Sir Francis Bacon, sometimes known as the father of empiricism, was one of the major political figures of his day, his career culminating as Lord Chancellor under King James I in 1617. Bacon wrote widely, but it is the Essays (published in its third edition in 1625, the year before his death) for which he is best known. Deftly written and often displaying a cutting wit, they cover a wide range of subjects including death, love, marriage, ambition and atheism.
