What he wrote did not belong to his previous canon of dispassionate, academic essays on psychiatry. Nor was it a straightforward diary. It did not mention his wife, or his children, or his colleagues, nor for that matter did it use any psychiatric language at all. Instead, the book was a kind of phantasmagoric morality play, driven by Jung’s own wish not just to chart a course out of the mangrove swamp of his inner world but also to take some of its riches with him. It was this last part — the idea that a person might move beneficially between the poles of the rational and irrational, the light and the dark, the conscious and the unconscious — that provided the germ for his later work and for what analytical psychology would become.
