Abstract

I try to show that Descartes criterion of truth is neither viciously circular nor does it, alternatively, commit him to an infinite hierarchy of criteria. As a result, he is able to resolve the age-old "problem of the criterion" as it was known both to the Greek sceptics and Montaigne. Beyssade's interpretation of Descartes' criterion, on the other hand, is inconsistent with its being a criterion at all and has disastrous consequences for the rest of Descartes' philosophy
