From what has just been said man's pre-eminence cannot consist in any anatomical characteristic, even of the brain--much less of thumb, forefinger, hand, or foot. But man's mental and moral characteristics (even though germs of these may be present in the animal), whether differing in degree or kind from theirs, raise his life to a totally different plane. He lives in an environment of which the lower animal is as unconscious and ignorant as we of a fourth dimension of space. He has the knowledge of abstract truth and goodness, of certain standards outside of mere appetite and desire, and feels and acknowledges, however dimly, the requirement and the ability to conform his life to these standards. He alone can say "I ought," and answer "I can and will." And hence man alone actually lives in an environment of the laws of reason, responsibility, and personality. Whatever germs of these higher powers the animal possesses are means to material ends, to the physical life of the animal. In man the long and slow evolution has ended in revolution, the material and physical have been dethroned, and truth and goodness reign supreme as ends in themselves. But, you may object, this definition of man may be true ideally, certainly it is not true actually. Where are the high ideals of truth and goodness in the savage? and are these the supreme ends of even the average American of to-day? But allowing all weight to this objection, does it not remain true that a being who never says "I ought," who acknowledges and manifests no responsibility, to whom goodness does not appeal, and in whom these feelings cannot be awakened, is either not yet or no longer man? But far more than this, if the character of the individual is to be judged by his tendency more than his present condition, by the way in which he is going more than his momentary position, is not the race to be judged and defined by a tendency, gradually though very slowly becoming realized, and a goal, toward which it looks and which it is surely attaining, rather than by its present realization? As we rise higher in the animal kingdom the characteristics of the successive higher groups are more and more slow of attainment and difficult of realization, just because of their grander possibilities. And this is true and important above all in the case of man. His possibilities are beyond our powers of conception, for, if you will, man is yet only larval man.
