For Sanger, the solution lies in the field of evolutionary biology. Like many contemporary thinkers, he seems to have had a bit of a eureka moment in exploring this trendy academic field, which holds that people are motivated, in pretty much everything they do, by the urge to reproduce. Sanger argues that abortion does serve this aim; although it’s a little counterintuitive, he argues that terminating a pregnancy can serve the overall aim of procreation. We are all, he writes, reproductive strategists now; we all want to reproduce successfully, and abortion can help us get there by ensuring (1) that a woman doesn’t have too many children too close together, which is unhealthy for her and for them; and (2) that she doesn’t have to bear a child under adverse circumstances. Abortion, he contends, often happens when a woman has chosen the wrong partner or gotten pregnant at the wrong time. It lets her “get back in the game” and conceive under better conditions.

In short, Sanger is arguing, a little coldbloodedly, that sacrificing a potential child is sometimes necessary for children and families in general to flourish. Treading rather carefully, he concedes the antiabortion point that unborn life is life, but goes on to argue that this life can and does at times represent a threat to other lives, a challenge to the mother’s health and to the existing family order.
