 Human beings have, so to speak, one leg in each realm: Through the body and its non-rational soul (the seat of appetitive and spirited desires and sense-perception) they belong to the sensible realm, through their higher soul (intellect) to the intelligible. Actually, the true human being is to be identified with the intellect and the intelligible Man. It follows from this that the task set for human beings is to free themselves from the sensible and live by the intelligible, which after all is their true or real nature.
