AN ENQUIRY CONCERNING THE PRINCIPLES OF MORALS

An Enquiry Concerning the Principles of Morals is David Hume's mature statement on ethics, sympathy, utility, virtue, and the foundations of moral judgement. First published in 1751, the work revises and sharpens Hume's earlier moral philosophy from A Treatise of Human Nature, asking not whether morality rests on abstract reason alone, but how human beings actually approve, condemn, admire, and blame. Hume argues that moral distinctions arise from human sentiment, social feeling, usefulness, and the qualities that make character beneficial or agreeable to oneself and others.The book is central to Enlightenment moral philosophy because it treats ethics as part of a broader "science of man": an inquiry into human nature, social life, custom, sympathy, and practical judgement. Hume's discussion of justice, benevolence, utility, merit, obligation, and the artificial and natural virtues helped shape later debates in ethics, utilitarian thought, moral psychology, political philosophy, and Scottish Enlightenment studies. For readers of classic philosophy, moral philosophy, empiricism, secular ethics, and eighteenth-century thought, An Enquiry Concerning the Principles of Morals remains one of Hume's most accessible and important works. Liberty Fund describes Hume's two Enquiries as among his most important works in moral philosophy, epistemology, and psychology, revising the earlier Treatise into the project Hume understood as his "science of man."
