Marsilius of Padua is one of the few truly revolutionary figures in the history of political philosophy. The first to propound the separation of Church and State, he is considered the precursor to subsequent political thinkers, from Machiavelli to Marx.

The Marsilian revolution consisted not only in a radical change in the theory of the relations between religion and politics that culminated in the Protestant Reformation and other central developments of the modern era, but, even more importantly, it had an effect on the whole conception of human beings -- their nature, acts, values, and sociopolitical relations.

As Cary J. Nederman writes in the foreword to this new edition, "Marsilius continues to speak to many of the salient issues of modern political life, expressing his doctrines in a language that has resonance and relevance. Whether in addressing the role of citizenship as a buffer between individual and community, or in explicating the foundations of religious toleration, the "Defensor pacis" (and Marsilius' other writings) affords a distinctive theoretical perspective that rivals that of any of the great thinkers of the Western political tradition."

Instilling Ethics casts a fresh light on both the historical sources and the contemporary issues of a major preoccupation of our time: ethics. Norma Thompson has compiled essays from prominent scholars in a wide-range of disciplines to address the problems, pretensions, and positive potentialities of ethical practices today. Instilling Ethics offers a new way of connecting today's ethics to the great ethical sources of the past-- classical, medieval, and early modern--and presents a wise and witty critique of the current practice of 'professional ethics.'

Cosmopolitanism is one of the most venerable intellectual traditions in the history of political philosophy. From the ancient Greek Diogenes' claim to be "a citizen of the world" through to Kant's Enlightenment vision of a world government and even into our own time, the idea of cosmopolitanism has stirred the moral imagination of many throughout history. Arguably the Brexit referendum result and the election of Donald Trump in 2016 marked the first major public repudiation of the transnational, globalizing cosmopolitan ideals that have arguably dominated politics in the liberal democratic West since the end of the Cold War. This volume reconsiders cosmopolitanism and its discontents in the age of Brexit and Trump by bringing together the great thinkers in the history of political philosophy and contemporary reflections on the problems and possibilities of international relations, human rights, multiculturalism, and regnant theories of democracy and the state.
