  None of the arguments, on either side, can go quickly or easily.  They all depend, first, on identifying and defending the presuppositions and commitments one takes to be at issue and then, second, on showing that they either cannot, or can, be defended.  What is at stake is, at least, an understanding of what is an important part of most peoples’ lives, but there is potentially a lot more at stake to the extent the presuppositions and commitments people take for granted turn out to be suspect. For then, not only will our understanding of that part of our lives be compromised, our sense that it is important may well disappear as well.
