It is divided into six parts. The first entitled Partitiones Scientiarum, or the divisions of knowledge possessed by mankind, in which the author has noted the deficiencies and imperfections of each. This he had already accomplished by his Advancement of Learning.
Part 2 is the Novum Organum Scientiarum, or new method of studying the sciences, a name probably suggested by Aristotle’s Organon (treatises on Logic). He intended it to be “the science of a better and more perfect use of reason in the investigation of things and of the true end of understanding.” This has been generally denominated the inductive method, i. e. the experimental method, from the principle of induction, or bringing together facts and drawing from them general principles or truths, by which the author proposes the advancement of all kinds of knowledge. In this consists preëminently the philosophy of Bacon. Not reasoning upon conjecture on the laws and properties of nature, but, as Bacon quaintly terms it, “asking questions of nature,” that is, making experiments, laboriously collecting facts first, and, after a sufficient number has been brought together, then forming systems or theories founded on them.
But this work is rather the summary of a more extensive one he designed, the aphorisms of it being rather, according to Hallam, “the heads or theses of chapters.” But some of these principles are of paramount importance. An instance may be afforded of this, extracted from the “Interpretation of Nature, and Man’s dominion over it.” It is the very first sentence in the Novum Organum. “Man, the servant and interpreter of nature, can only understand and act in proportion as he observes and contemplates the order of nature; more, he can neither know nor do.” This, as has justly been observed, is undoubtedly the foundation of all our real knowledge.
The Novum Organum is so important, that we deem it desirable to present some more detailed accounts of it.
The body of the work is divided into two parts; the former of which is intended to serve as an introduction to the other, a preparation of the mind for receiving the doctrine.
Bacon begins by endeavoring to remove the prejudices and to obtain fair attention to his doctrine. He compares philosophy to “a vast pyramid, which ought to have the history of nature for its basis;” he likens those who strive to erect by the force of abstract speculation to the giants of old, who, according to the poets, endeavored to throw Mount Ossa upon Pelion, and Olympus upon Ossa. The method of “anticipating nature,” he denounces “as rash, hasty, and unphilosophical;” whereas, “interpretations of nature, or real truths arrived at by deduction, cannot so suddenly arrest the mind; and when the conclusion actually arrives, it may so oppose prejudice, and appear so paradoxical as to be in danger of not being received, notwithstanding the evidence that supports it, like mysteries of faith.”
Bacon first attacks the “Idols of the Mind,” i. e. the great sources of prejudice, then the different false philosophical theories; he afterwards proceeds to show what are the characteristics of false systems, the causes of error in philosophy, and lastly the grounds of hope regarding the advancement of science.
He now aspires, to use his own language, “only to sow the seeds of pure truth for posterity, and not to be wanting in his assistance to the first beginning of great undertakings.” “Let the human race,” says he further, “regain their dominion over nature, which belongs to them by the bounty of their Maker, and right reason and sound religion will direct the use.”
The second part of the Novum Organum may be divided into three sections. The first is on the discovery of forms, i. e. causes in nature. The second section is composed of tables illustrative of the inductive method, and the third and last is styled the doctrine of instances, i. e. facts regarding the discovery of causes.
Part the third of the Instauratio Magna was to be a Natural History, as he termed it, or rather a history of natural substances, in which the art of man had been employed, which would have been a history of universal nature.
