Hume published Book III (“Of Morals”) of A Treatise of Human Nature, presenting an ethics grounded in human feelings rather than pure reason. He argued that we approve or blame character traits through sentiments shaped by human psychology and social life. This set the foundation for his later account of virtue as what people naturally esteem in persons.
Hume published the first volume of Essays, Moral and Political, shifting from the Treatise’s technical style to shorter pieces aimed at educated readers. This helped him test and communicate ideas about character, social behavior, and moral judgment in a more accessible form. The essays also strengthened the link between virtue talk and real social practices.
A second volume of Essays, Moral and Political appeared, continuing Hume’s project of explaining moral life through observation of human motives and institutions. Across the essay format, Hume connected virtues to the needs of social cooperation and stable government. This work helped prepare the later, more systematic statement of his moral philosophy.
Hume published An Enquiry concerning Human Understanding, a shorter work meant to restate key ideas more clearly than the Treatise. While mainly about knowledge, it also sharpened the broader “science of man” approach behind his ethics: human understanding and human passions must be studied together. This framework supported his view that moral evaluation grows out of human nature, not abstract rational proofs.
Hume added and revised essays in a new edition, including influential political pieces such as “Of the Original Contract” and “Of Passive Obedience.” These writings pushed a virtue-centered, practice-focused view of political legitimacy, emphasizing how stable rules and character traits support social order. They also reinforced his broader claim that moral and civic norms work through shared human sentiments and expectations.
Hume published An Enquiry concerning the Principles of Morals, his most focused presentation of ethics. He argued that moral distinctions rest on sentiments of approval and disapproval, and he defined virtues as qualities that are useful or agreeable to oneself or others. The book also distinguished “natural” virtues from “artificial” virtues like justice, which depend on social conventions needed for cooperation.
Hume published Political Discourses, essays on commerce, money, and public policy that also shaped his moral outlook. These writings treated good institutions and stable expectations as supports for social trust and cooperative behavior—conditions under which virtues can be rewarded and vices discouraged. In this way, Hume’s virtue talk remained tied to real human incentives and social outcomes.
Hume took the post of Keeper (librarian) of the Library of the Faculty of Advocates in Edinburgh. The position gave him access to extensive collections and steady income, supporting his research and writing during a productive period. His work in Edinburgh’s intellectual world helped connect moral philosophy to history, politics, and culture.
Hume published Four Dissertations, including “A Dissertation on the Passions” and “Of the Standard of Taste.” These essays extended his moral psychology: to understand virtue and vice, we must understand how emotions work and how people form shared standards in social life. The collection also applied his naturalistic method to religion and aesthetics, showing how sentiments shape multiple areas of human judgment.
Hume issued Essays and Treatises on Several Subjects, bringing together major essays and related works in a more unified collection. This consolidation helped fix how readers encountered his moral and political ideas, with virtue and character discussed across ethics, politics, and criticism. It supported the view that moral philosophy should describe how people actually evaluate character in everyday life.
Although mostly written earlier and kept unpublished during his lifetime, Hume completed final revisions to Dialogues Concerning Natural Religion shortly before he died. The work debates the limits of arguments about God and highlights the role of human temperament and sentiment in religious belief. This reinforced Hume’s broader view that many “moralized” outlooks are rooted in human psychology rather than demonstrative reasoning.
Hume died in Edinburgh on 25 August 1776, leaving a moral philosophy centered on how people actually praise and blame character. His moral sentimentalism treated virtues as traits that people value because they are useful or agreeable in human life, and because sympathy helps spread that approval beyond self-interest. This approach became a major early modern alternative to reason-centered and rule-centered moral theories, influencing later debates about virtue, emotion, and social norms.
