In a four part series, Francis Beckwith addresses the primary arguments offered on behalf of legal abortion: “The pro-life position is subject to somewhat varying formulations. The most widely accepted and representative of these can be defined in the following way: The unborn entity is fully human from the moment of conception. Abortion (narrowly defined) results in the intentional death of the unborn entity. Therefore, abortion entails the intentional killing of a human being. This killing is in most cases unjustified, since the unborn human being has a full right to life. If, however, there is a high probability that a woman’s pregnancy will result in her death (as in the case of a tubal pregnancy, for example), then abortion is justified. For it is a greater good that one human should live (the mother) rather than two die (the mother and her child). Or, to put it another way, in such cases the intent is not to kill the unborn (though that is an unfortunate effect) but to save the life of the mother. With the exception of such cases, abortion is an act in which an innocent human being is intentionally killed; therefore, abortion should be made illegal, as are all other such acts of killing. This is the pro-life position I will be defending in this series.” Parts: “The Appeal to Pity“, “Arguments from Pity, Tolerance, and Ad Hominem“, “Is The Unborn Human Less Than Human?“, and “When Does a Human Become a Person?“.
