These are not “gotcha questions”; they are ones I have struggled with for as long as I’ve thought through where I stand on abortion, and I’ve tried to remain open to corrections in my thinking. I’m not comfortable with those who are unwilling to grant any concessions to the other side or acknowledge difficulties inherent in their own position. But I’m not comfortable with my own position, either—thinking about abortion taking place on a continuum, and troubled by abortions, particularly later in pregnancy, as the child develops.

The question I can’t answer is where the moral inflection point is, when the fetus starts to have claims of its own, including the right to life. Does it depend on fetal development? If so, what aspect of fetal development? Brain waves? Feeling pain? Dreaming? The development of the spine? Viability outside the womb? Something else? Any line I might draw seems to me entirely arbitrary and capricious.

Because of that, I consider myself pro-life, but with caveats. My inability to identify a clear demarcation point—when a fetus becomes a person—argues for erring on the side of protecting the unborn. But it’s a prudential judgment, hardly a certain one.
