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.

Bacon did not long enjoy his political honors. The storm which had been long gathering against James's government broke suddenly upon Bacon's head. When Parliament assembled in 1621 it vented its distrust of James and his favorite Villiers by striking unexpectedly at their chief adviser. Bacon was sternly accused of accepting bribes, and the evidence was so great that he confessed that there was much political corruption abroad in the land, that he was personally guilty of some of it, and he threw himself upon the mercy of his judges. Parliament at that time was in no mood for mercy. Bacon was deprived of his office and was sentenced to pay the enormous fine of 40,000 pounds, to be imprisoned during the king's pleasure, and thereafter to be banished forever from Parliament and court. Though the imprisonment lasted only a few days and the fine was largely remitted, Bacon's hopes and schemes for political honors were ended; and it is at this point of appalling adversity that the nobility in the man's nature asserts itself strongly. If the reader be interested to apply a great man's philosophy to his own life, he will find the essay, "Of Great Place," most interesting in this connection.

Bacon now withdrew permanently from public life, and devoted his splendid ability to literary and scientific work. He completed the Essays, experimented largely, wrote history, scientific articles, and one scientific novel, and made additions to his Instauratio Magna, the great philosophical work which was never finished. In the spring of 1626, while driving in a snowstorm, it occurred to him that snow might be used as a preservative instead of salt. True to his own method of arriving at truth, he stopped at the first house, bought a fowl, and proceeded to test his theory. The experiment chilled him, and he died soon after from the effects of his exposure. As Macaulay wrote, "the great apostle of experimental philosophy was destined to be its martyr."

Works of Bacon. Bacon's philosophic works, The Advancement of Learning and the Novum Organum, will be best understood in connection with the Instauratio Magna, or The Great Institution of True Philosophy, of which they were parts. The Instauratio was never completed, but the very idea of the work was magnificent,--to sweep away the involved philosophy of the schoolmen and the educational systems of the universities, and to substitute a single great work which should be a complete education, "a rich storehouse for the glory of the Creator and for the relief of man's estate." The object of this education was to bring practical results to all the people, instead of a little selfish culture and much useless speculation, which, he conceived, were the only products of the universities.

The Instauratio Magna. This was the most ambitious, though it is not the best known, of Bacon's works. For the insight it gives us into the author's mind, we note here a brief outline of his subject. It was divided into six parts, as follows:

1. Partitiones Scientiarum. This was to be a classification and summary of all human knowledge. Philosophy and all speculation must be cast out and the natural sciences established as the basis of all education. The only part completed was The Advancement of Learning, which served as an introduction.

2. Novum Organum, or the "new instrument," that is, the use of reason and experiment instead of the old Aristotelian logic. To find truth one must do two things: (a) get rid of all prejudices or idols, as Bacon called them. These "idols" are four: "idols of the tribe," that is, prejudices due to common methods of thought among all races; "idols of the cave or den," that is, personal peculiarities and prejudices; "idols of the market place," due to errors of language; and "idols of the theater," which are the unreliable traditions of men. (b) After discarding the above "idols" we must interrogate nature; must collect facts by means of numerous experiments, arrange them in order, and then determine the law that underlies them.

It will be seen at a glance that the above is the most important of Bacon's works. The Organum was to be in several books, only two of which he completed, and these he wrote and rewrote twelve times until they satisfied him.

3. Historic Naturalis et Experimentalis, the study of all the phenomena of nature. Of four parts of this work which he completed, one of them at least, the Sylva Sylvarum, is decidedly at variance with his own idea of fact and experiment. It abounds in fanciful explanations, more worthy of the poetic than of the scientific mind. Nature is seen to be full of desires and instincts; the air "thirsts" for light and fragrance; bodies rise or sink because they have an "appetite" for height or depth; the qualities of bodies are the result of an "essence," so that when we discover the essences of gold and silver and diamonds it will be a simple matter to create as much of them as we may need.

4. Scala Intellectus, or "Ladder of the Mind," is the rational application of the Organum to all problems. By it the mind should ascend step by step from particular facts and instances to general laws and abstract principles.
