The profoundest achievement of the physiologist will be the change his teachings and discoveries will bring about in man’s attitude toward himself.  When he comes to realize himself as a chemical machine that can, within limits, be remodeled, overhauled and repaired, as an automobile can be, within limits, when he becomes saturated with the significance of his endocrine-vegetative system at every turn and move of his life, and when sympathy and pity informed by knowledge and understanding will come to regulate his relationships with the lowest and most despised of the men, women and children about him, the era of the first real civilization will properly be said to be born.

Morality, as society’s code of conduct for its members, will have to change in the direction of a greater flexibility with the establishment of organic differences in human types.  There is nothing that is more emphasized to the pathologist than that one man’s meat is another man’s poison.  In the family, as nature’s laboratory for the manufacture of fresh combinations of the internal secretions, allowances will be made for divergences in capacity and deportment from a new angle altogether.  Schools will function as the developers, stimulators and inhibitors of the endocrines, as well as investigators of the individuals who have not enough or too much of one or some of them.  Prisons will have the same function, only they will be named detention hospitals.  The raising of the general level of intelligence by the judicious use of endocrine extracts will mean a good deal to the sincere statesman.  The average duration of life will be prolonged for an enormous mass of the population.  If the prevention of war depends upon the burning into the imagination of the electorates what the consequences of war are, a high intelligence quotient and revaluation of life will count for a good deal.

Man is the animal that wants Utopia.  So long as human nature was looked upon as fixed constant in the ebb and flow of life, a Utopia of fine minds could be conceived only by the dreamer and poet.  The desire for such a Utopia could only be regarded as a tragic aspiration for an impossibility.  The physiology of the internal secretions teaches that human nature does change and can be changed.  A relative control of its properties is already in view.  The absolute control will come.

Nor need anyone fear that the science of the internal secretions in its maturity will signify the abolition of the marvelous differences between human beings that create the unique personalities of history.  A derangement of the endocrines has been responsible for masterpieces of the human species in the past and will be responsible for them in the future.  The equality of Utopia can be the equality of the highest and fullest development possible for each of its inhabitants.  The applications of endocrine control will not necessarily interfere with the life of the individual.  There will be breeding of the best mixtures of glands of internal secretion possible.  And there will be treatment for those born with a handicap, or who have become handicapped in the life struggle.  There will be a stimulation of capacity to the limit.  But beyond that, compulsory equalization is a theorist’s bogey.
