Sextus Empiricus and Greek Scepticism | Page 4

of Empiricism and Scepticism would naturally support the view that Sextus was, at least during the earlier part of his life, a physician of that school, and yet it may be that he was not named Empiricus for that reason. There is one instance in ancient writings where Empiricus is known as a simple proper name.[1] It may have been a proper name in Sextus' case, or there are many other ways in which it could have originated, as those who have studied the origin of names will readily grant, perhaps indeed, from the title of the above-named work, [Greek: empeirika hupomnêmata.] The chief argument for this view of the case is that there were other leaders of the Sceptical School, for whom we can claim far greater influence as Empiricists than for Sextus, and for whom the surname Empiricus would have been more appropriate, if it was given in consequence of prominence in the Empirical School. Sextus is known to the world as a Sceptic, and not as a physician. He was classed in later times with Pyrrho, and his philosophical works survived, while his medical writings did not, but are chiefly known from his own mention of them. Moreover, the passage which we have quoted from the Hypotyposes is too strong to allow us easily to believe that Sextus remained all his life a member of the Empirical School. He could hardly have said, "Nor would it suit the Sceptic to take that sect upon himself," if he at the same time belonged to it. His other references to the Empirical School, of a more favorable character, can be easily explained on the ground of the long continued connection which had existed between the two schools. It is quite possible to suppose that Sextus was an Empiricist a part of his life, and afterwards found the Methodical School more to his liking, and such a change would not in any way have affected his stand as a physician.

In regard to the exact time when Sextus Empiricus lived, we gain very little knowledge from internal evidence, and outside sources of information are equally uncertain. Diogenes Laertius must have been a generation younger than Sextus, as he mentions the disciple of Sextus, Saturninus, as an Empirical physician.[1] The time of Diogenes is usually estimated as the first half of the third century A.D.,[2] therefore Sextus cannot be brought forward later than the beginning of the century. Sextus, however, directs his writings entirely against the Dogmatics, by whom he distinctly states that he means the Stoics,[3] and the influence of the Stoics began to decline in the beginning of the third century A.D. A fact often used as a help in fixing the date of Sextus is his mention of Basilides the Stoic,[4] [Greek: alla kai oi st?ikoi, ?s oi peri ton Basileidên]. This Basilides was supposed to be identical with one of the teachers of Marcus Aurelius.[5] This is accepted by Zeller in the second edition of his History of Philosophy, but not in the third for the reason that Sextus, in all the work from which this reference is taken, i.e. Math. VII.-XI., mentions no one besides Aenesidemus, who lived later than the middle of the last century B.C.[6] The Basilides referred to by Sextus may be one mentioned in a list of twenty Stoics, in a fragment of Diogenes Laertius, recently published in Berlin by Val Rose.[7] Too much importance has, however, been given to the relation of the mention of Basilides the Stoic to the question of the date of Sextus. Even if the Basilides referred to by Sextus is granted to have been the teacher of Marcus Aurelius, it only serves to show that Sextus lived either at the same time with Marcus Aurelius or after him, which is a conclusion that we must in any case reach for other reasons.

The fact that has caused the greatest uncertainty in regard to the date of Sextus is that Claudius Galen in his works mentions several Sceptics who were also physicians of the Empirical School,[1] and often speaks of Herodotus, supposed to be identical with the teacher of Sextus given by Diogenes Laertius,[2] but makes no reference whatever to Sextus. As Galen's time passes the limit of the second century A.D., we must either infer that Sextus was not the well-known physician that he was stated to be by Pseudo-Galen, and consequently not known to Galen, or that Galen wrote before Sextus became prominent as a Sceptic. This silence on the part of Galen in regard to Sextus increases the doubt, caused
