The present part of our discussion may be concluded by the introduction of a concept which Goethe formed for the organ of cognition attained through contemplating nature in the state of becoming, as the plant had taught him to do.

Stage by stage the type expends itself in ever more elaborate forms of appearance, until in the blossom a triumph of form over matter is reached. A mere continuation of this path could lead to nothing but a loss of all connexion between the plant's superphysical and physical component parts. Thus, to guarantee for the species its continuation in a new generation, the formative power of the type must find a way of linking itself anew to some part of the plant's materiality. This is achieved by the plant's abandoning the union between its two polar growth-principles and re-establishing it again, which in the majority of cases takes place even in such a way that the bearers of the two principles originate from two different organisms.

Wolff had risen up as an opponent of the so-called preformation theory, still widespread at that time, according to which the entire plant with all its different parts is already present in embryonic physical form in the seed, and simply grows out into space through physical enlargement. Such a mode of thought seemed inadmissible to Wolff, for it made use of an hypothesis 'resting on an extra-sensible conception, which was held to be thinkable, although it could never be demonstrated from the sense world. Wolff laid it down as a fundamental principle of all research that 'nothing may be assumed, admitted or asserted that has not been actually seen and cannot be made similarly visible to others'. Thus in Wolff we meet with a phenomenologist who in his way tried to oppose certain trends of contemporary biological thinking. As such, Wolff had made certain observations which caused him to ascribe to the plant features quite similar to those which Goethe had grasped under the conception of progressive and regressive metamorphosis. In this way Wolff had grown convinced that all plant organs are transformed leaves. True to his own principle, he had then turned to the microscope for his eyes to confirm what his mind had already recognized.

⁸ 'Exakte sinnliche Phantasie.'

In 1790, a year before Galvani's monograph, Concerning the Forces of Electricity, appeared, Goethe published his Metamorphosis of Plants, which represents the first step towards the practical overcoming of the limitations of the onlooker-consciousness in science. Goethe's paper was not destined to raise such a storm as soon followed Galvani's publication. And yet the fruit of Goethe's endeavours is not less significant than Galvani's discovery, for the progress of mankind. For in Goethe's achievement lay the seed of that form of knowing which man requires, if in the age of the electrification of civilization he is to remain master of his existence.

In the scientific work of Goethe his botanical studies have a special place. As a living organism, the plant is involved in an endless process of becoming. It shares this characteristic, of course, with the higher creatures of nature, and yet between it and them there is an essential difference. Whereas in animal and man a considerable part of the life-processes conceal themselves within the organism, in order to provide a basis for inner soul processes, the plant brings its inner life into direct and total outer manifestation. Hence the plant, better than anything, could become Goethe's first teacher in his exercise of re-creating nature.

By pursuing in this way the living doing of the plant from stage to stage we become aware of a significant rhythm in its total life cycle. This, when first discovered by Goethe, gave him the key to an understanding of nature's general procedure in building living organisms, and in maintaining life in them.

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

Let us look back once again on the way in which we first tried to build up the picture of leaf metamorphosis. There we made use, first of all, of exact sense-perceptions to which we applied the power of memory in its function as their keeper. We then endeavoured to transform within our mind the single memory pictures (leaf forms) into one another. By doing so we applied to them the activity of mobile fantasy. In this way we actually endowed, on the one hand, objective memory, which by nature is static, with the dynamic properties of fantasy, and, on the other hand, mobile fantasy, which by nature is subjective, with the objective character of memory. Now, for the new organ of cognition arising from the union of these two polar faculties of the soul, Goethe coined the significant expression, exact sensorial fantasy.⁸ In terms of our knowledge of man's psycho-physical make-up, acquired earlier, we can say that, just as the nervous system forms the basis for memory, and the blood the basis for fantasy, so the 'exact sensorial fantasy' is based on a newly created collaboration of the two.

By picturing the process in this way we are brought face to face with a rule of nature which, once we have recognized it, proves to hold sway at all levels of organic nature. In general terms it may be expressed as follows:
