 It is now common to distinguish thick ethical concepts—like courage—from thin ethical concepts—like ought or good (for an introduction to thick ethical concepts, see Roberts 2017). Courage seems like an ethical concept: we expect each other to treat courage as a virtue and not a vice. However, competent use of thick ethical concepts seems to require recognition that only certain sorts of grounds make an ascription of such a concept apt. To adapt Monty Python’s example, it seems conceptually inapt to say that Sir Robin was courageous in light of running away from battle, even if we think that is what he ought to have done.
