As a lawyer he became immediately successful; his knowledge and power of pleading became widely known, and it was almost at the beginning of his career that Jonson wrote, "The fear of every one that heard him speak was that he should make an end." The publication of his _Essays_ added greatly to his fame; but Bacon was not content. His head was buzzing with huge schemes,--the pacification of unhappy Ireland, the simplification of English law, the reform of the church, the study of nature, the establishment of a new philosophy. Meanwhile, sad to say, he played the game of politics for his personal advantage. He devoted himself to Essex, the young and dangerous favorite of the queen, won his friendship, and then used him skillfully to better his own position. When the earl was tried for treason it was partly, at least, through Bacon's efforts that he was convicted and beheaded; and though Bacon claims to have been actuated by a high sense of justice, we are not convinced that he understood either justice or friendship in appearing as queen's counsel against the man who had befriended him. His coldbloodedness and lack of moral sensitiveness appear even in his essays on "Love" and "Friendship." Indeed, we can understand his life only upon the theory that his intellectuality left him cold and dead to the higher sentiments of our humanity. During Elizabeth's reign Bacon had sought repeatedly for high office, but had been blocked by Burleigh and perhaps also by the queen's own shrewdness in judging men. With the advent of James I (1603) Bacon devoted himself to the new ruler and rose rapidly in favor. He was knighted, and soon afterwards attained another object of his ambition in marrying a rich wife. The appearance of his great work, the _Advancement of Learning_, in 1605, was largely the result of the mental stimulus produced by his change in fortune. In 1613 he was made attorney-general, and speedily made enemies by using the office to increase his personal ends. He justified himself in his course by his devotion to the king's cause, and by the belief that the higher his position and the more ample his means the more he could do for science. It was in this year that Bacon wrote his series of _State Papers_, which show a marvelous grasp of the political tendencies of his age. Had his advice been followed, it would have certainly averted the struggle between king and parliament that followed speedily. In 1617 he was appointed to his father's office, Lord Keeper of the Seal, and the next year to the high office of Lord Chancellor. With this office he received the title of Baron Verulam, and later of Viscount St. Alban, which he affixed with some vanity to his literary work. Two years later appeared his greatest work, the _Novum Organum_, called after Aristotle's famous _Organon_.
