It is a must-read for those scholars, educators and policy makers interested in the psychology of political and social intolerance." — Jim Sidanius, John Lindsley Professor of Psychology in Memory of William James, Harvard University"In this volume a distinguished group of political scientists and psychologist pay tribute to John Sullivan. Their work builds in important ways on Sullivan’s legacy, updating and extending his seminal insights into political tolerance and ideological reasoning. Perhaps just as importantly, the volume celebrates Sullivan’s role as a valued research colleague and mentor. Its contents are inspiring, informative, and a must-read for political psychologists." — Leonie Huddy, Professor of Political Science, Stony Brook University
