Abstract

This dissertation examines the evolution of David Hume's ethics, focusing on moral judgment, moral motivation and ethical normativity. In chapter one, I argue that previous scholars have missed a crucial distinction between two different sympathetic processes at work in the Treatise. The first sympathetic process, "particular sympathy" is analogous to ordinary empathy and variable in just the way empathy is, but a second, non-variable process, "extensive sympathy" is the source of our moral sentiments. In chapter two, I give an account of Hume's understanding of ethical normativity in the Treatise, arguing that he holds that society, our intimate relationships, and even our ability to be actively concerned with our long-term interests all depend on our adopting extensive sympathy as a standard by which to regulate our character and our passions. The view of moral motivation which then emerges is one on which our moral sentiments play the role of redirecting our natural passions and desires. ;In chapters three and four, I consider the second Enquiry, arguing that what had changed by the time of that work was not primarily the doctrine of Hume's ethics, but his view of the project of writing moral philosophy. In the Treatise, Hume seeks to explain and justify moral standards and judgments, while in the second Enquiry Hume also seeks to inspire people to regulate their lives by those standards and judgments. Only if we are alert to Hume's project in the second Enquiry will we at last resolve debates over whether Hume abandoned the doctrine of sympathy by the time of that work. Similarly, we need to understand the project of that work if we are to understand the section therein on our "interested obligation to virtue," and the appendix to that work called, "A Dialogue." ;In concluding, I place Hume against the map of contemporary ethics, arguing that philosophers with a broad variety of non-Humean and Humean committments have reason to take Hume's ethics seriously, in part because the account of Hume's ethics for which I have argued changes the map of contemporary ethics.
