Third part: Natural History. 38. The third part of the Instauratio Magna was to comprise an entire natural history, diligently and scrupulously collected from experience of every kind; including under that name of natural history everything wherein the art of man has been employed on natural substances either for practice or experiment; no method of reasoning being sufficient to guide us to truth as to natural things, if they are not themselves clearly and exactly apprehended. It is unnecessary to observe that very little of this immense chart of nature could be traced by the hand of Bacon, or in his time. His Centuries of Natural History, containing about one thousand observed facts and experiments, are a very slender contribution towards such a description of universal nature as he contemplated; these form no part of the Instauratio Magna, and had been compiled before. But he enumerates one hundred and thirty particular histories which ought to be drawn up for his great work. A few of these he has given in a sort of skeleton, as samples rather of the method of collecting facts, than of the facts themselves; namely, the History of Winds, of Life and Death, of Density and Rarity, of Sound and Hearing.
Fourth part: Scala Intellectûs. 39. The fourth part, called Scala Intellectûs, is also wanting with the exception of a very few introductory pages. “By these tables,” says Bacon, “we mean not such examples as we subjoin to the several rules of our method, but types and models, which place before our eyes the entire process of the mind in the discovery of truth, selecting various and remarkable instances.”[190] These he compares to the diagrams of geometry, by attending to which the steps of the demonstration become perspicuous. Though the great brevity of his language in this place renders it rather difficult to see clearly what he understood by these models, some light appears to be thrown on this passage by one in the treatise De Augmentis, where he enumerates among the desiderata of logic what he calls traditio lampadis, or a delivery of any science or particular truth according to the order wherein it was discovered.[191] “The methods of geometers,” he there says, “have some resemblance to this art;” which is not, however, the case as to the synthetical geometry with which we are generally conversant. It is the history of analytical investigation, and many beautiful illustrations of it have been given since the days of Bacon in all subjects to which that method of inquiry has been applied.
[190] Neque de iis exemplis loquimur, quæ singulis præceptis ac regulis illustrandi gratia adjiciuntur, hoc enim in secunda operis parte abunde præstitimus, sed plane typos intelligimus ac plasmata, quæ universum mentis processum atque inveniendi continuatam fabricam et ordinem in certis subjectis, iisque variis et insignibus tanquam sub oculos ponant. Etenim nobis venit in mentem in mathematicis, astente machina, sequi demonstrationem facilem et perspicuam; contra absque hac commoditate omnia videri involuta et quam revera sunt subtiliora.
[191] Lib. vi. cap. 2. Scientia quæ aliis tanquam tela pertexendo traditur, eadem methodo, si fieri possit, animo alterius est insinuanda, qua primitus inventa est. Atque hoc ipsum fieri sane potest in scientia per inductionem acquisita: sed in anticipata ista et præmatura scientia, qua utimur, non facile dicat quis quo itinere ad eam quam nactus est scientiam pervenerit. Attamen sane secundum majus et minus possit quis scientiam propriam revisere, et vestigia suæ cognitionis simul et consensûs remetiri; atque hoc facto scientiam sic transplantare in animum alienum, sicut crevit in suo.... Cujus quidem generis traditionis, methodus mathematicorum in eo subjecto similitudinem quandam habet. I do not well understand the words, in eo subjecto; he may possibly have referred to analytical processes.
Fifth part: Anticipationes Philosophiæ. 40. In the fifth part of the Instauratio Magna, Bacon had designed to give a specimen of the new philosophy which he hoped to raise after a due use of his natural history and inductive method, by way of anticipation or sample of the whole. He calls it Prodromi, sive Anticipationes Philosophiæ Secundæ. And some fragments of this part are published by the names Cogitata et Visa, Cogitationes de Natura Rerum, Filum Labyrinthi, and a few more, being as much, in all probability, as he had reduced to writing. In his own metaphor, it was to be like the payment of interest, till the principal could be raised; tanquam fœnus reddatur, donec sors haberi possit. |Sixth part: Philosophia Secunda.| For he despaired of ever completing the work by a sixth and last portion, which was to display a perfect system of philosophy, deduced and confirmed by a legitimate, sober, and exact inquiry according to the method which he had invented and laid down. “To perfect this last part is above our powers and beyond our hopes. We may, as we trust, make no despicable beginnings, the destinies of the human race must complete it; in such a manner, perhaps, as men, looking only at the present, would not readily conceive. For upon this will depend not only a speculative good, but all the fortunes of mankind, and all their power.” And with an eloquent prayer that his exertions may be rendered effectual to the attainment of truth and happiness, this introductory chapter of the Instauratio, which announces the distribution of its portions, concludes. Such was the temple, of which Bacon saw in vision before him the stately front and decorated pediments, in all their breadth of light and harmony of proportion, while long vistas of receding columns and glimpses of internal splendour revealed a glory that it was not permitted him to comprehend. In the treatise De Augmentis Scientiarum, and in the Novum Organum, we have less, no doubt, than Lord Bacon, under different conditions of life, might have achieved; he might have been more emphatically the high-priest of nature, if he had not been the chancellor of James I.; but no one man could have filled up the vast outline which he alone, in that stage of the world, could have so boldly sketched.
Course of studying Lord Bacon. 41. The best order of studying the Baconian philosophy would be to read attentively the Advancement of Learning; next, to take the treatise De Augmentis, comparing it all along with the former, and afterwards to proceed to the Novum Organum. A less degree of regard has usually been paid to the Centuries of Natural History, which are the least important of his writings, or even to the other philosophical fragments, some of which contain very excellent passages; yet such, in great measure, as will be found substantially in other parts of his works. The most remarkable are the Cogitata et Visa. It must be said, that one who thoroughly venerates Lord Bacon will not disdain his repetitions, which sometimes, by variations of phrase, throw light upon each other. It is generally supposed that the Latin works were translated by several assistants, among whom Herbert and Hobbes have been named, under the author’s superintendence.[192] The Latin style of these writings is singularly concise, energetic and impressive, but frequently crabbed, uncouth and obscure; so that we read with more admiration of the sense than delight in the manner of delivering it. But Rawley, in his Life of Bacon, informs us that he had seen about twelve autographs of the Novum Organum, wrought up and improved year by year, till it reached the shape in which it was published, and he does not intimate that these were in English, unless the praise he immediately afterwards bestows on his English style may be thought to warrant that supposition.[193] I do not know that we have evidence as to any of the Latin works being translations from English, except the treatise De Augmentis.
[192] The translation was made, as Archbishop Tenison informs us, “by Mr. Herbert and some others, who were esteemed masters in the Roman eloquence.”
[193] Ipse reperi in archivis dominationis suæ, autographa plus minus duodecim Organi Novi de anno in annum elaborati, et ad incudem revocati, et singulis annis, ulteriore lima subinde politi et castigati, donec in illud tandem corpus adoleverat, quo in lucem editum fuit; sicut multa ex animalibus fœtus lambere consuescunt usque quo ad membrorum firmitudinem eos perducant. In libris suis componendis verborum vigorem et perspicuitatem præcipuè sectabatur, non elegantiam aut concinnitatem sermonis, et inter scribendum aut dictandum sæpe interrogavit, num sensus ejus clare admodum et perspicuè redditus esset? Quippe qui sciret æquum esse ut verba famularentur rebus, non res verbis. Et si in stylum forsitan politiorem incidisset, siquidem apud nostrates eloquii Anglicani artifex habitus est, id evenit, quia evitare arduum ei erat.
42. The leading principles of the Baconian philosophy are contained in the Advancement of Learning. These are amplified, corrected, illustrated, and developed in the treatise De Augmentis Scientiarum, from the fifth book of which, with some help from other parts, is taken the first book of the Novum Organum, and even a part of the second. I use this phrase, because, though earlier in publication, I conceive that the Novum Organum was later in composition. All the very important part of this fifth book which relates to Experientia Litterata, or Venatio Panis, as he calls it, and contains excellent rules for conducting experiments in natural philosophy, is new, and does not appear in the Advancement of Learning, except by way of promise of what should be done in it. Nor is this, at least so fully and clearly, to be found in the Novum Organum. The second book of this latter treatise he professes not to anticipate. De Novo Organo silemus, he says, neque de eo quicquam prælibamus. This can only apply to the second book, which he considered as the real exposition of his method, after clearing away the fallacies which form the chief subject of the first. Yet what is said of Topica particularis, in this fifth book De Augmentis (illustrated by “articles of inquiry concerning gravity and levity”), goes entirely on the principles of the second book of the Novum Organum.
Nature of the Baconian Induction. 43. Let us now see what Lord Bacon’s method really was. He has given it the name of induction, but carefully distinguishes it from what bore that name in the old logic, that is, an inference from a perfect enumeration of particulars to a general law of the whole. For such an enumeration, though of course conclusive, is rarely practicable in nature, where the particulars exceed our powers of numbering.[194] Nor again is the Baconian method to be confounded with the less complete form of the inductive process, namely, inferences from partial experience in similar circumstances; though this may be a very sufficient ground for practical, which is probable knowledge. His own method rests on the same general principle, namely, the uniformity of the laws of nature, so that in certain conditions of phænomena the same effects or the same causes may be assumed; but it endeavours to establish these laws on a more exact and finer process of reasoning than partial experience can effect. For the recurrence of antecedents, and consequents does not prove a necessary connection between them, unless we can exclude the presence of all other conditions which may determine the event. Long and continued experience of such a recurrence, indeed, raises a high probability of a necessary connexion; but the aim of Bacon was to supersede experience in this sense, and to find a shorter road to the result; and for this his methods of exclusion are devised. As complete and accurate a collection of facts, connected with the subject of inquiry, as possible is to be made out by means of that copious natural history which he contemplated, or from any other good sources. These are to be selected, compared, and scrutinized, according to the rules of natural interpretation delivered in the second book of the Novum Organum, or such others as he designed to add to them; and if experiments are admissible, these are to be conducted according to the same rules. Experience and observation are the guides through the Baconian philosophy, which is the handmaid and interpreter of nature. When Lord Bacon seems to decry experience, which in certain passages he might be thought to do, it is the particular and empirical observation of individuals, from which many rash generalisations had been drawn, as opposed to that founded on an accurate natural history. Such hasty inferences he reckoned still more pernicious to true knowledge than the sophistical methods of the current philosophy; and, in a remarkable passage, after censuring this precipitancy of empirical conclusions in the chemists, and in Gilbert’s Treatise on the Magnet, utters a prediction that if ever mankind, excited by his counsels, should seriously betake themselves to seek the guidance of experience instead of relying on the dogmatic schools of the sophists, the proneness of the human mind to snatch at general axioms would expose them to much risk of error from the theories of this superficial class of philosophers.[195]
