I haven't a particle of confidence in a man who has no redeeming petty vices whatsoever. - Vicesimus Knox

You must master the vices. You know that if a thing is worth doing it's worth doing well. If, however, a thing is not worth doing then it's worth doing fabulously, amazingly, with grace, style and panache.”

L’hypocrisie est un hommage que le vice rend à la vertu.

The vices of which we are full we carefully hide from others, and we flatter ourselves with the notion that they are small and trivial; we sometimes even embrace them as virtues.
