- Let me pick up on Existence is Identity. I take it that this means if x
- exists then for some propery P, P(x) or more picturesquely, to be, is to
- be something.
-
- Suppose you encountered a phenomena that was totally alien to anything you
- had ever experienced, and suppose further more, that said phenomena
- ocurred only once (to you). How could you get a genre (genus) in which to
- fit this strange thing. If I understand Rand's epistomology every existant
- can be placed in a genus determined by its central characteristic, and
- then further differentiated from the genus and placed in a species
- (differentia). This would be the case if you had enough instances to
- compare and to contrast. But what do you do with once onlies? (sui generus).
-
- In a second order logic I don't believe that the formual
-
- (x)EP. P(x)
-
- is a semantic tautology. Can some expert out there comment on this.
