Fame of his system and attacks upon it. 109. A system so novel, so attractive to the imagination by its bold and brilliant paradoxes as that of Descartes, could not but excite the attention of an age already roused to the desire of a new philosophy, and to the scorn of ancient authority. His first treatises appeared in French; and, though he afterwards employed Latin, his works were very soon translated by his disciples, and under his own care. He wrote in Latin with great perspicuity; in French with liveliness and elegance. His mathematical and optical writings gave him a reputation which envy could not take away, and secured his philosophy from that general ridicule which sometimes overwhelms an obscure author. His very enemies, numerous and vehement as they were, served to enhance the celebrity of the Cartesian system, which he seems to have anticipated by publishing their objections to his Meditations with his own replies. In the universities, bigoted for the most part to Aristotelian authority, he had no chance of public reception; but the influence of the universities was much diminished in France, and a new theory had perhaps better chances in its favour on account of their opposition. But the Jesuits, a more powerful body, were in general adverse to the Cartesian system, and especially some time afterwards, when it was supposed to have the countenance of several leading Jansenists. The Epicurean school, led by Gassendi and Hobbes, presented a formidable phalanx; since it in fact comprehended the wits of the world, the men of indolence and sensuality, quick to discern the many weaknesses of Cartesianism, with no capacity for its excellencies. It is unnecessary to say, how predominant this class was in the seventeenth and eighteenth centuries, both in France and England.

Controversy with Voet. 110. Descartes was evidently in considerable alarm lest the church should bear with its weight upon his philosophy.[260] He had the censure on Galileo before his eyes, and certainly used some chicane of words as to the earth’s movement upon this account. It was, however, in the Protestant country, which he had chosen as his harbour of refuge, that he was doomed to encounter the roughest storm. Gisbert Voet, an eminent theologian in the university of Utrecht, and the head of the party in the church of Holland, which had been victorious in the synod of Dort, attacked Descartes with all the virulence and bigotry characteristic of his school of divinity. The famous demonstration of the being of God he asserted to be a cover for atheism, and thus excited a flame of controversy, Descartes being not without supporters in the university, especially Regius, professor of medicine. The philosopher was induced by these assaults to change his residence from a town in the province of Utrecht to Leyden. Voet did not cease to pursue him with outrageous calumny, and succeeded in obtaining decrees of the senate and university, which interdicted Regius from teaching that “new and unproved (præsumpta) philosophy” to his pupils. The war of libels on the Voetian side did not cease for some years, and Descartes replied with no small acrimony against Voet himself. The latter had recourse to the civil power, and instituted a prosecution against Descartes, which was quashed by the interference of the prince of Orange. But many in the university of Leyden, under the influence of a notable theologian of that age, named Triglandius, one of the stoutest champions of Dutch orthodoxy, raised a cry against the Cartesian philosophy as being favourable to Pelagianism and popery, the worst names that could be given in Holland; and it was again through the protection of the prince of Orange that he escaped a public censure. Regius, the most zealous of his original advocates, began to swerve from the fidelity of a sworn disciple, and published a book containing some theories of his own, which Descartes thought himself obliged to disavow. Ultimately he found, like many benefactors of mankind, that he had purchased reputation at the cost of peace; and, after some visits to France, where, probably from the same cause, he never designed to settle, found an honourable asylum and a premature death at the court of Christina. He died in 1651, having worked a more important change in speculative philosophy than any who had preceded him since the revival of learning; for there could be no comparison, in that age, between the celebrity and effect of his writings and those of Lord Bacon. The latter had few avowed enemies, till it was too late to avow enmity.[261]

[260] On a tellement assujetti la théologie à Aristotle, qu’il est impossible d’expliquer une autre philosophie qu’il ne semble d’abord qu’elle soit contre la foi. Et à propos de ceci, je vous prie de me mander s’il n’y a rien de déterminé en la foi touchant l’étendue du monde: savoir s’il est fini ou plutôt infini, et si tout ce qu’on appelle espaces imaginaires soient des corps créés et véritables. Vol. vi., p. 73.

[261] The life of Descartes was written, very fully and with the warmth of a disciple, by Baillet, in two volumes quarto, 1691, of which he afterwards published an abridgment. In this we find at length the attacks made on him by the Voetian theologians. Brucker has given a long and valuable account of the Cartesian philosophy, but not favourable, and perhaps not quite fair. Vol. v., p. 200-334. Buhle is, as usual, much inferior to Brucker. But those who omit the mathematical portion will not find the original works of Descartes very long, and they are well worthy of being read.

Charges of plagiarism. 111. The prejudice against Descartes, especially in his own country, was aggravated by his indiscreet and not very warrantable assumption of perfect originality.[262] No one, I think, can fairly refuse to own, that the Cartesian metaphysics, taken in their consecutive arrangement, form truly an original system; and it would be equally unjust to deny the splendid discoveries he developed in algebra and optics. But upon every one subject which Descartes treated, he has not escaped the charge of plagiarism; professing always to be ignorant of what had been done by others, he falls perpetually into their track; more, as his adversaries maintained, than the chances of coincidence could fairly explain. Leibnitz has summed up the claims of earlier writers to the pretended discoveries of Descartes; and certainly it is a pretty long bill to be presented to any author. I shall insert this passage in a note, though much of it has no reference to this portion of the Cartesian philosophy.[263] It may perhaps be thought by candid minds, that we cannot apply the doctrine of chances to coincidence of reasoning in men of acute and inquisitive spirits, as fairly as we may to that of style or imagery; but, if we hold strictly that the older writer may claim the exclusive praise of the philosophical discovery, we must regret to see such a multitude of feathers plucked from the wing of an eagle.

[262] I confess, he says in his logic, that I was born with such a temper, that the chief pleasure I find in study is not from the learning the arguments of others, but by inventing my own. This disposition alone impelled me in youth to the study of science; hence, whenever a new book promised by its title some new discovery, before sitting down to read it, I used to try whether my own natural sagacity could lead me to anything of the kind, and I took care not to lose this innocent pleasure by too hasty a perusal. This answered so often that I at length perceived that I arrived at truth, not as other men do after blind and precarious guesses, by good luck rather than skill, but that long experience had taught me certain fixed rules, which were of surprising utility, and of which I afterwards made use to discover more truths. Vol. xi., p. 252.

[263] Dogmata ejus metaphysica, velut circa ideas a sensibus remotas, et animæ distinctionem a corpore, et fluxam per se rerum materialium fidem, prorsus Platonica sunt. Argumentum pro existentia Dei, ex eo, quod ens perfectissimum, vel quo majus intelligi non potest, existentiam includit, fuit Anselmi, et in libro “Contra insipientem” inscripto extat inter ejus opera, passimque a scholasticis examinatur. In doctrina de continuo, pleno et loco Aristotelem noster secutus est, Stoicosque in re morali penitus expressit, floriferis ut apes in saltibus omnia libant. In explicatione rerum mechina Leucippum et Democritum præeuntes habuit, qui et vortices ipsos jam docuerant. Jordanus Brunus easdem fere de magnitudine universi ideas habuisse dicitur, quemadmodum et notavit V. CC. Stephanus Spleissius, ut de Gilberto nil dicam, cujus magneticæ considerationes tum per se, tum ad systema universi applicatæ, Cartesio plurimum profuerunt. Explicationem gravitatis per materiæ solidioris rejectionem in tangente, quod in physica Cartesiana prope pulcherrimum est, didicit ex Keplero, qui similitudine palearum motu aquæ in vase gyrantis ad centrum contrusarum rem explicuit primus. Actionem lucis in distans, similitudine baculi pressi jam veteres adumbravere. Circa iridem a M. Antonio de Dominis non parum lucis accepit. Keplerum fuisse primum suum in dioptricis magistrum, et in eo argumento omnes ante se mortales longo intervallo antegressum, fatetur Cartesius in epistolis familiaribus; nam in scriptis, quæ ipse edidit, longè abest a tali confessione aut laude, tametsi illa ratio, quæ rationum dictionem explicat, et compositione nimirum duplicis conatûs perpendicularis ad superficiem et ad eandem paralleli, disertè apud Keplerum extet, qui eodem, ut Cartesius, modo æqualitatem angulorum incidentiæ et reflexionis hinc deducit. Idque gratam mentionem ideo merebatur, quod omnis prope Cartesii ratiocinatio huic innititur principio. Legem refractionis primum invenisse Willebroodum Snellium, Isaacus Vossius patefecit, quanquam non ideo negare ausim, Cartesium in eadem incidere potuisse de suo. Negavit in epistolis Vietam sibi lectum, sed Thomæ Harrioti Angli libros analyticos posthumos anno 1631 editos vidisse multi vix dubitant; usque adeo magnus est eorum consensus cum calculo geometriæ Cartesianæ. Sane jam Harriotus æquationem nihilo æqualem posuit, et hinc derivavit, quomodo oriatur æquatio ex multiplicatione radicum in se invicem, et quomodo radiorum auctione, diminutione, multiplicatione aut divisione variari æquatio possit, et quomodo proinde natura, et constitutio æquationem et radicum cognosci possit ex terminorum habitudine. Itaque narrat celeberrimus Wallisius, Robervalium, qui miratus erat, unde Cartesio in mentem venisset palmarium illud, æquationem ponere æqualem nihilo ad instar unius quantitatis, ostenso sibi a Domino de Cavendish libro Harrioti exclamasse, il l’a vu! il l’a vu! vidit, vidit. Reductionem quadratoquadratæ æquationis ad cubicam superiori jam sæculo invenit Ludovicus Ferrarius, cujus vitam reliquit Cardanus ejus familiaris. Denique fuit Cartesius, ut a viris doctis dudum notatum est, et ex epistolis nimium apparet, immodicus contemptor aliorum, et famæ cupiditate ab artificiis non abstinens, quæ parum generosa videri possunt. Atque hæc profecto non dico animo obtrectandi viro, quem mirificè æstimo, sed eo consilio, ut cuique suum tribuatur, nec unus omnium laudes absorbeat; justissimum enim est, ut inventoribus suus honos constet, nec sublatis virtutum præmiis præclara faciendi studium refrigescat. Leibnitz, apud Brucker, v. 255.

Recent increase of his fame. 112. The name of Descartes as a great metaphysical writer has revived in some measure of late years; and this has been chiefly owing, among ourselves, to Dugald Stewart; in France, to the growing disposition of their philosophers to cast away their idols of the eighteenth century. “I am disposed,” says our Scottish philosopher, “to date the origin of the true philosophy of mind from the Principia (why not the earlier works?) of Descartes, rather than from the Organum of Bacon, or the Essays of Locke; without, however, meaning to compare the French author with our two countrymen, either as a contributor to our stock of facts relating to the intellectual phænomena, or as the author of any important conclusion concerning the general laws to which they may be referred.” The excellent edition by M. Cousin, in which alone the entire works of Descartes can be found, is a homage that France has recently offered to his memory, and an important contribution to the studious both of metaphysical and mathematical philosophy. I have made use of no other, though it might be desirable for the inquirer to have the Latin original at his side, especially in those works which have not been seen in French by their author.
