Non-cooperation with evil is as much a duty as is cooperation with good. One may say that evil does not exist for subjective man at all, that there exist only different conceptions of good. Nobody ever does anything deliberately in the interests of evil, for the sake of evil. Everybody acts in the interests of good, as he understands it. But everybody understands it in a different way.
Consequently men drown, slay, and kill one another in the interests of good.
The quiet conscience is an invention of the devil. It is easier to denature plutonium than to denature the evil spirit of man. Sin is hoping for another life and eluding the implacable grandeur of this life. True human goodness, in all its purity and freedom, can come to the fore only when its recipient has no power. And in this respect mankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it.
