[222] Brucker, v. 95. Stewart says that “Bayle does not give above twelve lines to Bacon;” but he calls him one of the greatest men of his age, and the length of an article in Bayle was never designed to be a measure of the merit of its subject.
[223] It is not uncommon to meet with persons, especially who are or have been engaged in teaching others dogmatically what they have themselves received in the like manner, to whom the inductive philosophy appears a mere school of scepticism, or at best wholly inapplicable to any subjects which require entire conviction. A certain deduction from certain premises is the only reasoning they acknowledge. This is peculiarly the case with theologians, but it is also extended to everything which is taught in a synthetic manner. Lord Bacon has a remarkable passage on this in the 9th book De Augmentis. Postquam articuli et principia religionis jam in sedibus suis fuerint locata, ita ut a rationis examine penitus eximantur, tum demum conceditur ab illis illationes derivare ac deducere, secundum analogiam ipsorum. In rebus quidem naturalibus hoc non tenet. Nam et ipsa principia examini subjiciuntur; per inductionem, inquam, licet minime per syllogismum. Atque eadem illa nullam habent cum ratione repugnantiam, ut ab eodem fonte cum primæ propositiones, tum mediæ, deducantur. Aliter fit in religione; ubi et primæ propositiones authopystatæ sunt, atque per se subsistentes; et rursus non reguntur ab illa ratione quæ propositiones consequentes deducit. Neque tamen hoc fit in religione sola, sed etiam in aliis scientiis, tam gravioribus, quam levioribus, ubi scilicet propositiones humanæ placita sunt, non posita; siquidem et in illis rationis usus absolutus esse non potest. Videmus enim in ludis, puta schaccorum, aut similibus, priores ludi normas et leges merè positivas esse, et ad placitum; quas recipi, non in disputationem vocari, prorsus oporteat; ut vero vincas, et peritè lusum instituas, id artificiosum est et rationale. Eodem modo fit et in legibus humanis; in quibus haud paucæ sunt maximæ, ut loquuntur, hoc est, placita mera juris, quæ auctoritate magis quam ratione nituntur, neque in disceptationem veniunt. Quid vero sit justissimum, non absolutè, sed relativè, hoc est ex analogiâ illarum maximarum, id demum rationale est, et latum disputationi campum præbet. This passage, well weighed, may show us where, why, and by whom the synthetic and syllogistic methods have been preferred to the inductive and analytical.
[224] The De Augmentis was only once published after the first edition, in 1638. An indifferent translation, by Gilbert Watts, came out in 1640. No edition of Bacon’s Works was published in England before 1730; another appeared in 1740, and there have been several since. But they had been printed at Frankfort in 1665. It is unnecessary to observe, that many copies of the foreign editions were brought to this country. This is mostly taken from Mr. Montague’s account.
[225] I have met, since this passage was written, with one in Stewart’s Life of Reid, which seems to state the effects of Bacon’s philosophy in a just and temperate spirit, and which I rather quote, because this writer has, by his eulogies on that philosophy, led some to an exaggerated notion. “The influence of Bacon’s genius on the subsequent progress of physical discovery has been seldom duly appreciated: by some writers almost entirely overlooked, and by others considered as the sole cause of the reformation in science which has since taken place. Of these two extremes, the latter certainly is the least wide of the truth: for in the whole history of letters no other individual can be mentioned whose exertions have had so indisputable an effect in forwarding the intellectual progress of mankind. On the other hand, it must be acknowledged that before the era when Bacon appeared, various philosophers in different parts of Europe had struck into the right path; and it may perhaps be doubted, whether any one important rule with respect to the true method of investigation be contained in his works, of which no hint can be traced in those of his predecessors. His great merit lay in concentrating their feeble and scattered lights; fixing the attention of philosophers on the distinguishing characteristics of true and of false science, by a felicity of illustration peculiar to himself, seconded by the commanding powers of a bold and figurative eloquence. The method of investigation which he recommended had been previously followed in every instance in which any solid discovery had been made with respect to the laws of nature; but it had been followed accidentally and without any regular preconceived design; and it was reserved for him to reduce to rule and method what others had effected, either fortuitously, or from some momentary glimpse of the truth. These remarks are not intended to detract from the just glory of Bacon; for they apply to all those, without exception, who have systematised the principles of any of the arts. Indeed, they apply less forcibly to him than to any other philosopher whose studies have been directed to objects analogous to his; inasmuch as we know of no art of which the rules have been reduced successfully into a didactic form, when the art itself was as much in infancy as experimental philosophy was when Bacon wrote.” Account of Life and writings of Reid sect. 2.
On the Metaphysical Philosophy of Descartes.
Early life of Descartes. 81. René Descartes was born in 1596 of an ancient family in Touraine. An inquisitive curiosity into the nature and causes of all he saw is said to have distinguished his childhood, and this was certainly accompanied by an uncommon facility and clearness of apprehension. At a very early age he entered the college of the Jesuits at La Fleche, and passed through their entire course of literature and philosophy. It was now, at the age of sixteen, as he tells us, that he began to reflect, with little satisfaction, on his studies, finding his mind beset with error, and obliged to confess that he had learned nothing but the conviction of his ignorance. Yet he knew that he had been educated in a famous school, and that he was not deemed behind his contemporaries. The ethics, the logic, even the geometry of the ancients, did not fill his mind with that clear stream of truth, for which he was ever thirsting. On leaving La Fleche, the young Descartes mingled for some years in the world, and served as a volunteer both under Prince Maurice, and in the Imperial army. Yet during this period there were intervals when he withdrew himself wholly from society, and devoted his leisure to mathematical science. Some germs also of his peculiar philosophy were already ripening in his mind.
His beginning to philosophise. 82. Descartes was twenty-three years old when, passing a solitary winter in his quarters at Neuburg on the Danube, he began to resolve in his mind the futility of all existing systems of philosophy, and the discrepancy of opinions among the generality of mankind, which rendered it probable that no one had yet found out the road to real science. He determined, therefore, to set about the investigation of truth for himself, erasing from his mind all preconceived judgments, as having been hastily and precariously taken up. He laid down for his guidance a few fundamental rules of logic, such as to admit nothing as true which he did not clearly perceive, and to proceed from the simpler notions to the more complex, taking the method of geometers, by which they had gone so much farther than others, for the true art of reasoning. Commencing, therefore, with the mathematical sciences, and observing that, however different in their subjects, they treat properly of nothing but the relations of quantity, he fell, almost accidentally, as his words seem to import, on the great discovery that geometrical curves may be expressed algebraically.[226] This gave him more hope of success in applying his method to other parts of philosophy.

He retires to Holland. 83. Nine years more elapsed, during which Descartes, though he quitted military service, continued to observe mankind in various parts of Europe, still keeping his heart fixed on the great aim he had proposed to himself, but, as he confesses, without having framed the scheme of any philosophy beyond those of his contemporaries. He deemed his time of life immature for so stupendous a task. But at the age of thirty-three, with little notice to his friends, he quitted Paris, convinced that absolute retirement was indispensable for that rigorous investigation of first principles he now determined to institute, and retired into Holland. In this country he remained eight years so completely aloof from the distractions of the world, that he concealed his very place of residence, though preserving an intercourse of letters with many friends in France.
