FRANCIS BACON.--Francis Bacon, lawyer, member of Parliament, Lord Chancellor of England, personal friend of James I, friend, protector, and perhaps collaborator with Shakespeare, overthrown as the result of political animosity and relegated to private life, was a very learned man with a marvellous mind. Like his namesake, Roger Bacon, but in an age more favourable to intellectual reform, he attempted a sort of renewal of the human mind (_Instauratio Magna_) or at least a radical revolution in the methods and workings of the human mind. Although Francis Bacon professed admiration for many of the thinkers of antiquity, he urged that it was wrong to rely on them because they had not sufficiently observed; one must not, like the schoolmen, have ideas _a priori_, which are "idols," and there are idols of tribe, of party, of school, of eras; intentions must not be perceived everywhere in nature, and we must not, because the sun warms, believe it was created to warm, or because the earth yields nourishment believe her creation was for the purpose of feeding us, and that all things converge to man and are put at his service. It is necessary to proceed by observation, by experiment, and then by induction, but with prodigious mistrust of induction. Induction consists in drawing conclusions from the particular to the general, from a certain number of facts to a law. This is legitimate on condition that the conclusion is not drawn from a few facts to a law, which is precipitate induction, fruitful in errors; but from a very large number of facts to a law, which even then is considered as provisional. As for metaphysics, as for the investigation of universal law, that should be entirely separated from philosophy itself, from the "primary philosophy" which does not lead to it; it has its own field, which is that of faith: "Give to faith what belongeth to faith." In the main he is uninterested in metaphysics, believing them always to revolve in a circle and, I do not say, only believes in science and in method, but has hope only from knowledge and method, an enthusiast in this respect just as another might be about the super-sensible world or about ideas, saying human knowledge and human power are really coincident, and believing that knowledge will support humanity in all calamities, will prolong human life, will establish a new golden age, etc.
