In this book, David Owens argues that being bound by a convention can also be valuable for its own sake. People need meaning in their lives and conventions infuse acts and attitudes with normative significance, rendering them right or wrong, appropriate or inappropriate, required or forbidden. Such rules bind us not just in virtue of their usefulness but also because their absence would impoverish our social world. Appreciating this point is essential to a proper understanding of our cultures of neighbourliness and hospitality, family structures, systems of property rights, conventions around speech, the norms governing how we deport ourselves in public, and even the rules of a game.
