This book offers a new phenomenological interpretation of T.H. Green's (1836-1882) philosophy and political theory. By analyzing his theory of human practice, the moral idea, the common good, freedom and human rights, the book demonstrates that Green joins the same tradition as Kantian and Husserlian transcendentalism. The book offers a reconstruction of Green's idealism and demonstrates its potential to address contemporary debates on the nature of moral agency, positive and negative freedom and on justifying human rights.
