Francis Bacon (1561–1626) was an English philosopher, statesman, scientist, and author who served as Attorney General and Lord Chancellor of England. He is widely regarded as the father of the scientific method and a pioneer of empiricism. His philosophical works, particularly the Novum Organum (1620) and The Advancement of Learning (1605), argued that knowledge should be built through systematic observation, experimentation, and inductive reasoning rather than through reliance on ancient authorities or abstract logic. He identified what he called the "Idols of the Mind"—four categories of cognitive bias and error (Idols of the Tribe, Cave, Marketplace, and Theatre) that distort human understanding and must be overcome through disciplined inquiry. Bacon envisioned a grand reorganization of all human knowledge, which he called the "Great Instauration," aimed at giving humanity mastery over nature for the relief of suffering. His utopian work The New Atlantis imagined a society organized around a scientific research institution, an idea that helped inspire the founding of the Royal Society. His political career ended in disgrace when he was convicted of accepting bribes in 1621, though he maintained the payments had not influenced his judgments. Despite this fall, his intellectual legacy endured: his vision of science as a collaborative, empirical enterprise dedicated to practical improvement fundamentally shaped the modern world.
