The world-soul or, in this case, the world-spirit is a projection of the unconscious, there being no method or apparatus which could provide an objective experience of this kind and thus furnish objective proof of the world’s animation.
Jung argues that the anima mundi/Weltseele is epistemologically a projection of the unconscious onto nature, not a demonstrable ontological entity, though this does not exhaust its psychological significance.
