Abstract

I argue against responsibility arguments that offer a defence of abortion even on the assumption that the fetus is a person. I focus on argumentation originally offered by Judith Jarvis Thomson and then later defended by David Boonin. I offer thought experiments meant to show that, under certain conditions, one bears moral responsibility for creating a fetus. I then offer a positive argument for when one is morally responsible for the creation of a fetus. This argument relies on the presence of other forms of sex that reasonably approximate the goods of penile-vaginal intercourse. Given the presence of these options, sexual partners who engage in penile-vaginal intercourse bear moral responsibility for the creation of the fetus. While I do not think this argument settles the abortion debate – there still may be other ways to successfully defend abortion – it does explain why responsibility arguments like those offered by Thomson fail.
