Host Marcia Alvar speaks with Peter Gay, Sterling Professor of History, Yale University, and author of The Cultivation of Hatred. Violence is a pervasive force in today’s world, but violence is not a new development. Professor Gay examines the debate in the 19th Century over the proper role of violence and aggression in society. He shows how attitudes in both Europe and the United States were reshaped so that aggression became ritualized in sports, public service and business. While he refuses to compare the era before WWI with the present, he does admit that this is a more violent age.
