AS MENTIONED BEFORE, the nature of the stress of wakefulness is not understood by biologists, neurologists, psychologists and psychiatrists. Neither is the riddle of the resolution of stress during sleep sufficiently understood. Science does not recognize the transcendental functions of the CNS, which are the basis of experience, nor does it recognize the contrast between the intentional principles of Eros and Thanatos, which becomes more manifest the higher one rises on the communication ladder, from the morphogenetic icon-stage to the cellular style of communication.
