22334 | Analysis must include definitions, search for simples, concept analysis, and Kant's analysis [Glock] |
Full Idea: Under 'analysis' a minimum would include the Socratic quest for definitions, Descartes' search for simple natures, the empiricists' psychological resolution of complex ideas, and Kant's 'transcendental' analysis of our cognitive capacities. | |
From: Hans-Johann Glock (What is Analytic Philosophy? [2008], 6.1) | |
A reaction: This has always struck me, and I find the narrow focus on modern logic a very distorted idea of the larger project. The aim, I think, is to understand by taking things apart, in the spirit of figuring out how a watch works. |
192 | Only one thing can be contrary to something [Plato] |
Full Idea: To everything that admits of a contrary there is one contrary and no more. | |
From: Plato (Protagoras [c.380 BCE], 332c) | |
A reaction: The sort of thing for which a modern philosopher would demand a proof (and then reject when the proof couldn't be found), where a Greek is happy to assert it as self-evident. I can't think of a counterexample. |
14650 | Maybe proper names involve essentialism [Plantinga] |
Full Idea: Perhaps the notion of a proper name itself involves essentialism. | |
From: Alvin Plantinga (De Re and De Dicto [1969], p.43) | |
A reaction: This is just before Kripke's announcement of 'rigid designation', which seems to have relaunched modern essentialism. The thought is that you can't name something, if you don't have a stable notion of what is (and isn't) being named. |
14648 | Could I name all of the real numbers in one fell swoop? Call them all 'Charley'? [Plantinga] |
Full Idea: Can't I name all the real numbers in the interval (0,1) at once? Couldn't I name them all 'Charley', for example? | |
From: Alvin Plantinga (De Re and De Dicto [1969], p.40) | |
A reaction: Plantinga is nervous about such a sweeping move, but can't think of an objection. This addresses a big problem, I think - that you are supposed to accept the real numbers when we cannot possibly name them all. |
190 | If asked whether justice itself is just or unjust, you would have to say that it is just [Plato] |
Full Idea: If someone asked me 'Is justice itself just or unjust?' I should answer that it was just, wouldn't you? I agree. | |
From: Plato (Protagoras [c.380 BCE], 330c) |
14647 | Surely self-identity is essential to Socrates? [Plantinga] |
Full Idea: If anything is essential to Socrates, surely self-identity is. | |
From: Alvin Plantinga (De Re and De Dicto [1969], p.37) | |
A reaction: This is the modern move of Plantinga and Adams, to make 'is identical with Socrates' the one property which assures the identity of Socrates (his 'haecceity'). My view is that self-identity is not a property. Plantinga wonders about that on p.44. |
14646 | An object has a property essentially if it couldn't conceivably have lacked it [Plantinga] |
Full Idea: An object has a property essentially just in case it couldn't conceivably have lacked that property. | |
From: Alvin Plantinga (De Re and De Dicto [1969], p.35) | |
A reaction: Making it depend on what we can conceive seems a bit dubious, for someone committed to real essences. The key issue is how narrowly or broadly you interpret the word 'property'. The word 'object' needs a bit of thought, too! |
14642 | Expressing modality about a statement is 'de dicto'; expressing it of property-possession is 'de re' [Plantinga] |
Full Idea: Some statements predicate modality of another statement (modality 'de dicto'); but others predicate of an object the necessary or essential possession of a property; these latter express modality 'de re'. | |
From: Alvin Plantinga (De Re and De Dicto [1969], p.26) | |
A reaction: The distinction seems to originate in Aquinas, concerning whether God knows the future (or, how he knows the future). 'De dicto' is straightforward, but possibly the result of convention. 'De re' is controversial, and implies deep metaphysics. |
14643 | 'De dicto' true and 'de re' false is possible, and so is 'de dicto' false and 'de re' true [Plantinga] |
Full Idea: Aquinas says if a 'de dicto' statement is true, the 'de re' version may be false. The opposite also applies: 'What I am thinking of [17] is essentially prime' is true, but 'The proposition "what I am thinking of is prime" is necessarily true' is false. | |
From: Alvin Plantinga (De Re and De Dicto [1969], p.27) | |
A reaction: In his examples the first is 'de re' (about the number), and the second is 'de dicto' (about that proposition). |
14649 | Can we find an appropriate 'de dicto' paraphrase for any 'de re' proposition? [Plantinga] |
Full Idea: To explain the 'de re' via the 'de dicto' is to provide a rule enabling us to find, for each de re proposition, an equivalent de dicto proposition. | |
From: Alvin Plantinga (De Re and De Dicto [1969], p.41) | |
A reaction: Many 'de dicto' paraphrases will change the modality of a 'de re' statement, so the challenge is to find the right equivalent version. Plantinga takes up this challenge. The 'de dicto' statement says the object has the property, and must have it. |
14651 | What Socrates could have been, and could have become, are different? [Plantinga] |
Full Idea: Is there a difference between what Socrates could have been, and what he could have become? | |
From: Alvin Plantinga (De Re and De Dicto [1969], p.44) | |
A reaction: That is, I take it, 1) how different might he have been in the past, given how he is now?, and 2) how different might he have been in the past, and now, if he had permanently diverged from how he is now? 1) has tight constraints on it. |
20184 | The only real evil is loss of knowledge [Plato] |
Full Idea: The only real kind of faring ill is the loss of knowledge. | |
From: Plato (Protagoras [c.380 BCE], 345b) | |
A reaction: This must crucially involve the intellectualist view (of Socrates) that virtuos behaviour results from knowledge, and moral wickedness is the result of ignorance. It is hard to see how forgetting a phone number is evil. |
20185 | The most important things in life are wisdom and knowledge [Plato] |
Full Idea: It would be shameful indeed to say that wisdom and knowledge are anything but the most powerful forces in human activity. | |
From: Plato (Protagoras [c.380 BCE], 352d) | |
A reaction: He lumps wisdom and knowledge together, and I think we can take 'knowledge' to mean something like understanding, because obviously mere atomistic propositional knowledge can be utterly trivial. |
22332 | German and British idealism is not about individual ideas, but the intelligibility of reality [Glock] |
Full Idea: Neither German nor British Idealism reduced reality to episodes in the minds of individuals. Instsead, they insisted that reality is intelligible only because it is a manifestation of a divine spirit or rational principle. | |
From: Hans-Johann Glock (What is Analytic Philosophy? [2008], 5.2) | |
A reaction: They standardly reject Berkeley. Such Idealism seems either to be the design argument for God's existence, or neo-Stoicism (in its claim that nature is rational). Why not just say that nature seems to be intelligible, and stop there? |
191 | Everything resembles everything else up to a point [Plato] |
Full Idea: Everything resembles everything else up to a point. | |
From: Plato (Protagoras [c.380 BCE], 331d) |
22336 | We might say that the family resemblance is just a consequence of meaning-as-use [Glock] |
Full Idea: Against Wittgenstein's family resemblance view one might evoke his own idea that the meaning of a word is its use, and that diversity of use entails diversity of meaning. | |
From: Hans-Johann Glock (What is Analytic Philosophy? [2008], 8.2) | |
A reaction: Wittgenstein might just accept the point. Diversity of concepts reflects diversity of usage. But how do you distinguish 'football is a game' from 'oy, what's your game?'. How does usage distinguish metaphorical from literal (if it does)? |
22335 | The variety of uses of 'game' may be that it has several meanings, and isn't a single concept [Glock] |
Full Idea: The proper conclusion to draw from the fact that we explain 'game' in a variety of different ways is that it is not a univocal term, but has different, albeit related, meanings. | |
From: Hans-Johann Glock (What is Analytic Philosophy? [2008], 8.2) | |
A reaction: [He cites Rundle 1990] Potter says Wittgenstein insisted that 'game' is a single concept. 'Game' certainly slides off into metaphor, as in 'are you playing games with me?'. The multivocal view would still meet family resemblance on a narrower range. |
203 | Courage is knowing what should or shouldn't be feared [Plato] |
Full Idea: Knowledge of what is and is not to be feared is courage. | |
From: Plato (Protagoras [c.380 BCE], 360d) |
202 | No one willingly and knowingly embraces evil [Plato] |
Full Idea: No one willingly goes to meet evil, or what he thinks is evil. | |
From: Plato (Protagoras [c.380 BCE], 358d) | |
A reaction: Presumably people who actively choose satanism can override this deep-seated attitude. But their adherence to evil usually seems to be rather restrained. A danger of tautology with ideas like this. |
193 | Some things are good even though they are not beneficial to men [Plato] |
Full Idea: 'Do you mean by good those things that are beneficial to men?' 'Not only those. I call some things which are not beneficial good as well'. | |
From: Plato (Protagoras [c.380 BCE], 333e) | |
A reaction: Examples needed, but this would be bad news for utilitarians. Good health is not seen as beneficial if it is taken for granted. Not being deaf. |
197 | Some pleasures are not good, and some pains are not evil [Plato] |
Full Idea: There are some pleasures which are not good, and some pains which are not evil. | |
From: Plato (Protagoras [c.380 BCE], 351d) | |
A reaction: Sadism and child birth. Though Bentham (I think) says that there is nothing good about the pain, since the event would obviously be better without it. |
200 | People tend only to disapprove of pleasure if it leads to pain, or prevents future pleasure [Plato] |
Full Idea: The only reason the common man disapproves of pleasures is if they lead to pain and deprive us of future pleasures. | |
From: Plato (Protagoras [c.380 BCE], 354a) | |
A reaction: Plato has a strong sense that some pleasures are just innately depraved and wicked. If those pleasure don't hurt anyone, it is very hard to pinpoint what is wrong with them. |
204 | Socrates is contradicting himself in claiming virtue can't be taught, but that it is knowledge [Plato] |
Full Idea: Socrates is contradicting himself by saying virtue is not teachable, and yet trying to demonstrate that every virtue is knowledge. | |
From: Plato (Protagoras [c.380 BCE], 361b) |
189 | If we punish wrong-doers, it shows that we believe virtue can be taught [Plato] |
Full Idea: Athenians inflict punishment on wrong-doers, which shows that they too think it possible to impart and teach goodness. | |
From: Plato (Protagoras [c.380 BCE], 324c) |
188 | Socrates did not believe that virtue could be taught [Plato] |
Full Idea: Socrates: I do not believe that virtue can be taught. | |
From: Plato (Protagoras [c.380 BCE], 320b) |
