 Green published a fairly small number of articles, reviews, and pamphlets during his lifetime. He wrote the influential critical commentary on Hume’s Treatise of Human Nature, which was part of The Philosophical Works of David Hume, that he and T.H. Grose edited and published in 1874. In addition, he wrote a three-part article “Can There Be a Natural Science of Man?” published in Mind in 1882, the year he died. These two works reflect metaphysical and epistemological themes that were incorporated into Book I of Green’s Prolegomena to Ethics, published posthumously in 1883. In addition, Green’s “Lecture on Liberal Legislation and the Freedom of Contract” was published in 1881 (Works III). Green’s other main philosophical works were published posthumously. This includes Green’s most important work, the Prolegomena to Ethics. The Prolegomena was substantially completed prior to Green’s death, except for 20–30 pages which he had hoped to add. At Green’s instructions, A.C. Bradley oversaw the Prolegomena’s publication in  1883.[2]  Other important posthumous publications include his essay “On the Different Senses of ‘Freedom’ as Applied to Will and to the Moral Progress of Man,” his Lectures on the Philosophy of Kant, and his Lectures on the Principles of Political Obligation (all in Works II).
