[...] The more philosophers I read, the clearer it seemed that each of them could carry their views back to first principles which were incompatible with the first principles of their opponents, and that none of them ever got to that fabled place 'beyond hypotheses'. There seemed to be nothing like a neutral standpoint from which these alternative first principles could be evaluated. But if there were no such standpoint, then the whole idea of 'rational certainty', and the whole Socratic-Platonic idea of replacing passion by reason, seemed not to make much sense.
