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 0rganum, 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.

By stimulating men to the discovery of new truth, Bacon stimulated them to employ the inductive method, the only method, even the ancient philosophers and the schoolmen themselves being judges, by which new truth can be discovered. By stimulating men to the discovery of useful truth, he furnished them with a motive to perform the inductive process well and carefully. His predecessors had been, in his phrase, not interpreters, but anticipators of nature. They had been content with the first principles at which they had arrived by the most scanty and slovenly induction. And why was this? It was, we conceive, because their philosophy proposed to itself no practical end, because it was merely an exercise of the mind. A man who wants to contrive a new machine or a new medicine has a strong motive to observe accurately and patiently, and to try experiment after experiment. But a man who merely wants a theme for disputation or declamation has no such motive. He is therefore content with premises grounded on assumption, or on the most scanty and hasty induction. Thus, we conceive, the schoolmen acted. On their foolish premises they often argued with great ability; and as their object was "assensum subjugare, non res," [Novum Organum, Lib. i. Aph. 29.] to be victorious in controversy not to be victorious over nature, they were consistent. For just as much logical skill could be shown in reasoning on false as on true premises. But the followers of the new philosophy, proposing to themselves the discovery of useful truth as their object, must have altogether failed of attaining that object if they had been content to build theories on superficial induction.

Bacon has remarked [De Augmentis, Lib. i.] that, in ages when philosophy was stationary, the mechanical arts went on improving. Why was this? Evidently because the mechanic was not content with so careless a mode of induction as served the purpose of the philosopher. And why was the philosopher more easily satisfied than the mechanic? Evidently because the object of the mechanic was to mould things, whilst the object of the philosopher was only to mould words. Careful induction is not at all necessary to the making of a good syllogism. But it is indispensable to the making of a good shoe. Mechanics, therefore, have always been, as far as the range of their humble but useful callings extended, not anticipators but interpreters of nature. And when a philosophy arose, the object of which was to do on a large scale what the mechanic does on a small scale, to extend the power and to supply the wants of man, the truth of the premises, which logically is a matter altogether unimportant, became a matter of the highest importance; and the careless induction with which men of learning had previously been satisfied gave place, of necessity, to an induction far more accurate and satisfactory.

What Bacon did for inductive philosophy may, we think, be fairly stated thus. The objects of preceding speculators were objects which could be attained without careful induction. Those speculators, therefore, did not perform the inductive process carefully. Bacon stirred up men to pursue an object which could be attained only by induction, and by induction carefully performed; and consequently induction was more carefully performed. We do not think that the importance of what Bacon did for inductive philosophy has ever been overrated. But we think that the nature of his services is often mistaken, and was not fully understood even by himself. It was not by furnishing philosophers with rules for performing the inductive process well, but by furnishing them with a motive for performing it well, that he conferred so vast a benefit on society.

To give to the human mind a direction which it shall retain for ages is the rare prerogative of a few imperial spirits. It cannot, therefore, be uninteresting to inquire what was the moral and intellectual constitution which enabled Bacon to exercise so vast an influence on the world.

In the temper of Bacon,-we speak of Bacon the philosopher, not of Bacon the lawyer and politician,-there was a singular union of audacity and sobriety. The promises which he made to mankind might, to a superficial reader, seem to resemble the rants which a great dramatist has put into the mouth of ail Oriental conqueror half-crazed by good fortune and by violent passions:

"He shall have chariots easier than air, Which I will have invented; and thyself That art the messenger shall ride before him, On a horse cut out of an entire diamond, That shall be made to go with golden wheels, I know not how yet."

But Bacon performed what he promised. In truth, Fletcher would not have dared to make Arbaces promise, in his wildest fits of excitement, the tithe of what the Baconian philosophy has performed.

The true philosophical temperament may, we think, be described in four words, much hope, little faith; a disposition to believe that anything, however extraordinary, may be done; an indisposition to believe that anything extraordinary has been done. In these points the constitution of Bacon's mind seems to us to have been absolutely perfect. He was at once the Mammon and the Surly of his friend Ben. Sir Epicure did not indulge in visions more magnificent and gigantic, Surly did not sift evidence with keener and more sagacious incredulity.

Closely connected with this peculiarity of Bacon's temper was a striking peculiarity of his understanding. With great minuteness of observation, he had an amplitude of comprehension such as has never yet been vouchsafed to any other human being. The small fine mind of Labruyere had not a more delicate tact than the large intellect of Bacon. The Essays contain abundant proofs that no nice feature of character, no peculiarity in the ordering of a house, a garden, or a court-masque, would escape the notice of one whose mind was capable of taking in the whole world of knowledge. His understanding resembled the tent which the fairy Paribanou gave to Prince Ahmed. Fold it; and it seemed a toy for the hand of a lady. Spread it; and the armies of powerful Sultans might repose beneath its shade.

In keenness of observation he has been equalled, though perhaps never surpassed. But the largeness of his mind was all his own. The glance with which he surveyed the intellectual universe resembled that which the Archangel, from the golden threshold of heaven, darted down into the new creation:

"Round he surveyed,-and well might, where he stood So high above the circling canopy Of night's extended shade,-from eastern point Of Libra, to the fleecy star which bears Andromeda far off Atlantic seas Beyond the horizon."

His knowledge differed from that of other men, as a terrestrial globe differs from an Atlas which contains a different country on every leaf. The towns and roads of England, France, and Germany are better laid down in the Atlas than on the globe. But while we are looking at England we see nothing of France; and while we are looking at France we see nothing of Germany. We may go to the Atlas to learn the bearings and distances of York and Bristol, or of Dresden and Prague. But it is useless if we want to know the bearings and distances of France and Martinique, or of England and Canada. On the globe we shall not find all the market towns in our own neighbourhood; but we shall learn from it the comparative extent and the relative position of all the kingdoms of the earth. "I have taken," said Bacon, in a letter written when he was only thirty-one, to his uncle Lord Burleigh, "I have taken all knowledge to be my province." In any other young man, indeed in any other man, this would have been a ridiculous flight of presumption. There have been thousands of better mathematicians, astronomers, chemists, physicians, botanists, mineralogists, than Bacon. No man would go to Bacon's works to learn any particular science or art, any more than he
