What does it mean, insane? A legal definition. What do I mean? I feel it, see it, but what is it? It is something they do, something they are. It is their unconsciousness... Do they ignore parts of reality? Yes. But it is more. It is their plans... Their view; it is cosmic... They see through the here, the now, into the vast black deep beyond, the unchanging. And that is fatal to life. Because eventually there will be no life; there was once only the dust particles of space, the hot hydrogen gases, nothing more, and it will come again.
