Moral Demandingness and Modal Demandingness

My aim is to propose a better way to understand moral demandingness: a counterfactual view that requires us to consider the demands that moral theories make across other possible worlds. Seemingly, the demandingness of any moral theory or principle should be evaluated in terms of that theory’s general demandingness. This, in turn, implies that we ought to be concerned about the possible demandingness of moral theories and not just about how demanding they actually are. This counterfactual view might also have some surprising implications about how demanding commonsense morality really is. After all, commonsense morality might be extremely demanding in many possible worlds. This consideration, in turn, risks undermining the commonsense moral theorist's ability to make purely cost-based demandingness objections against consequentialism, giving us strong reasons to worry about the purely cost-based demandingness objection’s viability in general.
