When earlier versions of this paper were presented (initially in 2003), the author discovered, to his amazement, that audiences varied quite consistently in their receptiveness depending on whether the central example was abortion or vegetarianism. The hostility to philosophical arguments raising a problem specifically with abortion was palpable. Perhaps this is due to intrinsic features of the arguments, or perhaps it is related to the lack of cognitive diversity in many philosophy departments.
