Identity/I/Anscombe: difference: Descartes doubts the identity with Descartes/with Descartes himself. It is something different for Descartes to doubt the identity of Descartes with Descartes, than the identity of his own with Descartes -> Kripke/Frank - Anscombe: then it is possible that one does not know that he speaks of himself. -> E.g. the tallest man.
Identity/I/Chisholm: results from direct attribution; if x directly assigns something to y, then x is identical with y. - Everyone has privileged access - but we do not explain it by the use of I, but vice versa: the use of the pronoun by direct attribution. - primary use of I am: someone says of himself that he himself ... - pronoun: does not express any part of the content.
