C, I was sure that you were on the other side of this in the olden days of Orcutt the master spy, but, in any case, you now seem to be on the wrong side. Usual argument: knowledge is intensional, so works only with intensional identities, Freya=Venus is only extensional if not known, hence replacement does not go through. As soon as the knower comes to know the identity and make use of it, then he knows about Freya. But not until. |
