Abstract

This paper provides a reception history of Book Two of the Treatise-Of the passions-as well as an attempt to reconcile Hume's ambitions to systematicity in Book Two with the distracted and distracting nature of the text. We currently have, I think, a good sense of the philosophical importance of Book Two within Hume's science of human nature. Yet we have not made much progress on understanding Book Two on its own terms, and especially why Book Two so often seems on the verge of falling into an explanatory heap. I aim to rectify this situation by giving a reading of Book Two that makes sense of the philosophical importance of Hume's system of the passions, yet also explains why he encounters so many difficulties in setting out his system; such that he is often forced to stretch his explanations to the very edge of the credible. I contend that Hume's system of the passions is best viewed as an unstable explanatory compound, one that progressively dissolves as Hume's explanatory intentions become increasingly ambitious.
