Dirk Verhofstadt (born 25 August 1955 in Dendermonde) is a Belgian social liberal (Rawlsian) theorist and younger brother of former Belgian Prime Minister and former ALDE European Parliament Leader Guy Verhofstadt. He has a keen interest in political philosophy, and his philosophical outlook is influenced by Karl Popper, John Stuart Mill, Cesare Beccaria, Thomas Paine, Amartya Sen and Martha Nussbaum. Education He graduated in law and press- and communication sciences, and obtained a PhD in moral philosophy at the University of Ghent. He was professor Media and ethics at the University of Ghent until 2020. On 1 July 2010 he obtained the degree of Doctor of Moral Science at the University of Ghent with his doctoral dissertation "Pius XII and the extermination of the Jews. A moral and historical research into the moral responsibility of Pope Pius XII regarding the Final Solution to the Jewish Question." Think tank He is a member of Liberales, an independent think tank within the liberal movement. Its members consider liberalism as a progressive movement supporting individual freedom, justice and human rights. Liberales reacts against what it calls "narrow minded conservatism" related to social economic, ecological and ethical issues supported by "compartmentalized" parties and structures. Writings With his book Het menselijk liberalisme (Human Liberalism), he inspires politicians in Belgian liberal parties as well as in the Dutch parties Volkspartij voor Vrijheid en Democratie and Democraten 66. He defends liberalism against attacks by anti-globalists, by stating that liberalism implies/should imply solidarity and that green politics is not contradictory to liberalism. He wrote the books Pleidooi voor het individualisme (A Plea for Individualism) and De derde feministische golf (The Third Feminist Wave), much of it focusing on Islamic feminism and its impact in Europe. This book contains exclusive interviews with Ayaan Hirsi Ali, Irshad Manji, Naima El Bezaz, , and Yasmine Allas. On 26 September 2008, he released his new book Pius XII and the extermination of the Jews in the Dutch language.
