Written in 1903 by one of the first women Doctors. Her views are still salient now. KAREZZA, elucidating a theory of conjugal life, in which there is a love communion between husband and wife from which results a mastery of the physical and complete control of the fecundating power. KAREZZA gives a high ideal to parental functions; pleads for justice to the unborn child; teaches that the control of procreation is possible with every husband and wife; gives honor to womanhood, and, most of all, controverts the prevailing ideas of baseness and degradation associated with the sexual nature. KAREZZA may be considered a supplement to TOKOLOGY, and like that, deals with tested theories and practical truths. They have been lived and demonstrated, and are here presented as living facts. Men and women must learn the significance of the sexual relation, and its possible influence upon life and character. Copulation is more than a propagative act; it is a blending of body, soul and spirit, ennobling or degrading according to the attitude of the participants. For both husband and wife it has a function in soul development that hitherto has been prevented and perverted by the traditional uncleanness attached to the relation. Nature made but one mistake in the evolution of life, according to manÂ's edict, and that is in creating the human reproductive organs. Reverse this edict. Let the search-light of truth illumine this subject, and a satisfactory solution of many social problems will be evolved. No part of the body should be under condemnation. The young should be enlightened upon these important subjects, while the knowledge of sexual science will open the door for the true marriage. KAREZZA makes a plea for a better birthright for the child, and aims to lead individuals to seek a higher development of themselves through the most sacred relation.
