Current discussions of liberalism in world affairs tend to take a shortsighted view of the historical antecedents of the school of thought. Most jump directly from Kant to Wilson with little pause in between. In this book, Clinton has selected three thinkers to exemplify developments in the liberal world, all of whom were figures of real consequence in their own time, yet altogether different in temperament and subsequent fashion. Clinton shows how their interests and concerns, both complementary and divergent, make sense of nineteenth-century liberalism without turning it into the rigid doctrine it has never been - and never can be. By using their published works, speeches, and other correspondences, Clinton explores the way they applied their general insights on politics and society to the particular conditions of the international life. In so doing he provides a comparative study of the variants on a distinctively ''liberal'' approach to international relations of this period, which may hold lessons for our own time.
