 A judging God who has plans and acts purposively is a God to be obeyed and placated. Opportunistic preachers are then able to play on our hopes and fears in the face of such a God. They prescribe ways of acting that are calculated to avoid being punished by that God and earn his rewards. But, Spinoza insists, to see God or Nature as acting for the sake of ends—to find purpose in Nature—is to misconstrue Nature and “turn it upside down” by putting the effect (the end result) before the true cause.
