Abstract

Hume argues that whenever we seem to be motivated by reason, there are unnoticed calm passions that play this role instead, a move that is often criticised asad hoc(e. g. Stroud 1977 and Cohon 2008). In response, some commentators propose a conceptual rather than empirical reading of Hume’s conativist thesis, either as a departure from Hume (Stroud 1977), or as an interpretation or rational reconstruction (Bricke 1996). I argue that conceptual accounts face a dilemma: either they render the conativist thesis trivial, or they violate Hume’s thesis that ‘a priori, any thing may produce any thing’ (THN1.4.5.30). I defend an empirical construal of Hume’s conativist thesis. I provide two theoretical frameworks within which Hume’s appeal to the calm passions may be justified: first, by the framework of theoretical virtues, and secondly, by lights of his own “rules by which to judge of causes and effects” (THN1.3.15).
