 Hume follows his sentimentalist predecessor, Francis Hutcheson (1694–1746), in building his moral theory around the idea of a spectator who approves or disapproves of people’s character traits and motives. The sentiments of approval and disapproval are the source of our moral ideas of goodness and badness. To evaluate a character trait as morally good is to evaluate it as virtuous; to evaluate it as morally bad is to evaluate it as vicious.
