But it is definite and not indefinite morality which differences man from the brute. Drummond, in his Ascent of Man, concedes that man passed through a period when he resembled the ape more than any known animal, but at the same time declares that no anthropoid ape could develop into a man. The brute can be defined in terms of man, but man cannot be defined in terms of the brute. It is significant that in insanity the higher endowments of man disappear in an order precisely the reverse of that in which, according to the development theory, they have been acquired. The highest part of man totters first. The last added is first to suffer. Man moreover can transmit his own acquisitions to his posterity, as the brute cannot. Weismann, Heredity, 2:69—“The evolution of music does not depend upon any increase of the musical faculty or any alteration in the inherent physical nature of man, but solely upon the power of transmitting the intellectual achievements of each generation to those which follow. This, more than anything, is the cause of the superiority of men over animals—this, and not merely human faculty, although it may be admitted that this latter is much higher than in animals.” To this utterance of Weismann we would add that human progress depends quite as much upon man’s power of reception as upon man’s power of transmission. Interpretation must equal expression; and, in this interpretation of the past, man has a guarantee of the future which the brute does not possess. (_c_) Psychology, however, comes in to help our interpretation of Scripture. The radical differences between man’s soul and the principle of intelligence in the lower animals, especially man’s possession of self-consciousness, general ideas, the moral sense, and the power of self-determination, show that that which chiefly constitutes him man could not have been derived, by any natural process of development, from the inferior creatures. We are compelled, then, to believe that God’s “breathing into man’s nostrils the breath of life” (Gen. 2:7), though it was a mediate creation as presupposing existing material in the shape of animal forms, was yet an immediate creation in the sense that only a divine reinforcement of the process of life turned the animal into man. In other words, man came not _from_ the brute, but _through_ the brute, and the same immanent God who had previously created the brute created also the man.
