The ontological theory about the two aristotelical intellects, created in the 13th century, finishes finally its itinerary with Ockham's epistemological theory. The realistic-propositionalist Ockham's epistemological theory reduces the intellect to a connotation: intellect denotes the soul, or better, the thinking subject whole and one; but connotes the man's cognitival function. The man is essentially free and directs his knowledge to its object, it is life and activity; but the denoted acognitival function is passive.
