Beginning with a survey of the origins and growth of 18th century rationalism, the author explains how the realization of the great philosophers' ideals in Europe was inevitably frustrated by the counterweight of tradition and privilege. He points out that in America there were no such barriers. The principles of the Enlightenment were written into law, crystallised into institutions, and sanctified by use. Although democracy was not absolute (the existence of slavery remained unquestioned), in comparison with Europe, America could justifiably claim to be incorporating the ideals of 'life, liberty and the pursuit of happiness' into the daily lives of her people. The result was the start of an American revolution as significant as the winning of independence and the creation of a nation. This book is a valuable contribution to our understanding of America's past - essential both for a true appreciation of America's European origins and for her subsequent development into the 20th century. "Learning and reason are at the service of a mind whose understanding of democracy gains brilliance and power from a passion for democratic freedom." Arthur Schlesinger Jr.
