"To sum up then, the best solution for ensuring world peace is the widespread promotion of contraception or abortion. Abortion is a drastic measure and can involve serious emotional disturbance. Furthermore, once a zygote has been formed by the act of fertilization it constitutes a new individual member of society, and its destruction is, in effect, an act of aggression, which is the very pattern of behaviour that we are attempting to control. Contraception is obviously preferable, and any religious or other ‘moralizing’ factions that oppose it must face the fact that they are engaged in dangerous war-mongering."
