| 8910 | General and universal are not real entities, but useful inventions of the mind, concerning words or ideas [Locke] |
| Full Idea: It is plain that general and universal belong not to the real existence of things; but are the inventions and creatures of the understanding, made by it for its own use, and concern only signs, whether words or ideas. | |
| From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 3.03.11) | |
| A reaction: Frege and Geach viciously attacked this view, and it seems to be discredited, but I think it is time for a revival, given that the alternative view seems to lead to platonism. I take the first step in mental abstractionism to be pre-verbal. |
| 12554 | Existences can only be known by experience [Locke] |
| Full Idea: The existence of things is to be known only from experience. | |
| From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 4.03.31) | |
| A reaction: This is the clearest statement you could wish for of the standard empiricist view of such things. Locke might take a broad view of experience, since he unshakably infers the existence of God from merely thinking about being. |
| 5992 | Chrysippus says action is the criterion for existence, which must be physical [Chrysippus, by Tieleman] |
| Full Idea: Chrysippus regarded power to act and be acted upon as the criterion for existence or being - a test satisfied by bodies alone. | |
| From: report of Chrysippus (fragments/reports [c.240 BCE]) by Teun L. Tieleman - Chrysippus | |
| A reaction: This defines existence in terms of causation. Is he ruling out a priori a particle (say) which exists, but never interacts with anything? If so, he is inclining towards anti-realism. |
