Enquiry Concerning the Principles of Morals

Judging it to be "of all my writings incomparably the best, " Hume accurately assessed this groundbreaking classic, which continues to influence philosophical thinking on ethics to this day through the force of its ideas and its clarity of expression. Among the many insights that Hume expounds in this work is that morality is grounded in feelings, not in knowledge. Based on moral sentiment, people naturally value agreeable qualities and shun disagreeable ones. On closer analysis, Hume concludes that the feeling of agreeableness comes from an innate perception of the utility of a particular quality or person to one's self. Anticipating later utilitarian philosophy, he maintains that the virtues that are most highly esteemed are those that have the greatest usefulness to most people. Justice, for example, is greatly prized because it ideally ensures to everyone a fair share of happiness and security. Hume puts special emphasis on altruism, which he says is rooted in the natural feeling that each of us has for our fellow human beings. When surrounded by people in enjoyable circumstances, we tend also to feel the same enjoyment, and when learning of tragedy, even among people on the other side of the world, we tend to feel sad. Out of such natural sympathy and our general moral sentiments, moral distinctions between good and bad arise, and we are motivated to direct our actions toward ideal goals, not only for ourselves but especially for others. In many ways, Hume's thinking about ethics was considered radical in its day. His empirical method of interpreting morality as an outgrowth of innate, human emotions helped to steer later philosophy away from the transcendentalist notions of ethicsthat had earlier prevailed.
