heart is a material object, the property of being a heart is, if we accept the functionalist picture, not a material property. | |
| From: John Heil (Philosophy of Mind [1998], Ch.4) | |
| A reaction: Presumably functional properties are not physical because they are multiply realisable. The property of being a heart is more like a theoretical flow diagram than it is like a muscle. That word 'property' again… |
| 4624 | If you are a functionalist, there appears to be no room for qualia [Heil] |
| Full Idea: If you are a functionalist, there appears to be no room for qualia. | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: The problem is not that qualia must be denied, but that there is strong pressure to class them as epiphenomena. However, a raw colour can have a causal role (e.g. in an art gallery). Best to say (with Chalmers?) that functions cause qualia? |
| 4601 | Higher-level sciences cannot be reduced, because their concepts mark boundaries invisible at lower levels [Heil] |
| Full Idea: The categories definitive of a given science mark off boundaries that are largely invisible within science at lower levels. That is why there is, in general, no prospect of reducing a higher-level science to a science at some lower level. | |
| From: John Heil (Philosophy of Mind [1998], Ch.4) | |
| A reaction: This sounds slick, but I am unconvinced. Molecules only exist at the level of chemistry, but they are built up out of physics, and the 'boundaries' could be explained in physics, if you had the knowledge and patience. |
| 4602 | Higher-level sciences designate real properties of objects, which are not reducible to lower levels [Heil] |
| Full Idea: The categories embedded in a higher-level science (psychology, for instance) designate genuine properties of objects, which are not reducible to properties found in sciences at lower levels. | |
| From: John Heil (Philosophy of Mind [1998], Ch.4) | |
| A reaction: This isn't an argument against reductionism. It is obviously true that someone with a physics degree won't make a good doctor. It's these wretched 'property' things again. Is 'found repulsive by me' a property terrorists? |
| 4593 | 'Property dualism' says mind and body are not substances, but distinct families of properties [Heil] |
| Full Idea: 'Property dualism' is the view according to which the mental and the physical are not distinguishable kinds of substance, but distinct families of properties. | |
| From: John Heil (Philosophy of Mind [1998], Ch.2 n) | |
| A reaction: I am struggling to make sense of properties being in distinct families. If it is like smells and colours, it doesn't say much, and if the difference is more profound then it begins to look like old-fashioned dualism in disguise. |
| 4597 | Early identity theory talked of mind and brain 'processes', but now the focus is properties [Heil] |
| Full Idea: The early identity theorists talked of identifying mental processes with brain processes, but I am now proposing it as a theory about properties. | |
| From: John Heil (Philosophy of Mind [1998], Ch.3) | |
| A reaction: Since a process is presumably composed of more basic ontological ingredients, this is presumably a good move, but there is still a vagueness about the whole concept of a 'property'. |
| 4609 | It seems contradictory to be asked to believe that we can be eliminativist about beliefs [Heil] |
| Full Idea: Some have argued that eliminativism about propositional attitudes is self-refuting. If no one believes anything, then how could we believe the eliminativist thesis? | |
| From: John Heil (Philosophy of Mind [1998], Ch.5) | |
| A reaction: Sounds slick, but it doesn't strike me as a big problem. Presumably you don't 'believe' eliminativism. You treat some of your brain processes as if they fell into the fictional category of 'belief'. |
| 4596 | The appeal of the identity theory is its simplicity, and its solution to the mental causation problem [Heil] |
| Full Idea: The identity theory is preferable to dualism since 1) if mental events are neurological, it is easy to explain causal relations between them, and 2) if we can account for mental phenomena by reference to brains and their properties, we don't need minds. | |
| From: John Heil (Philosophy of Mind [1998], Ch.3) | |
| A reaction: One might add that it fits into the overall scientific world, and permits the possible closure of physics. The challenge is that identity theory must 'save the phenomena'. |
| 4598 | Functionalists emphasise that mental processes are not to be reduced to what realises them [Heil] |
| Full Idea: The functionalists' point is that higher-level properties like being in pain or computing the sum of 7 and 5 are not to be identified with ("reduced to") or mistaken for their realisers. | |
| From: John Heil (Philosophy of Mind [1998], Ch.4) | |
| A reaction: I take it that functionalist minds can't be reduced because they are abstractions rather than physical entities. Nevertheless, the implied ontology seems to be entirely physical, and hence in some sense reductionist. |
| 4619 | 'Multiple realisability' needs to clearly distinguish low-level realisers from what is realised [Heil] |
| Full Idea: Proponents of multiple realisability regard it as vital to distinguish realised, higher-level properties from their lower-level realisers. | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: So that the very idea of 'multiple realisability' begs the question. Minds are private, so it is never clear what has been realised, especially in non-linguistic brains. |
| 4620 | Multiple realisability is not a relation among properties, but an application of predicates to resembling things [Heil] |
| Full Idea: Multiple realisability is not a relation among properties; it is the phenomenon of predicates applying to objects in virtue of distinct, though pertinently similar, properties possessed by those objects. | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: The analogies for multiple realisability usually involve functions rather than properties or predicates (different types of corkscrew). Pain or belief in danger are not just 'predicates'. |
| 4594 | A scientist could know everything about the physiology of headaches, but never have had one [Heil] |
| Full Idea: Imagine a neuroscientist who is intimately familiar with the physiology of headaches, but who has never actually experienced a headache. | |
| From: John Heil (Philosophy of Mind [1998], Ch.3) | |
| A reaction: A more realistic version of Frank Jackson's 'Mary'. Doctors need to know that headaches are unpleasant; what they actually feel like seems irrelevant (epiphenomenal). What's it like to only have two pairs of shoes? |
| 4625 | Is mental imagery pictorial, or is it propositional? [Heil] |
| Full Idea: A fierce debate has raged between proponents of 'pictorial' conceptions of imagery (Kosslyn) and those who take imagery to be propositional (Pylyshyn). | |
| From: John Heil (Philosophy of Mind [1998], Ch.6) | |
| A reaction: This may not be a simple dilemma. Pure pictorial imagery seem possible (abstract patterns) and pure propositions are okay (maths), but in most thought they are inextricable. The image is the proposition (a nuclear cloud). |
| 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. |
| 4607 | Folk psychology and neuroscience are no more competitors than cartography and geology are [Heil] |
| Full Idea: Folk psychology and neuroscience are not competitors, any more than cartography and geology are competitors. | |
| From: John Heil (Philosophy of Mind [1998], Ch.5) | |
| A reaction: This seems true enough, unless someone like Fodor claims that the correct way to do neuroscience is to try to explicate folk psychology categories in terms of brain function. Folk psychology is fine for folk. |
| 4605 | Truth-conditions correspond to the idea of 'literal meaning' [Heil] |
| Full Idea: I intend the notion of truth-conditions to correspond to what I have called 'literal meaning'. | |
| From: John Heil (Philosophy of Mind [1998], Ch.5) | |
| A reaction: Yes. If I identify myself to you by saying "the spam is in the fridge", that always has a literal meaning (which we assemble from the words), as well as connotation in this particular context. |
| 4606 | To understand 'birds warble' and 'tigers growl', you must also understand 'tigers warble' [Heil] |
| Full Idea: There is something puzzling about the notion that someone could understand the sentences "birds warble" and "tigers growl", yet have no idea what the sentence "tigers warble" meant. | |
| From: John Heil (Philosophy of Mind [1998], Ch.5) | |
| A reaction: True enough, but this need not imply the full thesis of linguistic holism. Words are assembled like bricks. I know tigers might warble, but stones don't. Might fish warble? Or volcanoes? I must know that 'birds warble' is not a tautology. |
| 4604 | If propositions are abstract entities, how do human beings interact with them? [Heil] |
| Full Idea: Anyone who takes propositions to be abstract entities owes the rest of us an account of how human beings could interact with such things. | |
| From: John Heil (Philosophy of Mind [1998], Ch.5) | |
| A reaction: He makes this sound impossible, but that would mean that all abstraction is impossible, and there are no such things as ideas and concepts. In the end something has to be miraculous, so let it be our ability to think about abstractions. |
| 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 |
| 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 |
| 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. | |
