7529 | All philosophy should begin with an analysis of propositions [Russell] |
Full Idea: That all sound philosophy should begin with an analysis of propositions is a truth too evident, perhaps, to demand a proof. | |
From: Bertrand Russell (The Philosophy of Leibniz [1900], p.8), quoted by Ray Monk - Bertrand Russell: Spirit of Solitude | |
A reaction: Compare Idea 483. The obvious response to Russell is that it must actually begin with a decision about which propositions are worth analysing - and that ain't easy. I like analysis, but philosophy is also a vision of truth. |
11966 | If there are essential properties, how do you find out what they are? [Chisholm] |
Full Idea: It seems to me that if Adam does have essential properties, there is no procedure at all for finding out what they are. | |
From: Roderick Chisholm (Identity through Possible Worlds [1967], p.85) | |
A reaction: My tentative suggestion is that the essential properties are those which explain the nature, power, function and role of Adam in the 'actual' world. Whatever possibilities he acquires, he had better retain the capacity to be the First Man. |
11965 | Could possible Adam gradually transform into Noah, and vice versa? [Chisholm] |
Full Idea: If Adam lived for 931 years in a possible world, instead of his actual 930 years, ..then Adam and Noah could gradually exchange their ages and other properties...and we could trace Adam in a world back to the actual Noah, and vice versa. | |
From: Roderick Chisholm (Identity through Possible Worlds [1967], p.81-2) | |
A reaction: [very compressed] Chisholm was one of the first to raise this problem for possible worlds, though it had been Quine's objection to modal logic all along. Only Adam having essential properties seems to stop this slippery slope, says Chisholm. |
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. |
