Such are the philosophic schools in the presence of which the nineteenth century is placed.
We are compelled to avow, that none of these, to our eyes, contains the entire truth. It has been demonstrated that a considerable part of knowledge escapes sensation, and we think that sentiment is a basis neither sufficiently firm, nor sufficiently broad, to support all human science. We are, therefore, rather the adversary than the partisan of the school of Locke and Condillac, and of that of Hutcheson and Smith. Are we on that account the disciple of Reid and Kant? Yes, certainly, we declare our preference for the direction impressed upon philosophy by these two great men. We regard Reid as common sense itself, and we believe that we thus eulogize him in a manner that would touch him most. Common sense is to us the only legitimate point of departure, and the constant and inviolable rule of science. Reid never errs; his method is true, his general principles are incontestable, but we will willingly say to this irreproachable genius,—Sapere aude. Kant is far from being as sure a guide as Reid. Both excel in analysis; but Reid stops there, and Kant builds upon analysis a system irreconcilable with it. He elevates reason above sensation and sentiment; he shows with great skill how reason produces by itself, and by the laws attached to its exercise, nearly all human knowledge; there is only one misfortune, which is that all this fine edifice is destitute of reality. Dogmatical in analysis, Kant is skeptical in his conclusions. His skepticism is the most learned, most moral, that ever existed; but, in fine, it is always skepticism. This is saying plainly enough that we are far from belonging to the school of the philosopher of Kœnigsberg.
In general, in the history of philosophy, we are in favor of systems that are themselves in favor of reason. Accordingly, in antiquity, we side with Plato against his adversaries; among the moderns, with Descartes against Locke, with Reid against Hume, with Kant against both Condillac and Smith. But while we acknowledge reason as a power superior to sensation and sentiment, as being, par excellence, the faculty of every kind of knowledge, the faculty of the true, the faculty of the beautiful, the faculty of the good, we are persuaded that reason cannot be developed without conditions that are foreign to it, cannot suffice for the government of man without the aid of another power: that power which is not reason, which reason cannot do without, is sentiment; those conditions, without which reason cannot be developed, are the senses. It is seen what for us is the importance of sensation and sentiment: how, consequently, it is impossible for us absolutely to condemn either the philosophy of sensation, or, much more, that of sentiment.
Such are the very simple foundations of our eclecticism. It is not in us the fruit of a desire for innovation, and for making ourself a place apart among the historians of philosophy; no, it is philosophy itself that imposes on us our historical views. It is not our fault if God has made the human soul larger than all systems, and we also aver that we are also much rejoiced that all systems are not absurd. Without giving the lie to the most certain facts signalized and established by ourself, it was indeed necessary, on finding them scattered in the history of philosophy, to recognize and respect them, and if the history of philosophy, thus considered, no longer appeared a mass of senseless systems, a chaos, without light, and without issue; if, on the contrary, it became, in some sort, a living philosophy, that was, it should seem, a progress on which one might felicitate himself, one of the most fortunate conquests of the nineteenth century, the very triumphing of the philosophic spirit.
We have, therefore, no doubt in regard to the excellence of the enterprise; the whole question for us is in the execution. Let us see, let us compare what we have done with what we have wished to do.
Let us ask, in the first place, whether we have been just towards that great philosophy represented in antiquity by Aristotle, whose best model among the moderns is the wise author of the Essay on the Human Understanding.
There is in the philosophy of sensation what is true and what is false. The false is the pretension of explaining all human knowledge by the acquisitions of the senses; this pretension is the system itself; we reject it, and the system with it. The true is that sensibility, considered in its external and visible organs, and in its internal organs, the invisible seats of the vital functions, is the indispensable condition of the development of all our faculties, not only of the faculties that evidently pertain to sensibility, but of those that seem to be most remote from it. This true side of sensualism we have everywhere recognized and elucidated in metaphysics, æsthetics, ethics, and theodicea.
For us, theodicea, ethics, æsthetics, metaphysics, rest on psychology, and the first principle of our psychology is that the condition of all exercise of mind and soul is an impression made on our organs, and a movement of the vital functions.
Man is not a pure spirit; he has a body which is for the spirit sometimes an obstacle, sometimes a means, always an inseparable companion. The senses are not, as Plato and Malebranche have too often said, a prison for the soul, but much rather windows looking out upon nature, through which the soul communicates with the universe. There is an entire part of Locke's polemic against the theories of innate ideas that is to our eyes perfectly true. We are the first to invoke experience in philosophy. Experience saves philosophy from hypothesis, from abstraction, from the exclusively deductive method, that is to say, from the geometrical method. It is on account of having abandoned the solid ground of experience, that Spinoza, attaching himself to certain sides of Cartesianism,[267] and closing his eyes to all the others, forgetting its method, its essential character, and its most certain principles, reared a hypothetical system, or made from an arbitrary definition spring with the last degree of rigor a whole series of deductions, which have nothing to do with reality. It is also on account of having exchanged experience for a systematic analysis, that Condillac, an unfaithful disciple of Locke, undertook to draw from a single fact, and from an ill-observed fact, all knowledge, by the aid of a series of verbal transformations, whose last result is a nominalism, like that of the later scholastics. Experience does not contain all science, but it furnishes the conditions of all science. Space is nothing for us without visible and tangible bodies that occupy it, time is nothing without the succession of events, cause without its effects, substance without its modes, law without the phenomena that it rules.[268] Reason would reveal to us no universal and necessary truth, if consciousness and the senses did not suggest to us particular and contingent notions. In æsthetics, while severely distinguishing between the beautiful and the agreeable, we have shown that the agreeable is the constant accompaniment of the beautiful,[269] and that if art has for its supreme law the expression of the ideal, it must express it under an animated and living form which puts it in relation with our senses, with our imagination, above all, with our heart. In ethics, if we have placed Kant and stoicism far above epicureanism and Helvetius, we have guarded ourselves against an insensibility and an asceticism which are contrary to human nature. We have given to reason neither the duty nor the right to smother the natural passions, but to rule them; we have not wished to wrest from the soul the instinct of happiness, without which life would not be supportable for a day, nor society for an hour; we have proposed to enlighten this instinct, to show it the concealed but real harmony which it sustains with virtue, and to open to it infinite prospects.[270]
With these empirical elements, idealism is guarded from that mystical infatuation which, little by little, gains and seizes it when it is wholly alone, and brings it into discredit with sound and severe minds. In our works—and why should we not say it?—we have often presented the thought of Locke, whom we regard as one of the best and most sensible men that ever lived. He is among those secret and illustrious advisers with whom we support our weakness. More than one happy thought we owe to him; and we often ask ourself whether investigations directed with the circumspect method which we try to carry into ours, would not have been accepted by his sincerity and wisdom. Locke is for us the true representative, the most original, and altogether the most temperate of the empirical school. Tied to a system, he still preserves a rare spirit of liberty,—under the name of reflection he admits another source of knowledge than sensation; and this concession to common sense is very important. Condillac, by rejecting this concession, carried to extremes and spoiled the doctrine of Locke, and made of it a narrow, exclusive, entirely false system,—sensualism, to speak properly. Condillac works upon chimeras reduced to signs, with which he sports at his ease. We seek in vain in his writings, especially in the last, some trace of human nature. One truly believes himself to be in the realm of shades, per inania regna.[271] The Essay on the Human Understanding produces the opposite impression. Locke is a disciple of Descartes, whom the excesses of Malebranche have thrown to an opposite excess: he is one of the founders of psychology, he is one of the finest and most profound connoisseurs of human nature, and his doctrine, somewhat unsteady but always moderate, is worthy of having a place in a true eclecticism.[272]
