A quote
Conversely, however, in order that you may know that there is an idea of good conduct present subconsciously in souls which have been led even into the most depraved ways, and that men are not ignorant of what evil is but indifferent—I say that all men hide their sins, and, even though the issue be successful, enjoy the results while concealing the sins themselves. A good conscience, however, wishes to come forth and be seen of men; wickedness fears the very shadows.
