"In Humanity: An Emotional History Walton examines the history of each of our core emotions - fear, anger, disgust, sadness, jealousy, contempt, shame, embarrassment, surprise and happiness - in turn. For Walton, love and hate (between which there is famously only a thin line), are fundamental feelings that inveigle their way into all the other emotions. And he shows convincingly that without these emotions, there would be no human history."--Jacket.
