God’s omniscient direction of the world should lead us to observe measure, since he ordered all things in measure, number, and weight… weight is ascribed to the Holy Spirit.
Von Franz recovers the alchemical-Scholastic tradition in which weight is not mere physical mass but the pneumatic principle of divine attraction, attributed specifically to the Holy Spirit and grounding a triadic cosmological psychology.
