Erich Fromm was one of the most influential and creative public intellectuals of the twentieth century. He was a mentor to David Riesman and an inspiration for the New Left. As the rise of global right-wing populism and Trumpism creates new interest in the kind of psycho-social writing and popular sociology that Fromm pioneered in the 1930s, this timely book tells the story of the rise, fall and contemporary revival of Fromm s theories.Drawing from empirical work, this is an invaluable contribution to popular debates about current politics, the sociology of ideas and the prospect of a truly global public sociology.
