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

To help towards a clear understanding of both tendencies, Goethe describes an exercise which is characteristic of his way of schooling himself in what he called exact sensorial fantasy. He first looks out for a phenomenon in which the 'secret' of the spiral tendency is made 'open'. This he finds in such a plant as the convolvulus; in this kind of plant the vertical tendency is lacking, and the spiral principle comes obviously into outer view. Accordingly, the convolvulus requires an external support, around which it can wind itself. Goethe now suggests that after looking at a convolvulus as it grows upwards around its support, one should first make this clearly present to one's inner eye, and then again picture the plant's growth without the vertical support, allowing instead the upward-growing plant inwardly to produce a vertical support for itself. By way of inward re-creation (which the reader should not fail to carry out himself) Goethe attained a clear experience of how, in all those plants which in growing upwards produce their leaves spiral-wise around the stem, the vertical and spiral tendencies work together.

Goethe's approach to his conception of the type is clear evidence that he did not undervalue the factor of adaptation as a formative element in nature; we have seen that he became acquainted with it in studying the same plant species under different climatic conditions. In his view, however, adaptation appears not as the passive effect of a blindly working, external cause, but as the response of the spiritual type to the conditions meeting it from outside.

We remember that, to form this faculty, two existing functions of the soul, as such polarically opposite, had to be welded together - memory based on exact sense-perception and the freely working fantasy; one connected with the nervous system of the body, the other with the blood. We also know from earlier considerations (Chapter II) that in the little child there is not yet any such polarization, in body or soul, as there is in man's later life. Thus we see that training on Goethe's lines aims at nothing less than restoring within oneself a condition which is natural in early childhood.

This agreement between Kant and Hume must at first sight surprise us, when we recall that, as already mentioned, Kant worked out his philosophy precisely to protect the cognizing being of man from the consequences of Hume's thought. For, as he himself said, it was his becoming acquainted with Hume's Treatise that 'roused him out of his dogmatic slumber' and obliged him to reflect on the foundations of human knowing. We shall understand this apparent paradox, however, if we take it as a symptom of humanity's close imprisonment in recent centuries within the limits of its onlooker-consciousness.

In the next leaf we find this process still further advanced. The large incisions have almost reached the centre, while a number of smaller ones at the periphery have also grown deeper into the leaf. The basic plan of the total leaf is still maintained, but the negative forms have so far got the upper hand that the original roundness is no longer obvious.

In this 'climbing up the spiritual ladder' Goethe learned to recognize one of nature's basic principles. He termed it Steigerung (heightening). Thus he saw the plant develop through Metamorphosis and Heightening towards its consummation. Implicit in the second of these two principles, however, there is yet another natural principle for which Goethe did not coin a specific term, although he shows through other utterances that he was well aware of it, and of its universal significance for all life. We propose to call it here the principle of Renunciation.

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.

In following the two growth-principles, Goethe saw that the vertical comes to a halt in the blossom; the straight line here shrinks together, so to say, into a point, surviving only in the ovary and pistil as continuations of the plant's stalk. The spiral tendency, on the other hand, is to be found in the circle of the stamens arranged around these; the process which in the leaves strove outwards in spiral succession around a straight line is now telescoped on to a single plane. In other words, the vertical-spiral growth of the plant here separates into its two components. And when a pollen grain lands on a pistil and joins with the ovule prepared in the ovary, the two components are united again. Out of the now complete seed a new and complete plant can arise.

The same applies to the concept of inheritance. Through inheritance Goethe saw single, accessory characteristics of a species being carried over from one generation to the next; but never could the reappearance of the basic features of the species itself be explained in this way. He was sufficiently initiated into nature's methods to know that she was not in need of a continuity of the stream of physical substance, in the sense of the theory of inheritance, to guarantee a continuance of the features of the species through successive generations, but that it was her craft to achieve such continuance by means of physical discontinuity.
