Francis Bacon (1561-1626)
2. Thought and Writings
These late productions represented the capstone of a writing career that spanned more than four decades and encompassed virtually an entire curriculum of literary, scientific, and philosophical studies.
a. Literary Work
Despite the fanatical claims (and very un-Baconian credulity) of a few admirers, it is a virtual certainty that Bacon did not write the works traditionally attributed to William Shakespeare. Even so, the Lord Chancellor’s high place in the history of English literature as well as his influential role in the development of English prose style remain well-established and secure. Indeed even if Bacon had produced nothing else but his masterful Essayes (first published in 1597 and then revised and expanded in 1612 and 1625), he would still rate among the top echelon of 17th-century English authors. And so when we take into account his other writings, e.g., his histories, letters, and especially his major philosophical and scientific works, we must surely place him in the first rank of English literature’s great men of letters and among its finest masters (alongside names like Johnson, Mill, Carlyle, and Ruskin) of non-fiction prose.
Bacon’s style, though elegant, is by no means as simple as it seems or as it is often described. In fact it is actually a fairly complex affair that achieves its air of ease and clarity more through its balanced cadences, natural metaphors, and carefully arranged symmetries than through the use of plain words, commonplace ideas, and straightforward syntax. (In this connection it is noteworthy that in the revised versions of the essays Bacon seems to have deliberately disrupted many of his earlier balanced effects to produce a style that is actually more jagged and, in effect, more challenging to the casual reader.)
Furthermore, just as Bacon’s personal style and living habits were prone to extravagance and never particularly austere, so in his writing he was never quite able to resist the occasional grand word, magniloquent phrase, or orotund effect. (As Dr. Johnson observed, “A dictionary of the English language might be compiled from Bacon’s works alone.”) Bishop Sprat in his 1667 History of the Royal Society honored Bacon and praised the society membership for supposedly eschewing fine words and fancy metaphors and adhering instead to a natural lucidity and “mathematical plainness.” To write in such a way, Sprat suggested, was to follow true, scientific, Baconian principles. And while Bacon himself often expressed similar sentiments (praising blunt expression while condemning the seductions of figurative language), a reader would be hard pressed to find many examples of such spare technique in Bacon’s own writings. Of Bacon’s contemporary readers, at least one took exception to the view that his writing represented a perfect model of plain language and transparent meaning. After perusing the New Organon, King James (to whom Bacon had proudly dedicated the volume) reportedly pronounced the work “like the peace of God, which passeth all understanding.”
b. The New Atlantis
As a work of narrative fiction, Bacon’s novel New Atlantis may be classified as a literary rather than a scientific (or philosophical) work, though it effectively belongs to both categories. According to Bacon’s amanuensis and first biographer William Rawley, the novel represents the first part (showing the design of a great college or institute devoted to the interpretation of nature) of what was to have been a longer and more detailed project (depicting the entire legal structure and political organization of an ideal commonwealth). The work thus stands in the great tradition of the utopian-philosophical novel that stretches from Plato and More to Huxley and Skinner.
The thin plot or fable is little more than a fictional shell to contain the real meat of Bacon’s story: the elaborate description of Salomon’s House (also known as the College of the Six Days Works), a centrally organized research facility where specially trained teams of investigators collect data, conduct experiments, and (most importantly from Bacon’s point of view) apply the knowledge they gain to produce “things of use and practice for man’s life.” These new arts and inventions they eventually share with the outside world.
In terms of its sci-fi adventure elements, the New Atlantis is about as exciting as a government or university re-organization plan. But in terms of its historical impact, the novel has proven to be nothing less than revolutionary, having served not only as an effective inspiration and model for the British Royal Society, but also as an early blueprint and prophecy of the modern research center and international scientific community.
c. Scientific and Philosophical Works
It is never easy to summarize the thought of a prolific and wide-ranging philosopher. Yet Bacon somewhat simplifies the task by his own helpful habits of systematic classification and catchy mnemonic labeling. (Thus, for example, there are three “distempers” – or diseases – of learning,” eleven errors or “peccant humours,” four “Idols,” three primary mental faculties and categories of knowledge, etc.) In effect, by following Bacon’s own methods it is possible to produce a convenient outline or overview of his main scientific and philosophical ideas.
As early as 1592, in a famous letter to his uncle, Lord Burghley, Bacon declared “all knowledge” to be his province and vowed his personal commitment to a plan for the full-scale rehabilitation and reorganization of learning. In effect, he dedicated himself to a long-term project of intellectual reform, and the balance of his career can be viewed as a continuing effort to make good on that pledge. In 1620, while he was still at the peak of his political success, he published the preliminary description and plan for an enormous work that would fully answer to his earlier declared ambitions. The work, dedicated to James, was to be called Magna Instauratio (i.e., the “grand edifice” or Great Instauration), and it would represent a kind of summa or culmination of all Bacon’s thought on subjects ranging from logic and epistemology to practical science (or what in Bacon’s day was called “natural philosophy,” the word science being then but a general synonym for “wisdom” or “learning”).
Like several of Bacon’s projects, the Instauratio in its contemplated form was never finished. Of the intended six parts, only the first two were completed, while the other portions were only partly finished or barely begun. Consequently, the work as we have it is less like the vast but well-sculpted monument that Bacon envisioned than a kind of philosophical miscellany or grab-bag. Part I of the project, De Dignitate et Augmentis Scientiarum (“Nine Books of the Dignity and Advancement of Learning”), was published in 1623. It is basically an enlarged version of the earlier Proficience and Advancement of Learning, which Bacon had presented to James in 1605. Part II, the Novum Organum (or “New Organon”) provides the author’s detailed explanation and demonstration of the correct procedure for interpreting nature. It first appeared in 1620. Together these two works present the essential elements of Bacon’s philosophy, including most of the major ideas and principles that we have come to associate with the terms “Baconian” and “Baconianism.”
e. The Advancement of Learning
Relatively early in his career Bacon judged that, owing mainly to an undue reverence for the past (as well as to an excessive absorption in cultural vanities and frivolities), the intellectual life of Europe had reached a kind of impasse or standstill. Yet he believed there was a way beyond this stagnation if persons of learning, armed with new methods and insights, would simply open their eyes and minds to the world around them. This at any rate was the basic argument of his seminal 1605 treatise The Proficience and Advancement of Learning, arguably the first important philosophical work to be published in English.
It is in this work that Bacon sketched out the main themes and ideas that he continued to refine and develop throughout his career, beginning with the notion that there are clear obstacles to or diseases of learning that must be avoided or purged before further progress is possible.
f. The “Distempers” of Learning
“There be therefore chiefly three vanities in studies, whereby learning hath been most traduced.” Thus Bacon, in the first book of the Advancement. He goes on to refer to these vanities as the three “distempers” of learning and identifies them (in his characteristically memorable fashion) as “fantastical learning,” “contentious learning,” and “delicate learning” (alternatively identified as “vain imaginations,” “vain altercations,” and “vain affectations”).
By fantastical learning (“vain imaginations”) Bacon had in mind what we would today call pseudo-science: i.e., a collection of ideas that lack any real or substantial foundation, that are professed mainly by occultists and charlatans, that are carefully shielded from outside criticism, and that are offered largely to an audience of credulous true believers. In Bacon’s day such “imaginative science” was familiar in the form of astrology, natural magic, and alchemy.
By contentious learning (“vain altercations”) Bacon was referring mainly to Aristotelian philosophy and theology and especially to the Scholastic tradition of logical hair-splitting and metaphysical quibbling. But the phrase applies to any intellectual endeavor in which the principal aim is not new knowledge or deeper understanding but endless debate cherished for its own sake.
Delicate learning (“vain affectations”) was Bacon’s label for the new humanism insofar as (in his view) it seemed concerned not with the actual recovery of ancient texts or the retrieval of past knowledge but merely with the revival of Ciceronian rhetorical embellishments and the reproduction of classical prose style. Such preoccupation with “words more than matter,” with “choiceness of phrase” and the “sweet falling of clauses” – in short, with style over substance – seemed to Bacon (a careful stylist in his own right) the most seductive and decadent literary vice of his age.
- Prodigal ingenuity – i.e., each distemper represents a lavish and regrettable waste of talent, as inventive minds that might be employed in more productive pursuits exhaust their energy on trivial or puerile enterprises instead.
- Sterile results – i.e., instead of contributing to the discovery of new knowledge (and thus to a practical “advancement of learning” and eventually to a better life for all), the distempers of learning are essentially exercises in personal vainglory that aim at little more than idle theorizing or the preservation of older forms of knowledge.
In short, in Bacon’s view the distempers impede genuine intellectual progress by beguiling talented thinkers into fruitless, illusory, or purely self-serving ventures. What is needed – and this is a theme reiterated in all his later writings on learning and human progress – is a program to re-channel that same creative energy into socially useful new discoveries.
g. The Idea of Progress
Though it is hard to pinpoint the birth of an idea, for all intents and purposes the modern idea of technological “progress” (in the sense of a steady, cumulative, historical advance in applied scientific knowledge) began with Bacon’s The Advancement of Learning and became fully articulated in his later works.
Knowledge is power, and when embodied in the form of new technical inventions and mechanical discoveries it is the force that drives history – this was Bacon’s key insight. In many respects this idea was his single greatest invention, and it is all the more remarkable for its having been conceived and promoted at a time when most English and European intellectuals were either reverencing the literary and philosophical achievements of the past or deploring the numerous signs of modern degradation and decline. Indeed, while Bacon was preaching progress and declaring a brave new dawn of scientific advance, many of his colleagues were persuaded that the world was at best creaking along towards a state of senile immobility and eventual darkness. “Our age is iron, and rusty too,” wrote John Donne, contemplating the signs of universal decay in a poem published six years after Bacon’s Advancement.
That history might in fact be progressive, i.e., an onward and upward ascent – and not, as Aristotle had taught, merely cyclical or, as cultural pessimists from Hesiod to Spengler have supposed, a descending or retrograde movement, became for Bacon an article of secular faith which he propounded with evangelical force and a sense of mission. In the Advancement, the idea is offered tentatively, as a kind of hopeful hypothesis. But in later works such as the New Organon, it becomes almost a promised destiny: Enlightenment and a better world, Bacon insists, lie within our power; they require only the cooperation of learned citizens and the active development of the arts and sciences.
h. The Reclassification of Knowledge
In Book II of De Dignitate (his expanded version of the Advancement) Bacon outlines his scheme for a new division of human knowledge into three primary categories: History, Poesy, and Philosophy (which he associates respectively with the three fundamental “faculties” of mind – memory, imagination, and reason). Although the exact motive behind this reclassification remains unclear, one of its main consequences seems unmistakable: it effectively promotes philosophy – and especially Baconian science – above the other two branches of knowledge, in essence defining history as the mere accumulation of brute facts, while reducing art and imaginative literature to the even more marginal status of “feigned history.”Evidently Bacon believed that in order for a genuine advancement of learning to occur, the prestige of philosophy (and particularly natural philosophy) had to be elevated, while that of history and literature (in a word, humanism) needed to be reduced. Bacon’s scheme effectively accomplishes this by making history (the domain of fact, i.e., of everything that has happened) a virtual sub-species of philosophy (the domain of realistic possibility, i.e., of everything that can theoretically or actually occur). Meanwhile, poesy (the domain of everything that is imaginable or conceivable) is set off to the side as a mere illustrative vehicle. In essence, it becomes simply a means of recreating actual scenes or events from the past (as in history plays or heroic poetry) or of allegorizing or dramatizing new ideas or future possibilities (as in Bacon’s own interesting example of “parabolic poesy,” the New Atlantis.)
i. The New Organon
To the second part of his Great Instauration Bacon gave the title New Organon (or “True Directions concerning the Interpretation of Nature”). The Greek word organon means “instrument” or “tool,” and Bacon clearly felt he was supplying a new instrument for guiding and correcting the mind in its quest for a true understanding of nature. The title also glances at Aristotle’s Organon (a collection that includes his Categories and his Prior and Posterior Analytics) and thus suggests a “new instrument” destined to transcend or replace the older, no longer serviceable one. (This notion of surpassing ancient authority is aptly illustrated on the frontispiece of the 1620 volume containing the New Organon by a ship boldly sailing beyond the mythical pillars of Hercules, which supposedly marked the end of the known world.)
The New Organon is presented not in the form of a treatise or methodical demonstration but as a series of aphorisms, a technique that Bacon came to favor as less legislative and dogmatic and more in the true spirit of scientific experiment and critical inquiry. Combined with his gift for illustrative metaphor and symbol, the aphoristic style makes the New Organon in many places the most readable and literary of all Bacon’s scientific and philosophical works.
j. The Idols
In Book I of the New Organon (Aphorisms 39-68), Bacon introduces his famous doctrine of the “idols.” These are characteristic errors, natural tendencies, or defects that beset the mind and prevent it from achieving a full and accurate understanding of nature. Bacon points out that recognizing and counteracting the idols is as important to the study of nature as the recognition and refutation of bad arguments is to logic. Incidentally, he uses the word “idol” – from the Greek eidolon (“image” or “phantom”) – not in the sense of a false god or heathen deity but rather in the sense employed in Epicurean physics. Thus a Baconian idol is a potential deception or source of misunderstanding, especially one that clouds or confuses our knowledge of external reality.
Bacon identifies four different classes of idol. Each arises from a different source, and each presents its own special hazards and difficulties.
At the beginning of the Magna Instauratio and in Book II of the New Organon, Bacon introduces his system of “true and perfect Induction,” which he proposes as the essential foundation of scientific method and a necessary tool for the proper interpretation of nature. (This system was to have been more fully explained and demonstrated in Part IV of the Instauratio in a section titled “The Ladder of the Intellect,” but unfortunately the work never got beyond an introduction.)
According to Bacon, his system differs not only from the deductive logic and mania for syllogisms of the Schoolmen, but also from the classic induction of Aristotle and other logicians. As Bacon explains it, classic induction proceeds “at once from . . . sense and particulars up to the most general propositions” and then works backward (via deduction) to arrive at intermediate propositions. Thus, for example, from a few observations one might conclude (via induction) that “all new cars are shiny.” One would then be entitled to proceed backward from this general axiom to deduce such middle-level axioms as “all new Lexuses are shiny,” “all new Jeeps are shiny,” etc. – axioms that presumably would not need to be verified empirically since their truth would be logically guaranteed as long as the original generalization (“all new cars are shiny”) is true.
As Bacon rightly points out, one problem with this procedure is that if the general axioms prove false, all the intermediate axioms may be false as well. All it takes is one contradictory instance (in this case one new car with a dull finish) and “the whole edifice tumbles.” For this reason Bacon prescribes a different path. His method is to proceed “regularly and gradually from one axiom to another, so that the most general are not reached till the last.” In other words, each axiom – i.e., each step up “the ladder of intellect” – is thoroughly tested by observation and experimentation before the next step is taken. In effect, each confirmed axiom becomes a foothold to a higher truth, with the most general axioms representing the last stage of the process.
Thus, in the example described, the Baconian investigator would be obliged to examine a full inventory of new Chevrolets, Lexuses, Jeeps, etc., before reaching any conclusions about new cars in general. And while Bacon admits that such a method can be laborious, he argues that it eventually produces a stable edifice of knowledge instead of a rickety structure that collapses with the appearance of a single disconfirming instance. (Indeed, according to Bacon, when one follows his inductive procedure, a negative instance actually becomes something to be welcomed rather than feared. For instead of threatening an entire assembly, the discovery of a false generalization actually saves the investigator the trouble of having to proceed further in a particular direction or line of inquiry. Meanwhile the structure of truth that he has already built remains intact.)
Is Bacon’s system, then, a sound and reliable procedure, a strong ladder leading from carefully observed particulars to true and “inevitable” conclusions? Although he himself firmly believed in the utility and overall superiority of his method, many of his commentators and critics have had doubts. For one thing, it is not clear that the Baconian procedure, taken by itself, leads conclusively to any general propositions, much less to scientific principles or theoretical statements that we can accept as universally true. For at what point is the Baconian investigator willing to make the leap from observed particulars to abstract generalizations? After a dozen instances? A thousand? The fact is, Bacon’s method provides nothing to guide the investigator in this determination other than sheer instinct or professional judgment, and thus the tendency is for the investigation of particulars – the steady observation and collection of data – to go on continuously, and in effect endlessly.
One can thus easily imagine a scenario in which the piling up of instances becomes not just the initial stage in a process, but the very essence of the process itself; in effect, a zealous foraging after facts (in the New Organon Bacon famously compares the ideal Baconian researcher to a busy bee) becomes not only a means to knowledge, but an activity vigorously pursued for its own sake. Every scientist and academic person knows how tempting it is to put off the hard work of imaginative thinking in order to continue doing some form of rote research. Every investigator knows how easy it is to become wrapped up in data – with the unhappy result that one’s intended ascent up the Baconian ladder gets stuck in mundane matters of fact and never quite gets off the ground.
It was no doubt considerations like these that prompted the English physician (and neo-Aristotelian) William Harvey, of circulation-of-the-blood fame, to quip that Bacon wrote of natural philosophy “like a Lord Chancellor” – indeed like a politician or legislator rather than a practitioner. The assessment is just to the extent that Bacon in the New Organon does indeed prescribe a new and extremely rigid procedure for the investigation of nature rather than describe the more or less instinctive and improvisational – and by no means exclusively empirical – method that Kepler, Galileo, Harvey himself, and other working scientists were actually employing. In fact, other than Tycho Brahe, the Danish astronomer who, overseeing a team of assistants, faithfully observed and then painstakingly recorded entire volumes of astronomical data in tidy, systematically arranged tables, it is doubtful that there is another major figure in the history of science who can be legitimately termed an authentic, true-blooded Baconian. (Darwin, it is true, claimed that The Origin of Species was based on “Baconian principles.” However, it is one thing to collect instances in order to compare species and show a relationship among them; it is quite another to theorize a mechanism, namely evolution by mutation and natural selection, that elegantly and powerfully explains their entire history and variety.)
Science, that is to say, does not, and has probably never advanced according to the strict, gradual, ever-plodding method of Baconian observation and induction. It proceeds instead by unpredictable – and often intuitive and even (though Bacon would cringe at the word) imaginative – leaps and bounds. Kepler used Tycho’s scrupulously gathered data to support his own heart-felt and even occult belief that the movements of celestial bodies are regular and symmetrical, composing a true harmony of the spheres. Galileo tossed unequal weights from the Leaning Tower as a mere public demonstration of the fact (contrary to Aristotle) that they would fall at the same rate. He had long before satisfied himself that this would happen via the very un-Bacon-like method of mathematical reasoning and deductive thought-experiment. Harvey, by a similar process of quantitative analysis and deductive logic, knew that the blood must circulate, and it was only to provide proof of this fact that he set himself the secondary task of amassing empirical evidence and establishing the actual method by which it did so.
One could enumerate – in true Baconian fashion – a host of further instances. But the point is already made: advances in scientific knowledge have not been achieved for the most part via Baconian induction (which amounts to a kind of systematic and exhaustive survey of nature supposedly leading to ultimate insights) but rather by shrewd hints and guesses – in a word by hypotheses – that are then either corroborated or (in Karl Popper’s important term) falsified by subsequent research.
In summary, then, it can be said that Bacon underestimated the role of imagination and hypothesis (and overestimated the value of minute observation and bee-like data collection) in the production of new scientific knowledge. And in this respect it is true that he wrote of science like a Lord Chancellor, regally proclaiming the benefits of his own new and supposedly foolproof technique instead of recognizing and adapting procedures that had already been tested and approved. On the other hand, it must be added that Bacon did not present himself (or his method) as the final authority on the investigation of nature or, for that matter, on any other topic or issue relating to the advance of knowledge. By his own admission, he was but the Buccinator, or “trumpeter,” of such a revolutionary advance – not the founder or builder of a vast new system, but only the herald or announcing messenger of a new world to come.
