Journal of the History of Ideas

Since its inception in 1940, the Journal of the History of Ideas has served as a medium for the publication of research in intellectual history that is of common interest to scholars and students in a wide range of fields. It is committed to encouraging diversity in regional coverage, chronological range, and methodological approaches. JHI defines intellectual history expansively and ecumenically, including the histories of philosophy, of literature and the arts, of the natural and social sciences, of religion, and of political thought.
