Since Perry Millerpos;'s biography of Jonathan Edwards began a new cycle of study some forty years ago, research into Edwards' life and thought has advanced considerably. No longer is the intellectual giant of colonial America surrounded by the obscurity to which early generations had consigned him. Yale is republishing his works. New secondary studies on Edwards appear regularly. Academics from a range of disciplines - history, American studies, theology, philosophy, and literary criticism - have all made Edwards a focus for serious scholarly attention. As an index to the quickening tempo of research, the total number of dissertations on Edwards increased in geometrical proportion during the last half century, doubling during each of the successive decades since 1940.
