14974 | A relation is 'Euclidean' if aRb and aRc imply bRc [Cresswell] |
Full Idea: A relation is 'Euclidean' if aRb and aRc imply bRc. | |
From: Max J. Cresswell (Modal Logic [2001], 7.1.2) | |
A reaction: If a thing has a relation to two separate things, then those two things will also have that relation between them. If I am in the same family as Jim and as Jill, then Jim and Jill are in the same family. |
11946 | Propensities are part of a situation, not part of the objects [Popper] |
Full Idea: Propensities should not be regarded as inherent in an object, such as a die or a penny, but should be regarded as inherent in a situation (of which, of course, the object was part). | |
From: Karl Popper (A World of Propensities [1993], p.14), quoted by George Molnar - Powers 6.2 | |
A reaction: Molnar argues against this claim, and I agree with him. We can see why Popper might prefer this relational view, given that powers often only become apparent in unusual relational situations. |
