Dictionary of the History of Ideas
On behalf of the Directors and Board of Editors of the Journal of the History of Ideas, we are pleased to make available, through digitization, a valuable reference work produced in an earlier generation by a remarkably talented group of scholars. Authors who contributed articles to the Dictionary of the History of Ideas include Isaiah Berlin, George Boas, Herbert Butterfield, Merle Curti, Mircea Eliade, Joan Kelly Gadol, Sidney Hook, Milton Konvitz, Leonard Kreiger, Judith Shklar, Peter N. Stearns, and René Wellek. The editor of the Dictionary was Philip P. Wiener, who was also for many years editor of the Journal of the History of Ideas. Current JHI Editors and Contributing Editors who wrote for the DHI include Robert M. Kingdon, Helen North, Jerrold E. Seigel, and John W. Yolton.
Published in its original edition in 1973-74 and last reprinted in 1977-1980, the Dictionary of the History of Ideas was a culminating work in a tradition that had been energized by the fight against fascism. It was a tradition committed to the pursuit of disinterested scholarship in the academic sphere and to free expression of thought in the political sphere (as in Arnaldo Momigliano’s article “Freedom of Speech in Antiquity”). Among reviewers, F. E. L. Priestley called the Dictionary “monumental,” noting the “impressive list of 254 contributors, drawn from a world-wide range of institutions,” and Roy Porter remarked on its “conceptual richness,” “authoritativeness,” and “originality.” Peter Gay, anticipating another, different style of research, perceptively suggested that “the cultural history of the future toward which our profession is now aiming will have to embrace both thinker and demagogue, poet and peasant, the writer and the reader of newspaper articles.”

More than 520 volumes of Latin, Greek, and English texts are available in a modern and elegant interface, allowing readers to browse, search, bookmark, annotate, and share content with ease.
