`Recommended for all students, undergraduate and graduate level.' Choice `All readers should gain something from this book ... the author's identification of problems besetting the category of political obligation is always refreshing and sensible.' Political Studies 'this admirable reflection achieves fresh perspectives on much-discussed issues and effects a distinctive amalgamation among well-rehearsed theories of authority. Green's incisive critiques of received formulations and bold if occasionally adventuresome proposals enliven a slightly tired set of topics.' Canadian Philosophical Review, Vol.9, No.10 & 11, Oct/Nov '89 'this admirable reflection achieves fresh perspectives on much-discussed issues' Richard E. Flathman, The Johns Hopkins University, Canadian Philosophical Reviews Oct-Nov '89)
