Francis Bacon, English philosopher and Chancellor, was born on January 22, 1561, the son of Lord Keeper Bacon, was sent to Trinity College, Cambridge, in 1573, and entered Gray's Inn in 1576. He had already become profoundly dissatisfied at Cambridge with the Aristotelian philosophy, and the conception of a humble and methodical study of Nature had early become the dominant passion of his life. Bacon became a member of parliament in 1584, and nine years later distinguished himself by coming forward as the champion of the privileges of the House of Commons against the Lords. The "Essays" were published in 1597. Bacon was knighted in 1603, on the accession of James I. In October, 1605, he published the "Advancement of Learning," a work designed to interest the king in the new philosophy, of which book we here give a summary. This review of the existing state of knowledge was intended to be made, later, into the first part of the "Instauratio Magna" under the title of "Partitiones Scientiarum." For this purpose Bacon was constantly revising it, and eventually he had it translated into Latin, and it was so published, greatly enlarged, in 1623, under the title of "De Dignitate et Augmentis Scientiarum." The summit of his career was reached in 1621, when he became Viscount St. Albans. His fall, on a charge of corruptions in the Court of Chancery, took place in the following March, and from this period until his death, on April 9, 1626, he devoted himself to his philosophical and literary works. _First Book_ Let us weigh the dignity of knowledge in the balance with other things. In its archetype it is the Divine wisdom, or sapience, manifested in the creation. In the celestial hierarchy the supposed Dionysius of Athens places the angels of knowledge and illumination before those of office and domination. Then, the first material form that was created was light, which corresponds in corporal things to knowledge in incorporai. The day wherein God contemplated His own works was blessed above the days wherein He accomplished them. Man's first employment in Paradise consisted of the two chief parts of knowledge, the view of creatures, and the imposition of names. In the age before the Flood, Scripture honours the names of the inventors of music and of works in metal. Moses was accomplished in all the learning of the Egyptians. The book of Job is pregnant with natural philosophy. In Solomon, the gift of wisdom and learning is preferred before all other earthly and temporal felicity.
