| 1875 | Dogs show reason in decisions made by elimination [Chrysippus, by Sext.Empiricus] |
| Full Idea: A dog makes use of the fifth complex indemonstrable syllogism when, arriving at a spot where three ways meet, after smelling at two roads by which the quarry did not pass, he rushes off at once by the third without pausing to smell. | |
| From: report of Chrysippus (fragments/reports [c.240 BCE]) by Sextus Empiricus - Outlines of Pyrrhonism I.69 | |
| A reaction: As we might say: either A or B or C; not A; not B; therefore C. I wouldn't want to trust this observation without a lot of analysis of slow-motion photography of dogs as crossroads. Even so, it is a nice challenge to Descartes' view of animals. |
| 18525 | Mental abstraction does not make what is abstracted mind-dependent [Heil] |
| Full Idea: Talk of abstraction and 'partial consideration' (Locke) does not make what is abstracted mind-dependent. In abstracting, you attend to what is there to be considered. | |
| From: John Heil (The Universe as We Find It [2012], 05.7) | |
| A reaction: Quite so. The point is to focus on aspects of reality. Does anyone seriously doubt that reality has 'aspects'? |
| 18504 | Only particulars exist, and generality is our mode of presentation [Heil] |
| Full Idea: Existing things are particular, and generality is a feature of our ways of representing the universe. | |
| From: John Heil (The Universe as We Find It [2012], 01.1) | |
| A reaction: This is right, and expressed with beautiful simplicity. How could anyone disagree with this? But they do! |
