527 | Everything exists which anyone perceives [Metrodorus of Chios] |
Full Idea: Everything exists which anyone perceives. | |
From: Metrodorus (Chi) (Natural Science (lost) [c.340 BCE], B2), quoted by (who?) - where? | |
A reaction: cf Berkeley and Epicurus. This misses out the problem of perceptual error, such as a square tower looking round from a distance, or one person in a group thinking they have seen something. It is still a good criterion, though! |
8946 | We could make our intuitions about heaps precise with a million-valued logic [Fisher] |
Full Idea: We could construct a 1,000,000-valued logic that would allow our intuitions concerning a heap to vary exactly with the amount of sand in the heap. | |
From: Jennifer Fisher (On the Philosophy of Logic [2008]) | |
A reaction: Presumably only an infinite number of grains of sand would then produce a true heap, and even one grain would count as a bit of a heap, which must both be wrong, so I can't see this helping much. |
