THOSE whom we call the Pyrronian philosophers are designated by the Greek name skeptikoi/, or sceptics, which means about the same as inquirers and investigators. For they decide nothing and determine nothing, but are always engaged in inquiring and considering what there is in all nature concerning which it is possible to decide and determine. And moreover they believe that they do not see or hear anything clearly, but that they undergo and experience something like seeing and hearing; but they are in doubt as to the nature and character of those very things which cause them those experiences, and they deliberate about them: and they declare that in everything assurance and absolute truth seem so beyond our grasp, owing to the mingling and confusing of the indications of truth and falsehood, that any man who is not rash and precipitate in his judgment ought to use the language which they say was used by Pyrro, the founder of that philosophy: Does not this matter stand so, rather than so, or is it neither? For they deny that proofs of anything and its real qualities can be known and understood, and they try in many ways to point this out and demonstrate it. On this subject Favorinus too with great keenness and subtlety has composed ten books, which he entitled Purrwnei=oi Tro/poi, or The Pyrronian Principles. p. 88, Marres. Apparently a discussion of the arguments by which the Pyrronian philosophers supported their beliefs.
