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. |
9331 | How do we determine which of the sentences containing a term comprise its definition? [Horwich] |
Full Idea: How are we to determine which of the sentences containing a term comprise its definition? | |
From: Paul Horwich (Stipulation, Meaning and Apriority [2000], §2) | |
A reaction: Nice question. If I say 'philosophy is the love of wisdom' and 'philosophy bores me', why should one be part of its definition and the other not? What if I stipulated that the second one is part of my definition, and the first one isn't? |
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) | |
A reaction: A rather Platonic question! I presume that Heraclitus had a sense of beauty, and things regarded as 'sublime' are often tumultuous. |
21598 | Austin revealed many meanings for 'vague': rough, ambiguous, general, incomplete... [Austin,JL, by Williamson] |
Full Idea: Austin's account brought out the variety of features covered by 'vague' in different contexts: roughness, ambiguity, imprecision, lack of detail, generality, inaccuracy, incompleteness. Even 'vague' is vague. | |
From: report of J.L. Austin (Sense and Sensibilia [1962], p.125-8) by Timothy Williamson - Vagueness 3.1 | |
A reaction: Some of these sound the same. Maybe Austin distinguishes them. |
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. |
9333 | A priori belief is not necessarily a priori justification, or a priori knowledge [Horwich] |
Full Idea: It is one thing to believe something a priori and another for this belief to be epistemically justified. The latter is required for a priori knowledge. | |
From: Paul Horwich (Stipulation, Meaning and Apriority [2000], §8) | |
A reaction: Personally I would agree with this, because I don't think anything should count as knowledge if it doesn't have supporting reasons, but fans of a priori knowledge presumably think that certain basic facts are just known. They are a priori justified. |
9342 | Understanding needs a priori commitment [Horwich] |
Full Idea: Understanding is itself based on a priori commitment. | |
From: Paul Horwich (Stipulation, Meaning and Apriority [2000], §12) | |
A reaction: This sounds plausible, but needs more justification than Horwich offers. This is the sort of New Rationalist idea I associate with Bonjour. The crucial feature of the New lot is, I take it, their fallibilism. All understanding is provisional. |
9332 | Meaning is generated by a priori commitment to truth, not the other way around [Horwich] |
Full Idea: Our a priori commitment to certain sentences is not really explained by our knowledge of a word's meaning. It is the other way around. We accept a priori that the sentences are true, and thereby provide it with meaning. | |
From: Paul Horwich (Stipulation, Meaning and Apriority [2000], §8) | |
A reaction: This sounds like a lovely trump card, but how on earth do you decide that a sentence is true if you don't know what it means? Personally I would take it that we are committed to the truth of a proposition, before we have a sentence for it. |
9341 | Meanings and concepts cannot give a priori knowledge, because they may be unacceptable [Horwich] |
Full Idea: A priori knowledge of logic and mathematics cannot derive from meanings or concepts, because someone may possess such concepts, and yet disagree with us about them. | |
From: Paul Horwich (Stipulation, Meaning and Apriority [2000], §12) | |
A reaction: A good argument. The thing to focus on is not whether such ideas are a priori, but whether they are knowledge. I think we should employ the word 'intuition' for a priori candidates for knowledge, and demand further justification for actual knowledge. |
9334 | If we stipulate the meaning of 'number' to make Hume's Principle true, we first need Hume's Principle [Horwich] |
Full Idea: If we stipulate the meaning of 'the number of x's' so that it makes Hume's Principle true, we must accept Hume's Principle. But a precondition for this stipulation is that Hume's Principle be accepted a priori. | |
From: Paul Horwich (Stipulation, Meaning and Apriority [2000], §9) | |
A reaction: Yet another modern Quinean argument that all attempts at defining things are circular. I am beginning to think that the only a priori knowledge we have is of when a group of ideas is coherent. Calling it 'intuition' might be more accurate. |
9339 | A priori knowledge (e.g. classical logic) may derive from the innate structure of our minds [Horwich] |
Full Idea: One potential source of a priori knowledge is the innate structure of our minds. We might, for example, have an a priori commitment to classical logic. | |
From: Paul Horwich (Stipulation, Meaning and Apriority [2000], §11) | |
A reaction: Horwich points out that to be knowledge it must also say that we ought to believe it. I'm wondering whether if we divided the whole territory of the a priori up into intuitions and then coherent justifications, the whole problem would go away. |
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. |
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) |
