What does it mean to be fair? Why do we feel unfairness so strongly? What has happened to us today that we spend more time condemning each other's views than giving each other a fair hearing? The idea of fairness is one of the most commonly-expressed concepts, not only in English but many other languages, yet nobody ever stops to think what it really means. We all simply take the word 'fair' for granted. In this polemical guide to fairness, Ben Fenton explains the meaning of the word, how it fits into our genetic make-up within the deepest recesses of our brains and why we need our innate sense of fair play now more than ever. Fenton explores the idea that the unconscious procedure that humans go through in deciding fairness is the vital balancing act between competition and cooperation, the two driving forces that have made us the super-species of Planet Earth. He describes the neurology, anthropology, psychology, history and future of fairness and looks at how it affects our lives through politics, law, sex, religion, race, sport, business and even war. As a reporter of thirty years' experience, Fenton brings all his skills to bear in a lively and challenging description of the profound inner meaning of a throwaway phrase and why it matters so much to every single person in the world to seek To Be Fair.
