The Stoics, therefore, appear to me to be mistaken in refusing to admit that a man who is advancing in wisdom has any wisdom at all, and in affirming that he alone has it who has become altogether perfect in wisdom. They do not, indeed, deny that he has made progress, but they say that he is in no degree entitled to be called wise, unless, by emerging, so to speak, from the depths, he suddenly springs forth into the free air of wisdom. For, as it matters not when a man is drowning whether the depth of water above him be many stadia or only the breadth of a hand or finger, so they say in regard to the progress of those who are advancing towards wisdom, that they are like men rising from the bottom of a whirlpool towards the air, but that unless they by their progress, so escape as to emerge wholly from folly as from an overwhelming flood, they have not virtue and are not wise; but that, when they have so escaped, they immediately have wisdom in perfection, and not a vestige of folly whence any sin could be originated remains.
