“The right will is, therefore, well-directed love, and the wrong will is ill-directed love. Love, then, yearning to have what is loved, is desire; and having and enjoying it, is joy; fleeing what is opposed to it, is fear; and feeling what is opposed to it, when it has befallen it, it is sadness. Now these motions are evil if the love is evil; good if the love is good.” —Augustine, The City of God
