The ethical indefensibility of heartbeat bills.

Recently, several states in the United States have sought to adopt more restrictive abortion policies. Most have tried to enact "heartbeat bills" that prohibit most abortions once a fetal heartbeat becomes detectable. This article explores this question: Are heartbeat bills ethically defensible? I argue that they are not. There are at least four problems with them. First, heartbeat bills rely on a problematic understanding of human death. Second, they contradict and even undermine the leading arguments in ethics against abortion. Third, they are ambiguous not just in terms of when they judge fetal heartbeats to be detectable but also in what they deem to be heartbeats. Finally, there is a case to be made that heartbeat bills are disingenuous, both in their intentions and in their underlying motives.
