" What do we know? What do we really know? He licks his dried cracked lips. We know this apodictic rock beneath our feet. That dogmatic sun above our heads. The world of dreams, the agony of love and the foreknowledge of death. That is all we know. And all we need to know? Challenge that statement. I challenge that statement. With what? I don't know. "

― Edward Abbey , The Monkey Wrench Gang (Monkey Wrench Gang, #1)
