Is the abortion debate over?

Micah Watson has some thoughts, here, at Public Discourse:

The lines of disagreement in the philosophical debate over abortion have never been clearer. While the politics of abortion remain as tumultuous and contested as they have ever been, the underlying philosophical, ethical, and scientific issues have been clarified to the extent that any careful person can examine the arguments of both sides and come to a principled and informed position.

This has not always been the case. . . .

 . . . the philosophical debate about the normative dimensions of the abortion issue still comes down to the aforementioned watershed difference: either human beings as such have a right to life, or some human beings have a right to life and are thus persons, and some are not and are thus expendable.

While pro-life philosophers must continue their work by applying principles to emerging bioethical questions, the argumentative clarity achieved by their work in the abortion debate has implications for pro-lifers who seek to continue to influence both the law and the culture. Perhaps the most important implication is also the most obvious. If the philosophical debate about abortion is over, the political debate remains.
