his own unique way — with his special senses, his biochemical makeup, his physique and temperament, and nobody else’s. No amount of scientific explanation, however comprehensive, can explain away these self-evident facts. And let us remember that Professor Skinner’s scientific portrait of man as the product of the social environment is not the only scientific portrait. There are other, more realistic likenesses. Consider, for example, Professor Roger Williams’ portrait What he paints is not behavior in the abstract, but mind-bodies behaving — mind-bodies that are the products partly of the environment they share with other mind-bodies, partly of their own private heredity. In The Human Frontier and Free but Unequal Professor Williams has expatiated, with a wealth of detailed evidence, on those innate differences between individuals, for which Dr. Watson could find no support and whose importance, in Professor Skinner’s eyes, approaches zero. Among animals, biological variability within a given species becomes more and more conspicuous as we move up the evolutionary scale. This biological variability is highest in man, and human beings display a greater degree of biochemical, structural and temperamental diversity than do the members of any other species. This is a plain observable fact. But what I have called the Will to Order, the desire to impose a comprehensible uniformity upon the bewildering manifoldness of things and events, has led many people to ignore this fact. They have minimized biological uniqueness and have concentrated all their attention upon the simpler and, in the present state of knowledge, more understandable environmental factors involved in human behavior. “As a result of this environmentally centered thinking and investigation,” writes Professor Williams, “the doctrine of the essential uniformity of human infants has been widely accepted and is held by a great body of social psychologists, sociologists, social anthropologists, and many others, including historians, economists, educationalists, legal scholars and men in public life. This doctrine has been incorporated into the prevailing mode of thought of many who have had to do with shaping educational and governmental policies and is often accepted unquestioningly by those who do little critical thinking of their own.”
An ethical system that is based upon a fairly realistic appraisal of the data of experience is likely to do more good than harm. But many ethical systems have been based upon an appraisal of experience, a view of the nature of things, that is hopelessly unrealistic. Such an ethic is likely to do more harm than good. Thus, until quite recent times, it was universally believed that bad weather, diseases of cattle and sexual impotence could be, and in many cases actually were, caused by the malevolent operations of magicians. To catch and kill magicians was therefore a duty — and this duty, moreover, had been divinely ordained in the second Book of Moses: “Thou shalt not suffer a witch to live.” The systems of ethics and law that were based upon this erroneous view of the nature of things were the cause (during the centuries, when they were taken most seriously by men in authority) of the most appalling evils. The orgy of spying, lynching and judicial murder, which these wrong views about magic made logical and mandatory, was not matched until our own days, when the Communist ethic, based upon erroneous views about economics, and the Nazi ethic, based upon erroneous views about race, commanded and justified atrocities on an even greater scale. Consequences hardly less undesirable are likely to follow the general adoption of a Social Ethic, based upon the erroneous view that ours is a fully social species, that human infants are born uniform and that individuals are the product of conditioning by and within the collective environment. If these views were correct, if human beings were in fact the members of a truly social species, and if their individual differences were trifling and could be completely ironed out by appropriate conditioning,
