This paper has two aims. First, I critically discuss Daniel Whiting’s :2191–2208, 2018) recent proposal that a reason to ϕ is evidence of a respect in which it is right to ϕ. I raise two objections against this view: it is subject to a modified version of Eva Schmidt’s :708–718, 2018) counterexample against the influential account of reasons in terms of evidence and ‘ought’, and—setting aside judgments about specific cases—, it is also in an important sense uninformative. Interestingly, it turns (...) out that this last objection cannot be helpfully understood in terms of circularity. This leads to a more general question about the criteria of adequacy for reductive accounts of reasons: In what sense, if any, should such accounts be informative? The second aim of this paper is to clarify one such sense, which is suggested by reflection on Whiting’s proposal. In particular, I argue that successful reductive accounts naturalize the contributory—by which I mean, roughly, that they explain the specifically contributory nature of reasons in fully non-normative terms. Moreover, I explain how views that fail this criterion are unable to meet certain key explanatory desiderata for reductive accounts of reasons. After broaching some of the wider implications for the project of understanding the notion of a reason in other terms, I conclude that the notion of naturalizing the contributory is a helpful notion for structuring the debate over reductive accounts of reasons.
