When at Cambridge, his acquaintance with Mr. Frend led him to study the philosophy of Hartley, and he became one of his disciples. Perhaps the love of Coleridge for his college, "the ever honoured Jesus," might have had some share in the cause of his early predilection in favour of Hartley. He too was the son of a clergyman, was admitted to Jesus at the age of fifteen, and became a fellow in 1705. According to the account given of him by his biographer, Coleridge in several respects seems to have resembled him. All his early studies were intended to fit him for the church, but scruples arose in his mind, because he could not conscientiously subscribe to the thirty-nine articles: he therefore gave up all thoughts of the clerical profession, and entered the medical, for which, as Coleridge himself states, he also had had the most ardent desire. Hartley, when he had taken his degree, practised physic; and his knowledge, his general acquirements, his sensibility, and his benevolence, made him an ornament to the profession. In this profession too, Coleridge, had circumstances allowed him to enter it, must have been pre-eminent. Hartley, like Coleridge, was formed for sympathy and all the charities of life--his countenance was benign--his manners were gentle--and his eloquence pathetic and commanding. He first practised at Newark, and afterwards removed to Bury St. Edmonds, where he ended his career, dying in 1757, at the age of fifty-two. He was much afflicted with stone, and was in part the means of procuring from the government five thousand pounds for Mrs. Stevens, as a reward for the secret of preparing the solvent, sold and advertised in her name. In 1740, he published the work on which his fame rests, under the title of 'Observations on Man, his frame, his duty, and his expectations.' In it he expounded his doctrine of vibrations, and attempted by reasoning to explain the origin and propagation of sensation, built on gratuitous assumption of certain vibrations of the brain and nerves, coupled by association. Coleridge on his visit to Germany, soon made himself master of this subject. In his Biographia Literaria, he devotes a chapter to the examination of the work, and having seen the hollowness of the argument, abandoned it. While in Germany, Coleridge also studied Des Cartes, and saw the source of Locke's Theory, from which he entirely differed. He next turned his attention to Spinoza, but with a mind so logically formed, and so energetic in the search after truth, it was impossible for him to dwell long on a philosophy thus constructed--and Coleridge was still left to yearn for a resting place on which to base his faith. After he had successively studied in the schools of Locke, Berkeley, Leibnitz, and Hartley, and could find in one of them an abiding place for his reason;
