This is a pioneering study of philosophy in the English and Welsh Dissenting academies and Nonconformist theological colleges from the Toleration Act of 1689 to 1920. The author discusses the place of philosophy in the curriculum and the philosophical works published by tutors, professors, and alumni, among them Isaac Watts, Henry Grove, Richard Price, James Martineau, and Robert Mackintosh. It is shown that particular attention was paid to natural theology, moral philosophy, and apologetics, and some of the ideas propounded are of continuing interest. This important book will interest historians of philosophy, of the Church, and of education.
