St. Isaac the Syrian

If you cannot be merciful, at least speak as though you are a sinner. If you are not a peacemaker, at least do not be a troublemaker. If you cannot be assiduous, at least in your thought be like a sluggard. If you are not victorious, do not exalt yourself over the vanquished. If you cannot close the mouth of a man who disparages his companion, at least refrain from joining him in this.

The chaplain had sinned, and it was good. Common sense told him that telling lies and defecting from duty were sins. On the other hand, everyone knew that sin was evil, and that no good could come from evil. But he did feel good; he felt positively marvelous. Consequently, it followed logically that telling lies and defecting from duty could not be sins. The chaplain had mastered, in a moment of divine intuition, the handy technique of protective rationalization, and he was exhilarated by his discovery. It was miraculous. It was almost no trick at all, he saw, to turn vice into virtue and slander into truth, impotence into abstinence, arrogance into humility, plunder into philanthropy, thievery into honor, blasphemy into wisdom, brutality into patriotism, and sadism into justice. Anybody could do it; it required no brains at all.

A Portrait of the Artist as a Young Man

A cold lucid indifference reigned in his soul. At his first violent sin he had felt a wave of vitality pass out of him and had feared to find his body or his soul maimed by the excess. Instead the vital waved had carried him on its bosom out of himself and back again when it receded; and no part of body or soul had been maimed but a dark peace had been established between them. The chaos in which his ardour extinguished itself was a cold indifferent knowledge of himself.
