" The word conscience covers as a matter of fact several different feelings; the simplest of these is the fear of being found out. You, reader, have, I am sure, lived a completely blameless life, but if you will ask some one who has at some time acted in a manner for which he would be punished if it became known, you will find that when discovery seemed imminent, the person in question repented of his crime. "

― Bertrand Russell , The Conquest of Happiness
