Are social structures a threat to individual freedom? In this bold and wide-ranging book, Frank Hindriks compellingly argues that they need not be. Combining ontological holism with normative individualism, Hindriks offers an new and innovative framework for understanding social practices, social institutions, and collective agents -- while providing robust guidance for ensuring that these social phenomena do not undermine individual rights. This book is essential for anyone concerned with the nature of social reality or the foundations of political life.
