ABSTRACT
While the changes which modernity implies affect the premises of all human conduct, the problem as a whole engages the attention of relatively few persons. The larger number of men and women living within the orbit of die Great Society are no doubt aware that their inherited beliefs about religion, politics, business, and sex do not square entirely with the actual beliefs upon which they feel compelled to act. The Biblical account of how Jehovah slew Onan for disobeying his father's commandment to go to his brother's widow, Tamar, and "perform the duty of a husband's brother", shows that the deliberate prevention of conception is not a new discovery. With contraception established as a more or less legitimate idea in modern society, a vast discussion has ensued as to how the practice of it can be rationalized. As a preparation for the vocation of parenthood it is proposed to educate both men and women in the care.
