The work investigates the sexual impulse not as an isolated biological phenomenon, but as a deeply social force intertwined with human history, law, and morality. The author begins by examining the profound role of motherhood and the child's right to proper ancestry and early care, emphasizing the absolute necessity of maternal rest and hygiene. The discussion then moves to sexual education, arguing against the traditional doctrine of silence and demanding an open, natural approach to the physical facts of life from early childhood through puberty. The text addresses the psychological significance of nakedness, challenging conventional prudery and demonstrating how familiarity with the human form promotes health and purity of thought.
Subsequent sections tackle the difficult problems of chastity, sexual abstinence, and the complex historical evolution of prostitution and venereal disease, advocating for medical and social reform rather than blind punishment. The study culminates in an extensive analysis of marriage and the art of love, proposing that true stability in human relationships depends upon personal freedom, mutual respect, and the conscious recognition of psychological and physiological differences between the sexes. The author ultimately asserts that society must replace rigid, negative prohibitions with positive ideals of responsibility and human development.
