What is the author's style in The Concept of Law by H. L. A. Hart?

While there are many analytic philosophers that share Hart's methodological perspective, there are many aspects of Hart's perspective unique to him. For instance, Hart is skeptical about monistic analyses of social and political concepts where important concepts like law are given a single definition. He is sensitive to the indeterminacy involved in language and translates those issues into concerns about determinacy in the law. Finally, he embraces a form of soft legal positivism that is largely unique to him. Hart also criticizes a number of positions, such as Austin's definition of law, legal formalism and rule-skepticism, hard legal positivism and natural law theory and Dworkin's criticisms of his work.
