Response to Van Inwagen and Welty
In response to my critics, I argue that Peter van Inwagen, despite his protestations, is an advocate of an indispensability argument for Platonism. What remains to be shown by van Inwagen is that his version of the argument overcomes his own presumption against Platonism and survives defeat by besting every anti-Platonist alternative. While acknowledging Greg Welty’s helpful responses to my worries about divine conceptualism as a realist alternative to Platonism, I express ongoing reservations about some of those responses.
