Note 27 — ON ABSTINENCE FROM ANIMAL FOOD. BOOK THE FIRST.
Thomas Taylor translation
The multitude are ignorant that they are ignorant with respect to objects of all others the most splendid and real; but the Coryphæan philosopher is ignorant that he is ignorant with respect to objects most unsubstantial and obscure. The former ignorance is the consequence of a defect, but the latter of a transcendency of gnostic energy. What Porphyry here says of the Coryphæan philosopher, is derived from the Theætetus of Plato.
