Attitudes and the Normativity of Fittingness

What is the structure of normative reality? According to X First, normativity has a monistic foundationalist structure: there is a unique normatively basic property in terms of which all the other normative properties are analysed. The main aim of this paper is to defend the view that fittingness—the property that an attitude has when it gets things right with respect to its object, as when you admire the admirable or desire the desirable—is first, or perhaps joint first. I will focus in particular on the questions whether and why fittingness is normative.
