In conjunction with the PC 548 passage above, the view seems to be that our volitions are more than mere occasions for Gods causal activity. In other words, when I will to move my hand, there seems to be more going on than God directly and solely causing my hand to move. Rather, we bring about the movements ourselves, because not only do we will the movements, but the effects follow from these volitions. What means Cause as distinguishd from Occasion?
