He is the author of Academic Progress (1605) and New Tools (1620). Bacon sharply criticized the scholasticism in the Middle Ages, holding that scholasticism and theology seriously hindered the progress of science, and advocated thoroughly transforming human knowledge, liberating the whole academic culture from scholasticism and realizing great rejuvenation. He believes that science must pursue the causes and laws of natural things. To achieve this goal, it must be based on sensory experience. He put forward the principles of materialism and empiricism, and believed that knowledge and ideas originated from the perceptual world, and sensory experience was the source of all knowledge. In order to acquire scientific knowledge about nature, we must base our knowledge on sensory experience. He also put forward the empirical induction method, which advocated that based on the experimental and observation materials, after analysis, comparison, selection and exclusion, the correct conclusion was finally drawn.
