Knowledge may be gathered from the past through tradition. It may be accumulated and augmented by observation, but it must be proved and established by experimentation. No theory is important until it has been proved by method. Thus Bacon set up the machinery of control which has since become almost the fetish of science. Upon the solid foundation of the known, trained minds can build toward universal knowing, which is the end of the work.
Knowledge alone can preserve and perfect human life.
In spite of his scientific approach, Bacon in no way discounted the spiritual content in the world. Knowledge might arise from inspiration and the internal illumination of the consciousness, but this illumination is not knowledge until, through experimentation, the truth is physically established.
