Miguel de Unamuno on Guilt and ConscienceTragic Sense of Life, trans. J.E. Crawford Flitch (Dover: 1954; orig. 1921), p. 291.
The fact that society is guilty aggravates the guilt of each one, and he is most guilty who most is sensible of the guilt. Christ, the innocent, since he best knew the intensity of guilt, was in a certain sense the most guilty. In him the culpability, together with the divinity, of humanity arrived at the consciousness of itself. Many are wont to be amused when they read how, because of the most trifling faults, faults at which a man of the world would merely smile, the greatest saints counted themselves the greatest sinners. But the intensity of the fault is not measured by the external act, but by the consciousness of it, and an act for which the conscience of one man suffers acutely makes scarcely any impression on the conscience of another. And in a saint, conscience may be developed so fully and to such a degree of sensitiveness that the slightest sin may cause him more remorse than his crime causes the greatest criminal. And sin rests upon our consciousness of it, it is in him who judges and in so far as he judges. When a man commits a vicious act believing in good faith that he is doing a virtuous action, we cannot hold him morally guilty, while on the other hand that man is guilty who commits an act which he believes to be wrong, even though in itself the act is indifferent or perhaps beneficent. The act passes away, the intention remans, and the evil of the act is that it corrupts the intention, that in knowingly doing wrong a man is predisposed to go on doing it, that it blurs the conscience. And doing evil is not the same being evil. Evil blurs the conscience, and not only the moral conscience, but the general, psychical consciousness. And everything that exalts and expands conscious is good, while that which depresses and diminishes it is evil.
