he intends simply to present the Sceptical arguments
historically, and as they appear to him. He characterizes his
treatment of the subject as general rather than critical,
including a statement of the character of Scepticism, its idea,
its principles, its manner of reasoning, its criterion and aim,
and a presentation of the Tropes, or aspects of doubt, and the
Sceptical formulae and the distinction between Scepticism and
the related schools of philosophy.[1]

The result of all the gradual changes which the development of
thought had brought about in the outward relations of the
Sceptical School, was to increase the earnestness of the claim
of the Sceptics to be simply followers of Pyrrho, the great
founder of the movement. In discussing the names given to the
Sceptics, Sextus gives precedence very decidedly to the title
"Pyrrhonean," because Pyrrho appears the best representative of
Scepticism, and more prominent than all who before him occupied
themselves with it.[2]

It was a question much discussed among philosophers in ancient
times, whether Pyrrhonism should be considered a philosophical
sect or not. Thus we find that Hippobotus in his work entitled
[Greek: peri haireseôn], written shortly before our era, does
not include Pyrrhonism among the other sects.[3] Diogenes
himself, after some hesitation remarking that many do not
consider it a sect, finally decides to call it so.[4]
