7278 | Words of wisdom are precise and clear [Zhuangzi (Chuang Tzu)] |
Full Idea: Words of wisdom are precise and clear. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: I can only approve of this. The issue of clarity is much discussed amongs philosophers, especially in the analytic v continental debate. Note, therefore, the additional requirement to be 'precise'. Should we be less clear in order to be precise? |
7281 | Don't even start, let's just stay put [Zhuangzi (Chuang Tzu)] |
Full Idea: Don't even start, let's just stay put. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: What a remarkable proposal! He seems frightened to make an omelette, because he will have to break an egg, or he might burn himself. I can't relate to this idea, but it's existence must be noted, like other scepticisms. |
7282 | Disagreement means you do not understand at all [Zhuangzi (Chuang Tzu)] |
Full Idea: The sage encompasses everything, while ordinary people just argue about things. Disagreement means you do not understand at all. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: This is why democracy and western analytical philosophy come as a package. We can't assume that our government is always right, and we can't assume that a 'sage' has managed to encompass everything. Criticism is essential! |
7284 | If you beat me in argument, does that mean you are right? [Zhuangzi (Chuang Tzu)] |
Full Idea: If you get the better of me in a disagreement, rather than me getting the better of you, does this mean that you are automatically right and I am automatically wrong? | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: Very nice. I don't, though, think that this invalidates the process of argument. What matters about such an exchange is the resulting reflection by the two parties. Only a fool thinks that he is right because he won, or wrong because he lost. |
5515 | Imaginary cases are good for revealing our beliefs, rather than the truth [Parfit] |
Full Idea: I believe it is worth considering imaginary cases (such as Teletransportation), as we can use them to discover, not what the truth is, but what we believe. | |
From: Derek Parfit (The Unimportance of Identity [1995], p.293) | |
A reaction: The trouble is that we might say that IF I were suddenly turned into a pig, then I would come to believe in dualism, but that will not and cannot happen, because dualism is false. It seems essential to accept the natural possibility of the case. |
458 | Nothing could come out of nothing, and existence could never completely cease [Empedocles] |
Full Idea: From what in no wise exists, it is impossible for anything to come into being; for Being to perish completely is incapable of fulfilment and unthinkable. | |
From: Empedocles (fragments/reports [c.453 BCE], B012), quoted by Anon (Lyc) - On Melissus 975b1-4 |
5112 | Empedocles says things are at rest, unless love unites them, or hatred splits them [Empedocles, by Aristotle] |
Full Idea: Empedocles claims that things are alternately changing and at rest - that they are changing whenever love is creating a unity out of plurality, or hatred is creating plurality out of unity, and they are at rest in the times in between. | |
From: report of Empedocles (fragments/reports [c.453 BCE]) by Aristotle - Physics 250b26 | |
A reaction: I suppose one must say that this an example of Ruskin's 'pathetic fallacy' - reading human emotions into the cosmos. Being constructive little creatures, we think goodness leads to construction. I'm afraid Empedocles is just wrong. |
5516 | Reduction can be by identity, or constitution, or elimination [Parfit, by PG] |
Full Idea: We can distinguish Identifying Reductionism (as in 'persons are bodies'), or Constitutive Reductionism (as in 'persons are distinct, but consist of thoughts etc.'), or Eliminative Reductionism (as in 'there are no persons, only thoughts etc.'). | |
From: report of Derek Parfit (The Unimportance of Identity [1995], p.295) by PG - Db (ideas) | |
A reaction: Constitutive Reductionism seems the most common one, as in 'chemistry just consists of lots of complicated physics'. He doesn't mention bridge laws, which are presumably only required in more complicated cases of constitutive reduction. |
13209 | There is no coming-to-be of anything, but only mixing and separating [Empedocles, by Aristotle] |
Full Idea: Empedocles says there is no coming-to-be of anything, but only a mingling and a divorce of what has been mingled. | |
From: report of Empedocles (fragments/reports [c.453 BCE]) by Aristotle - Coming-to-be and Passing-away (Gen/Corr) 314b08 | |
A reaction: Aristotle comments that this prevents Empedocleans from distinguishing between superficial alteration and fundamental change of identity. Presumably, though, that wouldn't bother them. |
457 | Substance is not created or destroyed in mortals, but there is only mixing and exchange [Empedocles] |
Full Idea: There is no creation of substance in any one of mortal existence, nor any end in execrable death, but only mixing and exchange of what has been mixed. | |
From: Empedocles (fragments/reports [c.453 BCE], B008), quoted by Plutarch - 74: Reply to Colotes 1111f | |
A reaction: also Aristotle 314b08 |
7289 | Do not try to do things, or to master knowledge; just be empty [Zhuangzi (Chuang Tzu)] |
Full Idea: Do not try to do things. Do not try to master knowledge. ...Just be empty. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.7) | |
A reaction: Stands as a nice challenge to the assumption that knowledge is a good thing. Aristotle's views make a nice contrast (Ideas 548 and 549). Personally I totally agree with Aristotle, and with the western tradition. |
23403 | You know you were dreaming when you wake, but there might then be a greater awakening from that [Zhuangzi (Chuang Tzu)] |
Full Idea: Often after waking do you know that your dream was a dream. Still, there may be an even greater awakening after which you will know that this, too, was just a greater dream. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], 02), quoted by Bryan van Norden - Intro to Classical Chinese Philosophy 9.2 | |
A reaction: This is the key to the full horror of dream scepticism (as dramatised in the film 'The Matrix'). We can never know whether there is yet another awakening about to occur. |
7285 | Did Chuang Tzu dream he was a butterfly, or a butterfly dream he was Chuang Tzu? [Zhuangzi (Chuang Tzu)] |
Full Idea: Once I, Chuang Tzu, dreamt that I was a butterfly, flitting around and enjoying myself. Suddenly I woke and was Chuang Tzu again. But had I been Chuang Tzu dreaming I was a butterfly, or a butterfly dreaming I was now Chuang Tzu? | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: Plato (Idea 2047) also spotted this problem, later made famous by Descartes (Idea 2250). Given the size of a butterfly's brain, this suggests that Chuang Tzu was a dualist. What can't I take the idea seriously, when reason says I should? |
462 | One vision is produced by both eyes [Empedocles] |
Full Idea: One vision is produced by both eyes | |
From: Empedocles (fragments/reports [c.453 BCE], B088), quoted by Strabo - works 8.364.3 |
3539 | Personal identity is just causally related mental states [Parfit, by Maslin] |
Full Idea: For Parfit all personal identity really amounts to is a chain of experiences and other psychological features causally related to each other in 'direct' sorts of ways. | |
From: report of Derek Parfit (Personal Identity [1971]) by Keith T. Maslin - Introduction to the Philosophy of Mind 10.5 | |
A reaction: When summarised like this, it strikes me that Parfit is just false to our experience, whatever Hume may say. I suspect that Parfit (and those like him) concentrate too much on rather passive perceptual experience, and neglect the will. |
5514 | Psychologists are interested in identity as a type of person, but philosophers study numerical identity [Parfit] |
Full Idea: When psychologists discuss identity, they are typically concerned with the kind of person someone is, or wants to be (as in an 'identity crisis'). But when philosophers discuss identity, it is numerical identity they mean. | |
From: Derek Parfit (The Unimportance of Identity [1995], p.293) | |
A reaction: I think it is important to note that the philosophical problem breaks down into two areas: whether I have numerical identity with myself over time, and whether other people have it. It may be that two different sets of criteria will emerge. |
1393 | One of my future selves will not necessarily be me [Parfit] |
Full Idea: If I say 'It will not be me, but one of my future selves', I do not imply that I will be that future self. He is one of my later selves, and I am one of his earlier selves. There is no underlying person we both are. | |
From: Derek Parfit (Personal Identity [1971], §5) | |
A reaction: The problem here seems to be explaining why I should care about my later self, if it isn't me. If the answer is only that it will be psychologically very similar to me, then I would care more about my current identical twin than about my future self. |
5521 | If my brain-halves are transplanted into two bodies, I have continuity, and don't need identity [Parfit] |
Full Idea: If the two halves of my brain are transplanted into different bodies just like mine, they cannot both be me, since that would make them the same person. ..But my relation to these two contains everything that matters, so identity is not what matters. | |
From: Derek Parfit (The Unimportance of Identity [1995], p.314) | |
A reaction: I challenge his concept of what 'matters'. He has a rather solipsistic view of the problem, and I take Parfit to be a rather unsociable person, since his friends and partner will be keenly interested in the identities of the new beings. |
5522 | Over a period of time what matters is not that 'I' persist, but that I have psychological continuity [Parfit] |
Full Idea: We should revise our view about identity over time: what matters isn't that there will be someone alive who will be me; it is rather that there should be at least one living person who will be psychologically continuous with me as I am now. | |
From: Derek Parfit (The Unimportance of Identity [1995], p.316) | |
A reaction: Parfit and Locke seem to agree on this, and it is no accident that they both like 'science fiction' examples. Apparently Parfit wouldn't bat an eyelid if someone threatened to cut his corpus callosum. I rate it as a catastrophe for my current existence. |
1392 | If we split like amoeba, we would be two people, neither of them being us [Parfit] |
Full Idea: In the case of the man who, like an amoeba, divides….we can suggest that he survives as two different people without implying that he is those people. | |
From: Derek Parfit (Personal Identity [1971], §1) | |
A reaction: Maybe an amoeba is a homogeneous substance for which splitting is insignificant, but when a person has certain parts that are totally crucial, splitting them is catastrophic, and quite different. I'm not sure that splitting a self would leave persons. |
5519 | It is fine to save two dying twins by merging parts of their bodies into one, and identity is irrelevant [Parfit] |
Full Idea: If I am largely paralysed, and my twin brother is dying of brain disease, then if the operation to graft my head onto his body is offered, I should accept the operation, and it is irrelevant whether this person would be me. | |
From: Derek Parfit (The Unimportance of Identity [1995], p.308) | |
A reaction: Parfit notes that the brain is a particularly significant part of the process. The fact that I might cheerfully accept this offer without philosophical worries doesn't get rid of the question 'who is this person?' Who should they remain married to? |
5520 | If two humans are merged surgically, the new identity is a purely verbal problem [Parfit] |
Full Idea: If there is someone with my head and my brother's body, it is a merely verbal question whether that person will be me, and that is why, even if it won't be me, that doesn't matter. ..What matters is not identity, but the facts of which identity consists. | |
From: Derek Parfit (The Unimportance of Identity [1995], p.310) | |
A reaction: It strikes me that from the subjective psychological point of view identity is of little interest, but from the objective external viewpoint (e.g. the forensic one) such questions are highly significant, and rightly so. |
1391 | Concern for our own lives isn't the source of belief in identity, it is the result of it [Parfit] |
Full Idea: Egoism, and the fear not of near but of distant death, and the regret that so much of one's life should have gone by - these are not, I think, wholly natural or instinctive. They are strengthened by a false belief in stable identity. | |
From: Derek Parfit (Personal Identity [1971], §6) | |
A reaction: This raises some very nice questions, about the extent to which various aspects of self-concern are instinctive and natural, or culturally induced, and even totally misguided and false. I can worry about the distant death of my guinea pig, or my grandson. |
7277 | The perfect man has no self [Zhuangzi (Chuang Tzu)] |
Full Idea: As the saying goes, 'The perfect man has no self' | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.1) | |
A reaction: This seems to be quoted with approval. This is interesting because it implies that lesser beings do have a self, and that having a self is a moral issue, and one which can be controlled. One could, I suppose, concentrate on externals. |
7286 | To see with true clarity, your self must be irrelevant [Zhuangzi (Chuang Tzu)] |
Full Idea: When a man discerns his own self as irrelevant, he sees with true clarity. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.6) | |
A reaction: Seeing 'with clarity' is only one of the ways of seeing, and one mustn't unquestioningly assume that it is the best. Wisdom should contemplate vision with and without the self, and then rise higher and compare the two views. Compare Parfit (Idea 5518). |
5518 | It doesn't matter whether I exist with half my components replaced (any more than an audio system) [Parfit] |
Full Idea: It is quite uninteresting whether, with half its components replaced, I have the same audio system, and also whether I exist if half of my body were simultaneously replaced. | |
From: Derek Parfit (The Unimportance of Identity [1995], p.302) | |
A reaction: It is impossible to deny this, if the part replaced is not the brain. My doubt about Parfit's thesis is that while I may not care whether some modified thing is still me, my lawyers and the police might be very concerned. |
22765 | Wisdom and thought are shared by all things [Empedocles] |
Full Idea: Wisdom and power of thought, know thou, are shared in by all things. | |
From: Empedocles (fragments/reports [c.453 BCE]), quoted by Sextus Empiricus - Against the Logicians (two books) II.286 | |
A reaction: Sextus quotes this, saying that it is 'still more paradoxical', and that it explicitly includes plants. This may mean that Empedocles was not including inanimate matter. |
1524 | For Empedocles thinking is almost identical to perception [Empedocles, by Theophrastus] |
Full Idea: Empedocles assumes that thinking is either identical to or very similar to sense-perception. | |
From: report of Empedocles (fragments/reports [c.453 BCE], A86) by Theophrastus - On the Senses 9 | |
A reaction: Not to be sniffed at. We can, of course, control our thinking (though we can't control the controller) and we contemplate abstractions, but that might be seen as a sort of perception. Vision is not as visual as we think. |
7279 | If words can't be defined, they may just be the chirruping of chicks [Zhuangzi (Chuang Tzu)] |
Full Idea: Our words are not just hot air. Words work because they are something, but the problem is that, if we cannot define a word's meaning, it doesn't really say anything. Can we make a case for it being anything different from the chirruping of chicks? | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: This obviously points us towards Quine's challenge to analyticity, and hence the value of definitions (Ideas 1622 and 1624). Even for Chuang Tzu, it seems naïve to think that you cannot use a word well if you cannot define it. |
23404 | Words are for meaning, and once you have that you can forget the words [Zhuangzi (Chuang Tzu)] |
Full Idea: Words are for meaning: when you've gotten the meaning, you can forget the words. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], 26), quoted by Bryan van Norden - Intro to Classical Chinese Philosophy 9.VI | |
A reaction: 'What exactly did this person say?' 'Don't know, but I've given you the accurate gist'. This is such an obvious phenomenon that I amazed by modern philosophers who deny propositions, or deny meaning entirely. |
552 | Empedocles said good and evil were the basic principles [Empedocles, by Aristotle] |
Full Idea: Empedocles was the first to give evil and good as principles. | |
From: report of Empedocles (fragments/reports [c.453 BCE]) by Aristotle - Metaphysics 985a | |
A reaction: Once you start to think that good and evil will only matter if they have causal powers, it is an easy step to the idea of a benevolent god, and a satanic anti-god. Otherwise the 'principles' could be ignored. |
7283 | Great courage is not violent [Zhuangzi (Chuang Tzu)] |
Full Idea: Great courage is not violent. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: A very nice remark. This, I think, is what the Greeks were struggling to say about courage, but they never quite pinned it down as Chuang Tzu does. |
9762 | We should focus less on subjects of experience, and more on the experiences themselves [Parfit] |
Full Idea: It becomes more plausible, when thinking morally, to focus less upon the person, the subject of experiences, and instead to focus more upon the experiences themselves. | |
From: Derek Parfit (Reasons and Persons [1984], §116) | |
A reaction: This pinpoints how Parfit moves from a view of persons in terms of continuity of consciousness to a utilitarian morality. It brings out nicely what is wrong with utilitarianism - the reductio of a great ball of nice experiences, with no one having them. |
589 | 'Nature' is just a word invented by people [Empedocles] |
Full Idea: Nature is but a word of human framing. | |
From: Empedocles (fragments/reports [c.453 BCE], B008), quoted by Aristotle - Metaphysics 1015a |
21823 | The principle of 'Friendship' in Empedocles is the One, and is bodiless [Empedocles, by Plotinus] |
Full Idea: In Empedocles we have a dividing principle, 'Strife', set against 'Friendship' - which is the One and is to him bodiless, while the elements represent matter. | |
From: report of Empedocles (fragments/reports [c.453 BCE]) by Plotinus - The Enneads 5.1.09 | |
A reaction: The first time I've seen the principle of Love in Empedocles identified with the One of Parmenides. Plotinus is a trustworthy reporter, I think, because he was well read, and had access to lost texts. |
2680 | Empedocles said that there are four material elements, and two further creative elements [Empedocles, by Aristotle] |
Full Idea: Empedocles holds that the corporeal elements are four, but that all the elements, including those which create motion, are six in number. | |
From: report of Empedocles (fragments/reports [c.453 BCE]) by Aristotle - Coming-to-be and Passing-away (Gen/Corr) 314a16 |
6002 | Empedocles says bone is water, fire and earth in ratio 2:4:2 [Empedocles, by Inwood] |
Full Idea: Empedocles used numerical ratios to explain different kinds of matter; for example, bone is two parts water, four parts fire, two parts earth; and blood is an equal blend of all four elements. | |
From: report of Empedocles (fragments/reports [c.453 BCE]) by Brad Inwood - Empedocles | |
A reaction: Why isn't the ration 1:2:1? This presumably shows the influence of Pythagoras (who had also been based in Italy, like Empedocles), as well as that of the earlier naturalistic philosophers. It was a very good theory, though wrong. |
13207 | Fire, Water, Air and Earth are elements, being simple as well as homoeomerous [Empedocles, by Aristotle] |
Full Idea: Empedocles says that Fire, Water, Air and Earth are four elements, and are thus 'simple' rather than flesh, bone and bodies which, like these, are 'homoeomeries'. | |
From: report of Empedocles (fragments/reports [c.453 BCE]) by Aristotle - Coming-to-be and Passing-away (Gen/Corr) 314a26 | |
A reaction: The translation is not quite clear. I take it that flesh and bone may look simple, because they are homoeomerous, but they are not really - but what is his evidence for that? Compare Idea 13208. |
459 | All change is unity through love or division through hate [Empedocles] |
Full Idea: These elements never cease their continuous exchange, sometimes uniting under the influence of Love, so that all become One, at other times again moving apart through the hostile force of Hate. | |
From: Empedocles (fragments/reports [c.453 BCE], B017), quoted by Simplicius - On Aristotle's 'Physics' 158.1- |
13218 | The elements combine in coming-to-be, but how do the elements themselves come-to-be? [Aristotle on Empedocles] |
Full Idea: Empedocles says it is evident that all the other bodies down to the 'elements' have their coming-to-be and their passing-away: but it is not clear how the 'elements' themselves, severally in their aggregated masses, come-to-be and pass-away. | |
From: comment on Empedocles (fragments/reports [c.453 BCE]) by Aristotle - Coming-to-be and Passing-away (Gen/Corr) 325b20 | |
A reaction: Presumably the elements are like axioms - and are just given. How do electrons and quarks come-to-be? |
13225 | Love and Strife only explain movement if their effects are distinctive [Aristotle on Empedocles] |
Full Idea: It is not an adequate explanation to say that 'Love and Strife set things moving', unless the very nature of Love is a movement of this kind and the very nature of Strife a movement of that kind. | |
From: comment on Empedocles (fragments/reports [c.453 BCE]) by Aristotle - Coming-to-be and Passing-away (Gen/Corr) 333b23 | |
A reaction: I take this to be of interest for showing Aristotle's quest for explanations, and his unwillingness to be fobbed off with anything superficial. I take a task of philosophy to be to push explanations further than others wish to go. |
460 | If the one Being ever diminishes it would no longer exist, and what could ever increase it? [Empedocles] |
Full Idea: Besides these elements, nothing else comes into being, nor does anything cease. For if they had been perishing continuously, they would Be no more; and what could increase the Whole? And whence could it have come? | |
From: Empedocles (fragments/reports [c.453 BCE], B017), quoted by Simplicius - On Aristotle's 'Physics' 158.1- |
7280 | As all life is one, what need is there for words? [Zhuangzi (Chuang Tzu)] |
Full Idea: As all life is one, what need is there for words? | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.2) | |
A reaction: In a sense this is nonsense, but it has an appeal. I presume that God would not need words, any more than he would need arithmetic. Life is obviously a complex one, with parts which can be discussed. |
5090 | Maybe bodies are designed by accident, and the creatures that don't work are destroyed [Empedocles, by Aristotle] |
Full Idea: Is it just an accident that teeth and other parts of the body seem to have some purpose, and creatures survive because they happen to be put together in a useful way? Everything else has been destroyed, as Empedocles says of his 'cow with human head'. | |
From: report of Empedocles (fragments/reports [c.453 BCE], 61) by Aristotle - Physics 198b29 | |
A reaction: Good grief! Has no one ever noticed that Empedocles proposed the theory of evolution? It isn't quite natural selection, because we aren't told what does the 'destroying', but it is a little flash of genius that was quietly forgotten. |
461 | God is a pure, solitary, and eternal sphere [Empedocles] |
Full Idea: God is equal in all directions to himself and altogether eternal, a rounded Sphere enjoying a circular solitude. | |
From: Empedocles (fragments/reports [c.453 BCE], B028), quoted by John Stobaeus - Anthology 1.15.2 |
466 | God is pure mind permeating the universe [Empedocles] |
Full Idea: God is mind, holy and ineffable, and only mind, which darts through the whole cosmos with its swift thought. | |
From: Empedocles (fragments/reports [c.453 BCE], B134), quoted by Ammonius - On 'De Interpretatione' 4.5.249.6 |
1719 | In Empedocles' theory God is ignorant because, unlike humans, he doesn't know one of the elements (strife) [Aristotle on Empedocles] |
Full Idea: It is a consequence of Empedocles' view that God is the most unintelligent thing, for he alone is ignorant of one of the elements, namely strife, whereas mortal creatures are familiar with them all. | |
From: comment on Empedocles (fragments/reports [c.453 BCE]) by Aristotle - De Anima 410b08 |
1522 | It is wretched not to want to think clearly about the gods [Empedocles] |
Full Idea: Wretched is he who cares not for clear thinking about the gods. | |
From: Empedocles (fragments/reports [c.453 BCE], B132), quoted by Clement - Miscellanies 5.140.5.1 |
7288 | Go with the flow, and be one with the void of Heaven [Zhuangzi (Chuang Tzu)] |
Full Idea: Don't struggle, go with the flow, and you will find yourself at one with the vastness of the void of Heaven. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.6) | |
A reaction: Ugh. I've got all eternity to do that. The underlying assumption of Taoism seems to be that it is better not to have been born, and if you are thus unfortunate, you should try to pretend that it never happened. Much too negative for my taste. |
7287 | Fish forget about each other in the pond and forget each other in the Tao [Zhuangzi (Chuang Tzu)] |
Full Idea: Fish forget about each other in the pond and forget each other in the Tao. | |
From: Zhuangzi (Chuang Tzu) (The Book of Chuang Tzu [c.329 BCE], Ch.6) | |
A reaction: Strikingly different from Christianity. No wonder Europeans used to describe orientals as 'enigmatic'; the faces of Taoists presumably express indifference. Not for me, I'm afraid. I identify with my fellow humans, because of our shared predicaments. |
