| 9103 | A universal is not a real feature of objects, but only a thought-object in the mind [William of Ockham] |
| Full Idea: I maintain that a universal is not something real that exists in a subject [of inherence], either inside or outside the mind, but that it has being only as a thought-object in the mind. | |
| From: William of Ockham (Ordinatio [1320], DII Qviii prima redactio) | |
| A reaction: [A footnote says that William later abandoned this view] I don't see a clear distinction here between having real existence in the mind, and being a thought-object in the mind. Maybe we should say 'merely' a thought-object? |
| 8209 | Part of the folk concept of qualia is what makes recognition and comparison possible [Lewis] |
| Full Idea: The concept of qualia (a part of the folk concept) is the concept of properties of experiences apt for causing abilities to recognize and to imagine experiences of the same type. | |
| From: David Lewis (Should a materialist believe in qualia? [1995], p.327) | |
| A reaction: I presume the other part of the folk concept would be what it is about qualia that makes this possible, namely that they 'look/sound/feel.. the same'. Lewis emphasises the functional aspect, which could not possibly be the whole story. |
| 9104 | A universal is the result of abstraction, which is only a kind of mental picturing [William of Ockham] |
| Full Idea: A universal is not the result of generation, but of abstraction, which is only a kind of mental picturing. | |
| From: William of Ockham (Ordinatio [1320], DII Qviii prima redactio) | |
| A reaction: The phrase 'mental picturing' works very plausibly for the universal 'giraffe', but not so well for 'multiplication' or 'contradiction'. Though we might broaden 'picturing' to being a much less visual concept. Mapping seems basic. |
| 16713 | Philosophers are the forefathers of heretics [Tertullian] |
| Full Idea: Philosophers are the forefathers of heretics. | |
| From: Tertullian (works [c.200]), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 20.2 |
| 6610 | I believe because it is absurd [Tertullian] |
| Full Idea: I believe because it is absurd ('Credo quia absurdum est'). | |
| From: Tertullian (works [c.200]), quoted by Robert Fogelin - Walking the Tightrope of Reason n4.2 | |
| A reaction: This seems to be a rather desperate remark, in response to what must have been rather good hostile arguments. No one would abandon the support of reason if it was easy to acquire. You can't deny its engaging romantic defiance, though. |
