One of the things which might modify this supreme romantic estimate of himself, if such a thing were either desirable or possible, would be an even slightly technical examination of the process by which he arrives, as well as the extreme simplicity of the mechanical and chemical formula by which, throughout endless ages, he and all his fellows have been created. There is no longer any vast mystery about it; we are even getting relatively close to the secret, or could if we were permitted to go on undisturbed for a period by wars, let us say, or religious and educational illusions and furies (put forward by what? How brought about?), a persistent inherent mass opposition to thought and change in man himself. What subtle force ever invented that as a race quieter? As biologists and anthropologists present man and his allied species, the original type structure on which all are more or less modeled is not so wonderful: two eyes, two ears, two nostrils, two feet and two hands or four feet, two of them antecedents of the present hands; or two feet and two wings, the latter successors of former feet; a lung or air-breathing system, not unlike that of any tree or plant; a root or arterial system, modified to meet various conditions and situations as in birds, fishes, moles; a nervous or sensory system of an allied character--no marked diversity in anything indeed, and all brought about by the inescapable chemical and physical reactions and compulsions of seemingly blind forces, as Crile and Loeb have shown. Even now chemists and physicists are at work upon the balances and equations involved in the mechanical and chemical construction of man, the leverage by which he moves, the combinations which control his form or aspect, as well as the chemical combinations which can induce motion or self-propulsion. Even as to his so-called thought how close are the Behaviorists to the material mechanics which produce it? His thoughts also are apparently little more than compelled reactions of one chemical upon another which he can no more escape than can he his form or motions. The one unsolved mystery apparently is why a machine so easily made and controlled should be able to speculate as to the reason for his being or to worry over it.
