So I finally did, starting with one of his more famous articles, “Authority, Law, and Morality”. In this article, he presents his famous argument for legal-political positivism. The argument is based on a particular conception of authority, and a particular view about the relationship between legal directives and that kind of authority. It is one of the most widely-discussed and important arguments in political and legal philosophy. In this post, and the next, I want to briefly exposit and comment on it. I haven't seen this done well anywhere else on the web so it might prove useful to somebody other than myself.
