In the thesis, I provide a defense of the moral error theory. In the first section, I solve the formulation problem, which is the puzzle related to properly formulating the moral error theory without self-defeat. In the second section, I defend the claim that moral concepts commit their users to irreducibly normative reasons. Finally, in the third and last section, I defend the reduction argument against new criticisms and conclude that there are no irreducibly normative reasons.
