Regarding man's psycho-physical organization thus, we come to see in it a kind of polarity - a death-pole, as it were, represented by the nerves including their extension into the senses, and a life-pole, represented by the metabolic and muscular systems; and connected with them a pole of consciousness and one of unconsciousness - or as we can also say, of waking and sleeping consciousness. For the degree of consciousness on the side of the life-pole is not different from the state in which the entire human being dwells during sleep.
