Fundamental Philosophy, Vol. 2 (of 2)

61. Experience teaches that this communication exists, conformably to a law of the human mind, and that to contend against the law is to struggle against a truth attested by consciousness: to attempt to destroy it would be a rash undertaking, a kind of mental suicide. For this reason, the school of which we have just spoken, accepts the facts, such as internal experience presents them, and endeavors to explain them by indicating the points where the sensible and intellectual orders may come into communication without being destroyed or confounded.

62. The school that admits the existence of the two orders, the sensible and the intellectual, and at the same time admits the possibility and the reality of their reciprocal communication and influence, has, for its fundamental principle, that the origin of all cognition is in the senses, these being the exciting causes of intellectual activity, and a kind of laborers who supply it with materials, which it then combines in the manner necessary to raise the scientifical structure.

63. Thus far, Kant and the scholastics agree; but here they separate at a point of the greatest importance, and the result is that they pass on to conflicting consequences. The scholastics believed that there were in the understanding true ideas having true objects, and that they might discuss them, independently of the sensible order, with perfect security. They even admitted the principle that there can be nothing in the understanding which was not previously in the senses; but pretended, nevertheless, that there really was something in the understanding, which might conduce to the knowledge of the truth of immaterial, as well as of material things in themselves. The ideas of the purely intellectual order originate in the senses as movers of the intellectual activity; but this activity, by means of abstraction and other operations, forms to itself ideas of its own, by whose aid it may go beyond the sensible order in its search for truth.

64. In their explanation of the purely intellectual order, metaphysicians, both scholastics and anti-scholastics agree, so far as there is question of giving a real objective value to ideas, and of making them a sure means of discovering truth independently of sensible phenomena. However much these schools disagree as to the origin of ideas, they agree in all that relates to their reality and value.

65. Kant, at the same time that he admits the principle of the scholastics, that all our cognitions come from the senses, and recognizes with them the necessity of acknowledging a purely intellectual order, a series of conceptions different from sensible intuition, maintains that these conceptions are not pure cognitions, but empty forms, which of themselves mean nothing, teach the mind nothing, and cannot, in the least, aid us to know the reality of things. These conceptions mean nothing unless filled, so to speak, with sensible intuitions. If these intuitions are wanting, they correspond to nothing, and can be of none but a purely logical use; that is to say, the understanding will think upon and combine them, without, indeed, falling into contradiction, but also without ever coming to any conclusion.

"That the understanding," Kant says, "can never make a transcendental, but only an empirical use, either of its a priori principles, or of its conceptions, is a principle which, if known with conviction, leads to the most important consequences. The transcendental use of a conception in any principle, consists in referring it to things, in general, and in themselves; whilst the empirical use is in referring the conception to phenomena alone, that is, to the objects of a possible experience, by which we may easily see that this latter use is the only one that can stand. To every conception is necessary, first of all, a logical form of a conception in general, of the thought: and secondly, the possibility of subjecting to it an object, to which it may refer; but without this object it wants all sense, it contains nothing, although it may involve the logical function necessary to form a conception by means of certain data. The object cannot be given to a conception except in intuition; and although pure intuition may be a priori possible before the object, it cannot, however, receive its object, and consequently its objective value, otherwise than by the empirical intuition of which it is the form. All conceptions and with them all principles, although they be possible a priori, do, notwithstanding, refer to empirical intuitions, that is, to data of possible experience. Without this they have no objective value; they are nothing but a mere play, whether of the imagination or of the understanding, with the respective representations of the one or the other faculty.

"That the same is the case with all the categories and principles formed from them, is apparent from this, that we cannot really define a single one of them; that is to say, we cannot render the possibility of their object intelligible without attending to the conditions of sensibility, and consequently to the form of the appearances; conditions to which these categories must be confined as to their sole objects. If this condition be taken away, all meaning, that is, all relation to the object is destroyed, and by no example can we be made to conceive what is the proper meaning of these conceptions.

"If no account be made of all the conditions of sensibility which denote them (he is speaking of the categories) as conceptions of a possible empirical use, if they be taken to be conceptions of things in general, and consequently, of transcendental use, nothing remains to be done, so far as they are concerned, but to preserve the logical functions in judgments, as the condition of the possibility of the things themselves, without being able to show in what case, their application and their object, and consequently they themselves, may, in the pure understanding, and without the intervention of sensibility, have a meaning and an objective value.

"It incontestably follows from what has been said, that pure conceptions of the understanding can never have a transcendental use, but only an empirical use; and that the principles of the pure understanding do not refer to the objects of the senses, except when the senses are in relation with the general conditions of a possible experience; but never to things in general, without relation to the way in which we may perceive them."8

66. Thus Kant destroys all metaphysical science, and, involved in its deplorable ruins, perish the most fundamental, most precious, and most sacred ideas of the human mind. According to him, transcendental analysis makes us see that the understanding can never pass the limits of sensibility, the only limits within which objects are given to us in intuition. These principles which were regarded as eternal pillars of the scientific edifice sink into empty forms, into words without meaning, so soon as they rise from the sphere of sensibility.

Ontology, with its transcendental doctrines, avails not in the eyes of the German philosopher to explain the nature and origin of things. "These principles," he says, "are simply principles of the exposition of phenomena; and the proud name of an ontology which pretends to give an a priori, synthetic cognition of things, in a systematic doctrine, for example, the principle of causality, ought to be replaced by the modest denomination of simple analysis of the pure understanding."

67. It would be hard to find a more noxious doctrine. What is left to the human mind when all means of rising from the sensible sphere are taken away? To what is our understanding reduced, if its most fundamental ideas, and its noblest principles can teach nothing concerning the nature of things? If the corporeal world is for us nothing but a collection of sensible phenomena, beyond which we can know nothing, our cognitions have nothing real, they are all purely subjective; the soul lives on illusions, and vanishes with its imaginary creations, to which there is nothing to correspond in reality. Space is but a subjective form; time is but a subjective form; pure ideas are empty conceptions, and all in us is subjective. We know nothing of objects, we are totally ignorant of what is; we know only what appears. This is pure skepticism; assuredly it was not necessary to consume so much time in analytical investigations to get thus far. The doctrine of Kant presents no extravagance so outrageous, no error so hideous, as the works of Fichte, Schelling, and Hegel; but it contains the germ of the greatest extravagance, and of the most fatal errors. He has made a philosophical revolution, which some have incautiously deemed a progress; but doubtless they did not detect the skepticism it contains, which is the more dangerous, the more it is enveloped in analytical forms.

68. Notwithstanding the importance justly attached to the refutation of the German philosopher's errors, I do not deem it necessary to combat his doctrines step by step; this system of refutation labors under the serious objection that it gives little satisfaction to the reader, who seems to see one edifice torn down, but not replaced by another. I consider it more useful carefully to examine questions as they arise in the order of their subjects, to establish my opinion as best I can, and there to refute Kant's errors as I find them obstructing the march of truth. It is ordinarily very easy to say what a thing is not; but it is not so easy to say what it is; and it is not proper that the advocates of sound doctrine should be charged with impugning false doctrines, and not caring to expose their own. We believe that in these matters sound philosophy may be presented to the light of the day struggling against error, and that it ought not to rest satisfied with being the instrument of war to overthrow its adversary, but that it should aspire to found a noble and enduring edifice upon the very site the other occupied.

The minds of men are not satisfied with simple refutations; they desire to have a doctrine substituted in the place of the one impugned. Whoever impugns, denies; and the understanding is not satisfied with negations; it wants affirmation, for it cannot live without positive truth.

We have permitted ourselves this brief digression, which is indeed far from being useless; for at the sight of the transcendency of the German philosopher's errors I have recollected the necessity of careful, assiduous, and profound labor to oppose this deluge of errors which threatens to inundate the whole field of truth; and we could not do less than insist upon this point, and observe that it is not enough to tear down, but that it is also necessary to build up. Refutations will soon come; but let positive doctrines abound. It is not enough to cover the long line of frontiers where error makes its attacks, with light and active troops which may fall upon the enemy; it is necessary to found colonies, foci of cultivation and civilization, who will defend the country, at the same time that they make it flourish and prosper.

CHAPTER X.

SENSIBLE INTUITION

69. Intuition, properly so called, consists in the act of the soul by which it perceives an object that effects it: this the signification of the Latin word derived from the verb intueri, to see a thing which is present, indicates.

70. Intuition belongs only to perceptive powers, to those by which the subject affected distinguishes between its affection and the object causing it. We do not pretend to say that this must be a reflex distinction, but simply that the internal act must refer to an object. If we suppose a being to experience various affections, but to neither refer them to any object, nor reflect upon them itself; this being can never with propriety be said to have true intuition, for intuition seems to involve the exercise of an activity occupied with a present object. The object of intuition need not always be an external being; it may be an affection or action of the soul made objective by a reflex act.

71. The sensations which are with the greatest propriety called intuitive, are those of sight and touch; for, since it is impossible for us, when we perceive extension, to regard it as a purely subjective fact, the acts of seeing and feeling necessarily involve relation to an object. The other senses, although they may have a certain relation to extension, do not perceive it directly, so that were they to stand alone, they would partake more of the affective than of the intuitive; that is, the soul would be affected by the sensations, but would be under no necessity of referring them to external objects. If reflection made upon these sensations come to teach, as in effect it would teach that their cause is a being distinct from those that experience them, there would be no true intuition; not for the senses, because they would remain foreign to complex combinations; nor for the understanding, because it would then know the cause of the sensations, not by intuition, but by discursion.

72. We infer from this, that not every sensation is an intuition; and that the imaginary reproductions of past sensations, or the imaginary production of possible sensations, although repeatedly styled intuitions, are, since they do not refer to an object, unworthy of the name. We ought, nevertheless, to observe that the phenomena of purely internal sensibility do, perhaps, owe to the habit of reflection their non-reference to objects. Reflection perceives the difference of time, the more or less vividness of sensations, their greater or less constant connection, and also other circumstances; and it is enabled by these to distinguish between representations which do really refer to an object, such as external sensations, and those that have only a past or possible object, such as purely internal representations. Thus experience teaches us that the purely internal sensibility, wholly abandoned to itself, transfers whatever is presented to it to the external world, without the aid of reflection, and converts imaginary appearances into realities. This is verified in sleep, or even in our waking hours, when by some cerebral inversion the sensibility works by itself alone, and entirely free of reflection.

73. The reason why the sensibility left to itself, renders all its impressions objective, is to be looked for in the fact, that being a non-reflective faculty, it cannot distinguish between a purely internal affection, and one coming from without. Since comparison, however inconsiderable it may be, always implies reflection, sensibility does not compare. Hence it happens that when the subject does nothing but feel, it cannot appreciate the differences of sensations, by calculating the degrees of their vividness, nor ever perceive the existence or want of order and constancy in their connection.

The faculty of feeling is perfectly blind to all but its determinate object; whatever it does not discover in this so far as it is its object, does in no manner exist for it. We can now see why, when left to itself, it will render its impressions objective, and believe itself intuitive by converting simple appearances into realities.

74. It is worthy of notice, that of the sensitive faculties, some would always be intuitive, that is, would always refer to an external object, if reflection did not accompany them; whilst others would never be intuitive, not even if separated from reflection, or unaccompanied by those which are by their nature intuitive. To the former class belong the representative faculties, properly so called, that is, those which affect the sensitive subject by presenting to it a form, the real or apparent image of an object. Such are those of sight and of touch, which can neither exist nor be conceived without this representation. Other sensations, on the contrary, offer no form to the sensitive subject; they are simple affections of the subject, although they proceed from an external cause; if we refer them to objects, this we do by reflection; and when this warns us that we have in attributing to the object not only the principle of causality, but also the sensation in itself, carried the reference too far, we easily recognize the illusion, and lay it aside. This does not occur in representative sensations; no one, no matter how great efforts he may make, will ever be able to persuade himself that beyond himself there is nothing real, nothing resembling the sensible representation in which objects are presented as extended.

75. When we say that some sensations would not be intuitive were they not accompanied by reflection, we do not mean to say that man refers them to an object, after explicit reflection, for we cannot forget what we have already said when explaining at length the instinctive way in which our faculties develop themselves prior to all reflection, in their relations with the corporeal world; but only that no necessary relation to an object as represented can be discovered in these sensations considered in themselves, and in perfect isolation; and that, probably, if a confused reflection be not mingled with the instinct which makes us render them objective, there at least enters some influence of other sensations, which are by their proper object representative.

CHAPTER XI.

TWO COGNITIONS: INTUITIVE AND DISCURSIVE

76. Now that I have explained sensible, I pass to intellectual intuition. There are two modes of knowing; the one is intuitive, the other discursive. Intuitive cognition is that in which the object is presented to the understanding, such as it is, and upon which the perceptive faculty has to exercise no function but that of contemplation; it is therefore called intuition, from intueri, to see.

77. This intuition may take place in two ways. It may either present the object itself to the perceptive faculty, and unite them without any intermediacy; or by the intervention of an idea or representation, capable of putting the perceptive faculty in action, so that it may, without the necessity of combination, see the object in this representation. The first requires the object perceived to be intelligible by itself, since otherwise there could be no union of the object understood with the subject understanding; the second needs a representation to supply the place of the object, and consequently it is not indispensable that this should be immediately intelligible.9

78. Discursive cognition is that in which the understanding does not have the object itself present, but forms it itself, so to speak, by uniting in one whole conception several partial conceptions, whose connection in one subject it has found out by ratiocination.

In order to render more apparent the difference between intuitive and discursive cognition, I will illustrate it by an example. "We see a man; his physiognomy is presented to us, such as it is; no combinations are necessary, none could possibly make him appear differently. We see his characteristic features, such as they are; but the collection of them is not a thing produced by our combinations; it is an object given to the perceptive faculty which has nothing to do but to perceive it." When an object is offered to our understanding in this way, the cognition we have of it will be intuitive.

We have said that the object of intellectual intuition may be united immediately to the perceptive faculty, or that it may be presented to it by a medium which acts the part of the object. Keeping in view the same example, we might say that these two classes of intuitions correspond to those of the man seen by himself, or in his portrait. There would be in both cases intuition of his physiognomy, but no combination would be necessary, and none could possibly form it.

But suppose some one to tell us of a person whom we have never seen, and whose portrait cannot be shown to us. He would be obliged, in order to give us an idea of his physiognomy, to enumerate one by one his characteristic features, by the union of which we shall form an idea of the likeness he has just described. To this imaginary representation may be compared discursive cognition, by which, although we do not see the object, we in some sense construct it, as it were, from the assemblage of those ideas which we have by means of discursion interlinked, and formed into one whole conception representing the object.

79. Kant, in his Critic of Pure Reason, speaks repeatedly of intuitive and discursive cognition; but he does not explain with perfect clearness the distinctive characteristics of these two classes of cognition. Let it not, however, be supposed that the discovery of these two ways of perceiving is due to the German philosopher. Many ages before him, the theologians had known them; nor could it be otherwise, since the distinction between intuition and discursion is intimately connected with one of the fundamental dogmas of Christianity.

It is well known that our religion admits the possibility and reality of a true cognition of God, even in this life. The sacred text tells us that we may know God by his works; that the invisible things of God are manifested to us by his visible creatures; that the heavens narrate his glory, and the firmament announces the works of his hands; that they who have thus known God are inexcusable, because they have not glorified him as they ought; but this same religion teaches us that the Blessed, in the life to come, will know him in a very different manner, will see him as he is, face to face. It was Christianity then that marked the difference between intuitive and discursive cognitions, between the cognition by which the understanding, proceeding from effects to their cause, and uniting in it the ideas of wisdom, omnipotence, goodness, holiness, and infinite perfection, rises to God; and the cognition in which the mind does not need to advance, drawing its conclusions by aid of discursion, from various conceptions, in order to force from them an idea of God, in which the Infinite Being will offer himself clearly to the eyes of the mind, not in a conception elaborated by reason, nor under the sublime mysteries of faith, but such as he is, in himself, as an object given immediately to the perceptive faculty, not as an object discovered by the force of discursion, or presented under august shadows. And here we find another proof of the great profoundness hidden under the dogmas of the Christian religion. This distinction is to be met with in the catechism, and yet who would have suspected that religion had taught us a doctrine so important to ideological science? If the child be asked, who is God, he replies by enumerating his perfections, and showing thereby that he knows him. If you ask this same child, to what end man has been created, he will answer, to see God, etc.

Here again is the distinction between discursive cognition, or by conceptions, and intuitive cognitions; with the former one is said, simply to know, with the latter to see.

CHAPTER XII.

THE SENSISM OF KANT

80. Kant maintained that while in the present life, we have only sensible intuition; and he considers the possibility of a purely intellectual intuition, whether for our own or for other minds doubtful. But as we have seen elsewhere (ch. IX.) that he does not attribute any value to conceptions separated from intuition, we infer that he is, notwithstanding his long dissertations upon the pure understanding, a confirmed sensist; and that the authors of the Critic of Pure Reason, and of the Treatise on Sensations, differ much less than at first sight might be supposed. If our mind has no other intuition than the sensible, and the conceptions of the pure understanding are, if they do not include some one of these intuitions, nothing but empty forms; if when we abstract these intuitions, there are in the understanding only purely logical functions, which mean nothing, and in no sense deserve to be called cognitions; it follows that there is in our mind nothing but sensations, which may be methodically distributed in conceptions, as if packed away in a kind of hut, where they are registered and preserved. According to this philosopher, the understanding is reduced so low, that Condillac himself might admit it.

81. Indeed, in the system of sensations transformed, the mind is supposed to possess a transforming force, since otherwise, it would be impossible to explain all ideological phenomena by mere sensation, and the very title of the system would be a contradiction. This being so, would any sensistic scruple have prevented Condillac from admitting the synthesis of the imagination, the relations of all sensible intuitions to the unity of apperception, and finally, a variety of logical functions, to classify and compare sensible intuitions? So far is this from being the case, it would seem that the root of all these doctrines might be found in the system of the French philosopher, whose fundamental principles, when summed up, amount to this: that nothing can be seen in the mind besides sensations; but he does not therefore deny it a force capable of transforming, classifying, and generalizing them.
