 Thus he has proved what he calls the “triple primacy”: there is a being that is first in efficient causality, in final causality, and in pre-eminence. Scotus next proves that the three primacies are coextensive: that is, any being that is first in one of these three ways will also be first in the other two ways. Scotus then argues that a being enjoying the triple primacy is endowed with intellect and will, and that any such being is infinite. Finally, he argues that there can be only one such being.
