Abstract

Disputants in the debate regarding whether Hume's argument on induction is descriptive or normative have by and large ignored Hume’s positive argument (that custom is what determines inferences to the unobserved), largely confining themselves to intricate debates within the negative argument (that inferences to the unobserved are not founded on reason). I believe that this is a mistake, for I think Hume’s positive argument to have significant implications for the interpretation of his negative argument. In this paper, I will argue that Hume’s positive and negative arguments should be read as addressing the same issues, whether normative or causal. I will then focus on the Enquiry version of Hume’s positive argument, arguing that it carries a significant normative conclusion: there, Hume argues that custom plays a normative role in justifying our inductive inferences. Given that Hume’s positive argument should be read as addressing the same issues as his negative argument, we should correspondingly read Hume’s negative argument in the Enquiry as having a normative conclusion.
