Man is in the highest degree of materiality,

Man is in the highest degree of materiality, and at the beginning of spirituality; that is to say, he is the end of imperfection and the beginning of perfection. He is at the last degree of darkness, and at the beginning of light; that is why it has been said that the condition of man is the end of the night and the beginning of day, meaning that he is the sum of all the degrees of imperfection, and that he possesses the degrees of perfection. He has the animal side as well as the angelic side; and the aim of an educator is to so train human souls, that their angelic aspect may overcome their animal side. Then, if the divine power in man which is his essential perfection, overcomes the satanic power, which is absolute imperfection, he becomes the most excellent among the creatures; but if the satanic power overcomes the divine power, he becomes the lowest of the creatures. That is why he is the end of imperfection and the beginning of perfection. Not in any other of the species in the world of existence is there such a difference, contrast, contradiction, and opposition, as in the species of man. Thus the reflection of the Divine Light was in man, as in Christ, and see how loved and honored He is! At the same time we see man worshipping a stone, a clod of earth, or a tree: how vile he is, in that his object of worship should be the lowest existence—that is a stone, or clay, without spirit; a mountain, a forest, or a tree. What shame is greater for man than to worship the lowest existence? In the same way, knowledge is a quality of man, and so is ignorance; truthfulness is a quality of man, so is falsehood; trustworthiness and treachery, justice and injustice, are qualities of man, and so forth. Briefly, all the perfections and virtues, and all the vices, are qualities of man.
