Abstract
Arguments that claim opponents of abortion are inconsistent in some manner are becoming increasingly prevalent both in academic and public discourse. For example, it is common to claim that they spend considerable time and resources to oppose induced abortion, but show little concern regarding the far greater numbers of naturally occurring intrauterine deaths (miscarriages). Critics argue that if abortion opponents took their beliefs about the value of embryos and fetuses seriously, they would invest more time and resources combating these naturally occurring deaths than those caused by induced abortion. The implication is that abortion opponents do not take their beliefs about embryos and fetuses seriously—and so why should anyone else? These “inconsistency arguments”, as we have called them, have considerable intuitive appeal: showing that someone is living inconsistently or holding beliefs that seem prima facie inconsistent seems to many to undermine those beliefs. However, upon closer examination, these arguments become less convincing. In short, we show that the inconsistency arguments we are aware of are severely flawed, and so, if critics wish to continue their criticism, they should abandon inconsistency arguments in favor of other styles of argument. We will proceed in four stages. First, we describe the basic form of inconsistency arguments against abortion opponents. Second, we outline specific instances of the inconsistency argument that have been advanced. Third, we outline specific responses to these arguments, noting ways in which responses also conform to set patterns. Finally, we assess the debate and suggest how it might progress in productive ways.
