Note 4 — BOOK I[1] THE PHILOSOPHERS

There seems no reason for numbering Pyrrho of Elis among the members of the Academy, Old or New. Diogenes Laertius, from whose account of his doctrines Hippolytus seems to have derived the dogma of incomprehensibility which he here attributes to Pyrrho, makes him the founder of the Sceptics. He was a contemporary of Alexander the Great, and probably died before Arcesilaus founded the New Academy in 280 B.C.
