Ronald Dworkin 
Taking Rights Seriously [PDF ebook] 

A landmark work of political and legal philosophy, Ronald Dworkin’s Taking Rights Seriously was acclaimed as a major work on its first publication in 1977 and remains profoundly influential in the 21st century. A forceful statement of liberal principles — championing the legal, moral and political rights of the individual against the state — Dworkin demolishes prevailing utilitarian and legal-positivist approaches to jurisprudence. Developing his own theory of adjudication, he applies this to controversial public issues, from civil disobedience to positive discrimination. Elegantly written and cuttingly insightful, Taking Rights Seriously is one of the most important works of public thought of the last fifty years.
