People who can say that have never understood a thing about life - they have never felt its breath, its heartbeat - however much they have seen or done. They look on it as a lump of raw material that needs to be processed by them. But life is never a material, a substance to be molded. If you want to know, life is the principle of self-renewal, it is constantly renewing and remaking and changing and transfiguring itself, it is infinitely beyond your or my obtuse theories about it.
