Abstract

Reasons-first theorists claim that facts about reasons for attitudes are normatively primitive, and that all other normative facts ultimately reduce to facts about reasons. According to their view, for example, the fact that something is good ultimately reduces to facts about reasons to favour it. I argue that these theories face a challenging dilemma due to the normativity of arational lifeforms, for instance the fact that water is good for plants. If all normative facts are, ultimately, facts about reasons for attitudes, then reasons-first theorists must either (a) show that these facts do reduce to facts about reasons, or (b) concede that they do not and, instead, show that this is not a problem for their view. Both options, however, are riddled with difficulties—or so I will try to argue.
