"The struggle for contraception was to last longer and be more difficult than the struggle for abortion. To change a famous saying: We had won the war, the only thing left was to fight the last battle. "The relation between contraception and abortion is clear. It is the same as that between a war and the ultimate battle: The final goal, as already seen, is to exercise freedom over one's own body as a piece of material "in the ecological meaning of the word." In other words: Once contraception is common in society, it brings about a new way of thinking; the body is seen as biological material with which one can do as one pleases. As this mentality spreads, abortion is increasingly accepted. History has proven Simon to be right. In December 1967, nine months before the encyclical Humanae Vitae was issued, the Neuwirth Law was passed in France allowing the sale and advertising of contraceptives. In 1975, the Weil Law followed, which legalized abortion. By 1983 this "unspeakable crime" (Gaudium et spes, No. 51) was paid for by national health insurance - that is, by all taxpayers. The Weil Law's "conscience clause" (allowing for refusal to participate in abortion) is no more than an empty formality, since all French citizens, whatever their convictions, pay for health insurance and so participate in the funding of abortion. By refusing to acknowledge the inviolable right to life, the government has become, in effect, a totalitarian State."
