"Easily the most comprehensive and useful work on American socialism, including its history, theories, and impact on life, culture, and economic and political parties in the United States, is as important a contribution as the essays. Hereafter, students of practically all phases of American life will turn to it for help and guidance."—U.S. Quarterly Book Review. Originally published in 1952. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
