February 21

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.

Wherefore ye should not be surprised that the Tablet of Wisdom is in conflict with the historical accounts. It behoveth one to reflect a while on the great diversity of opinion among the historians, and their contradictory accounts; for the historians of East and West are much at odds, and the Tablet of Wisdom was written in accordance with certain histories of the East.
