ABSTRACT
The modern psychological description of man as a totality had its precursors in the many biographical accounts of unusual people such as somnambulist and the like at the beginning of the nineteenth century. The question discussed here is a weighty one for the future. Science has only just begun to take a serious interest in the human psyche and, more particularly, in the unconscious. The wide realm of psychic phenomena also includes parapsychology, which is opening undreamed of vistas before our eyes. It is time humanity took cognizance of the nature of the psyche, for it is becoming more and clearer that the greatest danger which threatens man comes from his own psyche and hence from that part of the empirical world we know the least about. Psychology needs a tremendous widening of its horizon. It is a milestone on the long road to knowledge of the psychic nature of man.
