Michael Tooley on Infantacide and Taboos
"Abortion and Infanticide" in Ethics in Perspective, Kirsten J. Struhl & Paula Rothenberg Struhl, eds. (Random House: 1975) p.245.
Aside from the light it may shed on the abortion question, the issue of infantacide is both interesting and important in its own right. The theoretical interest has been mentioned: it forces one to face up to the question of what makes something a person. The practical imprtance need not be labored. Most people would prefer to raise children who do not suffer from gross deformities or from severe physical, emotional, or intellectual handicaps. If it could be shown that there is no moral objection to infanticide the happiness of society could be significantly and justifably increased. Infanticide is also of interest because of the strong emotions it arouses. The typical reaction to infanticide is like the reaction to incest or cannibalism, or the reaction of previous generations to masturbation or oral sex. The response, rather than appealing to carefully formulated moral principles, is primarily visceral. When philosophers themselves respond in this way, offering no arguments, and dismissing infanticide out of hand, it is reasonable to suspect that one is dealing with a taboo rather than with a rational prohibition.
