But these fallacies do not usually travel alone. Watsonianism in particular is fond of the company of facts. It mixes up Behaviorism, as a mere study of behavior, in a vast confusion of Psychology, Physiology, Ethics and irreligion. It seeks now to blind us with passion, now to swamp us in detail--lest we remember what we are talking about. Thus Dr. Watson’s great book bristles with facts--pages and pages of them taken straight from physiology. He divides our bodies into three groups of parts, according to function--receptors, conductors and effectors. The receptors receive impressions from the outer world and are nothing but our old friends, the five senses--eyes, ears, nose, the taste-buds of the tongue, and those areas (chiefly of cuticle) which are sensitive to touch. The conductors are the nerves. The effectors, or the bringers about of effects, are the muscles and glands. Now the glands, at least those of the endocrine or ductless variety, are comparatively new-comers in the world of knowledge. But the other things are as familiar as doctors’ bills. There have been changes in nomenclature, nothing more. Yet these changes are significant. Receptors take the place of the senses because (in all seriousness) the behaviorist wishes to get rid of that hateful word “sense” and its implications. A similar motive must have been active when it came to naming the secretions from the ductless glands. They used to be called Hormones, meaning “I stir up.” This no doubt was objectionable, because some of the hormones do not stir us up; they quiet us down. Dr. Watson knows them all as autocoids, which has the advantage of being non-committal in this regard. What is more to the point, it implies something automatic. Let us see how they work. But right here we are met by a lack of knowledge. The secretions from only a few of the endocrines (notably andrenin and thyroxin) have as yet been isolated and analyzed. But there is good reason for believing that they regulate, to a certain extent at least, not only the ductless glands among themselves but (through the sympathetic nerves) the action of the unstriped muscles which control the stomach, intestines and various other unconscious or vegetative processes. Autocoidal secretion seems to be very much at the beck and call of our emotions, or else our emotions are very much at the beck and call of our autocoids; but whether you hitch the cart before the horse or the horse before the cart, the believer in human freedom need be no more alarmed over the autocoids than he is over the fact that drugs have certain effects when taken into the system. It was known even in the ages of faith that a man was not quite himself after partaking too freely even of a drug so charmingly outward mannered as is alcohol.
