The depth of Mr. Beecher's religious nature prevented this enthusiasm for material science from degenerating into dry materialism. He was a Calvinist in the earnestness of his intense need of the highest and deepest in religion. In his sophomore year there was a revival of religion in college, in which his mind was powerfully excited. He reviewed the almost childish experiences under which he had joined the church, as possibly deceptive, and tried and disciplined himself by those profound tests with which the Edwardean theology had filled the minds of New England. A blank despair was the result. He applied to Dr. Humphrey, who simply told him that his present feelings were a work of the spirit, and with which he dared not interfere. After days of almost hopeless prayer, there came suddenly into his mind an ineffable and overpowering perception of the Divine love, which seemed to him like a revelation. It dispelled all doubts, all fears; he became buoyant and triumphant, and that buoyancy has been marked in his religious teachings ever since. Mr. Beecher's doctrine upon the subject is that the truths of the Divine nature are undiscoverable by the mere logical faculties, that they are the province of a still higher class of faculties which belong to human nature, the faculties of _spiritual intuition_; that it is through these _spiritual intuitions_ that the Holy Spirit of God communes with man, and directs through them the movements of the lower faculties. In full faith in the dependence of man on the Holy Spirit for these spiritual intuitions, he holds substantially the same ground with Jonathan Edwards, though he believes that Divine influence to be far more widely, constantly and fully given to the children of men than did that old divine. During his two last college years, Mr. Beecher, like other members of his class, taught rural schools during the long winter vacations. In this way he raised funds of his own to buy that peculiar library which his tastes and studies caused him to accumulate about him. In both these places he performed the work of a religious teacher, preaching and exhorting regularly in stated meetings, giving temperance lectures, or doing any reformatory work that came to hand. In the controversy then arising through the land in relation to slavery, Mr. Beecher from the first took the ground and was willing to bear the name of an abolitionist. It was a part of the heroic element of his nature always to stand for the weak, and he naturally inclined to take that stand in a battle where the few were at odds against the many. In 1832 Dr. Lyman Beecher moved to Cincinnati, two years before the completion of Henry's college course. He graduated in 1834, and went out to Cincinnati. The abolition excitement at Lane Seminary had just ended, by the departure of a whole class of some thirty students, with Theodore Weld at their head.
