He was editor of the European Journal of International Relations and has served as a member of the editorial boards for several leading European, American and Asian journals.

• Foreword; 1. Constructivism and the practices of (international) politics: the case for a humean approach; 2. Constituting; 3. Changing; 4. Showing; 5. Guiding; 6. Sanctioning; 7. Punishing; 8. Remembering and forgetting; 9. Knowing and doubting; 10. Acting; 11. Judging and communicating.

'This is the most compelling defence of a 'thick' constructivist approach to social, political, legal and international theory since the classic works by Kratochwil himself and Nicholas Onuf in the 1980s - but it is much more than that. Complex, challenging, very demanding but immensely rewarding, Friedrich Kratochwil's account of Praxis illuminates all aspects of an approach to social life that focuses on action, norms and ideas. This is a book that demands to be read and reread, a genuine classic.' Chris Brown, Emeritus Professor of International Relations, London School of Economics and Political Science
