I. The Conflict of Science and Tradition.
The doctrine that on mankind’s account all other beings came into existence, and that non-human beings are mere hunks of matter devoid of all psychic qualities found in man, is a doctrine about as sagacious as the old geocentric theory of the universe. Conceit is a distinctly human emotion. No other animal has it. But it has been lavished upon man with a generosity sufficient to compensate for its total absence from the rest of the universe. Man has always overestimated himself. In whatever age or province of the world you look down on the human imagination, you find it industriously digging disparities and establishing gulfs. Man, according to himself, has had great difficulty many times in the history of the world in escaping the divine. According to the facts, he has only in recent biological times and after great labour and uncertainty abandoned his tail and his all-fours. According to himself, man was made ‘in the image of his maker,’ and has been endowed with powers and properties peculiarly his own. According to the facts, he has come into the world in a manner identical with that of all other animals, and has been endowed with like nature and destiny. Man has never manifested a warmer or more indelicate enthusiasm than the enthusiasm with which he has appreciated himself. And with the same ardour with which he has praised himself he has maligned and misrepresented others. Man has set himself up as the supreme judge and executive of the world, and he has not hesitated to award to himself the lion’s share of everything. He has ransacked his fancy for adjectives with which to praise himself, and driven his inventive faculties to the verge of distraction in search of justification for his crimes upon those around him. Every individual bent on deeds of darkness first seeks in his own mind justification for his purposed sins. And it is a caustic comment on the character of human conviction that no enthusiastic criminal—from the marauder of continents to the kitchen pilferer—ever yet sought unsuccessfully at the court of his conscience for a sinful permit. It was an easy matter, therefore, for man—aided as he was by such an experienced imagination—to convince himself that all other animals were made for him, that they were made without feeling or intelligence, and that hence he was justified in using in any way he chose the conveniences so generously provided by an eccentric providence. But Darwin has lived. Beings have come into the world, we now know, through the operation of natural law. Man is not different from the rest. The story of Eden is a fabrication, bequeathed to us by our well-meaning but dimly-lighted ancestors. There has been no more miracle in the origin of the human species than in the origin of any other species. And there is no more miracle in the origin of a species than there is in the birth of a molecule or in the breaking of a tired wave on the beach. Man was not made in the image of the hypothetical creator of heaven and earth, but in the image of the ape. Man is not a fallen god, but a promoted reptile. The beings around him are not conveniences, but cousins. Instead of stretching away to the stars, man’s pedigree slinks down into the sea. Horrible revelation! Frightful antithesis! Instead of celestial genesis and a ‘fall’—long and doleful promotion. Instead of elysian gardens and romance—the slime. Instead of a god with royal nostrils miraculously animating an immortal duplicate—a little lounging cellule, too small to be seen and too senseless to distinguish between midnight and noon. But the situation is not half so horrible as it looks to be to those who see only the skin of things. Is it not better, after all, to be the honourable outcome of a straightforward evolution than the offspring of flunky-loving celestials? Are the illustrious children of the ape less glorious than the sycophants of irrational theological systems? Darwin dealt in his quiet way some malicious blows to human conceit, but he also bequeathed to a misguided world the elements of its ultimate redemption.
The supposed psychical gulf between human and non-human beings has no more existence, outside the flamboyant imagination of man, than has the once-supposed physical gulf. It is pure fiction. The supposition is a relic of the rapidly dwindling vanity of anthropocentricism, and is perpetuated from age to age by human selfishness and conceit. It has no foundation either in science or in common-sense. Man strives to lessen his guilt by the laudation of himself and the disparagement and degradation of his victims. Like the ostrich, who, pursued by death, improvises an imaginary escape by plunging its head into the desert, so man, pursued by the vengeful correctives of his own conscience, fabricates a fictitious innocence by the calumniation of those upon whom he battens. But such excuses cannot much longer hold out against the rising consciousness of kinship. Psychology, like all other sciences, is rapidly ceasing to attend exclusively to human phenomena. It is lifting up its eyes and looking about; it is preparing to become comparative. It has come to realise that the mind of man is but a single shoot of a something which ramifies the entire animal world, and that in order to understand its subject it is necessary for it to familiarise itself with the whole field of phenomenon. The soul of man did not commence to be in the savage. It commenced to be in the worm, whose life man grinds out with his heel, and in the bivalve that flounders in his broth. The roots of consciousness are in the sea. Side by side with physical evolution has gone on psychical evolution; side by side with the evolution of organs and tissues has gone on the evolution of intellect, sensibility, and will. Human nature and human mind are no more sui generis than are human anatomy and physiology. The same considerations that prove that man’s material organism is the cumulative result of long evolution proclaim that human mind, the immaterial concomitant of the material organism, is also the cumulative result of long evolution.
We might just as well recognise facts first as last, for they will have to be recognised some time. Truths are not put down by inhospitality—they are simply put off. The universe has a policy, a program. We may close our eyes to the facts around us, hoping in this way to compel them to pass away or be forgotten. But they do not pass away, nor will they be forgotten. They simply become invisible. They will live on and present themselves to other minds or ages or climes more hospitable or honest than our own. The only proper attitude of mind to assume toward the various doctrines existing among men is the attitude of perfect willingness to believe anything—anything that appeals to us as being reasonable and right. The great majority of men, however, are intellectual solids—unable to move and unwilling to think. They have certain beliefs to which they are determined to hold on, and everything that does not fit in with these beliefs is rejected as a matter of course.
