Politics Without Vision
Richard Ned Lebow, James O. Freedman Presidential Professor of Government Emeritus and Professor of International Political Theory at the Department of War Studies, King’s College London

I heartily recommend Tracy Strong, Politics Without Vision: Thinking Without a Bannister in the Twentieth Century (Chicago: University of Chicago Press, 2012). The 20th century rejected all certitudes and foundations for ethics and politics. Strong shows how Nietzsche, Weber, Freud, and other thinkers struggled to make sense of morality and politics in such a world.
