Of all the unexpected qualities of an unexpected universe, the sheer organizing power of animal and plant metabolism is one of the most remarkable. . . . Where it reaches its highest development, in the human mind, we forget it completely. . . . So important does nature regard this unseen combustion . . . that a starving man's brain will be protected to the last while his body is steadily consumed.

Many of us who walk to and fro upon our usual tasks are prisoners drawing mental maps of escape.

When the human mind exists in the light of reason and no more than reason, we may say with absolute certainty that Man and all that made him will be in that instant gone.

Tomorrow lurks in us, the latency to be all that was not achieved before.

When man becomes greater than nature, nature, which gave him birth, will respond.

Once in a lifetime, perhaps, one escapes the actual confines of the flesh. Once in a lifetime, if one is lucky, one so merges with sunlight and air and running water that whole eons, the eons that mountains and deserts know, might pass in a single afternoon without discomfort.

Man would not be man if his dreams did not exceed his grasp... If I remember the sunflower forest it is because from its hidden reaches man arose. The green world is his sacred center. In moments of sanity he must still seek refuge there.
