As to what thou didst ask regarding the history of the philosophers: history, prior to Alexander of Greece, is extremely confused, for it is a fact that only after Alexander did history become an orderly and systematized discipline. One cannot, for this reason, rely upon traditions and reported historical events that have come down from before the days of Alexander. This is a matter thoroughly established, in the view of all authoritative historians. How many a historical account was taken as fact in the eighteenth century, yet the opposite was proved true in the nineteenth. No reliance, then, can be placed upon the traditions and reports of historians which antedate Alexander, not even with regard to ascertaining the lifetimes of leading individuals.
