The book displays a number of virtues. It brings to our attention a series of thinkers influential in their day (both within the academy and without) but now all-too-often ignored. It explores the relationship between their political theories and their political commitments and argues convincingly that we should take their views seriously. As such, Idealist Political Philosophy will be of interest to political theorists (especially the last two chapters), to historians of philosophy (especially the chapters on Caird and Bosanquet), and to historians of mid- to late- nineteenth century politics (especially the chapters on Green and Caird)... For all these reasons, as well as for the clarity of the expression and the ease with which it moves from philosophical to historical to political discussion, the book is valuable and important.
