But let us be charitable—and serious. What Mr. Burroughs instances as acts of instinct certainly are acts of instincts. By the same method of logic one could easily adduce a multitude of instinctive acts on the part of man and thereby prove that man is an unreasoning animal. But man performs actions of both sorts. Between man and the lower animals Mr. Burroughs finds a vast gulf. This gulf divides man from the rest of his kin by virtue of the power of reason that he alone possesses. Man is a voluntary agent. Animals are automatons. The robin fights its reflection in the window-pane because it is his instinct to fight and because he cannot reason out the physical laws that make this reflection appear real. An animal is a mechanism that operates according to fore-ordained rules. Wrapped up in its heredity, and determined long before it was born, is a certain limited capacity of ganglionic response to eternal stimuli. These responses have been fixed in the species through adaptation to environment. Natural selection has compelled the animal automatically to respond in a fixed manner and a certain way to all the usual external stimuli it encounters in the course of a usual life. Thus, under usual circumstances, it does the usual thing. Under unusual circumstances it still does the usual thing, wherefore the highhole perforating the ice-house is guilty of lunacy—of unreason, in short. To do the unusual thing under unusual circumstances, successfully to adjust to a strange environment for which his heredity has not automatically fitted an adjustment, Mr. Burroughs says is impossible. He says it is impossible because it would be a non-instinctive act, and, as is well known animals act only through instinct. And right here we catch a glimpse of Mr. Burroughs’s cart standing before his horse. He has a thesis, and though the heavens fall he will fit the facts to the thesis. Agassiz, in his opposition to evolution, had a similar thesis, though neither did he fit the facts to it nor did the heavens fall. Facts are very disagreeable at times.
But let us see. Let us test Mr. Burroughs’s test of reason and instinct. When I was a small boy I had a dog named Rollo. According to Mr. Burroughs, Rollo was an automaton, responding to external stimuli mechanically as directed by his instincts. Now, as is well known, the development of instinct in animals is a dreadfully slow process. There is no known case of the development of a single instinct in domestic animals in all the history of their domestication. Whatever instincts they possess they brought with them from the wild thousands of years ago. Therefore, all Rollo’s actions were ganglionic discharges mechanically determined by the instincts that had been developed and fixed in the species thousands of years ago. Very well. It is clear, therefore, that in all his play with me he would act in old-fashioned ways, adjusting himself to the physical and psychical factors in his environment according to the rules of adjustment which had obtained in the wild and which had become part of his heredity.
Rollo and I did a great deal of rough romping. He chased me and I chased him. He nipped my legs, arms, and hands, often so hard that I yelled, while I rolled him and tumbled him and dragged him about, often so strenuously as to make him yelp. In the course of the play many variations arose. I would make believe to sit down and cry. All repentance and anxiety, he would wag his tail and lick my face, whereupon I would give him the laugh. He hated to be laughed at, and promptly he would spring for me with good-natured, menacing jaws, and the wild romp would go on. I had scored a point. Then he hit upon a trick. Pursuing him into the woodshed, I would find him in a far corner, pretending to sulk. Now, he dearly loved the play, and never got enough of it. But at first he fooled me. I thought I had somehow hurt his feelings and I came and knelt before him, petting him, and speaking lovingly. Promptly, in a wild outburst, he was up and away, tumbling me over on the floor as he dashed out in a mad skurry around the yard. He had scored a point.
After a time, it became largely a game of wits. I reasoned my acts, of course, while his were instinctive. One day, as he pretended to sulk in the corner, I glanced out of the woodshed doorway, simulated pleasure in face, voice, and language, and greeted one of my schoolboy friends. Immediately Rollo forgot to sulk, rushed out to see the newcomer, and saw empty space. The laugh was on him, and he knew it, and I gave it to him, too. I fooled him in this way two or three times; then be became wise. One day I worked a variation. Suddenly looking out the door, making believe that my eyes had been attracted by a moving form, I said coldly, as a child educated in turning away bill-collectors would say: “No my father is not at home.” Like a shot, Rollo was out the door. He even ran down the alley to the front of the house in a vain attempt to find the man I had addressed. He came back sheepishly to endure the laugh and resume the game.
And now we come to the test. I fooled Rollo, but how was the fooling made possible? What precisely went on in that brain of his? According to Mr. Burroughs, who denies even rudimentary reasoning to the lower animals, Rollo acted instinctively, mechanically responding to the external stimulus, furnished by me, which led him to believe that a man was outside the door.
Since Rollo acted instinctively, and since all instincts are very ancient, tracing back to the pre-domestication period, we can conclude only that Rollo’s wild ancestors, at the time this particular instinct was fixed into the heredity of the species, must have been in close, long-continued, and vital contact with man, the voice of man, and the expressions on the face of man. But since the instinct must have been developed during the pre-domestication period, how under the sun could his wild, undomesticated ancestors have experienced the close, long-continued, and vital contact with man?
Mr. Burroughs says that “instinct suffices for the animals,” that “they get along very well without reason.” But I say, what all the poor nature-fakers will say, that Rollo reasoned. He was born into the world a bundle of instincts and a pinch of brain-stuff, all wrapped around in a framework of bone, meat, and hide. As he adjusted to his environment he gained experiences. He remembered these experiences. He learned that he mustn’t chase the cat, kill chickens, nor bite little girls’ dresses. He learned that little boys had little boy playmates. He learned that men came into back yards. He learned that the animal man, on meeting with his own kind, was given to verbal and facial greeting. He learned that when a boy greeted a playmate he did it differently from the way he greeted a man. All these he learned and remembered. They were so many observations—so many propositions, if you please. Now, what went on behind those brown eyes of his, inside that pinch of brain-stuff, when I turned suddenly to the door and greeted an imaginary person outside? Instantly, out of the thousands of observations stored in his brain, came to the front of his consciousness the particular observations connected with this particular situation. Next, he established a relation between these observations. This relation was his conclusion, achieved, as every psychologist will agree, by a definite cell-action of his grey matter. From the fact that his master turned suddenly toward the door, and from the fact that his master’s voice, facial expression, and whole demeanour expressed surprise and delight, he concluded that a friend was outside. He established a relation between various things, and the act of establishing relations between things is an act of reason—of rudimentary reason, granted, but none the less of reason.
Of course Rollo was fooled. But that is no call for us to throw chests about it. How often has every last one of us been fooled in precisely similar fashion by another who turned and suddenly addressed an imaginary intruder? Here is a case in point that occurred in the West. A robber had held up a railroad train. He stood in the aisle between the seats, his revolver presented at the head of the conductor, who stood facing him. The conductor was at his mercy.
But the conductor suddenly looked over the robber’s shoulder, at the same time saying aloud to an imaginary person standing at the robber’s back: “Don’t shoot him.” Like a flash the robber whirled about to confront this new danger, and like a flash the conductor shot him down. Show me, Mr. Burroughs, where the mental process in the robber’s brain was a shade different from the mental processes in Rollo’s brain, and I’ll quit nature-faking and join the Trappists. Surely, when a man’s mental process and a dog’s mental process are precisely similar, the much-vaunted gulf of Mr. Burroughs’s fancy has been bridged.
I had a dog in Oakland. His name was Glen. His father was Brown, a wolf-dog that had been brought down from Alaska, and his mother was a half-wild mountain shepherd dog. Neither father nor mother had had any experience with automobiles. Glen came from the country, a half-grown puppy, to live in Oakland. Immediately he became infatuated with an automobile. He reached the culmination of happiness when he was permitted to sit up in the front seat alongside the chauffeur. He would spend a whole day at a time on an automobile debauch, even going without food. Often the machine started directly from inside the barn, dashed out the driveway without stopping, and was gone. Glen got left behind several times. The custom was established that whoever was taking the machine out should toot the horn before starting. Glen learned the signal. No matter where he was or what he was doing, when that horn tooted he was off for the barn and up into the front seat.
