Is the T-scheme true?

Resumen

The T-scheme is:  'P' is true iff P.  In this note I ask the question whether the T-scheme is true.  Strictly speaking, the T-scheme itself is not true, though specific instances of the T-scheme are true.  In particular, it is argued that the T-scheme is analytically true in both the epistemic and the metaphysical senses of analyticity.
