Skepticism relieved two terrible diseases that afflicted mankind: anxiety and dogmatism.
Sextus EmpiricusDemocritus sometimes does away with what appears to the senses, and says that none of these appears according to truth but only according to opinion: the truth in real things is that there are atoms and void. 'By convention sweet', he says, 'by convention bitter, by convention hot, by convention cold, by convention colour: but in reality atoms and void.'
Sextus EmpiricusScepticism 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.
