# 3 Goethe's view of nature

*According to the latest publications of the Goethe Archive*

Once before, a celebration of Goethe's birthday prompted a man here in Frankfurt to openly confess that he also saw in Germany's greatest poet a spirit who was one of the first to be considered when speaking of the pathfinders in the field of natural knowledge. Arthur Schopenhauer wrote an article in the Goethe album that greeted August 28, 1849, which was as full of strong words of anger at the opponents of Goethe's Theory of Colors as the philosopher's soul was full of enthusiastic appreciation for Goethe the naturalist. "Not crowned monuments, nor canon salutes, nor the ringing of bells, let alone banquets with speeches, are sufficient to atone for the grave and outrageous injustice Goethe suffers in regard to his color theory." Far be it from me to draw your attention today to this particular point of the poet's scientific activity. The time will come when the scientific prerequisites for an understanding between researchers will also exist for this question. At present, physical research is moving in a direction that cannot lead to Goethean thinking. Goethe also wants to bring the consideration of purely physical phenomena as close as possible to the human-personal. To him, man is "the greatest and most exact physical apparatus that can exist", and this is - in his opinion - "precisely the greatest misfortune of modern physics, that one has, as it were, separated experiments from man and merely wants to recognize nature in what artificial instruments show, indeed, to limit and prove what it can achieve". In their anxious avoidance of everything subjective and personal, however, the physicists of our time go much further than those whom Goethe intended to target with these words. The ideal of our contemporaries in this respect is to trace all phenomena back to as few inanimate basic forces as possible, which act according to purely mathematical and mechanical laws. Goethe's mind was directed elsewhere. In his view, what is only hidden in the rest of nature appears in man in his very own form. For Goethe, the human spirit is the highest form of the natural process, the organ that nature has created in order to reveal its secret. All the forces that tremble through the world penetrate the human soul in order to express what they are in essence. Goethe could not conceive of a nature separate from man. A dead, spiritless matter was impossible in his imagination. He rejected an explanation of nature with principles from which man could not also be understood in terms of his existence and essence.

Just as understandable as the opposition of the physicists is the approval that Goethe's view of nature found among some of the most outstanding investigators of the phenomena of life, especially the most intellectual natural scientist of our time, Ernst Haeckel. Haeckel, who has given Darwin's ideas on the origin of organisms a perfection appropriate to German thoroughness, even attaches the greatest importance to recognizing the harmony of his basic convictions with those of Goethe. For Haeckel, Darwin's question about the origin of organic forms immediately became the highest task that the science of organic life can set itself, that of the origin of man. And he was compelled to assume such natural principles in place of the dead matter of the physicists that one need not stop at human beings. In his recently (1892) published work "Monism as a Bond between Religion and Science", which I am convinced is the most significant manifestation of the latest natural philosophy, Haeckel expressly emphasized that he could no more conceive of an "immaterial living spirit" than of a "dead spiritless matter". And Goethe's words that "matter can never exist and be effective without spirit, spirit never without matter" are entirely consistent with this.

In contrast to the stubborn resistance of physicists, we find here a conception of nature that proudly claims Goethe's ideas for itself.

For those who set themselves the task of fully appreciating Goethe's genius in a particular field, the question now arises: Does the direction of modern natural science that we have just characterized do full justice to Goethe? Those who are only concerned with this natural science will of course simply ask: to what extent does Goethe agree with me? He regards Goethe as a forerunner of his own direction with regard to those views which the latter has in common with him. His yardstick is the contemporary view of nature. Goethe is judged by it. My point of view in the following arguments is towards these judges: How would Goethe have behaved towards those naturalists who today speak approvingly of him in their way? Would he have believed that they had brought to light ideas that he had only anticipated, or would he rather have thought that the form they had given to natural science corresponded only imperfectly to his beginnings? How we answer this question and how we ourselves then relate to Goethe's world view will determine whether we see Goethe, the natural scientist, as merely a more or less interesting phenomenon in the history of science or whether we also want to make his creations fruitful for our knowledge in the field of natural science and, to use Herman Grimm's phrase, place him in the service of the times.

The point is to penetrate the spirit of Goethe's view of nature from his own way of looking at and thinking, not from an external comparison with scientific ideas of the present. If we want to understand Goethe correctly, the individual achievements in which his rich mind laid down his scientific thoughts are less important than the intentions and aims from which they emerged. Outstanding men can become epoch-making for mankind in two ways. Either they find the solution to questions that have already been asked, or they find new problems in phenomena that their predecessors carelessly passed by. Galileo, for example, influenced the development of science in the latter way. Countless people before him had seen a swinging body without noticing anything remarkable about it; this phenomenon revealed to his gaze the great task of learning the laws of pendulum motion, and he created entirely new scientific foundations in this field of mechanics. In spirits of this kind, needs that their predecessors had not yet known arise for the first time. And the need opens the eyes to a discovery.

A need of this kind awoke in Goethe at an early stage. His research instinct was initially ignited by the diversity of organic life. He saw the abundance of forms in the animal and plant kingdoms with a different eye than his scientific contemporaries. They believed that they had done enough by observing the differences between the individual forms, identifying the peculiarities of each particular species and genus and, on the basis of this work, creating an external order, a system of living things. Linné, the botanist, in particular, was a master in this art of classification. Goethe became acquainted with this man's writings in 1782, as we know from his correspondence with Frau von Stein. What was the most important thing for Linné, to precisely determine the characteristics that distinguish one form from another, was initially not even a consideration for Goethe. For him, the question arose: what lives in the infinite abundance of the plant world that unites this diversity into a unified natural kingdom? He first wanted to understand what a plant actually is, and then he hoped to understand why plant nature manifests itself in such an infinite number of forms. He himself later said of his relationship with Linné: "That which he tried to keep apart by force had to strive towards unification according to the innermost needs of my being." That Goethe was on the right path to finding a law of nature here can be seen from a simple observation of how natural laws express themselves in phenomena. Every natural phenomenon emerges from a series of circumstances that determine it. Let's take something very simple. If I throw a stone in a horizontal direction, it will fall to earth at a certain distance from me. It has described a very specific line in space during its flight. This line is dependent on three conditions: the force with which I push the stone, the attraction that the earth exerts on it, and the resistance that the air offers it. I can explain the movement of the stone to myself if I know the laws according to which the three conditions act on it. That phenomena of inanimate nature must be explained in this way, that is, by seeking their causes and their laws of action, was not doubted by anyone concerned with the history of science at the time of Goethe's appearance. into consideration. But the situation was different when it came to the phenomena of life. Genera and species were seen before us and within them each being was equipped with such an arrangement, with such organs, as corresponded to its vital needs. Such a regularity was only considered possible if the organic forms were designed according to a well-considered plan of creation, according to which each organ received the formation it must have if it is to fulfill its intended purpose. Thus, while one sought to explain the phenomena of inanimate nature from causes that lie within the world, one believed that one had to assume extra-worldly explanatory principles for organisms. The attempt to attribute the phenomena of life to causes that lie within the world we can observe was not attempted before Goethe; indeed, as late as 1790, the famous philosopher Immanuel Kant called any such attempt "an adventure of reason". One simply imagined each of Linnaeus' species to have been created according to a certain preconceived plan and thought one had explained a phenomenon when one recognized the purpose it was supposed to serve. Such a way of looking at things could not satisfy Goethe. The idea of a God who leads a separate existence outside the world and directs his creation according to externally imposed laws was alien to him. Throughout his life, he was dominated by the thought:

> "What would a God be who only pushed from the outside,  
> Run the universe in circles on his finger?  
> It befits him to move the world within,  
> Nature in itself, to nurture itself in nature,  
> So that what lives and weaves and is in him,  
> Never misses its power, never misses its spirit."

What did Goethe have to look for in the science of organic nature in accordance with this attitude? Firstly, a law that explains what makes a plant a plant and an animal an animal; secondly, another that makes it comprehensible why the common underlying principle of all plants and animals appears in such a diversity of forms. The basic essence that expresses itself in every plant, the animality that is found in all animals, that is what he sought first. The artificial partitions between the individual genera and species had to be torn down, it had to be shown that all plants are only modifications of an original plant, all animals of an original animal. Kant had declared it impossible that we could recognize the original form that underlies all organisms and that we are able to find the lawful causes within our world of appearance that cause this original form to appear once as a lily and another time as an oak. Goethe undertook "the adventure of reason" and thus accomplished a scientific deed of the first order. Goethe thus set out to form an idea of that original form and to seek the laws and conditions that explain its appearance in its manifold forms. In his opinion, however, science must do justice to both of these requirements. He who has no concept of the original form can indeed state the facts under whose influence one organic form has transformed itself into another, but he can never arrive at a real explanation. That is why Goethe considered it his first task to find the original plant and the original animal or, as he also called it, the type of plants and animals.

What does Goethe understand by this type? He spoke clearly and unambiguously about it. He says that he felt the need to "establish a type against which all mammals could be tested for similarity and difference, and just as I had previously sought out the original plant, I now sought to find the original animal, which ultimately means: the concept, the idea of the animal". And another time with even greater clarity: "But once you have grasped the idea of this type, you will realize how impossible it is to establish a single genus as a canon. The individual cannot be a pattern of the whole, and so we must not seek the pattern for all in the individual. The classes, genera, species and individuals behave like the cases to the law: they are contained in it, but they do not contain or give it." So if Goethe had been asked whether he saw his archetype, his type, realized in a particular animal or plant form that existed at some time, he would undoubtedly have answered with a resounding no. He would have said: Just like the domestic dog, even the simplest animal organism is only a special case of what I understand by type. The type is not realized at all in the external world, but it arises as an idea within us when we consider what living beings have in common. As little as the physicist makes a single case, a random phenomenon, the starting point of his investigations, as little may the zoologist or botanist address a single organism as a primordial organism.

And here is the point at which it must become clear that the newer Darwinism falls far short of Goethe's basic ideas. This scientific current finds that there are two causes under the influence of which one organic form can transform itself into another: adaptation and the struggle for existence. Adaptation is understood to mean the fact that an organism undergoes a change in its vital activity and in its form as a result of influences from the outside world. As a result, it acquires characteristics that its ancestors did not have. In this way, therefore, a transformation of existing organic forms can take place. The law of the struggle for existence is based on the following considerations. Organic life produces many more germs than there is room on earth for their nourishment and development. Not all of them can reach full maturity. Each developing organism seeks the means for its existence from its environment. It is inevitable that with the abundance of germs a struggle will arise between the individual beings. And since only a limited number can find a livelihood, it is natural that this consists of those who prove to be the stronger in the struggle. These will emerge victorious. But which are the strongest? Undoubtedly those with an organization that proves to be adequate to provide the means of life. The creatures with inappropriate organization must succumb and die out. Therefore, says Darwinism, there can only be functional organizations. The others have simply perished in the struggle for existence. Taking these two principles as a basis, Darwinism explains the origin of species in such a way that organisms transform themselves through adaptation under the influence of the outside world, transplant the new characteristics gained in this way to their descendants and, of the forms transformed in this way, always preserve those that have assumed the most appropriate form in the transformation process.

Goethe would undoubtedly have no objection to these two principles. We can prove that he was already familiar with both. But he did not consider them sufficient to explain the forms of organic life. For him they were external conditions under the influence of which what he called type takes on particular forms and can transform itself in the most varied ways. Before something transforms, however, it must first exist. Adaptation and the struggle for existence presuppose the organic, which they influence. Goethe first sought to obtain the necessary precondition. His essay "An attempt to explain the metamorphosis of plants", published in 1790, pursues the idea of finding an ideal plant form that underlies all plant beings as their archetype. He later attempted to do the same for the animal world.

Just as Copernicus sought the laws for the movements of the limbs of our solar system, Goethe sought those according to which a living organism is formed. I will not go into the details, but will gladly admit that they are in great need of improvement. However, Goethe's undertaking represents a decisive step in exactly the same way as Copernicus' explanation of the solar system, which was also significantly improved by Kepler.

I have already in 1883 (in my edition of Goethe's scientific writings in Kürschners Nat. Lit, 1.vol.), I endeavored to show that the newer natural science has only brought one side of Goethe's view to fruition.[^1] The study of the external conditions for the transformation of species is in full swing. Haeckel ingeniously sought to determine the degrees of relationship of the forms of the animal world. Virtually nothing has been done to discover the inner laws of organism formation. Indeed, there are researchers who regard such laws as mere figments of the imagination. They believe they have done all that is necessary when they show how the more complicated living beings have gradually built themselves up from elementary organisms. And these elementary organic entities are to be explained by the mere lawful combination of inorganic substances in the same way as the formation of a chemical compound is explained. Thus one would have happily accomplished the feat of explaining life by destroying it or, rather, by thinking of it as non-existent. Goethe would never have agreed with such an approach. He sought natural laws for the living, but nothing was further from his mind than the attempt to simply transfer the laws of the inanimate to the animate.

Until the opening of the Goethe Archive, some of my assertions could perhaps have been disputed, although I believe that for anyone who reads Goethe's scientific writings in context, there is no doubt about the way their author thought. But these writings do not form a coherent whole. They do not represent an all-round view of nature, but only fragments of such a view. They have gaps which anyone who wants to gain an idea of Goethe's world of ideas must fill in hypothetically. Goethe's handwritten estate, which is in the Goethe Archive in Weimar, now makes it possible to fill in numerous and important gaps. It has given me the gratifying certainty that the ideas I had previously formed about Goethe's scientific thinking, which I have just characterized, are completely correct. I had no need to modify my concepts, but today I can substantiate with Goethe's own words many things that I was only able to represent hypothetically before the opening of the archive.[^2]

We read, for example, in an essay published in the Weimar edition of the sixth volume of Goethe's scientific writings: The metamorphosis of plants "shows us the laws according to which plants are formed. It draws our attention to a double law: 1. to the law of inner nature, by which plants are constituted, 2. to the law of external circumstances, by which plants are modified."

It is particularly interesting, however, that we can follow the train of thought step by step through which Goethe sought to recognize this law of inner nature, according to which plants are formed. These thoughts developed in Goethe during his Italian journey. The notepads on which he jotted down his observations have been preserved. The Weimar edition has included them in the seventh volume of his scientific writings. They are a model of how a researcher seeks to fathom the secrets of nature with a philosophical eye. With the same deep seriousness with which he pursued his artistic interests in Italy, he endeavoured to recognize the laws of plant life. These sheets provide full proof that a long endeavor lay behind Goethe when, around the middle of 1787, he elevated the hypothesis of the primordial plant to a decisive scientific conviction.

The poet devoted even more time and effort to applying his ideas to the animal kingdom and human beings. As early as 1781, he began the serious study of anatomy in Jena. In this field, Goethe found a scientific view that his whole nature resisted. It was believed that there was a slight difference between humans and animals in terms of anatomical structure. Animals have a small bone (intermaxillary bone) between the two symmetrical halves of the upper jaw, which contains the upper incisors. In humans, it was believed, there was no such bone. This view must have immediately appeared to Goethe to be a mistake. Where there is such a similarity of structure as in the skeleton of man and that of the higher animals, there must be a deeper natural law underlying it, where such a difference in detail is not possible. In 1784 Goethe succeeded in proving that the intermediate bone is also present in man, and thus the last obstacle that stood in the way of establishing a uniform type for all animal organizations up to man was removed. As early as 1790, Goethe set about following up his essay on the metamorphosis of plants with a similar essay "On the Form of Animals", which unfortunately remained a fragment. It can be found in the eighth volume of the natural scientific writings of the \Weimar edition. Goethe then set about realizing this intention again in 1795, but this time he did not finish it either. We can recognize his intentions in detail from the two fragments; the execution of the enormous idea would have taken more time than the poet had available given his wide-ranging interests. However, these endeavors are followed by a single discovery that clearly shows us what they were aimed at. Just as Goethe sought to trace all plants back to the original plant and all animals back to the original animal, he also strove to explain the individual parts of one and the same organism from a basic component that has the ability to transform itself in a variety of ways. He thought that all organs can be traced back to a basic form that only takes on different shapes. He saw an animal and a plant individual as consisting of many details. These details are identical in structure, but identical or similar, dissimilar and dissimilar in appearance. The more imperfect the creature is, the more the parts resemble each other and the more they resemble the whole. The more perfect the creature becomes, the more dissimilar the parts become. Goethe therefore strove to find similarities between the individual parts of an organism. In the case of the animal skeleton, this led him to an idea of far-reaching significance, that of the so-called vertebral nature of the skull bones. We are dealing here with the view that the bones that surround the brain have the same basic shape as those that make up the spine. Goethe probably suspected this soon after beginning his anatomical investigations. It became a complete certainty for him in 1790, when he found a sheep's skull on the dunes of the Lido in Venice, which had fallen apart so happily that Goethe believed he could clearly recognize the individual vertebral bodies in the pieces. Here, too, it has been claimed that Goethe's discovery was much more of a lucky idea than a real scientific result. It seems to me, however, that it is precisely the latest work in this field that provides full proof that the path Goethe took was the right one. In 1872, the outstanding anatomist Carl Gegenbaur published studies on the head skeleton of the Selachians or prehistoric fishes, which show that the skull is the remodeled end part of the backbone and the brain is the remodeled end part of the spinal cord. One must now imagine that the bony skull capsule of the higher animals consists of remodeled vertebral bodies which, however, in the course of the development of higher animal forms from lower ones, have gradually assumed such a shape and have grown together in such a way that they appear suitable for enclosing the brain. Therefore, the vertebral theory of the skull can only be studied in connection with the comparative anatomy of the brain. That Goethe was already considering this matter from this point of view in 1790 is shown by an entry in his diary, which was recently found in Goethe's archive: "The brain itself is only one large main ganglion. The organization of the brain is repeated in each ganglion, so that each ganglion is to be regarded as a small subordinate brain."

From all this it is clear that Goethe's scientific method is equal to any criticism and that in the pursuit of his natural philosophical ideas he made a series of individual discoveries which today's science, albeit in an improved form, must also consider to be important components of knowledge of nature. However, Goethe's significance does not lie in these individual discoveries, but in the fact that his way of looking at things led him to completely new guiding points of view on the knowledge of nature. He was fully aware of this himself. On August 18, 1787, he wrote to Knebel from Italy: "After what I have seen of plants and fish near Naples and in Sicily, if I were ten years younger, I would be very tempted to make a journey to India, not to discover new things, but to look at what I have discovered in my own way." These words express Goethe's view of scientific knowledge. Faithful, sober observation alone cannot lead to the goal. Only when we find the appropriate point of view from which to look at things do they become comprehensible to us. Through his way of looking at things, Goethe destroyed the great dividing wall between inanimate and animate nature; indeed, it was he who first elevated the doctrine of organisms to the rank of a science. Schiller expressed the essence of this approach in meaningful words in a letter to Goethe on August 23, 1793: "I have long watched the course of your mind, albeit from quite a distance, and have noted the path you have marked out with ever renewed admiration. You are looking for the extraordinary in nature, but you are looking for it in the most difficult way, which any weaker force would be wary of. You take the whole of nature together in order to shed light on the individual; in the totality of its manifestations you seek the ground of explanation for the individual. From the simple organization you ascend step by step to the more intricate, in order finally to build the most intricate of all, man, genetically from the materials of the whole edifice of nature. By recreating him from nature, as it were, you seek to penetrate his hidden technology."

From this school of thought, a view of nature had to develop that was equally far removed from crude materialism and nebulous mysticism. For them it was self-evident that the particular could only be recognized through experience, the general, the great lawful connections of nature only by ascending from observation to the idea. Only where both interact: Idea and experience, Goethe sees the spirit of true natural research. He expresses this aptly with the words: "Time is governed by the pendulum swing, the moral and scientific world by the alternating movement from idea to experience" (Goethes Werke, II. Abteilung, 6. Band, p. 354). Goethe believed that only in the idea could he come close to the secret of life. He found causes at work in the organic world that are only partly perceptible to the senses. He sought to recognize the other part by attempting to recreate the laws of nature in images. Although life expresses itself in sensory reality, it does not exist in it. That is why it cannot be found through sensory experience. The higher spiritual powers must intervene. It is popular today to recognize only the intellect as having a right to speak in science alongside sober observation. Goethe believed that he could only come into possession of the truth by exerting all his intellectual powers. That is why he never tired of putting himself in relation to the most diverse types of scientific endeavor. In the scientific institutes of the Jena University he sought to acquire the factual knowledge for his ideas; from its famous philosophical teachers and from Schiller he sought information about the philosophical justification of his school of thought. Goethe was not a philosopher in the true sense of the word, but his way of looking at things was philosophical. He did not develop any philosophical concepts, but his scientific ideas are based on a philosophical spirit. By his nature, Goethe could neither be a one-sided philosopher nor a one-sided observer. Both sides worked harmoniously together in him in the higher unity, the philosophical observer, just as art and science are united again in the comprehensive personality of Goethe, who interests us not only in this or that branch of his work, but in its entirety as a world-historical phenomenon. In Goethe's mind, science and art worked together. We see this best when, in view of the Greek works of art in Italy, he wrote that he believed that the Greeks followed the same laws in their creations as nature itself, and he remarked that he believed he was on the trail of these laws. He wrote this at a time when he was pursuing the idea of the primordial plant. There can therefore be no doubt that Goethe thought of the artist's work as being guided by the same basic maxims that nature follows in its productions. And because he suspected the same basic essences in nature that guided him as an artist in his own work, he was driven by a scientific knowledge of them. Goethe professed a strictly unified or monistic view of the world. He saw unified fundamental powers ruling from the simplest process of lifeless nature right up to the imagination of man, from which the works of art spring.

Rudolf Virchow emphasizes in the remarkable speech he gave on August 3 of this year to celebrate the birthday of the founder of Berlin University that the philosophical era of German science, in which Fichte, Schelling and Hegel set the tone, has been definitively over since Hegel's death and that we have been living in the age of the natural sciences ever since. Virchow praises this age for the fact that it increasingly understood that natural science could only be understood by studying nature itself: in museums, collections, laboratories and institutes, and that no information about natural processes could be gained from the study rooms of philosophers. This is the expression of a widespread prejudice of our time. The advocate of a strictly scientific view of the world would have to say to himself that what belongs to external nature and what we alone can accommodate in scientific institutes is only one part of nature, and that the other, certainly no less essential part, is not to be sought in the study, but certainly in the mind of the philosopher. This is how Goethe thought, and his thinking is therefore more scientific than that of modern natural science. The latter leaves the human urge for knowledge completely unsatisfied when it is a matter of something higher than what is accessible to sensible observation. It is therefore no wonder that Virchow has to complain at the same time about the worst intrusions of mysticism into the field of the science of life. What science fails to do, a deeper need seeks in all kinds of mysterious forces of nature, namely the explanation of facts once they exist. And Virchow also admits that the age of natural science has so far been unable to explain the essence of life and the human spirit.

But who can hope to see thought with his eyes, to perceive life with a microscope? The only way to achieve something here is to go in the second direction, through which Goethe sought to reach the primordial organisms. The questions that modern natural science cannot answer are precisely those that Goethe undertakes to solve in a way that people today do not want to know about. This opens up a field in which Goethe's scientific work can be put at the service of the times. They will prove effective precisely where the current method proves impotent. It is not only a matter of doing justice to Goethe and assigning his research the right place in history, but also of continuing to cultivate his way of thinking with our more perfect means.

He himself was primarily concerned that the world should recognize what his view of nature meant in general, and only secondarily what he was able to achieve with the help of this view with the means of his time in particular.

The scientific age has torn the bond between experience and philosophy. Philosophy has become the stepchild of this age. However, the need for a philosophical deepening of our knowledge has already arisen in many cases. For the time being, this need is still trying to satisfy itself in a number of misguided ways. The overestimation of hypnotism, spiritualism and mysticism are among them. Raw materialism is also an attempt to find the way to a philosophical overall view of things. Injecting a little philosophy into the scientific age is a desirable goal for many today. May we remember at the right time that there is a path from natural science to philosophy and that this is mapped out in Goethe's writings.
