Part 6 (2/2)

necessary mathematically measurable physical forces, he thought the sun and planets to have consolidated, and to have a.s.sumed the motions in which they proceed according to the teachings of Copernicus and Kepler. Kant thus believed he had proven, through a great discovery of his own, the fruitfulness of Spinoza's mode of thought, according to which everything happens with strict, mathematical necessity. He was so convinced of this fruitfulness that in the above- mentioned work he went so far as to exclaim, ”Give me matter, and I will build you a universe!” The absolute certainty of all mathematical truths was so firmly established for him that he maintains in his Basic Principles of Natural Science that a science in the proper sense of the word is only one in which the application of mathematics is possible. If Hume were right, it would be out of the question to a.s.sume such a certainty for the knowledge of mathematical natural science, for, in that case, this knowledge would consist of nothing but thought habits that man had developed because he had seen the course of the world along certain lines. But there would not be the slightest guaranty that these thought habits had anything to do with the law-ordered connection of the things of the world. From his presupposition Hume draws the conclusion: The scenes of the universe are continually s.h.i.+fting, and one object follows another in an uninterrupted succession, but the power of force which actuates the whole machine is entirely concealed from us and never discovers itself in any of the sensible qualities of body. . . . . (Enquiry Concerning Human Understanding, Sec. VII, part 1.) If we then place the world conception of Spinoza into the light of Hume's view, we must say, ”In accordance with the perceived course of the processes of the world, man has formed the habit of thinking these processes in a necessary, law-ordered connection, but he is not ent.i.tled to maintain that

this 'connection' is anything but a mere thought habit.” Now if this were the case, then it would be a mere deception of the human reason to imagine that it could, through itself, gain any insight into the nature of the world, and Hume could not be contradicted when he says about every world conception that is gained out of pure reason, ”Throw it into the fire, for it is nothing but deception and illusion.”

Kant could not possibly adopt this conclusion of Hume as his own. For him, the certainty of the knowledge of mathematical natural science was irrevocably established. He would not allow this certainty to be touched but was unable to deny that Hume was justified in saying that we gain all knowledge about real things only by observing them and by forming for ourselves thoughts about their connection that are based on this observation. If a law-ordered connection is inherent in things, then we must also extract this connection out of them, but what we really derive from the things is such that we know no more about it than that it has been so up to the present time. We do not know, however, whether such a connection is really so linked up with the nature of things that it cannot change in any moment. If we form for ourselves today a world conception based on our observations, events can happen tomorrow that compel us to form an entirely different one. If we received all our knowledge from things, there would be no certainty. Mathematics and natural sciences are a proof of this. That the world does not give its knowledge to the human mind was a view Kant was ready to adopt from Hume. That this knowledge does not contain certainty and truth, however, is a conclusion he was not willing to draw. Thus, Kant was confronted with the question that disturbed him deeply: How is it possible that man is in possession of true and certain knowledge and that he is, nevertheless, incapable of knowing anything of the reality of the world in itself?

Kant found an answer that saved the truth and certainty of human knowledge by sacrificing human insight into the grounds of the world. Our reason could never claim certainty about anything in a world lying spread out around us so that we would be affected by it through observation only.

Therefore, our world can only be one that is constructed by ourselves: A world that lies within the limits of our minds.

What is going on outside myself as a stone falls and causes a hole in the ground, I do not know. The law of this entire process is enacted within me, and it can proceed within me only in accordance with demands of my own mental organization. The nature of my mind requires that every effect should have a cause and that two times two is four. It is in accordance with this nature that the mind constructs a world for itself. No matter how the world outside ourselves might be constructed, today's world may not coincide in even a single trait with that of yesterday. This can never concern us for our mind produces its own world according to its own laws. As long as the human mind remains unchanged, it will proceed in the same way in the construction of the world. Mathematics and natural science do not contain the laws of the external world but those of our mental organization. It is, therefore, only necessary to investigate this organization if we want to know what is unconditionally true. ”Reason does not derive its laws from nature but prescribes them to nature.” Kant sums up his conviction in this sentence, but the mind does not produce its inner world without an impetus or impression from without. When I perceive the color red, the perception, ”red,” is, to be sure, a state, a process within me, but it is necessary for me to have an occasion to perceive ”red.” There are, therefore, ”things in themselves,” but we know nothing about them but the fact that they exist. Everything we observe belongs to the appearances within us. Therefore, in order to save the certainty of the mathematical and natural scientific truths, Kant has taken the whole world of observation in the

human mind. In doing so, however, he has raised insurmountable barriers to the faculty of knowledge, for everything that we can know refers merely to processes within ourselves, to appearances or phenomena, not to things in themselves, as Kant expresses it. But the objects of the highest questions of reason - G.o.d, Freedom and Immortality - can never become phenomena. We see the appearances within ourselves; whether or not these have their origin in a divine being we cannot know. We can observe our own psychic conditions, but these are also only phenomena. Whether or not there is a free immortal soul behind them remains concealed to our knowledge. About the ”things in themselves,”

our knowledge cannot produce any statement. It cannot determine whether the ideas concerning these ”things in themselves” are true or false. If they are announced to us from another direction, there is no objection to a.s.sume their existence, but a knowledge concerning them is impossible for us. There is only one access to these highest truths. This access is given in the voice of duty, which speaks within us emphatically and distinctly, ”You are morally obliged to do this and that.” This ”Categorical Imperative” imposes on us an obligation we are incapable of avoiding. But how could we comply with this obligation if we were not in the possession of a free will? We are, to be sure, incapable of knowledge concerning this quality of our soul, but we must believe that it is free in order to be capable of following its inner voice of duty. Concerning this freedom, we have, therefore, no certainty of knowledge as we possess it with respect to the objects of mathematics and natural science, but we have moral certainty for it instead. The observance of the categorical imperative leads to virtue. It is only through virtue that man can arrive at his destination. He becomes worthy of happiness. Without this possibility his virtue would be void of meaning and significance. In order that virtue may result from happiness, it is mandatory that a being exists who secures this

happiness as an effect of virtue. This can only be an intelligent being, determining the highest value of things: G.o.d. Through the existence of virtue, its effect is guaranteed, and through this guarantee, in turn, the existence of G.o.d. Because man is a sensual being and cannot obtain perfect happiness in this imperfect world, his existence must transcend this sensual existence; that is to say, the soul must be immortal. The very thing about which we are denied possible knowledge is, therefore, magically produced by Kant out of the moral belief in the voice of duty. It was respect for the feeling of duty that restored a real world for Kant when, under the influence of Hume, the observable world withered away into a mere inner world. This respect for duty is beautifully expressed in his Critique of Practical Reason: Duty! Thou sublime, great name that containest nothing pleasurable to bid for our favor, but demandest submission, . .

. proclaiming a law in the presence of which all inclinations are silenced although they may secretly offer resistance. . . .

That the highest truths are not truths of knowledge but moral truths is what Kant considered as his discovery. Man has to renounce all insight into a supersensible world, but from his moral nature springs a compensation for this knowledge. No wonder Kant sees the highest demand on man in the unconditional surrender to duty. If it were not for duty to open a vista for him beyond the sensual world, man would be enclosed for his whole life in the world of the senses. No matter, therefore, what the sensual world demands; it has to give way before the peremptory claims of duty, and the sensual world cannot, out of its own initiative, agree with duty. Its own inclination is directed toward the agreeable, toward pleasure. These aims have to be opposed by duty in order to enable man to reach his destination. What man does for his pleasure is not virtuous; virtue is only what he does in selfless devotion to duty. Submit your desires to duty; this is

the rigorous task that is taught by Kant's moral philosophy.

Do not allow your will to be directed toward what satisfies you in your egotism, but so act that the principles of your action can become those of all men. In surrendering to the moral law, man attains his perfection. The belief that this moral law has its being above all other events of the world and is made real within the world by a divine being is, in Kant's opinion, true religion. It springs from the moral life. Man is to be good, not because of his belief in a G.o.d whose will demands the good; he is to be good only because of his feeling for duty. He is to believe in G.o.d, however, because duty without G.o.d would be meaningless. This is religion within the Limits of Mere Reason. It is thus that Kant ent.i.tles his book on religious world conception.

The course that the development of the natural sciences took since they began to flourish has produced in many people the feeling that every element that does not carry the character of strict necessity should be eliminated from our thought picture of nature. Kant had this feeling also. In his Natural History of the Heavens, he had even outlined such a picture for a certain realm of nature that was in accordance with this feeling. In a thought picture of this kind, there is no place for the conception of the self-conscious ego that the man of the eighteenth century felt necessary. The Platonic and the Aristotelian thought could be considered as the revelation of nature in the form in which that idea was accepted in the earlier age, and as that of the human soul as well. In thought life, nature and the soul met. From the picture of nature as it seems to be demanded by modern science, nothing leads to the conception of the self-conscious soul. Kant had the feeling that the conception of nature offered nothing to him on which he could base the certainty of self-consciousness. This certainty had to be created for the modern age had presented the self-conscious ego as a fact. The possibility had to be

created to acknowledge this fact, but everything that can be recognized as knowledge by our understanding is devoured by the conception of nature. Thus, Kant feels himself compelled to provide for the self-conscious ego as well as for the spiritual world connected with it, something that is not knowledge but nevertheless supplies certainty.

Kant established selfless devotion to the voice of the spirit as the foundation of moral life. In the realm of virtuous action, such a devotion is not compatible with a surrender to the sensual world. There is, however, a field in which the sensual is elevated in such a way that it appears as the immediate expression of the spirit. That is the field of beauty and art. In our ordinary life we want the sensual because it excites our desire, our self-seeking interest. We desire what gives us pleasure, but it is also possible to take a selfless interest in an object. We can look at it in admiration, filled by a heavenly delight and this delight can be quite independent of the possession of the thing. Whether or not I should like to own a beautiful house that I pa.s.s has nothing to do with the ”disinterested pleasure” that I may take in its beauty. If I eliminate all desire from my feeling, there may still be found as a remaining element a pleasure that is clearly and exclusively linked to the beautiful work of art. A pleasure of this kind is an ”esthetic pleasure.” The beautiful is to be distinguished from the agreeable and the good. The agreeable excites my interest because it arouses my desire; the good interests me because it is to be made real by me. In confronting the beautiful I have no such interest that is connected with my person. What is it then, by means of which my selfless delight is attracted? I can be pleased by a thing only when its purpose is fulfilled, when it is so organized that it serves an end. Fitness to purpose pleases; incongruity displeases, but as I have no interest in the reality of the beautiful thing, as the mere sight of it satisfies me, it is also

not necessary that the beautiful object really serves a purpose.

The purpose is of no importance to me; what I demand is only the appropriateness. For this reason, Kant calls an object ”beautiful” in which we perceive fitness to purpose without thinking at the same time of a definite purpose.

What Kant gives in this exposition is not merely an explanation but also a justification of art. This is best seen if one remembers Kant's feeling in regard to his world conception. He expresses his feeling in profound, beautiful words: Two things fill the heart with ever new and always increasing admiration and awe: The starred heaven above me and the moral law within me. At first, the sight of an innumerable world quant.i.ty annihilates, as it were, my importance as a living creature, which must give back to the planet that is a mere dot in the universe the matter out of which it became what it is, after having been for a short while (one does not know how) provided with the energy of life. On second consideration, however, this spectacle infinitely raises my value as an intelligent being, through my (conscious and free) personality in which the moral law reveals to me a life that is independent of the whole world of the senses, at least insofar as this can be concluded from the purpose-directed destination of my existence, which is not hemmed in by the conditions and limitations of this life but extends into the infinite.

The artist now transplants this purpose-directed destination, which, in reality, rules in the realm of the moral world, into the world of the senses. Thus, the world of art stands between the realm of the world of observation that is dominated by the eternal stern laws of necessity, which the human mind itself has previously laid into this world, and the realm of free morality in which commands of duty, as the result of a wise,

divine world-order, set out direction and aim. Between both realms the artist enters with his works. Out of the realm of the real he takes his material, but he reshapes this material at the same time in such a fas.h.i.+on that it becomes the bearer of a purpose-directed harmony as it is found in the realm of freedom. That is to say, the human spirit feels dissatisfied both with the realms of external reality, which Kant has in mind when he speaks of the starred heaven and the innumerable things of the world, and also with the realm of moral law. Man, therefore, creates a beautiful realm of ”semblance,” which combines the rigid necessity of nature with the element of a free purpose. The beautiful now is not only found in human works of art, but also in nature. There is nature-beauty as well as art-beauty. This beauty of nature is there without man's activity. It seems, therefore, as if there were observable in the world of reality, not merely the rigid law-ordered necessity, but a free wisdom-revealing activity as well. The phenomenon of the beautiful, nevertheless, does not force us to accept a conception of this kind, for what it offers is the form of a purpose-directed activity without implying also the thought of a real purpose. Furthermore, there is not only the phenomenon of integrated beauty but also that of integrated ugliness. It is, therefore, possible to a.s.sume that in the mult.i.tude of natural events, which are interconnected according to necessary laws, some happen to occur - accidentally, as it were - in which the human mind observes an a.n.a.logy with man's own works of art. As it is not necessary to a.s.sume a real purpose, this element of free purpose, which appears as it were by accident, is quite sufficient for the esthetic contemplation of nature.

The situation is different when we meet the ent.i.ties in nature to which the purpose concept is not merely to be attributed as accidental but that carry this purpose really within themselves. There are also ent.i.ties of this kind according to

Kant's opinion. They are the organic beings. The necessary law-determined connections are insufficient to explain them; these, in Spinoza's world conception are considered not only necessary but sufficient, and by Kant are considered as those of the human mind itself. For an ”organism is a product of nature in which everything is, at the same time, purpose, just as it is cause and also effect.” An organism, therefore, cannot be explained merely through rigid laws that operate with necessity, as is the case with inorganic nature. It is for this reason that, although Kant himself had, in his General Natural History and Theory of the Heavens, undertaken the attempt to ”discuss the const.i.tution and the mechanical origin of the entire world structure according to Newtonian principles,” he is of the opinion that a similar attempt, applied to the world of organic beings, would necessarily fail. In his Critique of Judgment, he advances the following statement: It is, namely, absolutely certain that in following merely mechanical principles of nature we cannot even become sufficiently acquainted with organisms and their inner possibility, much less explain them. This is so certain that one can boldly say that it would be absurd for man to set out on any such attempt or to hope that at some future time a Newton could arise who would explain as much as the production of a blade of gra.s.s according to natural laws into which no purpose had brought order and direction. Such a knowledge must, on the contrary, be altogether denied to man.

Kant's view that it is the human mind itself that first projects the laws into nature that it then finds in it, is also irreconcilable with another opinion concerning a purpose- directed ent.i.ty, for a purpose points to its originator through whom it was laid into such an ent.i.ty, that is, to the rational originator of the world. If the human mind could explain a teleological being in the same way as an ent.i.ty that is merely

const.i.tuted according to natural necessity, it would also have to be capable of projecting laws of purpose out of itself into the things. Not merely would the human mind have to provide laws for the things that would be valid with regard to them insofar as they are appearances of his inner world, but it would have to be capable of prescribing their own destination to the things that are completely independent of the mind.

The human mind would, therefore, have to be not merely a cognitive, but a creative, spirit; its reason would, like that of G.o.d, have to create the things.

Whoever calls to mind the structure of the Kantian world conception as it has been outlined here will understand its strong effect on Kant's contemporaries and also on the time after him, for he leaves intact all of the conceptions that had formed and impressed themselves on the human mind in the course of the development of western culture. This world conception leaves G.o.d, freedom and immortality, to the religious spirit. It satisfies the need for knowledge in delineating a territory for it inside the limits of which it recognizes unconditionally certain truths. It even allows for the opinion that the human reason is justified to employ, not merely the eternal rigorous natural laws for the explanation of living beings, but the purpose concept that suggests a designed order in the world.

But at what price did Kant obtain all this! He transferred all of nature into the human mind and transformed its laws into laws of this mind. He ejected the higher world order entirely from nature and placed this order on a purely moral foundation. He drew a sharp line of demarcation between the realm of the inorganic and that of the organic, explaining the former according to mechanical laws of natural necessity and the latter according to teleological ideas. Finally, he tore the realm of beauty and art completely out of its connection with the rest of reality, for the teleological form that is to be

observed in the beautiful has nothing to do with real purposes. How a beautiful object comes into the world is of no importance; it is sufficient that it stimulates in us the conception of the purposeful and thereby produces our delight.

Kant not only presents the view that man's knowledge is possible so far as the law-structure of this knowledge has its origin in the self-conscious soul, and the certainty concerning this soul comes out of a source that is different from the one out of which our knowledge of nature springs. He also points out that our human knowledge has to resign before nature, where it meets the living organism in which thought itself seems to reign in nature. In taking this position, Kant confesses by implication that he cannot imagine thoughts that are conceived as active in the ent.i.ties of nature themselves.

The recognition of such thoughts presupposes that the human soul not merely thinks, but in thinking shares the life of nature in its inner experience. If somebody discovered that thoughts are capable not merely of being received as perceptions, as is the case with the Platonic and Aristotelian ideas, but that it is possible to experience thoughts by penetrating into the ent.i.ties of nature, then this would mean that again a new element had been found that could enter the picture of nature as well as the conception of the self- conscious ego. The self-conscious ego by itself does not find a place in the nature picture of modern times. If the self- conscious ego, in filling itself with thought, is not merely aware that it forms this thought, but recognizes in thought a life of which it can know, ”This life can realize itself also outside myself,” then this self-conscious ego can arrive at the insight, ”I hold within myself something that can also be found without.” The evolution of modern world conception thus urges man on to the step: To find the thought in the self- conscious ego that is felt to be alive. This step Kant did not

take; Goethe did.

In all essential points, Goethe arrived at the opposite to Kant's conception of the world. Approximately at the same time that Kant published his Critique of Pure Reason, Goethe laid down his creed in his prose hymn, Nature, in which he placed man completely into nature and in which he presented nature as bearing absolute sway, independent of man: Her own and man's lawgiver as well. Kant drew all nature into the human mind. Goethe considered everything as belonging to this nature; he fitted the human spirit into the natural world order: Nature! We are surrounded and enveloped by her, incapable of leaving her domain, incapable of penetrating deeper into her. She draws us into the rounds of her dance, neither asking nor warning, and whirls away with us until we fall exhausted from her arms. . . . A11 men are in her and she is in them. . . .

Even the most unnatural is Nature; even the clumsiest pedantry has something of her genius. . . .We obey her laws even when we resist them; we are working with her even when we mean to work against her. . . . Nature is everything. . . . She rewards and punishes, delights and tortures herself. . . . She has placed me into life, she will also lead me out of it. I trust myself into her care. She may hold sway over me. She will not hate her work. It was not I who spoke of her. Nay, it was Nature who spoke it all, true and false. Nature is the blame for all things; hers is the merit.

This is the polar opposite to Kant's world conception.
