Man demands truth and fulfills this demand in moral intercourse with other men; this is the basis of all social life. One anticipates the unpleasant consequences of reciprocal lying. From this there arises the duty of truth. We permit epic poets to lie because we expect no detrimental consequences in this case. Thus the lie is permitted where it is considered something pleasant. Assuming that it does no harm, the lie is beautiful and charming.
