| 15542 | All possibilities are recombinations of properties in the actual world [Armstrong, by Lewis] |
| Full Idea: Armstrong's thesis is that recombination gives all the possibilities there are. There is no 'outer sphere' of possibilities wherein are found new and different universals alien to the actual world. No extra fundamental properties of fundamental particles. | |
| From: report of David M. Armstrong (A Combinatorial Theory of Possibility [1989]) by David Lewis - Armstrong on combinatorial possibility 'Combinatorialism' | |
| A reaction: I can't grasp what Armstrong's basis would be for such a claim. I surmise that current fundamental particles can only have the properties they currently have, but I can't see the impossibility of new stuff with new properties. |
| 16978 | If conceivability is a priori coherence, that implies possibility [Tahko] |
| Full Idea: Maybe conceivability could be understood as a priori coherence, which implies possibility. | |
| From: Tuomas E. Tahko (The Epistemology of Essence (draft) [2013], 3.2) | |
| A reaction: I'm not quite sure why 'a priori' has to be there. Assessing conceivability just is assessing coherence. That couches it as a rational activity, rather than as a purely imaginary one. Trying to conceive a square circle isn't just daydreaming. |
