Resist no temptation: a guilty conscience is more honorable than regret

A guilty conscience needs to confess. A work of art is a confession.

Never do anything against conscience, even if the state demands it

The quiet conscience is an invention of the devil.

The evil that is in the world almost always comes of ignorance, and good intentions may do as much harm as malevolence if they lack understanding.

Man is the only creature that refuses to be what he is.
