Events at the beginning of the twenty-first century have served to demonstrate the truth of the insight at the heart of the recent renewed interest in realist political theory that politics is characterised by inevitable and endemic disagreement and conflict. Yet much contemporary liberal political theory has taken place against the backdrop of an assumed widespread consensus on liberal values and principles. A central theoretical question for our day is therefore whether liberalism is a theory of politics consonant with the modern world or whether it is grounded in untenable theoretical presumptions and foundations.

This monograph offers the first comprehensive overview of the resurgence of interest in realist political theory and develops a unique and urgent defence of liberal politics in realist terms. Through explorations of the work of a diverse range of thinkers, including Bernard Williams, John Rawls, Raymond Geuss, Judith Shklar, John Gray, Carl Schmitt and Max Weber, the author advances a theory of liberal realism that is consistent with the realist emphasis on disagreement and conflict yet still recognizably liberal in its concern for respecting individuals' freedom and constraining political power. The result is a unique contribution to the ongoing debates surrounding realism and an original and timely re-imagining of liberal theory for the twenty-first century. This provocative work will be of interest to students and all concerned with the possibility of realizing liberalism and its moral aspirations in today's world.
