In this video Steven Pinker introduces his work and discusses his most exciting current projects.

Steven Pinker is one of the world’s leading psychologists, conducting research into language and cognition. His deep studies of language have led him to insights into the way that humans form thoughts and engage with the world. He argues that humans have evolved to share a faculty for language, the same way a spider evolved to spin a web. He spoke to A C Grayling about how we aren't born with ‘blank slates’, to be shaped entirely by our parents and environment, but possess something innate that could arguably be called ‘human nature’.
