Abstract
I defend normative realism—the claim that there are mind-independent, absolute normative facts—mostly by arguing against its rivals. Against mind-dependent theories of normativity, I argue that at least one highly influential version of such a view, Lewis's dispositional theory of value, is subject to at least three severe problems: the problem of the implausible contingency of value, the problem of ideal conditions, and the problem of lack of convergence. Against relativistic conceptions of normativity, I argue that either they fail to evade a commitment to absolute normative truths, or they fail to distinguish themselves from Nihilism. Finally, against Nihilism, I argue that it is not a coherent option at least for the normative domain of rationality, since facts about rationality are presupposed by any judgment, including any judgment meant to express a skepticism about facts about rationality.
