Thomas Hill Green (1836-82) 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 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. Much of Volume 1, edited by Green’s pupil R. L. Nettleship and published in 1885, consists of Green’s work on David Hume (1711-76). In his essay, ‘Introductions to Hume’s Treatise of Human Nature’ (originally published in 1874), Green gives a detailed critique of Hume’s metaphysical thought.
