[280] The Sceptic, being a lover of his kind, desires to cure by speech, as best he can, the self-conceit and rashness ¹ of the Dogmatists. So, just as the physicians who cure bodily ailments have remedies which differ in strength, and apply the severe ones to those whose ailments are severe and the milder to those mildly affected,—so too the Sceptic propounds arguments which differ in strength,

[281] and employs those which are weighty and capable by their stringency of disposing of the Dogmatists' ailment, self-conceit, in cases where the mischief is due to a severe attack of rashness, while he employs the milder arguments in the case of those whose ailment of conceit is superficial and easy to cure, and whom it is possible to restore to health by milder methods of persuasion. Hence the adherent of Sceptic principles does not scruple to propound at one time arguments that are weighty in their persuasiveness, and at another time such as appear less impressive,—and he does so on purpose, as the latter are frequently sufficient to enable him to effect his object.
