Famous quotes containing the word state:
“Scepticism is an ability, or mental attitude, which opposes appearances to judgments 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.”
—Sextus Empiricus (2nd or 3rd cen., A.d.)
