Augustine famously claimed that the virtues of pagan Rome were nothing more than splendid vices. This critique reinvented itself as a suspicion of acquired virtue as such, and true Christian virtue has, ever since, been set against a false, hypocritical virtue alleged merely to conceal pride. "Putting On Virtue" reveals how a distrust of learned and habituated virtue shaped both early modern Christian moral reflection and secular forms of ethical thought. Jennifer A. Herdt develops her claims through an argument of broad historical sweep, which brings together the Aristotelian tradition, as taken up by Thomas Aquinas, with the early modern thinkers who shaped modern liberalism. In chapters on Luther, Bunyan, the Jansenists, Mandeville, Hume, Rousseau, and Kant, she argues that efforts to make a radical distinction between true Christian virtue and its tainted imitations actually created an autonomous natural ethics separate from Christianity. This secular value system valorized pride and authenticity, while rendering graced human agency less meaningful. Ultimately, "Putting On Virtue" traces a path from suspicion of virtue to its secular inversion, from confession of dependence to assertion of independence.

This book explores Hume's concern with the destructiveness of religious factions and his efforts to develop, in his moral philosophy, a solution to factional conflict. Sympathy and the related capacity to enter into foreign points of view are crucial to the neutralization of religious zeal and the naturalization of ethics. Jennifer Herdt suggests that Hume's preoccupation with religious faction is the key which reveals the unity of his varied philosophical, aesthetic, political, and historical works.

This interpretation of Hume contests standard views by placing Hume's writings on religion securely within the context of his ethical concerns, and giving due attention to The History of English and The Natural History of Religion. Arguing that important aspects of Hume's writings on religion and moral philosophy can only be understood in light of his worries about the social effects of religion, this text reveals the links between Hume's concept of sympathy in the Treatise and his preoccupation with the destructiveness of religious faction. By tracing these concepts throughout Hume's corpus and setting his discussions of topics ranging from the nature of moral approval to the role of tragedy within the full scope of 18th-century thought, the author is able not only to shed new light on the coherence of Hume's authorship, but also to revise our understanding of the period in which he lived and wrote.

Recent decades have witnessed an enthusiastic retrieval of eudaimonism, according to which the virtuous life is the happy life. But the critique launched by Kant - that eudaimonism is egoistic and distorts the character of duty or obligation - has persisted. Should I develop the virtues because these are the traits I need in order to flourish? Is it facts about my own happiness that determine my obligations to others? In this book, Jennifer Herdt deftly sifts through these debates, showing why we should embrace 'ecstatic' or 'goodness-prior' eudaimonism while rejecting 'welfare-prior' forms of eudaimonism. Grasping the character of ecstatic eudaimonism, she argues, has major implications, overcoming the common assumption of a sharp break between pagan and Christian eudaimonism, as well as of a late medieval or Protestant repudiation of eudaimonism in favor of divine command theory. Agents cannot rightly respond to the goods they encounter unless they respond to them precisely as good, and not merely as a means to promoting their own welfare; in responding well, their agency is thereby necessarily perfected. In conversation with vital strands of contemporary moral philosophy, Herdt goes on to articulate the distinctive character of obligation as a feature of accountability relations among agents. Assuming Responsibility offers a fresh point of departure for theological and philosophical approaches to virtue ethics, moral agency, and the contested relationship between the good and the right.
