When Everyone Knows That Everyone Knows

'One of the most insightful books I've read about what makes us human and how we understand each other' Bill Gates

Steven Pinker, one of the world's greatest thinkers and bestselling author of Enlightenment Now, The Better Angels of Our Nature and The Language Instinct, reveals the power and perils of thinking alike

As a cognitive scientist, the ultimate subject of Steven Pinker's fascination is how we think about each other's thoughts, ad infinitum. It sounds impossible, but Steven Pinker shows that we do it all the time. This awareness, which we experience as something that is public or out there, is called common knowledge, and it has a momentous impact on our social, political, and economic lives.
