CHAPTER V – The Adventure of Reason
*
Goethe’s observation of the single plant in statu agendi had trained him to recognize things of quite different outer appearance as identical in their inner nature. Leaf, sepal, petal, etc., much as they differ outwardly, yet showed themselves to him as manifestations of one and the same spiritual archetype. His idea of Metamorphosis enabled him to reduce what in outer appearance seems incompatibly different to its common formative principle. His next step was to observe the different appearances of one and the same species in different regions of the earth, and thus to watch the capacity of the species to respond in a completely flexible way to the various climatic conditions, yet without concealing its inner identity in the varying outer forms. His travels in Switzerland and Italy gave him opportunity for such observations, and in the Alpine regions especially he was delighted at the variations in the species which he already knew so well from his home in Weimar. He saw their proportions, the distances between the single parts, the degree of lignification, the intensity of colour, etc., varying with the varied conditions, yet never concealing the identity of the species.
Having once advanced in his investigations from metamorphosis in the parts of the single plant to metamorphosis among different representatives of single plant species, Goethe had to take only one further, entirely decisive, step in order to recognize how every member of the plant kingdom is the manifestation of a single formative principle common to them all. He was thus faced with the momentous task of preparing his spirit to think an idea from which the plant world in its entire variety could be derived.
Goethe did not take such a step easily, for it was one of his scientific principles never to think out an idea prematurely. He was well aware that he who aspires to recognize and to express in idea the spirit which reveals itself through the phenomena of the sense-world must develop the art of waiting – of waiting, however, in a way intensely active, whereby one looks again and yet again, until what one looks at begins to speak and the day at last dawns when, through tireless ‘re-creation of an ever-creating nature’, one has grown ripe to express her secrets openly. Goethe was a master in this art of active waiting.
* It was in the very year that Galvani, through his chance discovery, opened the way to the overwhelming invasion of mankind by the purely physical forces of nature, that Goethe came clearly to see that he had achieved the goal of his labours. We can form some picture of the decisive act in the drama of his seeking and finding from letters written during the years 1785-7.
In the spring of 1785 he writes to a friend in a way that shows him fully aware of his new method of studying nature, which he recognized was a reading of her phenomena: ‘I can’t tell you how the Book of Nature is becoming readable to me. My long practice in spelling has helped me; it now suddenly works, and my quiet joy is inexpressible.’ Again in the summer of the following year: ‘It is a growing aware of the Form with which again and again nature plays, and, in playing, brings forth manifold life.’
Then Goethe went on his famous journey to Italy which was to bear such significant fruit for his inner life, both in art and in science. At Michaelmas, 1786, he reports from his visit to the botanical garden in Padua that ‘the thought becomes more and more living that it may be possible out of one form to develop all plant forms’. At this moment Goethe felt so near to the basic conception of the plant for which he was seeking, that he already christened it with a special name. The term he coined for it is Urpflanze, literally rendered archetypal plant, or ur-plant, as we propose quite simply to call it.6
It was the rich tropical and sub-tropical vegetation in the botanical gardens in Palermo that helped Goethe to his decisive observations. The peculiar nature of the warmer regions of the earth enables the spirit to reveal itself more intensively than is possible in the temperate zone. Thus in tropical vegetation many things come before the eye which otherwise remain undisclosed, and then can be detected only through an effort of active thought. From this point of view, tropical vegetation is ‘abnormal’ in the same sense as was the proliferated rose which confirmed for Goethe’s physical perception that inner law of plant-growth which had already become clear to his mind.
During his sojourn in Palermo in the spring of 1787 Goethe writes in his notebook: ‘There must be one (ur-plant): how otherwise could we recognize this or that formation to be a plant unless they were all formed after one pattern?’ Soon after this, he writes in a letter to the poet Herder, one of his friends in Weimar:
‘Further, I must confide to you that I am quite close to the secret of plant creation, and that it is the simplest thing imaginable. The ur-plant will be the strangest creature in the world, for which nature herself should envy me. With this model and the key to it one will be able to invent plants ad infinitum; they would be consistent; that is to say, though non-existing, they would be capable of existing, being no shades or semblances of the painter or poet, but possessing truth and necessity. The same law will be capable of extension to all living things.’
*
To become more familiar with the conception of the ur-plant, let us bring the life-cycle of the plant before our inner eye once again. There, all the different organs of the plant-leaf, blossom, fruit, etc. – appear as the metamorphic revelations of the one, identical active principle, a principle which gradually manifests itself to us by way of successive heightening from the cotyledons to the perfected glory of the flower. Amongst all the forms which thus appear in turn, that of the leaf has a special place; for the leaf is that organ of the plant in which the ground-plan of all plant existence comes most immediately to expression. Not only do all the different leaf forms arise, through endless changing, out of each other, but the leaf, in accordance with the same principle, also changes itself into all the other organs which the plant produces in the course of its growth.
