Why was Leibniz so fascinated by Chinese philosophy and culture? What specific forms did his interest take? How did his interest compare with the relative indifference of his philosophical contemporaries and near-contemporaries such as Spinoza and Locke? In this highly original book, Franklin Perkins examines Leibniz's voluminous writings on the subject and suggests that his interest was founded in his own philosophy: the nature of his metaphysical and theological views required him to take Chinese thought seriously.
