8 ideas
| 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. |
| 21686 | Sense-data are dubious abstractions, with none of the plausibility of tables [Quine] |
| Full Idea: The notion of pure sense datum is a pretty tenuous abstraction, a good deal more conjectural than the notion of an external object, a table or a sheep. | |
| From: Willard Quine (On Mental Entities [1952], p.225) | |
| A reaction: This seems to sum up the view of sense-data held by the generation after Russell and Moore. Ayer still talks about them, but Russell had already given them up. The simple challenge is - what is the evidence for their existence? Cf innate ideas. |
| 21685 | Empiricism says evidence rests on the senses, but that insight is derived from science [Quine] |
| Full Idea: The crucial insight of empiricism is that any evidence for science has its end points in the senses. This insight remains valid, but it is an insight which comes after physics, physiology, and psychology, not before. | |
| From: Willard Quine (On Mental Entities [1952], p.225) | |
| A reaction: Interesting. I think Hume and co. were probably outlining essential presuppositions and contraints which must be accepted by science. Quine offers empiricism as more like a description of science (with success as its authority?). |
| 8114 | The institutional theory says only a competent expert can decree something to be an art work [Dickie, by Gardner] |
| Full Idea: Dickie's institutional theory of art says that something is a work of art if and only if it has had that status conferred on it by a competent member of the artworld. | |
| From: report of George Dickie (Introduction to Aesthetics [1997], Ch.8) by Sebastian Gardner - Aesthetics 3.1 | |
| A reaction: The idea that a single 'competent' person can do this sounds daft, and probably circular. A consensus in the artworld sounds more plausible, but this still leaves the revolutionary genius, who - in retrospect - produced unrecognised 'art'. |
| 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 |
