Gerald Gaus was one of the leading liberal theorists of the late twentieth and early twenty-first centuries. He developed a pioneering defence of the liberal order based on its unique capacity to handle diversity and disagreement, and he presses the liberal tradition towards a principled openness to pluralism and diversity. This book brings together Gaus's most seminal and creative essays in a single volume for the first time. It also covers a broad span of his career, including essays published shortly before his death, and topics including reasonable pluralism, moral rights, public reason, and the redistributive state. The volume makes accessible the work of one of the most important recent liberal theorists. Many readers will find it of value, especially those in political philosophy, political science, and economics.
