" Every system resists dissolution and reacts to danger with pain, just as it reacts to stimulation and libido enrichment with pleasure. Since the ego is the center of the conscious system, we identify ourselves primarily with the pleasure-pain reactions of this system as though they were our own. But in reality the source of the ego’s pleasure-pain experience is by no means only the conscious system. "

― Erich Neumann , The Origins and History of Consciousness
