Moral Tribes: The Tragedy of Common-Sense Morality

In which situations should we consider and in which should we simply trust our instincts? Our brains were designed for tribal life, programmed to live harmoniously with a group of individuals who share the same beliefs, habits, and values, and to fight against those who don't belong. However, as the world shrinks, the moral lines that separate us become more pronounced and more intriguing, resulting in epic clashes, and we wonder when—if ever—we will reach a consensus. In this book, Greene unravels the deep structure of moral problems, establishing the differences between the modern conflicts we face and those our brains have been conditioned to solve. Drawing on philosophical dilemmas and psychological experiments, the author shows how the right kind of reflection can help us progress, seeking to transform this new understanding into a universal moral philosophy that members of all human tribes can share.
