Jung's great step forward and the justification for the term 'synthesis' is precisely his abandonment of the unambiguous causal thinking of the old psychologyI-namely,

his recognition that the spirit must not be viewed as epiphenomenon, as 'sublimation', but as a principle sui genens, as a formative and therefore as t}le highest principle through which 'Gestalt', organized structure, is psychologically and perhaps also physically possible.! For conclusions _that thinkers such as Whitehead and Eddington have drawn from physics itself point actually to primary, formative, spiritual forces, which could be, and probably already have been, characterized as 'mystic'.
