For a clear and illuminating account of the creative and dynamic power of the endocrine glands, the layman is referred to a recently published book by Dr. Louis Berman.(2) This authority reveals anew how body and soul are bound up together in a complex unity. Our spiritual and psychic difficulties cannot be solved until we have mastered the knowledge of the wellsprings of our being. "The chemistry of the soul! Magnificent phrase!" exclaims Dr. Berman. "It's a long, long way to that goal. The exact formula is as yet far beyond our reach. But we have started upon the long journey, and we shall get there. "The internal secretions constitute and determine much of the inherited powers of the individual and their development. They control physical and mental growth, and all the metabolic processes of fundamental importance. They dominate all the vital functions of man during the three cycles of life. They cooperate in an intimate relationship which may be compared to an interlocking directorate. A derangement of their functions, causing an insufficiency of them, an excess, or an abnormality, upsets the entire equilibrium of the body, with transforming effects upon the mind and the organs. In short, they control human nature, and whoever controls them, controls human nature.... "Blood chemistry of our time is a marvel, undreamed of a generation ago. Also, these achievements are a perfect example of the accomplished fact contradicting a prior prediction and criticism. For it was one of the accepted dogmas of the nineteenth century that the phenomena of living could never be subjected to accurate quantitative analysis." But the ethical dogmas of the past, no less than the scientific, may block the way to true civilization. Physiologically as well as psychologically the development of the human being, the sane mind in the sound body, is absolutely dependent upon the functioning and exercise of all the organs in the body. The "moralists" who preach abstinence, self-denial, and suppression are relegated by these findings of impartial and disinterested science to the class of those educators of the past who taught that it was improper for young ladies to indulge in sports and athletics and who produced generations of feeble, undeveloped invalids, bound up by stays and addicted to swooning and hysterics. One need only go out on the street of any American city to-day to be confronted with the victims of the cruel morality of self-denial and "sin." This fiendish "morality" is stamped upon those emaciated bodies, indelibly written in those emasculated, underdeveloped, undernourished figures of men and women, in the nervous tension and unrelaxed muscles denoting the ceaseless vigilance in restraining and suppressing the expression of natural impulses.
