When we view the world of creation, we find that all living things may be classified under two aspects of existence. First, they possess bodies composed of material substance common to all—whether vegetable, animal or human. This is their point of agreement or, as it is philosophically termed, their point of contact. Second, they vary and differ from each other in degree and function—that is to say, in their respective kingdoms. This is their point of distinction and differentiation. For instance, the vegetable and animal are alike in the fact that their bodies are composed of the same material elements but widely different in their kingdoms and powers. Man is like the animal in physical structure but otherwise immeasurably separated and superior.
