11211 | If a sound conclusion comes from two errors that cancel out, the path of the argument must matter [Rumfitt] |
Full Idea: If a designated conclusion follows from the premisses, but the argument involves two howlers which cancel each other out, then the moral is that the path an argument takes from premisses to conclusion does matter to its logical evaluation. | |
From: Ian Rumfitt ("Yes" and "No" [2000], II) | |
A reaction: The drift of this is that our view of logic should be a little closer to the reasoning of ordinary language, and we should rely a little less on purely formal accounts. |
11210 | Standardly 'and' and 'but' are held to have the same sense by having the same truth table [Rumfitt] |
Full Idea: If 'and' and 'but' really are alike in sense, in what might that likeness consist? Some philosophers of classical logic will reply that they share a sense by virtue of sharing a truth table. | |
From: Ian Rumfitt ("Yes" and "No" [2000]) | |
A reaction: This is the standard view which Rumfitt sets out to challenge. |
11212 | The sense of a connective comes from primitively obvious rules of inference [Rumfitt] |
Full Idea: A connective will possess the sense that it has by virtue of its competent users' finding certain rules of inference involving it to be primitively obvious. | |
From: Ian Rumfitt ("Yes" and "No" [2000], III) | |
A reaction: Rumfitt cites Peacocke as endorsing this view, which characterises the logical connectives by their rules of usage rather than by their pure semantic value. |
2170 | Homer does not distinguish between soul and body [Homer, by Williams,B] |
Full Idea: Homer's descriptions of people did without a dualistic distinction between soul and body. | |
From: report of Homer (The Iliad [c.850 BCE]) by Bernard Williams - Shame and Necessity II - p.23 |
11214 | We learn 'not' along with affirmation, by learning to either affirm or deny a sentence [Rumfitt] |
Full Idea: The standard view is that affirming not-A is more complex than affirming the atomic sentence A itself, with the latter determining its sense. But we could learn 'not' directly, by learning at once how to either affirm A or reject A. | |
From: Ian Rumfitt ("Yes" and "No" [2000], IV) | |
A reaction: [compressed] This seems fairly anti-Fregean in spirit, because it looks at the psychology of how we learn 'not' as a way of clarifying what we mean by it, rather than just looking at its logical behaviour (and thus giving it a secondary role). |
2171 | The 'will' doesn't exist; there is just conclusion, then action [Homer, by Williams,B] |
Full Idea: Homer left out another mental action lying between coming to a conclusion and acting on it; and he did well, since there is no such action, and the idea is the invention of bad philosophy. | |
From: report of Homer (The Iliad [c.850 BCE]) by Bernard Williams - Shame and Necessity II - p.37 | |
A reaction: This is a characteristically empiricist view, which is found in Hobbes. The 'will' seems to have a useful role in folk psychology. We can at least say that coming to a conclusion that I should act, and then actually acting, are not the same thing. |
6968 | Some people think there are ethical facts, but of a 'queer' sort [Ayer] |
Full Idea: If someone wishes to say that ethical statements are statements of fact, only it is a queer sort of fact, he is welcome to do so. | |
From: A.J. Ayer (On the analysis of moral judgements [1949], p.233) | |
A reaction: The word 'queer' was picked up by Mackie and developed into his error theory, that moral facts are a misunderstanding. Personally I think that moral facts might be teleological facts, but that is rather hard to demonstrate. |
6972 | A right attitude is just an attitude one is prepared to stand by [Ayer] |
Full Idea: Asking whether the attitude that one has adopted is the right attitude comes down to asking whether one is prepared to stand by it. | |
From: A.J. Ayer (On the analysis of moral judgements [1949], p.244) | |
A reaction: I would have thought that someone who persisted in being ruthlessly selfish might nevertheless distinguish their behaviour from the grudging concession that the 'right' thing to do might be quite different. |
6973 | Moral theories are all meta-ethical, and are neutral as regards actual conduct [Ayer] |
Full Idea: All moral theories, intuitionist, naturalistic, objectivist, emotive, and the rest, in so far as they are philosophical theories, are neutral as regards actual conduct; they belong to the field of meta-ethics, not ethics proper. | |
From: A.J. Ayer (On the analysis of moral judgements [1949]) | |
A reaction: Interestingly, Ayer doesn't seem willing to accept 'ethics proper' as being 'philosophical'. Given the modern rise of applied ethics, it seems suprising to say that even normative ethics is not philosophical. Utilitarianism seems not to be philosophical. |
6974 | Moral judgements cannot be the logical consequence of a moral philosophy [Ayer] |
Full Idea: A moral philosopher will have his moral standards and will sometimes make moral judgements, but these moral judgements cannot be a logical consequence of his philosophy. | |
From: A.J. Ayer (On the analysis of moral judgements [1949], p.247) | |
A reaction: I take this to be an assertion of the is-ought distinction. Personally this strikes me as totally false. Ayer needs to think more deeply about moral philosophy! |
6971 | I would describe intuitions of good as feelings of approval [Ayer] |
Full Idea: I suspect that the experiences which some philosophers want to describe as intuitions, or a quasi-sensory apprehensions, of good are not significantly different from those that I want to describe as feelings of approval. | |
From: A.J. Ayer (On the analysis of moral judgements [1949], p.239) | |
A reaction: This is the standard ground for rejecting intuitionism, along with the point that even if intuitions are not just feelings of approval, it seems impossible to tell the difference. |
6969 | Approval of historical or fictional murders gives us leave to imitate them [Ayer] |
Full Idea: In saying that Brutus or Raskolnikov acted rightly, I am giving myself and others leave to imitate them should similar circumstances arise. | |
From: A.J. Ayer (On the analysis of moral judgements [1949], p.237) | |
A reaction: This seems to be a reply to the Frege-Geach Problem, of why we have emotional attitudes to crimes that mean nothing to us. Such crimes, however, involve our virtues, and don't depend on awaiting 'similar circumstances'. |
6970 | Moral judgements are not expressions, but are elements in a behaviour pattern [Ayer] |
Full Idea: To say, as I once did, that moral judgements are merely expressive of certain feelings is an oversimplification; ..moral attitudes consist in certain patterns of behaviour, and the expression of a judgement is an element in the pattern. | |
From: A.J. Ayer (On the analysis of moral judgements [1949], p.238) | |
A reaction: This seems to switch from emotivism to what Frank Jackson calls 'moral functionalism', where morality is what gets us from certain emotional responses to willed actions. This strikes me, like most functional explanations, as wrong. |
21819 | Plato says the Good produces the Intellectual-Principle, which in turn produces the Soul [Homer, by Plotinus] |
Full Idea: In Plato the order of generation is from the Good, the Intellectual-Principle; from the Intellectual-Principle, the Soul. | |
From: report of Homer (The Iliad [c.850 BCE], 509b) by Plotinus - The Enneads 5.1.08 | |
A reaction: The doctrine of Plotinus merely echoes Plato, in that case, except that the One replaces the Form of the Good. Does this mean that what is first in Plotinus is less morally significant, and more concerned with reason and being? |
11388 | Let there be one ruler [Homer] |
Full Idea: The rule of many is not good; let there be one ruler. | |
From: Homer (The Iliad [c.850 BCE], 2.204), quoted by Vassilis Politis - Aristotle and the Metaphysics 8.9 | |
A reaction: [Quoted by Aristotle at Metaphysics 1076a04] |
14829 | Homer so enjoys the company of the gods that he must have been deeply irreligious [Homer, by Nietzsche] |
Full Idea: Homer is so at home among his gods, and takes such delight in them as a poet, that he surely must have been deeply irreligious. | |
From: report of Homer (The Iliad [c.850 BCE]) by Friedrich Nietzsche - Human, All Too Human 125 | |
A reaction: Blake made a similar remark about where the true allegiance of Milton lay in 'Paradise Lost'. |
