Thomas Hill Green (183682) was one of the most influential English thinkers of his time, and he made significant contributions to the development of political liberalism. Much of his career was spent at Balliol College, Oxford: having begun as a student of Benjamin Jowett, he later acted effectively as his second-in-command at the college. Interested for his whole career in social questions, Green supported the temperance movement, the extension of the franchise, and the admission of women to university education. He became Whyte's professor of moral philosophy at Oxford in 1878, and his lectures had a lasting influence on a generation of students. Volume 2, published in 1886, consists of Green's unpublished lecture notes. The Lectures on the Principles of Political Obligation drew criticism upon Nettleship, Green's pupil and editor, for his editorial interventions: the idea of 'common good' was thought to vary significantly here from Green's other writings.
