| 13786 | Wisdom is called 'beautiful', because it performs fine works [Plato] |
| Full Idea: Wisdom [phronesis] is correctly given the name 'kalon' [beautiful], since it performs the works that we say are beautiful and welcome as such. | |
| From: Plato (Cratylus [c.377 BCE], 416d) | |
| A reaction: 'Phronesis' in Aristotle is more like prudence, or common sense, rather than wisdom ['sophia']. 'Kalon' also means fine or noble. This translation seems fair enough, though. |
| 13780 | Good people are no different from wise ones [Plato] |
| Full Idea: Socrates: Are good people any different from wise ones? No, they aren't. | |
| From: Plato (Cratylus [c.377 BCE], 398b) | |
| A reaction: This is Socrates's 'intellectualism', his view that being good is entirely a matter of reason and knowledge, and not a matter of habit or emotion. Do we still accept the traditional assumption that wise people are thereby morally good? |
| 13778 | A dialectician is someone who knows how to ask and to answer questions [Plato] |
| Full Idea: What would you call someone who knows how to ask and answer questions? Wouldn't you call him a dialectician? | |
| From: Plato (Cratylus [c.377 BCE], 390c) | |
| A reaction: Asking good questions and giving good answers sound like two very different skills. I presume dialectic is the process of arriving at answers by means of asking the right questions. |
| 13776 | Truths say of what is that it is, falsehoods say of what is that it is not [Plato] |
| Full Idea: Those statements that say of the things that are that they are, are true, while those that say of the things that are that they are not, are false. | |
| From: Plato (Cratylus [c.377 BCE], 385b) | |
| A reaction: It was quite a shock to discover this, because the famous Aristotle definition (Idea 586) is always quoted, and no modern writers seem to have any awareness of the Plato remark. Classical scholarship is very poor in analytic philosophy. |
| 13777 | A name is a sort of tool [Plato] |
| Full Idea: A name is a sort of tool. | |
| From: Plato (Cratylus [c.377 BCE], 388a) | |
| A reaction: Idea 13775 gives a background for this metaphor, from earlier in the text. Wittgenstein has a famous toolkit metaphor for language. The whole of this text, 'Cratylus', is about names. |
| 13790 | A name-giver might misname something, then force other names to conform to it [Plato] |
| Full Idea: The name-giver might have made a mistake at the beginning and then forced the other names to be consistent with it. | |
| From: Plato (Cratylus [c.377 BCE], 436c) | |
| A reaction: Lovely. This is Gareth Evans's 'Madagascar' example. See Idea 9041. |
| 13791 | Things must be known before they are named, so it can't be the names that give us knowledge [Plato] |
| Full Idea: If things cannot be learned except from their names, how can we possibly claim that the name-givers or rule-setters have knowledge before any names had been given for them to know? | |
| From: Plato (Cratylus [c.377 BCE], 438b) | |
| A reaction: Running through this is a hostility to philosophy of language, so I find it very congenial. We are animals who relate to the world before language takes a grip. We have full-blown knowledge of things, with no intervention of words. |
| 13789 | Anyone who knows a thing's name also knows the thing [Plato] |
| Full Idea: The simple truth is that anyone who knows a thing's name also knows the thing. | |
| From: Plato (Cratylus [c.377 BCE], 435d) | |
| A reaction: A nice slogan, but it seems to be blatantly false. The best example is Gareth Evans's of joining in a conversation about a person ('Louis'?), and only gradually tuning in to the person to which the name refers. |
| 2063 | How can beauty have identity if it changes? [Plato] |
| Full Idea: If beauty never stays the same, how can it be something? | |
| From: Plato (Cratylus [c.377 BCE], 439e) |
| 13775 | We only succeed in cutting if we use appropriate tools, not if we approach it randomly [Plato] |
| Full Idea: If we undertake to cut something and make the cut in whatever way we choose and with whatever tool we choose, we will not succeed. If we cut according to the nature of cutting and being cut, and with the natural tool, we'll succeed and cut correctly. | |
| From: Plato (Cratylus [c.377 BCE], 387a) | |
| A reaction: I take this passage to be the creed for realists about the physical world - a commitment not merely to the existence of an external world, but to the existence of facts about it, which we may or may not be able to discover. |
| 13787 | Doesn't each thing have an essence, just as it has other qualities? [Plato] |
| Full Idea: Don't you think that just as each thing has a colour or some of those other qualities we mentioned, it also has a being or essence? | |
| From: Plato (Cratylus [c.377 BCE], 423e) | |
| A reaction: The Greek here seems to be 'ousia', which I increasingly think should be translated as 'distinct identity', rather than as 'existence' or as 'essence'. Maybe the philosophical term 'haecceity' captures it best. |
| 13774 | Things don't have every attribute, and essence isn't private, so each thing has an essence [Plato] |
| Full Idea: If Euthydemus is wrong that everything always has every attribute simultaneously, or that being or essence is private for each person, then it is clear that things have some fixed being or essence of their own. | |
| From: Plato (Cratylus [c.377 BCE], 386d) | |
| A reaction: I'm not sure what 'being or essence' translates. If it translates 'ousia' then I wouldn't make too much of this remark from an essentialist point of view. |
| 13772 | Is the being or essence of each thing private to each person? [Plato] |
| Full Idea: Is the being or essence of each of the things that are something private to each person, as Protagoras tells us? | |
| From: Plato (Cratylus [c.377 BCE], 385e) | |
| A reaction: This kind of drastic personal relativism about essences doesn't sound very plausible, but the idea that essences are private to each culture, or to each language, must certainly be taken seriously. |
| 13788 | If we made a perfect duplicate of Cratylus, there would be two Cratyluses [Plato] |
| Full Idea: Soc: Suppose we made a duplicate of everything you have and put it beside you; would there then be two Cratyluses, or Cratylus and an image of Cratylus? Crat: It seems to me, Socrates, that there would be two Cratyluses. | |
| From: Plato (Cratylus [c.377 BCE], 432c) | |
| A reaction: Don't think that science fiction examples are a modern development in philosophy. Plato has just invented the Startrek transporter. The two Cratyluses are the two spheres in Max Black's famous example. |
| 13792 | There can't be any knowledge if things are constantly changing [Plato] |
| Full Idea: It isn't even reasonable to say that there is such a thing as knowledge, Cratylus, if all things are passing on and none remain. | |
| From: Plato (Cratylus [c.377 BCE], 440a) | |
| A reaction: This encapsulates Plato's horror at Heraclitus scepticism about the stable identity of things. It leads to the essentialism of Aristotle and Leibniz, who fear that there is no knowledge if we can't pin down individual identities. Know processes? |
| 13781 | Soul causes the body to live, and gives it power to breathe and to be revitalized [Plato] |
| Full Idea: Those who named the soul thought that when the soul is present in the body, it causes it to live and gives it the power to breathe the air and be revitalized [anapsuchon]. | |
| From: Plato (Cratylus [c.377 BCE], 399d) | |
| A reaction: I quote this to emphasis that Greek psuché is very different from the consciousness which is largely discussed in modern philosophy of mind. I find it helpful to make a real effort to grasp the Greek concept. The feeling of life within you. |
| 23514 | The cerbellum has a huge number of neurons, but little involvement in consciousness [Seth] |
| Full Idea: The cerebellum [at the back] has about four times as many neurons as the rest of the brain put together, but seems barely involved in consciousness. | |
| From: Anil Seth (Being You [2021], I.2) | |
| A reaction: I wonder if it also has four times as many connections? |
| 23513 | Single neurons can carry out complex functions [Seth] |
| Full Idea: It is increasingly apparent that even single neurons are capable of carrying out highly complex functions all by themselves. | |
| From: Anil Seth (Being You [2021], I.1 n) | |
| A reaction: Bang goes the simple connectionist account of consciousness. |
| 23516 | Maybe a system is conscious if the whole generates more information than its parts [Seth] |
| Full Idea: The main claim of Tononi's 'integrated information theory' is that a system is conscious to the extent that its whole generates more information than its parts. | |
| From: Anil Seth (Being You [2021], I.3) | |
| A reaction: Seth seems to present this as an 'interesting' proposal. I find it unlikely that consciousness could be explain in terms of information, or that a machine constructed on this principle would thus become conscious. (Databases pass this test). |
| 23519 | The self is embodied, perspectival, volitional, narrative and social [Seth, by PG] |
| Full Idea: The elements of a self are 1) embodied - related directly to the body, 2) perspectival - having a viewpoint, 3) volitional - being an agent, 4) narrative - aware of past and future, and 5) social - as others perceive me. | |
| From: report of Anil Seth (Being You [2021], III.8) by PG - Db (ideas) | |
| A reaction: [summarised] Seth says there are distinctive emotions associated with each of these aspects of the self. This list is very helpful, as a discouragement for anyone who wants to pick one of these as the sole true nature of the self. |
| 23518 | Modern AI is mostly machine-based pattern recognition [Seth] |
| Full Idea: Much of today's AI is best described as sophisticated machine-based pattern recognition. | |
| From: Anil Seth (Being You [2021], IV.13) | |
| A reaction: Personally I wouldn't want to underestimate the extent to which human intelligence is also pattern recognition (across time as well as in space). |
| 23517 | Volition is felt as doing what you want, with possible alternatives, and a source from within [Seth] |
| Full Idea: The experience of volition is defined by 1) the feeling that I am doing what I want to do, 2) that I could have done otherwise, and 3) that voluntary actions seem to come from within. | |
| From: Anil Seth (Being You [2021], III.11) | |
| A reaction: Note that these can all be cited without reference to their feeling 'free'. |
| 468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
| Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
| From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
| 23515 | Human exceptionalism plagues biology, and most other human thinking [Seth] |
| Full Idea: Human exceptionalism has repeatedly plagued biology, and has darkened the history of human thought everywhere. | |
| From: Anil Seth (Being You [2021], I.2) | |
| A reaction: I increasingly agree with this, as much in philosophy as in biology. We really need to get used to our place in evolution. |
| 13785 | 'Arete' signifies lack of complexity and a free-flowing soul [Plato] |
| Full Idea: 'Areté' signifies lack of perplexity [euporia, ease of movement], and that the flow of a good soul is unimpeded. | |
| From: Plato (Cratylus [c.377 BCE], 415d) | |
| A reaction: Some highly dubious etymology going on here, and throughout 'Cratylus', but it gives a nice feeling for the way Socrates and Plato saw virtue. |
| 13779 | The natural offspring of a lion is called a 'lion' (but what about the offspring of a king?) [Plato] |
| Full Idea: It seems to me that it is right to call a lion's offspring a 'lion' and a horse's offspring a 'horse' (I'm talking about natural offspring, not some monster). ...but by the same argument any offspring of a king should be called a 'king'. | |
| From: Plato (Cratylus [c.377 BCE], 393b) | |
| A reaction: The standard modern difficulty is whether all descendants of dinosaurs are still called 'dinosaur', which they are not. |
| 13783 | Even the gods love play [Plato] |
| Full Idea: Even the gods love play. | |
| From: Plato (Cratylus [c.377 BCE], 406c) |
