The Advancement of LearningFrancis Bacon

Bacon's The Advancement of Learning is at once a defense of learning against its detractors and a map of all human knowledge as it stood in 1605. The first book answers the charge that learning corrupts morals, unsettles government, or leads away from God. Bacon turns each objection on its head: it is ignorance, not knowledge, that breeds superstition and instability. Learning fails only when it degenerates into idle disputation, ornamental rhetoric, or slavish deference to authority.

The second book surveys the entire field of human knowledge, dividing knowledge according to the three faculties of the mind: memory (history), imagination (poetry), and reason (philosophy). Within each domain Bacon catalogs what has been accomplished and, more pointedly, what remains undone. These gaps, his "deficiences," are the real purpose of the work. They amount to a research program for centuries to come: systematic natural history, a reformed logic of discovery, a science of the mind, an honest study of rhetoric's power over judgment.

What holds the project together is Bacon's conviction that knowledge is not contemplation but operation. The purpose of understanding nature is to command it for "the relief of man's estate." This instrumental vision of learning, radical in its time, reorganized the relationship between philosophy, theology, and the practical sciences, and gave the empirical tradition its founding charter.
