Chapter VI The Origin of Scepticism
Scepticism arose in the beginning from the hope of attaining ἀταραξία; for men of the greatest talent were perplexed by the contradiction of things, and being at a loss what to believe, began to question what things are true, and what false, hoping to attain ἀταραξία as a result of the decision. The fundamental principle of the Sceptical system is especially this, namely, to oppose every argument by one of equal weight, for it seems to us that in this way we finally reach the position where we have no dogmas.
