Note 156 — BOOK VI SIMON MAGUS, VALENTINUS, AND THEIR FOLLOWERS
Francis Legge translation
What follows is from Plato’s Second Epistle, which is thought to have been written after Plato’s return from his third voyage to Syracuse, and is perhaps rather less suspect than the other Platonic epistles. Yet the chances of interpolation are so great that no stress can be laid on the genuineness of any particular passage.
