The better angels of our nature : why violence has declined
Steven Pinker (Author)
This volume argues that violence in the world has declined both in the long run and in the short, and suggests explanations why this has happened. The author maintains that the key to explaining the decline of violence is to understand the "inner demons" that incline us toward violence and the "better angels" that steer us away. Thanks to the spread of government, literacy, trade, and cosmopolitanism, we increasingly control our impulses, empathize with others, debunk toxic ideologies, and deploy our powers of reason to reduce the temptations of violence. The book is divided into 2 parts. The first part is an effort to describe a broad sweep of human history from prehistoric societies to the present, arguing for a progressive though intermittent decline in violence in human societies. The second part is an effort to understand the underpinnings of the decline in violence in terms of human psychological processes
