Ancient & Medieval Philosophy -- David L. Rouse
- Sextus Empircus defines skepticism as follows.
“Scepticism is an ability, or mental attitude, which opposes appearances to judgements in any way whatsoever, with the result that, owing to the equipollence of the objects and reasons thus opposed, we are brought firstly to a state of mental suspense and next to a state of "unperturbedness" or quietude.”
