ABSTRACT
Nature has always encompassed man in the fullness of his being. There are two aspects of man’s relation to nature revealed by scientific study that go far toward explaining the origin of these separatist doctrines. One of these aspects pertains to man’s physical make-up; the other to his mind. In these two aspects man must be recognized as the most surprising and marvelous of all natural productions. The similarity between man and inferior animals in so many physical particulars makes it possible for man to know many things about himself and to do to himself many advantageous things that he could never know and do but for his knowledge concerning these less complex creatures. It has long been recognized on the basis of their activities that many animals possess minds, and that these are similar in a considerable number of respects to human minds.
