Like all other education, that of sex can be rendered effective and valuable only as it meets and satisfies the interests and demands of the pupil himself. It cannot be imposed from without, handed down from above, superimposed upon the intelligence of the person taught. It must find a response within him, give him the power and the instrument wherewith he may exercise his own growing intelligence, bring into action his own judgment and discrimination and thus contribute to the growth of his intelligence. The civilized world is coming to see that education cannot consist merely in the assimilation of external information and knowledge, but rather in the awakening and development of innate powers of discrimination and judgment. The great disaster of "sex education" lies in the fact that it fails to direct the awakened interests of the pupils into the proper channels of exercise and development. Instead, it blunts them, restricts them, hinders them, and even attempts to eradicate them. This has been the great defect of sex education as it has been practised in recent years. Based on a superficial and shameful view of the sexual instinct, it has sought the inculcation of negative virtues by pointing out the sinister penalties of promiscuity, and by advocating strict adherence to virtue and morality, not on the basis of intelligence or the outcome of experience, not even for the attainment of rewards, but merely to avoid punishment in the form of painful and malignant disease. Education so conceived carries with it its own refutation. True education cannot tolerate the inculcation of fear. Fear is the soil in which are implanted inhibitions and morbid compulsions. Fear restrains, restricts, hinders human expression. It strikes at the very roots of joy and happiness. It should therefore be the aim of sex education to avoid above all the implanting of fear in the mind of the pupil. Restriction means placing in the hands of external authority the power over behavior. Birth Control, on the contrary, implies voluntary action, the decision for one's self how many children one shall or shall not bring into the world. Birth Control is educational in the real sense of the word, in that it asserts this power of decision, reinstates this power in the people themselves.
