In the fully developed plant this rhythm repeats itself three times in succession and at ever higher levels, so that the plant, in climbing from stage to stage, each time goes through a process of withdrawal before appearing at the next. The greater the creative power required at a certain stage, the more nearly complete must be the withdrawal from outer appearance. This is why the most extreme withdrawal of the plant into the state of being takes place in the seed, when the plant prepares itself for its transition from one generation to another. Even earlier, the flower stands towards the leaves as something like a new generation springing from the small organ of the calyx, as does the fruit to the flower when it arises from the tiny organs of reproduction. In the end, however, nothing appears outwardly so unlike the actual plant as the little seed which, at the expense of all appearance, has the power to renew the whole cycle.
Through studying the plant in this way Goethe grew aware also of the significance of the nodes and eyes which the plant develops as points where its vital energy is specially concentrated; not only the seed, but the eye also, is capable of producing a new, complete plant. In each of these eyes, formed in the axils of the leaves, the power of the plant is present in its entirety, very much as in each single seed.
In other ways, too, the plant shows its capacity to act as a whole at various places of its organism. Otherwise, no plant could be propagated by cuttings; in any little twig cut from a parent plant, all the manifold forces operative in the gathering, transmuting, forming of matter, that are necessary for the production of root, leaf, flower, fruit, etc., are potentially present, ready to leap into action provided we give it suitable outer conditions. Other plants, such as gloxinia and begonia, are known to have the power of bringing forth a new, complete plant from each of their leaves. From a small cut applied to a vein in a leaf, which is then embedded in earth, a root will soon be seen springing downward, and a stalk with leaves rising upward.
A particular observation made by Goethe in this respect is of interest for methodological reasons. In the introduction to his treatise Metamorphosis of Plants, when referring to the regressive metamorphosis of stamens into petals as an example of an irregular metamorphosis, he remarks that 'experiences of this kind of metamorphosis will enable us to disclose what is hidden from us in the regular way of development, and to see clearly and visibly what we should otherwise only be able to infer'. In this remark Goethe expresses a truth that is valid in many spheres of life, both human and natural. It is frequently a pathological aberration in an organic entity that allows us to see in physical appearance things that do not come outwardly to the fore in the more balanced condition of normal development, although they are equally part of the regular organic process.
An enlightening experience of this kind came to Goethe's aid when one day he happened to see a 'proliferated' rose (durchgewachsene Rose), that is, a rose from whose centre a whole new plant had sprung. Instead of the contracted seed-pod, with the attached, equally contracted, organs of fertilization, there appeared a continuation of the stalk, half red and half green, bearing in succession a number of small reddish petals with traces of anthers. Thorns could be seen appearing further up, petals half-turned into leaves, and even a number of fresh nodes from which little imperfect flowers were budding. The whole phenomenon, in all its irregularity, was one more proof for Goethe that the plant in its totality is potentially present at each point of its organism.5

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.
