Consider a defense of abortion which I have never heard anyone present. I present it to show the baneful distortions in thinking stemming from accepting the moral neutrality of sexuality.
Abortion is categorically prohibited even for pregnancies resulting from incest or rape. Abortions are direct intentional stopping a human life. It is a hard teaching. Much grievous individual and social pain is eliminable by some abortions.
Why do so many decent people ignore the fact that abortion is an intentional direct taking of a human life? Many of my fellow Catholics simply will not look at abortion as murder. They look only at the problems to be solved by termination of a pregnancy. Anecdotal evidence suggests that most of these decent people also accept the moral neutrality of sexuality. What I want to show is that looking at pregnancy in a certain way along with accepting the moral neutrality of sexuality provides a moral defense of abortion. If people unconsciously look at pregnancy in this certain way to justify abortion, then we have an explanation of why decent people vigorously defend abortion.
What is this special way of looking at pregnancy? It is looking at pregnancy as a continuation of coitus. Of course, this is far fetched but not totally incoherent. When exactly does coitus end? Upon ejaculation the male might be pretty well finished. But coitus is a mutual act and it is not clear that the woman’s part is over once the man withdraws. It is possible to consider fertilization as a continuation of a single mutual action of ovulation and ejaculation. I do not want to continue with details because this is all fuzzy thinking. The point I want to make is that there is a line of loose unconscious thinking which connects pregnancy primarily with sexuality for moral purposes. Indeed the exception some ardent pro-lifers grant to allow abortions for pregnancy starting from an incestual coitus or rape suggests that they may be identifying these pregnancies as parts of impermissible sex acts.
If pregnancy, for moral purposes, is looked at primarily as a condition connected with the coitus initiating it, then continuation or termination of the pregnancy falls under sexual morality. In the very widely held stance of moral neutrality of sexuality, viz., there are no categorical prohibitions of any sexual act, then abortion is open to being justified by references to its consequences.
An ultra sound is a fact check showing that pregnancy is no longer a matter of sexual morality.
