Popularizing Moral Philosophy by Acting as a Moral Expert

Abstract This paper is concerned with the ethics of popularizing moral philosophy. In particular, it addresses the question of whether ethicists engaged in public debates should restrict themselves to acting as impartial informants or moderators rather than advocates of their own moral opinions. I dismiss the idea that being an impartial servant to moral debates is the default or even the only defensible way to publicly exercise ethical expertise and thus, to popularize moral philosophy. Using a case example from the public debate about the human use of nonhuman animals, I highlight the benefits and risks of endorsing an advocate’s and a teacher’s or moderator’s role, respectively. I argue for a general requirement of judgment transparency which entails that the publicly engaged philosopher ought to be clear and consistent about the type of role she takes on, her publicly advanced opinions generally ought to be her professional ones and that she ought to flag her private opinions. I finally show that, despite general concerns about conflicts of interest, exercising ethical expertise and engaging in advocacy, i.e., acting as if one were a moral expert, are not incompatible modes of public engagement for the moral philosopher.
