The first six chapters of the book focus on the respective roles of experimental and speculative philosophy in individual seventeenth-century philosophers. They include Francis Bacon, Robert Boyle, Margaret Cavendish, Thomas Hobbes, John Locke and Isaac Newton. The next two chapters deal with the relation between experimental philosophy and religion with a special focus on hypotheses and natural religion. The penultimate chapter takes a broader European perspective and examines the paucity of concerns with religion among Italian natural philosophers of the period. Finally, the concluding chapter draws all these individuals and themes together to provide a critical appraisal of recent scholarship on experimental philosophy. This book is the first collection of essays on the subject of early modern experimental philosophy. It will appeal to scholars and students of early modern philosophy, science and religion.
