Michael Williams believes that scepticism about the externalworld seems compelling only because the considerations that underpin it are thoughtto be ``mere platitudes'' about e.g., the nature and source of human knowledge, and hence,that if it shown through a ``theoretical diagnosis'' that it does not rest upon suchplatitudes, but contentious theoretical considerations that we are no means bound toaccept, we can simply dismiss the absurd sceptical conclusion. Williams argues thatscepticism does presuppose two extremely contentious doctrines, however, he admits thatif these doctrines (...) are themselves motivated by ``platitudes'' then scepticism follows. Iaddress Williams's arguments for thinking scepticism must presuppose these doctrines,and argue that he overlooks a way that they can be seen as motivated by mere platitudes.Thus, I conclude that William's novel rejection of scepticism fails.

I argue that Wittgenstein's rejection of scepticism in On Certainty rests on the view that epistemic concepts such as‘doubt,‘knowledge’,‘justification’and so on, cannot be intelligibly applied to the common sense propositions that traditional sceptical arguments appear to undermine. I detect two strands in On Certainty in support of this view. I attempt to show that neither of these strands adequately establishes the thesis, and that they point to a tension in Wittgenstein's treatment of scepticism. I argue that the first strand is (...) dogmatic, but accords with the constraints of Wittgenstein's method, while the second strand avoids the dogmatism of the first at the cost of violating these constraints.
