 Pending a successful definition, the priority monist may still play defense in two main (and connected) ways. First, she may argue that both Lewis’s and Rosen’s conceptions of intrinsicness are independently known to be problematic (c.f. Weatherson and Marshall 2012: §3), so that it is not such a big deal if priority monism is incompatible with either conception. Secondly, she may turn the tables, and—following Trogdon (2009)—maintain that any conflict between priority monism and a proposed definition of intrinsicness reflects badly on the proposed definition of intrinsicness. As Trogdon (2009: 137) explains, “For me, pluralism and monism are each epistemic possibilities, so it is a virtue of an account of intrinsicality to be neutral between them.”
