"Sooner or later nuclear physics and the psychology of the unconscious will draw closely together as both of them independently of one another and from opposite directions, push forward into transcendental territory. …Psyche cannot be totally different from matter for how otherwise could it move matter? And matter cannot be alien to psyche, for how else could matter produce psyche? Psyche and matter exist in the same world, and each partakes of the other, otherwise any reciprocal action would be impossible. If research could only advance far enough, therefore, we should arrive at an ultimate agreement between physical and psychological concepts. Our present attempts may be bold, but I believe they are on the right lines."
