Jonathan Edwards probably came as near to the old idea of a saint as America ever produced. Self-denying, stern, of an exalted piety, and intensely religious, he lived in a world of his own, and was regarded with no little awe and trembling. That he was a power for good cannot be doubted, and his sermons are still read, where those of his contemporaries have long since been forgotten. Much more important to Princeton, was John Witherspoon, who came to the presidency in 1768, after a distinguished career in Scotland, one of the incidents of which was being taken a prisoner while incautiously watching the battle of Falkirk. He never wholly recovered from the effects of the imprisonment which followed. He brought with him from Scotland a valuable library which he gave to the college, and, finding the college treasury empty, he undertook a vigorous campaign to replenish it, making a tour of New England, and even extending his quest as far as Jamaica and the West Indies. Through his administrative ability and the changes and additions which he made in the course of study, the college received a great impetus. The service to his adopted country by which Witherspoon will be longest remembered, was the course he followed at the beginning of the Revolution. From the first, he took the side of the colonies, and by precept and example, held not only the great body of Presbyterians true to that cause, but also the Scotch and Scotch-Irish, who were naturally Tories by sympathy. He was a member of the Continental Congress, urged ceaselessly the passage of the Declaration of Independence, was one of its signers, and as a member of succeeding Congresses, distinguished himself by his services. After the close of the war, he returned to Princeton and devoted the remainder of his life to its administration. Greatest of the three as an educator was James McCosh. A Scotchman, like Witherspoon, a student of the Universities of Glasgow and Edinburgh, a pupil of Thomas Chalmers, he was ordained to the ministry in 1835, and was a leading spirit in the movement which culminated in the establishment of the Free Church of Scotland. His publications on philosophical subjects brought him the appointment as professor of logic and metaphysics in Queen's College, Belfast, where he remained for sixteen years, drawing to the college a large body of students, and publishing other philosophical works of the first importance. In 1868, he was chosen president of Princeton, and his administration, lasting for nearly a quarter of a century, was remarkably successful. Under him, the student attendance nearly doubled, the teaching staff was more than doubled, and the resources of the college enormously increased. During these years, too, he continued his philosophical work, publishing a series of volumes which are the most noteworthy of their kind ever produced in America.
