Abstract

In reaffirming the intimate link between mind and life, John Duns Scotus is faithful to Augustine. His conception of the rational soul, however, differs from Augustine's trinitarian image, since he stresses the difference between intellect and memory on the one hand, and will on the other hand. He also departs from Augustine by attributing, in his theory of intelligible species, a real, if partial, causal role to the external object in their generation. The principle that there cannot be more reality in an effect than in its cause is true only of the total cause, and not of a partial cause, because an inferior partial cause can concur with a superior partial cause, such as the intellect, to produce a common effect, the perfection of which surpasses its own.
