In this work, the author seeks to expose, compare and criticize David Hume’s moral philosophy from Rosmini’s ethical perspective. He exposes and criticizes, first, ontological and epistemological questions; then, he studies the passions approached from philosophical anthropology. With this examination, the author studies the sentiment as a principle of morality, as well as the concepts of benevolence, justice and social order, making the contrast between both authors. He immediately devoted to ethical concepts of utility, of great significance in Anglo-Saxon philosophy, and of pleasure. Finally, he offers a series of final reflections giving account of the greatest scope of the ethics of Rosmini, who offers a complete moral theory that covers the problem of good, virtue and moral duty.
