In this lesson, you will be introduced to legal positivism under H. L. A. Hart and Ronald Dworkin, who were both influential in its development as a school of thought. Hart, specifically, is a prominent figure in legal positivism, while Dworkin, an interpretivist, positions himself in between positivism and naturalism. We will also explore legal positivism under Hart, positivism under Dworkin, and the reintroduction of formalism versus realism.
