We humans like to believe that we act rationally, but the emotions are a much more important part of experience that most of us think. Richard Firth-Godbehere has put his thoughts on this matter into his book A Human History of Emotion, which analyses and studies the role of human emotions throughout history and in different cultures. The author will talk about how the emotions, in all their complexity and diversity, have modelled the world that we live in over the course of history. This fascinating work of non-fiction weaves together psychology, neuroscience, art, philosophy and religion. In conversation with Alberto de Castro.
