His achievement was not the less great because it was indirect. His philosophical works, though little read now, "moved the intellects which moved the world." He made himself the eloquent voice of the optimism and resolution of the Renaissance. Never was any man so great a stimulus to other thinkers... The whole tenor and career of British thought have followed the philosophy of Bacon. His tendency to conceive the world in Democritean mechanical terms gave to his secretary, Hobbes, the starting-point for a thorough-going materialism; his inductive method gave to Locke the idea of an empirical psychology, bound by observation and freed from theology and metaphysics; and his emphasis on "commodities" and "fruits" found formulation in Bentham's identification of the useful and the good. Wherever the spirit of control has overcome the spirit of resignation, Bacon's influence has been felt. He is the voice of all those Europeans who have changed a continent from a forest into a treasure-land of art and science, and have made their little peninsula the center of the world... Everything is possible to man. Time is young; give us some little centuries, and we shall control and remake all things. We shall perhaps at last learn the noblest lesson of all, that man must not fight man, but must make war only on the obstacles that nature offers to the triumph of man.
