Derek Parfit’s On What Matters endorses Kantian Contractualism, the normative theory that everyone ought to follow the rules that everyone could rationally will that everyone accept. This paper explores Parfit’s argument that Kantian Contractualism converges with Rule Consequentialism. A pivotal concept in Parfit’s argument is the concept of impartiality, which he seems to equate agent-neutrality. This paper argues that equating impartiality and agent-neutrality is insufficient, since some agent-neutral considerations are silly and some are not impartial. Perhaps more importantly, there is little realistic prospect of Kantian Contractualism converging with Rule Consequentialism unless the same impartial reasons drive rule selection in the two theories.

This paper’s first section invokes a relevant meta-ethical principle about what a moral theory needs in order to be plausible and superior to its rivals. In subsequent sections, I try to pinpoint exactly what the demandingness objection has been taken to be. I try to explain how the demandingness objection developed in reaction to impartial act-consequentialism’s requirement of beneficence toward strangers. In zeroing in on the demandingness objection, I distinguish it from other, more or less closely related, objections. In particular, I discuss arguments put forward by Bernard Williams concerning integrity, Samuel Scheffler on prerogatives, and Liam Murphy on fairness. The final part of the paper acknowledges some ways in which vagueness bedevils my own rule-consequentialism’s rules about doing good and preventing disasters.
