Stuff of Thought

Why do so many swear words involve topics like sex, bodily functions or the divine? Why do some children's names thrive while others fall out of favour? Why do we threaten and bribe and seduce in such elaborate, often comical ways? How can a choice of metaphor damn a politician or start a war? And why do we rarely say what we actually mean? Language, as Steven Pinker shows, is at the heart of our lives, and through the way we use it - whether to inform, persuade, entertain or manipulate - we can glimpse the very essence of what makes us human.
