| 16795 | Same person, man or substance are different identities, belonging to different ideas [Locke] |
| Full Idea: It is one thing to be the same substance, another the same man, and a third the same person, if Person, Man and Substance are three names standing for three different ideas; for such as is the idea belonging to the name, such must be the identity. | |
| From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 2.27.07) | |
| A reaction: It might be better to say that two things can only be 'the same' in some respect. You can say 'in some respects they are the same', without citing the respects. |
| 12504 | Two things can't occupy one place and time, which leads us to the idea of self-identity [Locke] |
| Full Idea: We don't conceive it possible that two things of the same kind should exist in the same place and time...When, therefore, we demand whether any thing be the same or no, it refers to something that existed at a time and place, and was the same with itself. | |
| From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 2.27.01) | |
| A reaction: I find the notion of 'self-identity' puzzling. I've always taken it to be a logicians' idea, but Locke seems to arrive at it by looking for whatever is identical with some original object, and the floating relation having to hook back onto itself. |
