The British idealists made significant and lasting contributions to the social and political thought of the nineteenth century. They contributed to the evolution debate in insisting that the social organism could not be understood in naturalistic terms, but instead had to be conceived as an evolving spiritual unity. In this respect the British idealists developed a distinctive view of the state constitutive of the individual and they are commonly acknowledged as the forerunners of modern communitarian theory. Furthermore the idealists contributed to the major debates of their day, including evolution, democracy, the role of the state, education and international relations. In his introduction, David Boucher develops the themes illustrated in the writings of the British idealists. This volume also contains biographies of the British idealists which incorporate their principal works.
