As physics is a mental reconstruction of material processes, perhaps a physical reconstruction of psychic… — Marie-Louise von Franz

The mathematical forms of order which the mind of a physicist manipulates coincides "miraculously" with experimental measurements.

Number, as it were, lies behind the psychic realm as a dynamic ordering principle, the primal element of which Jung called spirit. As an archetype, number becomes not only a psychic factor, but more generally, a world-structuring factor. In other words, numbers point to a background reality in which psyche and matter are no longer distinguishable.

…Jung even asserted that he would have no objection to regarding the psyche as a quality of matter and matter as a concrete aspect of the psyche, provided that the psyche was understood to be the collective unconscious.
