This volume records the proceedings of the Centennial Colloquium at Boston . The theme of the conference, held early in 1963, is ""Liberation and Limita i.e., can man simultaneously control the explosion in knowledge and maintain society resting upon individual judgment. The consensus, wistful or wishful, mative. Among the eminent scholars whose addresses are reproduced here are Jones (""Modern Scholarship and the Data of Greatness""), Peter A. Bertocci Co-responsive Community""), Lynn T. White, Jr. (""The Changing Middle Ages""), and Ward (""The Unity of the Free World""). There is much material for reflection in work, both on man and on his work; however, there is also much of that inbred humor, not always without malice, which one normally expects to find only in sections of the professional journals. On the whole, the book will appeal , from whom it originated and to whom it was addressed.
