Between Realism and Relativism: Moral Certainty as a Third Option

This paper is an attempt to lay out a meta‐ethical position that is inspired by the framework of Wittgenstein's later philosophy. To achieve this goal, this paper is divided into two parts. First, I explore recent attempts to tie Wittgenstein's epistemology in On Certainty to moral epistemology. I argue that there can be a meaningful parallel drawn between the epistemic certainties discussed in On Certainty and what I consider to be moral certainties. These moral certainties are unjustified fundamental moral attitudes that underlie our moral practices. Then, I show how the debate over moral certainty has branched into two directions. One direction presents the concept of moral certainty as a naturalistic concept. On this reading, moral certainties transcend time and place since they are rooted in our natural tendencies to act or not act in certain ways. The other direction presents moral certainty as a distinctly relativistic concept. On this reading, we have our moral certainties because we belong to communities that agree on these certainties. In the second section, I argue that we have both natural, universal certainties and localized, relative certainties. I also argue that our localized certainties are constrained by non‐moral facts about ourselves and about the world. To make this argument, I rely on Wittgenstein's concept of “general facts of nature.” The result of the paper is a meta‐ethical position that can be located in between moral relativism and moral realism.
