Boghossian’s discrimination argument aims to show that content externalism undermines the privileged access thesis. Simon Dierig has recently proposed a new objection to Boghossian’s argument according to which having a “twater thought” is not an alternative, and a fortiori not a relevant alternative, to possessing a “water thought”. Dierig also considers, and criticizes, a modified version of the discrimination argument which would be immune to his objection. I shall argue, first, that he fails to advance a successful objection to the (...) original version of the argument; and, second, that his criticism of the modified version is misconceived. (shrink)
