19381 | The past has ceased to exist, and the future does not yet exist, so time does not exist [William of Ockham] |
Full Idea: Time is composed of non-entities, because it is composed of the past which does not exist now, although it did exist, and of the future, which does not yet exist; therefore time does not exist. | |
From: William of Ockham (works [1335], 6:496), quoted by Richard T.W. Arthur - Leibniz 7 'Nominalist' | |
A reaction: I've a lot of sympathy with this! I favour Presentism, so the past is gone and the future is yet to arrive. But we have no coherent concept of a present moment of any duration to contain reality. We are just completely bogglificated by it all. |
14098 | An acid is just a proton donor [Rosen] |
Full Idea: To be an acid just is to be a proton donor. | |
From: Gideon Rosen (Metaphysical Dependence [2010], 10) | |
A reaction: My interest here is in whether we can say that we have found the 'essence' of an acid - so we want to know whether something 'deeper' explains the proton-donation. I suspect not. Being a proton donor happens to have a group of related consequences. |
