We do not sustain ourselves in virtue by our own strength, but by the balancing of two opposed vices, just as we remain upright amidst two contrary gales.

Context

“and vices present themselves in a crowd towards the infinitely great, so that we lose ourselves in them, and no longer see virtues. We find fault with perfection itself. 358 Man is neither angel nor brute, and the unfortunate thing is that he who would act the angel acts the brute. [134] 359 We do not sustain ourselves in virtue by our own strength, but by the balancing of two opposed vices, just as we remain upright amidst two contrary gales. Remove one of the vices, and we fall into the other. 360 What the Stoics propose is so difficult and foolish! The Stoics lay down that all those who are not at the high degree of wisdom are equally foolish and vicious, as those who are two inches under water.” source
