“Ignorance of the law of irreducibility was no excuse. I could no longer excuse myself with the claim that I didn't know the law -- for knowledge of self and of the world is the law that, even though unattainable, cannot be broken, and no one can excuse himself by saying that he doesn't know it. . . . The renewed originality of the sin is this: I have to carry out my unknowing, I shall be sinning originally against life.”
