 Commitment to continual creation is thus an important constraint on Leibniz’s theory of causation. Ultimately, Leibniz adopts a form of concurrentism in which the natural change in the perceptual states of a created substance is due to the direct involvement of both the created substance and God. In other words, created substances possess genuine causal powers even while God’s own causal power is flexed everywhere in creation, including that of created substances and their states.
