Thomas Hill Green (April 7, 1836 – March 26, 1882) was an English philosopher, political radical and temperance reformer, and a member of the British idealism movement. Like all the British idealists, Green was influenced by the metaphysical historicism of G.W.F. Hegel. He was one of the thinkers behind the philosophy of social liberalism.

This book contains the political writing of T. H. Green and selections from those of his ethical writings which bear on his political philosophy. Green's best known work, Lectures on the Principles of Political Obligation, is included in full, as are the essay on freedom and the lecture 'Liberal Legislation and Freedom of Contract'. There are also extracts from Green's lectures on the English Revolution and from the Prolegomena to Ethics, and a number of previously unpublished essays and notes. All the texts have been corrected against Green's manuscripts, held in Balliol College. The editors have provided a list of variants, full notes and an introductory essay on the importance of Green's form of revitalised liberalism. The volume will be a valuable sourcebook for students of Green's thought and the history of nineteenth-century liberalism.
