Herbert Spencer and à priori Truths

Superfi cially and Deeply Contingent A Priori Truths

In this paper, I review some standard approaches to the cases of contingent a priori truths that emerge from Kripke’s (1980) discussion of proper names and Kaplan’s (1989) theory of indexicals.

I shall raise doubts about Evans’ strategy in general, and also about the roots and meaningfulness ...

It is known in general only for the cases i = 0, 1, 2d − 1, 2d where d = dimX. The pur...
