6806 | Do not multiply entities beyond necessity [William of Ockham] |
Full Idea: Do not multiply entities beyond necessity. | |
From: William of Ockham (works [1335]) | |
A reaction: This is the classic statement of Ockham's Razor, though it is not found in his printed works. It appears to be mainly aimed at Plato's Theory of Forms. It is taken to refer to types of entities, not numbers. One seraph is as bad as a hundred. |
22132 | Species and genera are individual concepts which naturally signify many individuals [William of Ockham] |
Full Idea: In his mature nominalism, species and genera are identified with certain mental qualities called concepts or intentions of the mind. Ontologically they are individuals too, like everthing else, ...but they naturally signify many different individuals. | |
From: William of Ockham (works [1335]), quoted by Claude Panaccio - William of Ockham p.1056 | |
A reaction: 'Naturally' is the key word, because the concepts are not fictions, but natural responses to encountering individuals in the world. I am an Ockhamist. |
2986 | Belief is the most important propositional attitude [Lyons] |
Full Idea: Belief might be accorded the status of core or chief propositional attitude. | |
From: William Lyons (Approaches to Intentionality [1995], p.126) |
5958 | The sun is always bright; it doesn't become bright when it emerges [Plutarch] |
Full Idea: The sun doesn't become bright when it emerges from the clouds; it always is bright. | |
From: Plutarch (26: Oracles in Decline [c.85], §39) | |
A reaction: Not an argument, but a nice appeal to common sense, like Russell's example of the cat that disappears behind the furniture and then reappears. To disagree with Plutarch here strikes me as the road to philosophical absurdity. |
2978 | Consciousness no longer seems essential to intentionality [Lyons] |
Full Idea: In contrast with Brentano and Husserl, consciousness or attention are no longer seen as essential to intentionality. | |
From: William Lyons (Approaches to Intentionality [1995], Intro) | |
A reaction: This strikes me as being correct, although there seem to be plenty of current philosophers who do not accept it (e.g. Searle). I think philosophy of mind may be stuck in the dark ages if thinkers don't accept this proposal. |
2984 | Perceptions could give us information without symbolic representation [Lyons] |
Full Idea: It is possible to give an account of concept-formation without a language of thought or representation, based on perception, which in the brain seems to involve information without representation. | |
From: William Lyons (Approaches to Intentionality [1995], p.66) | |
A reaction: This claim strikes me as being a little too confident. One might say that a concept IS a representation. However, the perception of several horses might 'blur' together to form a generalised horse. |
2979 | Propositional attitudes require representation [Lyons] |
Full Idea: How else, other than via some form of representational system, could a human organism contain information as a content over which it could operate or 'attitudinise'? | |
From: William Lyons (Approaches to Intentionality [1995], Intro) | |
A reaction: Depends what you mean by 'representational'. In its vaguest sense, this is just a tautology - content must be held in the mind in some form or other, but that tells us nothing. |
2987 | Folk psychology works badly for alien cultures [Lyons] |
Full Idea: It is not easy to employ our folk psychology in the understanding of persons in a very different culture. | |
From: William Lyons (Approaches to Intentionality [1995], p.241) | |
A reaction: This strikes me as a highly significant problem for the friends of folk psychology. It also breaks down in extreme situations, or with mental illness. It seems closer to culture than to brain structure. |
2977 | All thinking has content [Lyons] |
Full Idea: I cannot say I am simply thinking but not thinking about anything. | |
From: William Lyons (Approaches to Intentionality [1995], Intro) | |
A reaction: Hard to disagree. However, I can plausibly reply to 'What are you thinking?' with 'Nothing', if my consciousness is freewheeling. Utterly disconnected content isn't really what we call 'thinking'. |
19381 | The past has ceased to exist, and the future does not yet exist, so time does not exist [William of Ockham] |
Full Idea: Time is composed of non-entities, because it is composed of the past which does not exist now, although it did exist, and of the future, which does not yet exist; therefore time does not exist. | |
From: William of Ockham (works [1335], 6:496), quoted by Richard T.W. Arthur - Leibniz 7 'Nominalist' | |
A reaction: I've a lot of sympathy with this! I favour Presentism, so the past is gone and the future is yet to arrive. But we have no coherent concept of a present moment of any duration to contain reality. We are just completely bogglificated by it all. |
8010 | William of Ockham is the main spokesman for God's commands being the source of morality [William of Ockham] |
Full Idea: The most notable philosopher who makes God's commandment the basis of goodness, rather than God's goodness a reason for obeying him, is William of Occam. | |
From: William of Ockham (works [1335]), quoted by Alasdair MacIntyre - A Short History of Ethics Ch.9 | |
A reaction: Either view has problems. Why choose God to obey? Obey anyone who is powerful? But how do you decide that God is good? How do we know the nature of God's commands, or the nature of God's goodness? Etc. |
16679 | Even an angel must have some location [William of Ockham, by Pasnau] |
Full Idea: Ockham dismisses the possibility of non-location out of hand, remarking that even an angel has some location. | |
From: report of William of Ockham (works [1335]) by Robert Pasnau - Metaphysical Themes 1274-1671 14.4 |
