Book excerpt: This pioneering work is the basic and largely unmatched study of the single transatlantic community of thought shared by nineteenth century British and Canadian Liberals and American Democrats. The result of more than ten years of comparative research, The Transatlantic Persuasion explores the roots of those ideas that comprise a coherent Liberal-Democratic worldview: ideas about society, human relations, the economy, equality, liberty, the ethnocultural dimension of life, the proper role and nature of government and the world community.
