Conscience, the sense of right, the power of perceiving moral distinctions, the power of discerning between justice and injustice, excellence and baseness, is the highest faculty given us by God, the whole foundation of our responsibility, and our sole capacity for religion. ...God, in giving us conscience, has implanted a principle within us which forbids us to prostrate ourselves before mere power, or to offer praise where we do not discover worth.

Others are affected by what I am, and say, and do. So that a single act of mine may spread and spread in widening circles, through a nation or humanity. Through my vice I intensify the taint of vice throughout the universe. Through my misery I make multitudes sad.
