Whether, then, we start with the soul as first principle or with God, we can never by logical deduction arrive at creation, or be able to assert any existence as distinguishable from the Divine Being. Neither can be taken exclusively as the primum philosophicum, and exclusive ontology is as faulty and as fatal in its consequences as exclusive psychology. The fact is, we can neither doubt the being of God nor our own personal existence; for both are equally essential and indestructible elements of thought, given in the primitive intuition, though being is logically prior to existence, and our primum philosophicum must include both.
But the soul is given in the intuition as contingent, and being is given as necessary. The contingent cannot exist any more than it can be thought without the necessary. It then depends on the necessary, and can exist only as created and upheld by it. The real principle, or primum philosophicum, is then, as has been amply shown in the essays on The Problems of the Age, the ideal formula, Ens creat existentias, or Being creates existences. This presents the ontological principle and the psychological not in juxtaposition merely, but in their real and true relation. This formula enables us to avoid alike pantheism, atheism, idealism, and materialism, and to conform in principle our philosophy to the real order of things and the Catholic faith. But it is only in principle, for Gioberti himself calls the formula ideal. It does not, after all, give us any science of actual existences, or itself furnish its own scientific explication and application. Apply to it the method of Descartes, and lay it down that everything is to be doubted till proved, and we are not much in advance of Cartesianism. We know God is, we know things exist, and God has created or creates them; but we do not know by knowing the formula what God is, what things do or do not exist. It gives us the principles of science, but not the sciences; the law which governs the explication of facts, not the facts themselves. We cannot deduce, after the manner of the geometricians, any actual existence or fact from the formula, nor any of the sciences. There is an empirical element in all the sciences, and none of them can be constructed by logical deduction even from a true ideal formula, and to deny everything not logically deducible from it would leave us in the purely ideal, and practically very little better off than Descartes himself left us. The Cartesian method based on doubt, then, whether we start with an incomplete or a complete ideal formula, can never answer the purpose of the philosopher, or enable us to construct a concrete philosophy that includes the whole body of truth and all the scientific facts of the universe.
We do not pretend that philosophy must embrace all the knowable, omne scibile, in detail; it suffices that it does so in principle. No doubt the ideal formula does this, as in fact always has done the philosophy that has obtained in the Catholic schools. But though the ideas expressed in the ideal formula are intuitive, the constitution of the mind, and basis of all intelligence, and are really asserted in every thought, we very much doubt if they could ever have been reduced to the formula given by Gioberti if men had never received a divine revelation from God, or if they had been left without any positive instruction from their Creator. We are as far as any one can be from building science on faith; but we so far agree with the traditionalists as to hold that revelation is necessary to the full development of reason and its perfect mastery of itself. One great objection to the Cartesian doubt or method is, that it detaches philosophy from theology, and assumes that it can be erected into an independent science sufficient for itself without any aid from supernatural revelation, and free from all allegiance to it. This had never been done nor attempted by any Christian school or even non-Christian school prior to Descartes, unless the pretension of Pomponatius and some others, that things may be theologically true yet philosophically false, and who were promptly condemned by Leo X., be understood as an attempt in that direction. The great fathers of the church and the mediaeval doctors always recognized the synthesis of reason and revelation; and, while they gave to each its part, they seem never to have dreamed of separating them, and of cultivating either as independent of the other; yet they have given us a philosophy which, if not free from all defects, is superior, under the point of view of reason alone, to anything that has elsewhere ever been given under that name. He who would construct a philosophy that can stand the test even of reason must borrow largely from St. Athanasius, St. Augustine, St. Gregory the Great, St. Thomas, St. Buonaventura, and the later scholastics.
It is also an objection to the Cartesian doubt that it is not only a complete rupture with revealed theology, but also with tradition, and is an attempt to break the continuity of the life of the race, and to sever the future of humanity from its past. We are among those who regard the catholic beliefs and traditions of mankind as integral elements in the life of the race itself, and indispensable to its continuous progress. The future always has its germ in the past, and a beginning de novo for the individual as for society is alike impossible and undesirable. The Cartesian doubt overlooks this, and requires the individual to disgarnish his mind of every relic and memorial of the past, of everything furnished by his parents and teachers, or the wisdom of ages, and after having become absolutely naked and empty, and made himself as ignorant and impotent as the new-born babe, to receive nothing till he, without experience, without instruction, has by his own unaided powers tested its truth. As reasonable would it be for the new-born infant to refuse the milk from its mother's breast, till it had by the exercise of its faculties settled the question of its wholesomeness.
We object, finally, that it tends to destroy all respect for authority, all reverence for tradition, all regard for the learning and science of other ages and other men, and to puff up the individual with an overweening self-conceit, and sense of his own sufficiency for himself. It renders all education and instruction useless and an impertinence. It tends to crush the social element of our nature, and to create a pure individualism, no less repugnant to government and society than to religion and the divine order, according to which all men are made mutually dependent, one on another. Doubtless, Descartes only developed and gave expression to tendencies which were in his time beginning to be active and strong; but the experience of the civilized world only historically verifies their destructive, anti-philosophical, anti-religious, and anti-social character. Yet his method is still, in substance if not in form, very extensively accepted and followed, as the example of The Churchman itself proves.
We do not by any means believe that Descartes had any suspicion of the real character of his philosophic enterprise. We are far from agreeing with Gioberti that he was a disguised Protestant designedly laboring to complete the work undertaken by Luther. We doubt not that he really accepted the church, as he always professed to do, though most likely he was far enough from being a fervent Catholic; but he was bred a soldier, not a philosopher or a theologian; and though he may have been, and we believe he was for his time, a great mathematician and a respectable physicist, he was always a poor theologian, and a still poorer metaphysician. His natural ability was no doubt worthy of admiration, but he had no genius for metaphysics, and his ignorance of the profounder philosophy of antiquity and of the mediaeval doctors was almost marvellous. He owed in his own day his popularity to the fact that he discoursed on philosophy in the language of the world, free from the stiff formulas, the barbarous locutions, and the dry technicalities of the schools. He owed much to the merits of his style, but still more to the fact that he wrote in the vernacular instead of the Latin tongue, then unusual with writers of philosophical treatises, and non-professional men and court-bred ladies could read him and fancy they understood philosophy. His works were "philosophy-made-easy," and he soon became the vogue in France, and France gives the fashion to the world. But it would be difficult to name a writer who has exerted in almost every direction an equally disastrous influence on modern thought and civilization; not that his intentions were bad, but that his ignorance and presumption were great.
The Cartesian method has no doubt favored that lawless and independent spirit which we see throughout modern society, and which is manifested in those Jacobin revolutions which have struck alike at ecclesiastical and political authority, and at times threatened the civilized world with a new barbarian invasion; but the evil resulting from that method which is now the most to be deplored is the arrogant and independent tone assumed by modern science, and its insolence toward the sacred dogmas of faith. Descartes detached philosophy, and with it all the sciences, from faith, and declared them independent of revelation. It is especially for this that Cousin praises him. But modern so-called science is not contented even with independence; it aspires to dominate and subject faith to itself, or to set up its own conclusions as the infallible test of truth. It makes certain inductions from a very partial survey of facts, concocts certain geological, physiological, ethnological, and philological theories at war with the dogmas of faith, and says with sublime insolence that therefore faith must give way, for science has demonstrated its falsity! If the church condemns its unsupported conclusions, there is forthwith a deafening clamor raised that the church is hostile to science, and denies the freedom of thought and the inalienable rights of the mind! The Churchman sees this, and has written the very article from which we have made our extract to show its injustice; but with what success can it hope to do it, after beginning by approving the Cartesian method and conceding modern science, in principle, all it asks?
We have said and shown over and over again that the church does not condemn science. Facts, no matter of what order, if facts, never do and never can come in collision with her teaching, nor can their real scientific explanations ever conflict with revelation or her dogmas. The church interferes not with the speculations or the theories of the so-called savans, however crude, extravagant, or absurd they may be, unless they put forth conclusions under the name of science which militate against the Christian faith. If they do that, she condemns their conclusions so far as repugnant to that faith. This supervision of the labors of savans she claims and exercises for the protection of her children, and it is as much in the interest of science as of faith that she should do so. If we were to believe what men counted eminent in science tell us, there is not a single Christian dogma which science has not exploded; yet, though modern investigations and discoveries may have exploded several scientific theories once taught in the schools and accepted by Catholics, we speak advisedly when we say science has not exploded a single dogma of the church, or a single proposition of faith she has ever taught. No doubt, many pretendedly scientific conclusions have been drawn and are drawn daily that impugn the faith; but science has not yet confirmed one of them, and we want no better proof that it never will confirm them than the bare fact that they contradict the faith the church believes and teaches. They can all be scientifically refuted, and probably one day will be, but not by the people at large, the simple and unlettered; and therefore it is necessary that the church from time to time should exert her authority to condemn them, and put the faithful on their guard against them. This is no assumption to the injury of science, for in condemning them she seeks only to save the revealed truth which they impugn. It is necessary, also, that men should understand that in science as well as in faith they are not independent of God, and are bound by his word wherever or whatever it speaks. Descartes taught the world to deny this and even God himself till scientifically proved, and hence the pains we have taken to refute his method, to show its unscientific character, and to indicate some of the fatal consequences of adopting it.
We know very well that Bossuet and Fdénélon are frequently classed with the disciples of Descartes, but these men were learned men and great theologians, and they followed Descartes only where he coincided with the general current of Catholic philosophy. Either was a far profounder philosopher than Descartes ever could have been, and neither adopted his method. The same may be said of other eminent men, sometimes called Cartesians. The French place a certain national pride in upholding Descartes, and pardon much to the sophist in consideration of the Frenchman; but this consideration cannot weigh with us any more than it did with the Italian Jesuit, the eminent Father Tapparelli, we believe, who a few years since, in some remarkable papers in La Civiltá Cattolica, gave a most masterly refutation of Descartes's psychological method. Truth is of no nation, and a national philosophy is no more commendable than a national theology, or a national church. It is no doubt to the credit of a nation to have produced a really great philosopher, but it adds nothing to its glory to attempt to make pass for a great philosopher a man who was in reality only a shallow sophist. It was one of the objectionable features in the late M. Cousin that he sought to avail himself of the national prejudices of his countrymen, and to make his system pass for French or the product of French genius. The English are in this respect not less national than the French, and Bacon owes his principal credit with them to the fact that he was a true Englishman. All real philosophy, like all truth, is catholic, not national.
In regard to the scepticism The Churchman deems so essential in the investigation of truth, we have already remarked that a sceptical disposition is the worst possible preparation for that investigation. He who would find truth must open his heart to it, as the sunflower opens her bosom to the sun, and turns her face toward it in whatever quarter of the heavens it may be. Those who, like The Churchman, know not the truth in its unity and catholicity, and substitute opinion for faith, will do well so far to doubt their opinions as to be able thoroughly to investigate them, and ascertain if they have any solid foundation. There are reasons enough why they should distrust their own opinions, and see if the truth is not really where the great majority of the civilized world for ages has told them it is to be found. They ought to doubt, for they have reason to doubt, not of every thing, not of God, not of truth, but of their own opinions, which they know are not science nor faith, and therefore may be false. Scientific men should doubt not science, nor the possibility of science, but their theories, hypotheses, and conjectures till they have proved them; and this all the same whether their theories, hypotheses, and conjectures are taken from the schools or are of their own concoction. But this is something very different from presenting to the world or to one's self the being of God, the creation, the immortality of the soul, and the mysteries of faith as opinions or as theories to be doubted till proven after the manner of geometricians. These are great truths which cannot be reasonably doubted; and, if we find people doubting them, we must, in the best way we can, convince them that their doubts are unreasonable. The believer need not doubt or deny them in order to investigate the grounds of his faith, and to be able to give a reason for the hope that is in him. We advance in the knowledge of truth by means of the truth we have; and the believer is much better fitted for the investigation of truth than the unbeliever, for he knows much better the points that need to be proved, and has his mind and heart in a more normal condition, more in harmony with the real order of things, and is more able to see and recognize truth. But this investigation is not necessary to justify faith in the believer. It is necessary only that the believer may the better comprehend faith in its relations with the general system of things, of which he forms a part, and the more readily meet the objections, doubts, and difficulties of unbelievers. But all cannot enter into this investigation, and master the whole field of theology, philosophy, and the sciences, and those who have not the leisure, the opportunity, and ability to do it, ought not to attempt it. The worst possible service we can render mankind is to teach them that their faith is unreasonable, or that they should hold themselves in suspense till they have done it, each for himself. They who can make the investigation for themselves are comparatively few; and shall no man venture to believe in God and immortality till he has made it? What, then, would become of the great body of the people, the poorer and more numerous classes, who must be almost wholly occupied with procuring the means of subsistence? If the tender mercies of God were no greater than those of the Cartesian philosophers and our Episcopalian Churchman, the poor, the unlettered, the simple, the feeble of intellect would be obliged to live without any rule of duty, without God in the world, or hope in the world to come. For them the guidance and consolations of religion would alike be wanting.
