On the agent-relativity of 'ought'.

In the standard theory of deontic modals, 'ought' is understood as expressing a propositional operator. However, this view has been called into question by Almotahari and Rabern's puzzle about deontic 'ought', according to which the ethical principle that one ought to be wronged by another person rather than wrong them is intuitively coherent but the standard theory makes it incoherent. In this paper, I take up Almotahari and Rabern's challenge and offer a refinement of the standard theory to handle the puzzle. I propose that 'ought' is evaluated relative to contextual parameters (e.g. Kratzer's conversational backgrounds, Finlay and Snedegar's alternative sets) and those contextual parameters are sensitive to agents as well as possible worlds.
