Abstract: This anthology presents, for the first time, full texts of the twenty most important works of American legal thought since 1890. Drawing on a course the editors teach at Harvard Law School, the book traces the rise and evolution of a distinctly American form of legal reasoning. These are the articles that have made these authors--from Oliver Wendell Holmes, Jr., to Ronald Coase, from Ronald Dworkin to Catherine MacKinnon--among the most recognized names in American legal history.
