This book includes revisions of papers originally presented at the inaugural conference of the International Society for MacIntyrean Philosophy, on the theme of Alasdair MacIntyre’s Revolutionary Aristotelianism: Ethics, Resistance and Utopia, hosted by the Human Rights and Social Justice Research Institute at London Metropolitan University. The papers selected are by fifteen leading international philosophers and political theorists. Writing from a variety of perspectives, they address MacIntyre’s accounts of Aristotelianism, Thomism and Marxism, his virtue ethics and metaethics, the development of his philosophical project, and his critiques of managerialism, capitalism and liberalism. The book concludes with an extensive response by MacIntyre, in which he clarifies his past arguments, his present position, and his relation to rival theories of moral, political and social practice.
