And this makes the great difficulty in assigning man his proper place in our systems of classification. Our zoölogical classifications depend upon anatomical characteristics; and anatomically man belongs among the order primates. But mental and moral values cannot be expressed in terms of anatomy, any more than we can speak of an idea of so many horse-power, and hence worth three or four ancestral dollars. Hence, while from the zoölogical standpoint man is a primate, and while he is very probably descended from one of these, he has gradually risen above them mentally and spiritually, so that he stands as far above them as they above the lowest worm. And this leads us to the consideration of man, not merely as a mammal, but as "Anthropos," Homo sapiens, although he often degenerates into "Simia destructor."
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.
We have followed the sequence of functions to its culmination in a mind completely dominated by righteousness and unselfishness, however far above our present attainments this goal may be. We have found that all attempts to reverse this sequence end in death or degeneration. Failure to advance, especially in higher forms, results in extinction or retrogression. We cannot stand still. Each higher step is longer and more important than any preceding; each last step is essential to life. Righteousness in the will is the last step essential to man's progress. And if a sound mind in a sound body is important or necessary, a sound will, resolutely set on right, is absolutely essential. Failure to attain this is ruin.
And man can to a great extent place himself so that his surroundings shall aid him to take this last, essential, upward step. He does this by the choice of his associates. If he associates himself with men who are tending upward, he will rise ever higher. If he choose the opposite kind of associates he must sink into ever deeper degradation; he has thereby chosen death. For his associates, once chosen, make him like themselves. And thus natural selection makes for the survival of those men who resolutely choose life. And thoughtless or careless failure to choose is ruin. The man has preferred degradation; it is only right that he should have it to satiety.
But man is not, and never can be, pure spirit. He may "let the ape and tiger die," but he must always retain the animal with its natural appetites. Moreover, his higher mental capacities increase their power. Memory recalls past gratifications as it never does to the animal; imagination paints before him vivid pictures of similar future enjoyments, and mental keenness and strength of will tell him that they can all be his. But if he yields himself a slave to these appetites, if he seeks to be an animal rather than a spiritual being, he becomes not an animal but a brute; and the only genuine brute is a degenerate man. And thus after conquering the world man's very structure compels him to join battle with himself. For here, as everywhere else, to attempt to go backward to a plane of life once passed is to surely degenerate. The time when the prize of pre-eminence could be won by mere physical superiority was passed before man had a history. Physical superiority must be maintained, and every advance in art and science, considered here as ministering to man's physical comfort, is advantageous just so far as these allow man freedom and aid to pursue the mental and moral line which is the only true path left open to him. But when even these are allowed to minister only to the animal, or to tempt to luxurious ease and indifference to any higher aims, in a word, in so far as they fail to minister to mental and moral advancement, they are in great danger of becoming, if they have not already become, a curse rather than a blessing. And we all know that this has been proven over and over again in human history. Families, cities, and nations rot, mainly because they cannot resist the seductions of an overwhelming material prosperity. A man says to his soul, "Take thine ease, eat, drink and be merry," and to that man scripture and science say, with equal emphasis, "Thou fool!"
Every upward step in attainment of the comforts of life, of art and science, brings man into new fields not of careless enjoyment but of struggle. They swarm with new enemies and temptations before unknown. The new attainments are not unalloyed blessings, they are merely opportunities for victory or defeat. The uncertain battle is only shifted to a little higher plane. Man has increased the forces at his command only to meet stronger opposing hosts. And retreat is impossible. Man remains a spiritual being only on condition that he resolutely and vigilantly purposes to be so. To lag behind in this spiritual path is death.
And the epitaph of nations and individuals is the record of their defeat in this struggle to be masters and not slaves of their material and intellectual attainments. Greece, the most intellectual of all nations of all times, died in mental senility of moral paralysis. Of Socrates's and Plato's "following after truth" nothing remained but the gossipy curiosity of a second childhood, living only to tell or to hear some new thing. And the schools of philosophy were closed because they had nothing to tell which was worth the knowing or hearing. All the wealth of the world was poured into Rome, the home of Stoic philosophy, and it was smothered, and died in rottenness under its material prosperity.
A family, race, or nation starts out fresh in its youthful physical and mental vigor and strict obedience to moral law and in its faith in God. For these reasons it survives in the struggle for existence. It grows in extent and power, in intelligence and wealth. But with this increase in wealth and power comes a deadening of the mind to the claims of moral law, and an idolatrous worship of material prosperity. The new generation looks upon the stern morality and industry and self-control of its ancestors as straight-laced and narrow. Morality may not be unfashionable, but any stern rebuke of immorality is not conventional. Strong moral earnestness and whole-souled loyalty to truth are not in good form. Wealth and social position become the chief ends of men's efforts, and, to buy these, unselfishness and truth and self-respect are bartered away. Luxury, enervation, and effeminacy are rife, and snobbery follows close behind them. The ancestral vigor, the insight to recognize great moral principles, and the power to gladly hazard all in their defence have disappeared in a mist of indifference, which beclouds the eyes and benumbs all the powers. The race of giants is dwindling into dwarfs. They say, when the time comes, we will rouse ourselves and be like our fathers. And the crisis comes, but they are not equal to it. The nation has long enough cumbered the ground, it has already died by suicide and must now give place to a race and civilization which has some aim in, and hence right to, existence, and which is of some use to itself and others. If we would learn by observation, and not by sad experience, we must remember that man is above all, and must be a religious being conforming to the personality of the God manifested in his environment.
Can you find anywhere a more profound or scientific philosophy of history than that of Paul in the first chapter of Romans? "For the invisible things of him since the creation of the world are clearly seen, being perceived through the things that are made, even his everlasting power and divinity; so that they are without excuse: because that, knowing God, they glorified him not as God, neither gave thanks; but became vain in their reasonings and their senseless heart was darkened. Professing themselves to be wise, they became fools. And even as they refused to have God in their knowledge, God gave them up to a reprobate mind, to do those things which are not fitting; being filled with all unrighteousness."[11] And then follows the dark picture, from which we revolt but which the ancient historians themselves justify.
