Voluntarism: A philosophical view that makes a choice of the will to be an essential aspect of the understanding of some phenomena. Thus voluntarism with respect to beliefs is the claim that beliefs are chosen or willed. Theological voluntarism holds that God’s will is in some way superior to or independent of his intellect. For example, a theological voluntarist might say that what is good is good because God wills it, and God’s understanding of goodness is thus dependent on his willing. A weak sense of voluntarism holds that human will is not determined by the intellect; thus a person does not necessarily choose what the understanding sees as the best option.1
