" The unexpected parallelisms of ideas in psychology and physics suggest, as Jung pointed out, a possible ultimate one-ness of both fields of reality that physics and psychology study-i.e., a psychophysical one-ness of both fields of reality that physics and psychology study-i.e., a psychophysical one-ness of all life phenomena. Jung was even convinced that what he calls the unconscious somehow links up with the structure of inorganic matter-a link to which the problem of so-called "psychosomatic" illness seems to point. The concept of a unitarian idea of reality (which has been followed up by Pauli and Erich Nuemann) was called by Jung the unus mundus (the one world, within which matter and psyche are not yet discriminated or separately actualized). He paved the way toward such a unitarian point of view by pointing out that an archetype shows a "psychoid" (i.e., not purely psychic but almost material) aspect when it appears within a synchronistic event-for such an event is in effect a meaningful arrangement of inner psychic and outer facts.
