Abstract
There is an argument against abortion that should be rejected. It is the argument that abortion is the killing of an innocent human being, and since the killing of an innocent human being is immoral, abortion is therefore immoral. The major premise should be corrected to read: ?Generally speaking, the killing of innocent human beings is immoral'; for in some situations morality demands the killing of the innocent. Moreover, given the deep structure of English and the differences between unborn and born progeny, the question of whether a human fetus is a human being is best answered in the negative
