João Cardoso Rosas has taught for many years mainly in Political Philosophy and connected disciplines, including in the History of Social and Political Ideas, Contemporary Political Ideologies, Philosophy of Human Rights, and Normative and Applied Ethics. He has supervised Masters’ students, PhD students and post-docs in these fields, and several of them now hold academic positions in Portugal, Cape Verde, Mozambique, Brazil, Spain, and the United Kingdom. His first research interest was the political thought of Karl Popper and other liberal thinkers from the 20th century. Later, he focused on the study of John Rawls’ theory of justice and his libertarian and communitarian critics. He has been particularly interested in questions connected with doctrinal pluralism and the value of stability in democracy as developed by Rawls and others. Over recent years his work has turned to the analysis of ideologies and to the study of the history and philosophy of human rights. He edited and authored several books and he published many articles and chapters of books, most of which in line with these basic interests. He also has been interested in fostering the role of learned societies in consolidating a national community of researchers dealing with politics and political ideas. As a consequence, he has often served in different capacities, including as Chair of the Portuguese Political Science Association and as Chair of the Portuguese Philosophical Society. Furthermore, he has been involved in the creation of several degree programmes at the University of Minho, including the recent MA in Political Philosophy. At UMinho, he also has been active in the creation of research structures. In 2008, he established the Political Theory Group and, in 2017, he founded, with his research fellows in this group, the Centre for Ethics, Politics and Society.
