Hans Joas has been a leading figure in German social theory for over thirty years. Currently Ernst Troeltsch Honorary Professor at the Humboldt University of Berlin, his early work was on the thought of George Herbert Mead. This led to his later writings, which centre on defending the legacy of American Pragmatism and illustrating its important implications for social theory. He has been praised for his innovative application of Pragmatic conceptions of creativity to the question of human action and values. Building on the work of Mead, William James, Max Scheler and John Dewey, his theory of the creativity of human action has sought to bridge the divide between an empirical sociological examination of social norms and values and the normative concerns of contemporary philosophy. Polity has published many of his most important works, including The Creativity of Action, The Genesis of Values and War and Modernity.
