This volume completes Isabel Rivers' widely-acclaimed exploration of the relationship between religion and ethics from the mid-seventeenth to the later eighteenth centuries. She investigates what happened when attempts were made to separate ethics from religion, and to locate the foundation of morals in the constitution of human nature. Her book pays close attention to the movement of ideas through the British Isles, and demonstrates the enormous influence of Shaftesbury's moral thought. Meticulously researched and accessibly written, this study makes a vital contribution to our understanding of eighteenth-century thought.
