 One should also emphasize that his neo-Pyrrhonism has to be sharply distinguished from Cartesian skepticism. Porchat makes it clear that neo-Pyrrhonian aporiai are a different sort of argument from Cartesian doubts. In particular, neo-Pyrrhonism is not committed to mentalism (the doctrine that one can conceive the mind, and its representations, as independent from the body) and does not it invite any sort of solipsism. Thus, most of the criticisms leveled against Cartesian skepticism do not apply to neo-Pyrrhonism.
