Defining 'normativity' is itself a normative task, and no clear agreement has been reached on the matter. The normative has often been contrasted with the descriptive; sometimes the normative is thought to be made up of deontic (e.g. 'oughts') and evaluative (e.g. 'good') concepts. 'Normativity' may have at least two senses: first, a nomophoric sense, if one refers to implicit or explicit rules (of various kinds); second, an axiological sense, if one refers to values. Few have defined normativity explicitly; many are interested in the normativity of something else (meaning and content, semantics, aesthetics, moral claims, epistemic norms, context, the law) rather than in normativity itself. When they do, normativity is usually explained (or explained away) with reference to "having reasons".
