  Michael Zimmerman defines possibilism in the simpler, standard sense given above (2006: 153; 2017: 119). However, he also develops and defends (MO)-inspired formulations of possibilism. In his (1996) book, he provides a formulation of what he refers to as “world possibilism” (WP) that invokes the notion of “deontic value” instead of “intrinsic value”, so as to prevent the formulation of possibilism from assuming impartial consequentialism. In his (2006: 166) essay, he defends a prospective version of (WP), where the value in question is the expected value of all the acts an agent can intentionally perform, which he refers to as “adjusted core prospective value”.
