Public policy debates often turn on how to get things done once we know our policy objectives. But how do we make appropriate progress when people disagree about what those objectives might be? In this volume, a team of world-renowned scholars introduce and explore the power of philosophy as a tool for understanding public policy controversies. Each chapter uses the tools and concepts of philosophy to frame an assessment of what is at stake in an enduring and recent policy debate. Organised thematically, the volume addresses issues such as disability policies, parenting, immigration, political apologies, criminal punishment, data gathering, and more. Drawing on the resources of ethical theory, social philosophy, and political theory in a highly accessible way, the book is ideal for students and scholars in both philosophy and public policy.
