Diogenes Laertius says that "once the sage has become wise, they will no longer fall back into ignorance."
Agreed that is a parallel, but I would also say that that one probably calls for some explanations as it applies to humans, because in the absence of fate and given the presence of the swerve / free will, you would think that it would be hard to guarantee that every decision is wise.
Possibly means something about the wise man won't "intentionally" fall back into error? But even then, this statement has kind of a Stoic/Platonic ring to it, and I would probably add it into a list of statements by Diogenes Laertius that need to be scrutinized before accepting at the face value at which it's usually translated(?)
