| 6564 | To affirm 'p and not-p' is to have mislearned 'and' or 'not' [Quine] |
| Full Idea: To affirm a compound of the form 'p and not-p' is just to have mislearned one or both of these particles. | |
| From: Willard Quine (From Stimulus to Science [1995], p.23), quoted by Robert Fogelin - Walking the Tightrope of Reason Ch.1 | |
| A reaction: Quoted by Fogelin. This summarises the view of logic developed by the young Wittgenstein, that logical terms are 'operators', rather than referring terms. Of course the speaker may have a compartmentalised mind, or not understand 'p' properly. |
| 16661 | There are two sorts of category - referring to things, and to circumstances of things [Boethius] |
| Full Idea: Is it not now clear what the difference is between items in the categories? Some serve to refer to a thing, whereas others serve to refer to the circumstances of a thing. | |
| From: Boethius (Concerning the Trinity [c.518], Ch. 4), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 12.5 |
| 20643 | Consilience is a common groundwork of explanation [Whewell] |
| Full Idea: Consilience is the jumping together of knowledge by the linking of facts and fact-based theory across disciplines to create a common groundwork of explanation. | |
| From: William Whewell (The Philosophy of the Inductive Sciences [1840]), quoted by Peter Watson - Convergence Intro 'United' | |
| A reaction: Apparently this is the first use of the word, which was popularised by E.O. Wilson in recent times. If, as I do, you dream of a final theory, in philosophy as well as in science, then you have to be a fan of consilience. |
