We present a criterion for the use of thought experiments as a guide to possibilia that bear on important arguments in philosophy of religion. We propose that the more successful thought experiments are closer to the world in terms of phenomenological realism and the values they are intended to track. This proposal is filled out by comparing thought experiments of life after death by Peter van Inwagen and Dean Zimmerman with an idealist thought experiment. In terms of realism and values (...) we contrast an exemplary thought experiment by Iris Murdoch with one we find problematic by William Irwin. (shrink)

I present and clarify one form of the modal argument for substance dualism, and go on to state and provide defeaters for five of the major arguments raised against the modal argument as a whole. I do not provide an unabridged defence of the modal argument. Instead, I focus on a range of defeaters scattered throughout the literature that are raised against the modal argument. In my view, these have not been gathered in one place and freshly evaluated. Accordingly, my (...) limited purpose is to fill this lacuna. Thus, I present a representative version of the modal argument to set the context for what follows. Next, I clarify and critique the five major objections directed at the modal argument in general.
