Chapter 43

Bacon has been accused of overrating the importance of those sciences which minister to the physical well-being of man, and of underrating the importance of moral philosophy; and it cannot be denied that persons who read the Novum Organum and the De Augmentis, without adverting to the circumstances under which those works were written, will find much that may seem to countenance the accusation. It is certain, however, that, though in practice he often went very wrong, and though, as his historical work and his essays prove, he did not hold, even in theory, very strict opinions on points of political morality, he was far too wise a man not to know how much our well-being depends on the regulation of our minds. The world for which he wished was not, as some people seem to imagine, a world of water-wheels, power-looms, steam-carriages, sensualists, and knaves. He would have been as ready as Zeno himself to maintain that no bodily comforts which could be devised by the skill and labour of a hundred generations would give happiness to a man whose mind was under the tyranny of licentious appetite, of envy, of hatred, or of fear. If he sometimes appeared to ascribe importance too exclusively to the arts which increase the outward comforts of our species, the reason is plain. Those arts had been most unduly depreciated. They had been represented as unworthy of the attention of a man of liberal education. “Cogitavit,” says Bacon of himself, “eam esse opinionem sive aestimationem humidam et damnosam, minui nempe majestatem mentis humanae, si in experimentis et rebus particularibus, sensui subjectis, et in materia terminatis, diu ac multum versetur: praesertim cum hujusmodi res ad inquirendum laboriosae, ad meditandum ignobiles, ad discendum asperae, ad practicam illiberales, numero infinitae, et subtilitate pusillae videri soleant, et ob hujusmodi conditiones, gloriae artium minus sint accommodatae.” [Cogitata et visa. The expression opinio humida may surprise a reader not accustomed to Bacon’s style. The allusion is to the maxim of Heraclitus the obscure: “Dry light is the best.” By dry light, Bacon understood the light of the intellect, not obscured by the mists of passion, interest, or prejudice.] This opinion seemed to him “omnia in familia humana turbasse.” It had undoubtedly caused many arts which were of the greatest utility, and which were susceptible of the greatest improvements, to be neglected by speculators, and abandoned to joiners, masons, smiths, weavers, apothecaries. It was necessary to assert the dignity of those arts, to bring them prominently forward, to proclaim that, as they have a most serious effect on human happiness, they are not unworthy of the attention of the highest human intellects. Again, it was by illustrations drawn from these arts that Bacon could most easily illustrate his principles. It was by improvements effected in these arts that the soundness of his principles could be most speedily and decisively brought to the test, and made manifest to common understandings. He acted like a wise commander who thins every other part of his line to strengthen a point where the enemy is attacking with peculiar fury, and on the fate of which the event of the battle seems likely to depend. In the Novum Organum, however, he distinctly and most truly declares that his philosophy is no less a Moral than a Natural Philosophy, that, though his illustrations are drawn from physical science, the principles which those illustrations are intended to explain are just as applicable to ethical and political inquiries as to inquiries into the nature of heat and vegetation. [Novum Organum, Lib, I. Aph 127.]

He frequently treated of moral subjects; and he brought to those subjects that spirit which was the essence of his whole system. He has left us many admirable practicable observations on what he somewhat quaintly called the Georgics of the mind, on the mental culture which tends to produce good dispositions. Some persons, he said, might accuse him of spending labour on a matter so simple that his predecessors had passed it by with contempt. He desired such persons to remember that he had from the first announced the objects of his search to be not the splendid and the surprising, but the useful and the true, not the deluding dreams which go forth through the shining portal of ivory, but the humbler realities of the gate of horn. [De Augmentis, Lib. vii. Cap. 3.]

True to this principle, he indulged in no rants about the fitness of things, the all-sufficiency of virtue, and the dignity of human nature. He dealt not at all in resounding nothings, such as those with which Bolingbroke pretended to comfort himself in exile, and in which Cicero vainly sought consolation after the loss of Tullia. The casuistical subtilties which occupied the attention of the keenest spirits of his age had, it should seem, no attractions for him. The doctors whom Escobar afterwards compared to the four beasts and the four-and-twenty elders in the Apocalypse Bacon dismissed with most contemptuous brevity. “Inanes plerumque evadunt et futiles.” [Ibid. Lib. vii. Cap. 2.] Nor did he ever meddle with those enigmas which have puzzled hundreds of generations, and will puzzle hundreds more. He said nothing about the grounds of moral obligation, or the freedom of the human will. He had no inclination to employ himself in labours resembling those of the damned in the Grecian Tartarus, to spin for ever on the same wheel round the same pivot, to gape for ever after the same deluding clusters, to pour water for ever into the same bottomless buckets, to pace for ever to and fro on the same wearisome path after the same recoiling stone. He exhorted his disciples to prosecute researches of a very different description, to consider moral science as a practical science, a science of which the object was to cure the diseases and perturbations of the mind, and which could be improved only by a method analogous to that which has improved medicine and surgery. Moral philosophers ought, he said, to set themselves vigorously to work for the purpose of discovering what are the actual effects produced on the human character by particular modes of education, by the indulgence of particular habits, by the study of particular books, by society, by emulation, by imitation. Then we might hope to find out what mode of training was most likely to preserve and restore moral health. [Ibid.: Lib. vii. Cap. 3.]

What he was as a natural philosopher and a moral philosopher, that he was also as a theologian. He was, we are convinced, a sincere believer in the divine authority of the Christian revelation. Nothing can be found in his writings, or in any other writings, more eloquent and pathetic than some passages which were apparently written under the influence of strong devotional feeling. He loved to dwell on the power of the Christian religion to effect much that the ancient philosophers could only promise. He loved to consider that religion as the bond of charity, the curb of evil passions, the consolation of the wretched, the support of the timid, the hope of the dying. But controversies on speculative points of theology seem to have engaged scarcely any portion of his attention. In what he wrote on Church Government he showed, as far as he dared, a tolerant and charitable spirit. He troubled himself not at all about Homoousians and Homoiousians, Monothelites and Nestorians. He lived in an age in which disputes on the most subtle points of divinity excited an intense interest throughout Europe, and nowhere more than in England. He was placed in the very thick of the conflict. He was in power at the time of the Synod of Dort, and must for months have been daily deafened with talk about election, reprobation, and final perseverance. Yet we do not remember a line in his works from which it can be inferred that he was either a Calvinist or an Arminian. While the world was resounding with the noise of a disputatious philosophy and a disputatious theology, the Baconian school, like Allworthy seated between Square and Thwackum, preserved a calm neutrality, half scornful, half benevolent, and content with adding to the sum of practical good, left the war of words to those who liked it.

We have dwelt long on the end of the Baconian philosophy, because from this peculiarity all the other peculiarities of that philosophy necessary arose. Indeed, scarcely any person who proposed to himself the same end with Bacon could fail to hit upon the same means.

The vulgar notion about Bacon we take to be this, that he invented a new method of arriving at truth, which method is called Induction, and that he detected some fallacy in the syllogistic reasoning which had been in vogue before his time. This notion is about as well founded as that of the people who, in the middle ages, imagined that Virgil was a great conjurer. Many who are far too well-informed to talk such extravagant nonsense entertain what we think incorrect notions as to what Bacon really effected in this matter.

The inductive method has been practised ever since the beginning of the world by every human being. It is constantly practised by the most ignorant clown, by the most thoughtless schoolboy, by the very child at the breast. That method leads the clown to the conclusion that if he sows barley he shall not reap wheat. By that method the schoolboy learns that a cloudy day is the best for catching trout. The very infant, we imagine, is led by induction to expect milk from his mother or nurse, and none from his father.

Not only is it not true that Bacon invented the inductive method; but it is not true that he was the first person who correctly analysed that method and explained its uses. Aristotle had long before pointed out the absurdity of supposing that syllogistic reasoning could ever conduct men to the discovery of any new principle, had shown that such discoveries must be made by induction, and by induction alone, and had given the history of the inductive process, concisely indeed, but with great perspicuity and precision.

Again, we are not inclined to ascribe much practical value to that analysis of the inductive method which Bacon has given, in the second book of the Novum Organum. It is indeed an elaborate and correct analysis. But it is an analysis of that which we are all doing from morning to night, and which we continue to do even in our dreams. A plain man finds his stomach out of order. He never heard Lord Bacon’s name. But he proceeds in the strictest conformity with the rules laid down in the second book of the Novum Organum, and satisfies himself that minced pies have done the mischief. “I ate minced pies on Monday and Wednesday, and I was kept awake by indigestion all night.” This is the comparentia ad intellectum instantiarum convenientium. “I did not eat any on Tuesday and Friday, and I was quite well.” This is the comparentia instantiarum in proximo quae natura data privantur. “I ate very sparingly of them on Sunday, and was very slightly indisposed in the evening. But on Christmas-day I almost dined on them, and was so ill that I was in great danger.” This is the comparentia instantiarum secundum magis et minus. “It cannot have been the brandy which I took with them. For I have drunk brandy daily for years without being the worse for it.” This is the rejectio naturarum. Our invalid then proceeds to what is termed by Bacon the Vindemiatio, and pronounces that minced pies do not agree with him.

We repeat that we dispute neither the ingenuity nor the accuracy of the theory contained in the second book of the Novum Organum; but we think that Bacon greatly overrated its utility. We conceive that the inductive process, like many other processes, is not likely to be better performed merely because men know how they perform it. William Tell would not have been one whit more likely to cleave the apple if he had known that his arrow would describe a parabola under the influence of the attraction of the earth. Captain Barclay would not have been more likely to walk a thousand miles in a thousand hours, if he had known the place and name of every muscle in his legs. Monsieur Jourdain probably did not pronounce D and F more correctly after he had been apprised that D is pronounced by touching the teeth with the end of the tongue, and F by putting the upper teeth on the lower lip. We cannot perceive that the study of grammar makes the smallest difference in the speech of people who have always lived in good society. Not one Londoner in ten thousand can lay down the rules for the proper use of will and shall. Yet not one Londoner in a million ever misplaces his will and shall. Dr. Robertson could, undoubtedly, have written a luminous dissertation on the use of those words. Yet, even in his latest work, he sometimes misplaced them ludicrously. No man uses figures of speech with more propriety because he knows that one figure is called a metonymy and another a synecdoche. A drayman in a passion calls out, “You are a pretty fellow.”, without suspecting that he is uttering irony, and that irony is one of the four primary tropes. The old systems of rhetoric were never regarded by the most experienced and discerning judges as of any use for the purpose of forming an orator. “Ego hanc vim intelligo,” said Cicero, “esse in praeceptis omnibus, non ut ea secuti oratores eloquentiae laudem sint adepti, sed quae sua sponte homines eloquentes facerent, ea quosdam observasse, atque id egisse; sic esse non eloquentiam ex artificio, sed artificium ex eloquentia natum.” We must own that we entertain the same opinion concerning the study of Logic which Cicero entertained concerning the study of Rhetoric. A man of sense syllogises in celarent and cesare all day long without suspecting it; and, though he may not know what an ignoratio elenchi is, has no difficulty in exposing it whenever he falls in with it; which is likely to be as often as he falls in with a Reverend Master of Arts nourished on mode and figure in the cloisters of Oxford. Considered merely as an intellectual feat, the Organum of Aristotle can scarcely be admired too highly. But the more we compare individual with individual, school with school, nation with nation, generation with generation, the more do we lean to the opinion that the knowledge of the theory of logic has no tendency whatever to make men good reasoners.

What Aristotle did for the syllogistic process Bacon has, in the second book of the Novum Organum, done for the inductive process; that is to say, he has analysed it well. His rules are quite proper, but we do not need them, because they are drawn from our own constant practice.

But, though everybody is constantly performing the process described in the second book of the Novum Organum, some men perform it well and some perform it ill. Some are led by it to truth, and some to error. It led Franklin to discover the nature of lightning. It led thousands, who had less brains than Franklin, to believe in animal magnetism. But this was not because Franklin went through the process described by Bacon, and the dupes of Mesmer through a different process. The comparentiae and rejectiones of which we have given examples will be found in the most unsound inductions. We have heard that an eminent judge of the last generation was in the habit of jocosely propounding after dinner a theory, that the cause of the prevalence of Jacobinism was the practice of bearing three names. He quoted on the one side Charles James Fox, Richard Brinsley Sheridan, John Horne Tooke, John Philpot Curran, Samuel Taylor Coleridge, Theobald Wolfe Tone. These were instantiae convenientes. He then proceeded to cite instances absentiae in proximo, William Pitt, John Scott, William Windham, Samuel Horsley, Henry Dundas, Edmund Burke. He might have gone on to instances secundum magis et minus. The practice of giving children three names has been for some time a growing practice, and Jacobinism has also been growing. The practice of giving children three names is more common in America than in England. In England we still have a King and a House of Lords; but the Americans are Republicans. The rejectiones are obvious. Burke and Theobald Wolfe Tone are both Irishmen: therefore the being an Irishman is not the cause of Jacobinism. Horsley and Horne Tooke are both clergymen; therefore the being a clergyman is not the cause of Jacobinism. Fox and Windham were both educated at Oxford; therefore the being educated at Oxford is not the cause of Jacobinism. Pitt and Horne Tooke were both educated at Cambridge; therefore the being educated at Cambridge is not the cause of Jacobinism. In this way, our inductive philosopher arrives at what Bacon calls the Vintage, and pronounces that the having three names is the cause of Jacobinism.

Here is an induction corresponding with Bacon’s analysis and ending in a monstrous absurdity. In what then does this induction differ from the induction which leads us to the conclusion that the presence of the sun is the cause of our having more light by day than by night? The difference evidently is not in the kind of instances, but in the number of instances; that is to say, the difference is not in that part of the process for which Bacon has given precise rules, but in a circumstance for which no precise rule can possibly be given. If the learned author of the theory about Jacobinism had enlarged either of his tables a little, his system would have been destroyed. The names of Tom Paine and William Wyndham Grenville would have been sufficient to do the work.

It appears to us, then, that the difference between a sound and unsound induction does not lie in this, that the author of the sound induction goes through the process analysed in the second book of the Novum Organum, and the author of the unsound induction through a different process. They both perform the same process. But one performs it foolishly or carelessly; the other performs it with patience, attention, sagacity, and judgment. Now precepts can do little towards making men patient and attentive, and still less towards making them sagacious and judicious. It is very well to tell men to be on their guard against prejudices, not to believe facts on slight evidence, not to be content with a scanty collection of facts, to put out of their minds the idola which Bacon has so finely described. But these rules are too general to be of much practical use. The question is, What is a prejudice? How long does the incredulity with which I hear a new theory propounded continue to be a wise and salutary incredulity? When does it become an idolum specus, the unreasonable pertinacity of a too sceptical mind? What is slight evidence? What collection of facts is scanty? Will ten instances do, or fifty, or a hundred? In how many months would the first human beings who settled on the shores of the ocean have been justified in believing that the moon had an influence on the tides? After how many experiments would Jenner have been justified in believing that he had discovered a safeguard against the small-pox? These are questions to which it would be most desirable to have a precise answer; but, unhappily, they are questions to which no precise answer can be returned.

We think, then, that it is possible to lay down accurate rules, as Bacon has done, for the performing of that part of the inductive process which all men perform alike; but that these rules, though accurate, are not wanted, because in truth they only tell us to do what we are all doing. We think that it is impossible to lay down any precise rule for the performing of that part of the inductive process which a great experimental philosopher performs in one way, and a superstitious old woman in another.

On this subject, we think, Bacon was in an error. He certainly attributed to his rules a value which did not belong to them. He went so far as to say, that, if his method of making discoveries were adopted, little would depend on the degree of force or acuteness of any intellect; that all minds would be reduced to one level, that his philosophy resembled a compass or a rule which equalises all hands, and enables the most unpractised person to draw a more correct circle or line than the best draftsmen can produce without such aid. [Novum Organum, Praef. and Lib. I Aph. 122.] This really seems to us as extravagant as it would have been in Lindley Murray to announce that everybody who should learn his Grammar would write as good English as Dryden, or in that very able writer, the Archbishop of Dublin, to promise that all the readers of his Logic would reason like Chillingworth, and that all the readers of his Rhetoric would speak like Burke. That Bacon was altogether mistaken as to this point will now hardly be disputed. His philosophy has flourished during two hundred years, and has produced none of this levelling. The interval between a man of talents and a dunce is as wide as ever; and is never more clearly discernible than when they engage in researches which require the constant use of induction.

It will be seen that we do not consider Bacon’s ingenious analysis of the inductive method as a very useful performance. Bacon was not, as we have already said, the inventor of the inductive method. He was not even the person who first analysed the inductive method correctly, though he undoubtedly analysed it more minutely than any who preceded him. He was not the person who first showed that by the inductive method alone new truth could be discovered. But he was the person who first turned the minds of speculative men, long occupied in verbal disputes, to the discovery of new and useful truth; and, by doing so, he at once gave to the inductive method an importance and dignity which had never before belonged to it. He was not the maker of that road; he was not the discoverer of that road; he was not the person who first surveyed and mapped that road. But he was the person who first called the public attention to an inexhaustible mine of wealth, which had been utterly neglected, and which was accessible by that road alone. By doing so he caused that road, which had previously been trodden only by peasants and higglers, to be frequented by a higher class of travellers.

That which was eminently his own in his system was the end which he proposed to himself. The end being given, the means, as it appears to us, could not well be mistaken. If others had aimed at the same object with Bacon, we hold it to be certain that they would have employed the same method with Bacon. It would have been hard to convince Seneca that the inventing of a safety-lamp was an employment worthy of a philosopher. It would have been hard to persuade Thomas Aquinas to descend from the making of syllogisms to the making of gunpowder. But Seneca would never have doubted for a moment that it was only by means of a series of experiments that a safety-lamp could be invented. Thomas Aquinas would never have thought that his barbara and baralipton would enable him to ascertain the proportion which charcoal ought to bear to saltpetre in a pound of gunpowder. Neither common sense nor Aristotle would have suffered him to fall into such an absurdity.
