9271 | Human knowledge may not produce well-being; the examined life may not be worth living [Gray] |
Full Idea: Human knowledge is one thing, human well-being another. There is no predetermined harmony between the two. The examined life may not be worth living. | |
From: John Gray (Straw Dogs [2002], 1.9) | |
A reaction: John Gray has set himself up as the Eeyore of modern times, but this point may obviously be correct. Presumably Socrates meant that the examined life was better even if the result was less 'well-being'. Even Gray doesn't want a lobotomy. |
13985 | A true proposition seems true of one fact, but a false proposition seems true of nothing at all. [Ryle] |
Full Idea: Whereas there might be just one fact that a true proposition was like, we would have to say that a false proposition was unlike any fact. We could not speak of the fact that it was false of, so we could not speak of its being false of anything at all. | |
From: Gilbert Ryle (Are there propositions? [1930], 'Objections') | |
A reaction: Ryle brings out very nicely the point Russell emphasised so much, that the most illuminating studies in philosophy are of how falsehood works, rather than of how truths work. If I say 'the Queen is really a man' it is obvious what that is false of. |
13984 | Two maps might correspond to one another, but they are only 'true' of the country they show [Ryle] |
Full Idea: One map of Sussex is like another, but it is not true of that other map, but only of the county. | |
From: Gilbert Ryle (Are there propositions? [1930], 'Objections') | |
A reaction: One might question whether a map is in any sense 'true' of Sussex, though one must admit that there are good and bad maps of Sussex. The point is a nice one, which shows that there is no simple account of truth as correspondence. |
13979 | Logic studies consequence, compatibility, contradiction, corroboration, necessitation, grounding.... [Ryle] |
Full Idea: Logic studies the way in which one thing follows from another, in which one thing is compatible with another, contradicts, corroborates or necessitates another, is a special case of another or the nerve of another. And so on. | |
From: Gilbert Ryle (Are there propositions? [1930], IV) | |
A reaction: I presume that 'and so on' would include how one thing proves another. This is quite a nice list, which makes me think a little more widely about the nature of logic (rather than just about inference). Incompatibility isn't a process. |
17644 | Metaphysical realism is committed to there being one ultimate true theory [Putnam] |
Full Idea: What makes the metaphysical realist a 'metaphysical' realist is his belief that there is somewhere 'one true theory' (two theories which are true and complete descriptions of the world would be mere notational variants of each other). | |
From: Hilary Putnam (Why there isn't a ready-made world [1981], 'Causation') | |
A reaction: This is wrong!!!!! Commitment to one reality doesn't imply that only one comprehensive theory is possible. Theory-making (at least in any human language, or in mathematics) is an inherently limited activity. |
17648 | It is an illusion to think there could be one good scientific theory of reality [Putnam] |
Full Idea: The idea of a coherent theory of the noumena; consistent, systematic, and arrived at by 'the scientific method' seems to me to be chimerical. | |
From: Hilary Putnam (Why there isn't a ready-made world [1981], 'Failure') | |
A reaction: I sort of agree with this, but it definitely doesn't make me an anti-realist. |
13988 | Many sentences do not state facts, but there are no facts which could not be stated [Ryle] |
Full Idea: There are many sentences which do not state facts, while there are no facts which (in principle) could not be stated. | |
From: Gilbert Ryle (Are there propositions? [1930], 'Substitute') | |
A reaction: Hm. This seems like a nice challenge. The first problem would be infinite facts. Then complex universal facts, beyond the cognizance of any mind. Then facts that change faster than thinking can change. Do you give up yet? Then there's.... |
17643 | Shape is essential relative to 'statue', but not essential relative to 'clay' [Putnam] |
Full Idea: Relative to the description 'that statue', a certain shape is an essential property of the object; relative to the description 'that piece of clay', the shape not an essential property (but being clay is). | |
From: Hilary Putnam (Why there isn't a ready-made world [1981], 'Intro') | |
A reaction: Relative to the description 'that loathsome object', is the statue essentially loathsome? Asserting the essence of an object is a response to the object, not a response to a description of it. This is not the solution to the statue problem. |
13983 | Representation assumes you know the ideas, and the reality, and the relation between the two [Ryle] |
Full Idea: The theory of Representative Ideas begs the whole question, by assuming a) that we can know these 'Ideas', b) that we can know the realities they represent, and c) we can know a particular 'idea' to be representative of a particular reality. | |
From: Gilbert Ryle (Are there propositions? [1930], 'Objections') | |
A reaction: Personally I regard the ideas as immediate (rather than acquired by some knowledge process), and I am dimly hoping that they represent reality (or I'm in deep trouble), and I am struggling to piece together the reality they represent. I'm happy with that. |
17642 | The old view that sense data are independent of mind is quite dotty [Putnam] |
Full Idea: Moore and Russell held the strange view that 'sensibilia' (sense data) are mind-independent entities: a view so dotty, on the face of it, that few analytic philosophers like to be reminded that this is how analytic philosophy started. | |
From: Hilary Putnam (Why there isn't a ready-made world [1981], 'Intro') | |
A reaction: I suspect the view was influenced by the anti-psychologism of Frege, and his idea that all the other concepts are mind-independent, living by their own rules in a 'third realm'. Personally I think analytic philosophy needs more psychology, not less. |
9275 | Knowledge does not need minds or nervous systems; it is found in all living things [Gray] |
Full Idea: Knowledge does not need minds, or even nervous systems. It is found in all living things. | |
From: John Gray (Straw Dogs [2002], 2.10) | |
A reaction: I consider it a misnomer to call such things 'knowledge', for which I have much higher standards. Gray is talking about 'information'. Knowledge needs reasons, and possibility of error, not just anticipatory behaviour. |
9276 | The will hardly ever does anything; most of our life just happens to us [Gray] |
Full Idea: We think our actions express our decisions, but in nearly all of our life, willing decides nothing. We cannot wake up or fall asleep, remember or forget our dreams, summon or banish our thoughts, by deciding to do so. | |
From: John Gray (Straw Dogs [2002], 2.12) | |
A reaction: Gray's point does not rule out occasional total control over mental life, but his point is important. The traditional picture is of a life controlled, so the will is seen as at the centre of a person, but it just isn't the case. |
13980 | If you like judgments and reject propositions, what are the relata of incoherence in a judgment? [Ryle] |
Full Idea: Those who find 'judgments' everywhere and propositions nowhere find that some judgments cohere whereas others are incoherent. What is the status of the terms between which these relations hold? | |
From: Gilbert Ryle (Are there propositions? [1930], IV) | |
A reaction: Ryle is playing devil's advocate, but this strikes me as a nice point. I presume Russell after 1906 is the sort of thinker he has in mind. |
13978 | Husserl and Meinong wanted objective Meanings and Propositions, as subject-matter for Logic [Ryle] |
Full Idea: It is argued by Husserl and (virtually) by Meinong that only if there are such entities as objective Meanings - and propositions are just a species of Meaning - is there anything for Logic to be about. | |
From: Gilbert Ryle (Are there propositions? [1930], IV) | |
A reaction: It is presumably this proposal which led to the scepticism about meanings in Wittgenstein, Quine and Kripke. The modern view, which strikes me as right, is that logic is about inference, and so doesn't need a subject-matter. |
13977 | When I utter a sentence, listeners grasp both my meaning and my state of mind [Ryle] |
Full Idea: If I have uttered my sentence aloud, a listener can both understand what I say or grasp my meaning, and also infer to my state of mind. | |
From: Gilbert Ryle (Are there propositions? [1930], I) | |
A reaction: This simple observations seems rather important. If we shake written words onto the floor, they might add up to a proper sentence, but half of the point of a sentence is missing. Irony trades on the gap between meaning and state of mind. |
13976 | 'Propositions' name what is thought, because 'thoughts' and 'judgments' are too ambiguous [Ryle] |
Full Idea: As the orthodox terms 'thoughts' and 'judgments' are equivocal, since they may equally well denote 'thinkings' as 'what-is-thought', the 'accusatives' of acts of thinking have come to be called 'propositions'. | |
From: Gilbert Ryle (Are there propositions? [1930], I) | |
A reaction: I have understood propositions to be capable of truth or falsity. 'What is thought' could be a right old jumble of images and disjointed fragments. Propositions are famous for their unity! |
13981 | Several people can believe one thing, or make the same mistake, or share one delusion [Ryle] |
Full Idea: We ordinarily find no difficulty in saying of a given thing that several people believe it and so, if they think it false, 'make the same mistake' or 'labour under the same delusion'. | |
From: Gilbert Ryle (Are there propositions? [1930], IV) | |
A reaction: Ryle is playing devil's advocate, but this (like 13980) strikes me as quite good support for propositions. I suppose you can describe these phenomena as assent to sentences, but they might be very different sentences to express the same delusion. |
13987 | We may think in French, but we don't know or believe in French [Ryle] |
Full Idea: Although we speak of thinking in French, we never talk of knowing or believing or opining in French. | |
From: Gilbert Ryle (Are there propositions? [1930], 'Substitute') | |
A reaction: Once again Ryle is playing devil's advocate, but he does it rather well, and offers good support for my belief in propositions. I love this. 'I know, in French, a bank where the wild thyme blows'. |
13989 | There are no propositions; they are just sentences, used for thinking, which link to facts in a certain way [Ryle] |
Full Idea: There are no substantial propositions...There is just a relation between grammatical structure and the logical structure of facts. 'Proposition' denotes the same as 'sentence' or 'statement'. A proposition is not what I think, but what I think or talk in. | |
From: Gilbert Ryle (Are there propositions? [1930], 'Conclusions') | |
A reaction: The conclusion of Ryle's discussion, but I found his support for propositions much more convincing than his critique of them, or his attempt at an alternative linguistic account. He never mentioned animals, so he self-evidently hasn't grasped the problem. |
13982 | If we accept true propositions, it is hard to reject false ones, and even nonsensical ones [Ryle] |
Full Idea: All the arguments for the subsistence of true propositions seem to hold good for the subsistence of false ones. We might even have to find room for absurd or nonsensical ones like 'some round squares are not red-headed'. | |
From: Gilbert Ryle (Are there propositions? [1930], 'Objections') | |
A reaction: A particularly nice example of a Category Mistake from the man who made them famous. Why can't we just make belief a proposition attitude, so I equally believe 'sea is blue', 'grass is pink' and 'trees are bifocal', but the status of my belief varies? |
9278 | Nowadays we identify the free life with the good life [Gray] |
Full Idea: We do not value freedom more than people did in earlier times, but we have identified the good life with the chosen life. | |
From: John Gray (Straw Dogs [2002], 3.13) | |
A reaction: Interesting. This is Enlightenment liberalism gradually filtering down into common consciousness, especially via the hegemony of American culture. I sympathise the Gray; don't get me wrong, but I think freedom is overrated. |
17645 | An alien might think oxygen was the main cause of a forest fire [Putnam] |
Full Idea: Imagine a Venusian lands on Earth and observes a forest fire, and says 'I know what caused that - the atmosphere is saturated with oxygen!'. Thus one man's 'background condition' can easily be another man's 'cause'. | |
From: Hilary Putnam (Why there isn't a ready-made world [1981], 'Causation') | |
A reaction: You can't sweep 'the' cause of a fire away so easily. There is always oxygen on Earth, but only occasional forest fires. The oxygen doesn't 'trigger' the fire (i.e. it isn't the proximate cause). |
9280 | Over forty percent of the Earth's living tissue is human [Gray] |
Full Idea: Humans co-opt over forty per cent of the Earth's living tissue. | |
From: John Gray (Straw Dogs [2002], 4.15) | |
A reaction: If you add our domestic animals, I understand that the figure goes up to 95 per cent! I take this to be virtually the only significant ecological fact - population, population, population. Why are there so many cars? So many carbon footprints? |
9272 | Without Christianity we lose the idea that human history has a meaning [Gray] |
Full Idea: For Christians, it is because they occur in history that the lives of humans have a meaning that the lives of other animals do not. ..If we truly leave Christianity behind, we must give up the idea that human history has a meaning. | |
From: John Gray (Straw Dogs [2002], 2.3) | |
A reaction: Interesting. Compare the dispute between 'whig' and 'tory' historians, the former of whom believe that history is going somewhere. |
9279 | What was our original sin, and how could Christ's suffering redeem it? [Gray] |
Full Idea: No one can say what was humankind's original sin, and no one understands how the suffering of Christ can redeem it. | |
From: John Gray (Straw Dogs [2002], 4.1) | |
A reaction: This nicely articulates a problem that has half bothered me, but I have never put into words. I always assumed Eve committed the sin, and Adam cops the blame for not controlling his woman. Dying for our sins has always puzzled me. |
