LXXXVI–XCII. Men's childlike wonder at the arts and sciences has been reinforced by those who teach them. The reputation of the old ideas has been boosted by the empty claims of the supporters of new, practical natural philosophy. Arrogance, contempt, and lack of ambition have harmed the sciences. People claim that what they cannot achieve is impossible. Superstition and the blind zeal of religion have always hampered natural philosophy. In fact, natural philosophy should be the most powerful ally of religion. The manners and customs of schools and universities are inimical to the progress of the sciences. The lack of reward for discoveries also deters people; generally, those princes who control rewards are not learned. The greatest obstacle to progress, however, is the lack of hope, and the assumption that it is impossible.
XCIII–C. We must begin from God, who is the author of all things. Past errors and current methods give cause for hope, as they are so bad that they can only be improved upon. Empiricists are like ants; they accumulate and use. Rationalists spin webs like spiders. The best method is that of the bee; it is somewhere in between, taking existing material and using it. A pure form of natural philosophy is yet to be found. No one has yet done away with the jumble of common opinions and ideas, but if someone were to do so, great things could be achieved. The foundations of experience are weak; we can hope for better results when natural history (which is the foundation of natural philosophy) has been better organized. Further progress in science will be possible when we acquire illuminating experiments that reveal axioms rather than giving immediate profit. We need a new stock of experiments, and new methods and rules for proceeding.
CI–CXV. Experience needs to be written down to be really useful. Particulars need to be organized into tables of discovery relevant to the object of inquiry. More important things can be expected from axioms drawn from these particulars by a sure method. We must not allow the mind to proceed from particulars to general axioms, and then use those axioms to explain the particulars. Instead, we need to follow a kind of ladder, from particulars through intermediate axioms to abstract general axioms that are limited by the intermediate stage. A different form of induction is needed; it must not proceed by simple enumeration. It must separate out a nature by exclusions and rejections. This kind of induction can really define concepts and discover axioms. If the axiom being formed by this kind of induction has a wider scope than the particulars in question, then we should ask whether it points to new particulars. When these kind of axioms emerge, then a well-founded hope will appear. Other things may also give hope. Many more and better things can be hoped for from concerted human effort than from mere chance. It is very likely that many things remain to be discovered that we cannot currently imagine. The sheer number of particulars should restore hope; there are fewer things in nature than there are mental fictions. Bacon offers himself as a good role model; he has expanded knowledge whilst pursuing a political career. He seeks to remove despair, which has greatly delayed the progress of the sciences. This section, the destructive part of the Instauration, has rebutted native human reason left to itself, demonstrations and theories. This rebuttal has come from signs of causes. It is now time to approach the method of interpreting Nature. The purpose of the first book is to scrape the mind clean; Bacon now intends to set it in a favorable position towards his argument. He intends to create initial good impressions of what he will present, even before their real nature is known.
CXVI–CXXVIII. Bacon says he is not trying to found a new sect in philosophy. He is not working on matters of opinion, but trying to discover whether he can lay better foundations for human greatness and power in truth. He is not proposing a universal or complete theory, and does not expect to live to complete the final parts of the Instauration. His method is to draw causes and axioms from experiments, and from them new experiments. Those with the ability to do so can perform the experiments he describes and gain immediate results, but Bacon has larger concerns. If his natural history contains some mistakes, then that is only to be expected. His natural history may contain some common things, but this is because they are important and often neglected. Foul and mean things are also included; nothing is unworthy of inclusion. Bacon is interested only in enlightening experiments, not in productive ones; power over nature cannot be gained if we are uninterested in subtle or small matters. Bacon's method makes all intellects equal if they follow it; it is a product of its time rather than of his particular genius. It might be objected that Bacon has not declared the true goal of the sciences. Truth and usefulness in this inquiry are the same thing, but the goal of creating a true picture of the world is most important. Those who believe that Bacon will merely end by reproducing the methods of the ancients are mistaken; their methodology was flawed and fundamentally different. The idea that his hesitation to make judgments results in a lack of conviction is wrong. Rather, Bacon's method assists the senses and regulates the understanding. He also intends to perfect the sciences of ethics, logic and politics. He does not intend, however, to destroy the arts and sciences that he uses. The current disciplines should continue to provoke discussion, but little progress can be made until his new method is adopted.
CXXIX–CXXX. Bacon discusses the excellence of the Purpose. First, the introduction of remarkable discoveries holds first place amongst human actions. Political benefits are short-lived and limited compared to discoveries. The force and power of discoveries is evident in the three recent inventions that have changed the modern world; printing, gunpowder and the nautical compass. There are three forms of ambition; personal ambition, ambition for one's country, and the ambition to extend the power of the human race over the universe of things, which is the most majestic. Objections that the arts and sciences may lead to luxury and evil are unfounded. Right reason and sound religion will ensure the correct use of man's right over nature. It is now time to lay out the actual art of interpreting nature. Interpretation is the true and natural work of the mind once obstacles have been removed; it could be arrived at through intelligence, restraint and by laying aside received opinions. Bacon hopes that his work will speed up the process, however.
LXXXVI–XCII. Here, Bacon analyzes the factors acting against the new natural philosophy. The role of universities and colleges in propagating what Bacon believes to be false philosophy is considerable; the major institutions of learning in the seventeenth century were the source of the educated elite of European society. Bacon's own education at Trinity College, Cambridge presumably made him aware of the dominance of Aristotelian philosophy and the works of the "ancients" in general. Universities continued to teach Aristotelian doctrines up to the late seventeenth century, however, although new developments slowly made an impact. Bacon is hostile to many new developments that challenge traditional interpretations of nature, however. This hostility is in part criticism of his intellectual competitors, but it also reflects his keen awareness of the difficulty of his task. Flashy new systems that fail to deliver complete reform discredit the concept of the Great Renewal and might endanger the whole project. Bacon is keen to guard against this possibility.
