"Abortion is wrong because of the most simple, obvious, and universally accepted of all moral principles: the Golden Rule, 'Do unto others what you would have them do unto you, and do not do unto others what you would not have them do unto you.' Combine this principle, as one premise, with the fact that a human fetus is a fetal human, a human being, as the other premise, and you get the conclusion that abortion is wrong."
-- Peter Kreeft (Three Approaches to Abortion, p. 31)
