The Empire of Reason takes a sweep ing look at the origins of the En lightenment and its consequences in America. While new ideas flourished on the Continent during the eighteenth century, “ideas” they remained. Not until strains of this intellectual thought filtered to the colonies were they adopted in practice. In a lively narra tive, historian Henry Steele Commager links European philosophes Banks, Voltaire, Struensee, Diderot, Gustavus III, and Buflbn with their American counterparts Jefferson, Franklin, Rit- tenhouse, and Priestley. He show's that the American Enlightenment wfas not simply derivative ofits European ances try and boldly outlines the thrusts of its development in such documents as The Declaration of Independence and the Constitution.
