| 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. |
