By a lie a man throws away and, as it were, annihilates his dignity as a man. A man who himself does not believe what he tells another . . . has even less worth than if he were a mere thing. . . . makes himself a mere deceptive appearance of man, not man himself.
Immanuel Kant, Doctrine of Virtue as translated by Mary J. Gregor (1964), p. 93.
