When we examine all things with the eye of discernment, we observe that they are generally confined to three categories: mineral, vegetable, and animal. Thus there are three classes of beings and each class has its associated species. Man is the most distinguished species in that he combines the perfections of all three classes—that is, he possesses a material body, the power of growth, and the power of sensation. Beyond the mineral, vegetable, and animal perfections, however, he also possesses a special perfection of which other created things are bereft, namely, the perfections of the mind. Thus man is the noblest of all existing things.
Man is in the ultimate degree of materiality and the beginning of spirituality; that is, he is at the end of imperfection and the beginning of perfection. He is at the furthermost degree of darkness and the beginning of the light. That is why the station of man is said to be the end of night and the beginning of day, meaning that he encompasses all the degrees of imperfection and that he potentially possesses all the degrees of perfection. He has both an animal side and an angelic side, and the role of the educator is to so train human souls that the angelic side may overcome the animal. Thus, should the divine powers, which are identical with perfection, overcome in man the satanic powers, which are absolute imperfection, he becomes the noblest of all creatures, but should the converse take place, he becomes the vilest of all beings. That is why he is the end of imperfection and the beginning of perfection.
