 Post-Mackie, philosophers who take up the argument from queerness generally converge on the categoricity or irreducible normativity of reasons as the queer commitment of morality/normativity. Richard Garner (1990) thinks that moral facts are queer because they entail “intrinsic imperativeness”. Joyce variously describes this feature as the “inescapability” (2001: 31), “categoricity” (2001: 37) “practical clout” (2006: 57–58) or “practical oomph” (2006: 60) of moral requirements. In early work (2011), Olson also identifies categorical reasons as the queer commitment of morality, but in later work (2014) says that it is morality’s entailment of irreducibly normative favoring relations that is queer.
