Letter 85 — On Some Vain Syllogisms (§5)

“They say, “The wise man is called unperturbed in the sense in which pomegranates are called mellow—not that there is no hardness at all in their seeds, but that the hardness is less than it was before.” That view is wrong; for I am not referring to the gradual weeding out of evils in a good man, but to the complete absence of evils; there should be in him no evils at all, not even any small ones. For if there are any, they will grow, and as they grow will hamper him. Just as a large and complete cataract wholly blinds the eyes, so a medium-sized cataract dulls their vision.”
