Richard Cumberland is one of the seventeenth century's most interesting political theorists. His masterpiece, the De legibus naturae(1672), has rarely been examined on its own terms, but by tracing the political, religiousand intellectual circumstances of the composition of this puzzling work, and showing its importance as a critique of Thomas Hobbes, author of the Leviathan, Dr Parkin demonstrates how Cumberland created a new political andethical theory which absorbed and neutralised many of Hobbes's insights. He also examines the science of the Royal Society as a basis for Cumberland's natural law theory and its influence on such thinkers as Samuel Pufendorf and John Locke. Overall, the book provides an important new perspective on the interaction of science, religion and politics in Restoration England.
