The vices are very justly man's executioners. - Vicesimus Knox

No vice exists which does not pretend to be more or less like some virtue, and which does not take advantage of this assumed resemblance.

O philosophy, life’s guide! O searcher-out of virtue and expeller of vices! What could we and every age of men have been without thee?

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.
