The True Naturalism.

But naturalism becomes fundamentally different when it ceases to remain at the level of naïve or fancifully conceived ideas of “nature” and “natural occurrences,” when, instead of poetry or religious sentiments, it incorporates something else, namely, exact natural science and the idea of a mathematical-mechanical calculability in the whole system of nature. “Nature” and “happening naturally”, as used by the naïve intelligence, are half animistic ideas and modes of expression, which import into nature, or leave in it, life and soul, impulse, and a kind of will. And that speculative form of naturalism which tends to become religious develops this fault to its utmost. But a “nature” like this is not at all a possible subject for natural science and exact methods, not a subject for experiment, calculation, and fixed laws, for precise interpretation, or for interpretation on simple rational [pg 023] principles. Instead of the naïve, poetical, and half mystical conceptions of nature we must have a really scientific one, so that, so to speak, the supernatural may be eliminated from nature, and the apparently irrational rationalised; that is, so that all its phenomena may be traced back to simple, unequivocal, and easily understood processes, the actual why and how of all things perceived, and thus, it may be, understood; so that, in short, everything may be seen to come about “by natural means.”

There is obviously one domain and order of processes in nature which exactly fulfils those requirements, and is really in the fullest sense “natural,” that is, quite easily understood, quite rational, quite amenable to computation and measurement, quite rigidly subordinate to laws which can be formulated. These are the processes of physics and chemistry, and in a still higher degree those of movement in general, the processes of mechanics in short. And to bring into this domain and subordinate to its laws everything that occurs in nature, all becoming, and passing away, and changing, all development, growth, nutrition, reproduction, the origin of the individual and of the species, of animals and of man, of the living and the not living, even of sensation and perception, impulse, desire and instinct, will and thought—this alone would really be to show that things “happen naturally,” that is, to explain everything in terms of natural causes. And the conviction that this can be done is the only true naturalism.

Naturalism of this type is fundamentally different in mood and character from the naïve and poetic form, and is, indeed, in sharp contrast to it. It is working against the very motives which are most vital to the latter—namely, reverence for and deification of nature. Where the two types of naturalism really understand themselves nothing but sharp antagonism can exist between them. Those on the one side must condemn this unfeeling and irreverent, cold and mathematical dissection and analysis of the “Great Goddess” as a sacrilege and outrage. And those on the other side must utterly reject as romantic the view which is summed up in the confession: “Ist nicht Kern der Natur Menschen im Herzen?” [Is not the secret of nature in the human heart?]

Goethe's Attitude to Naturalism.

The most instructive example we can take is Goethe: his veneration for nature on the one hand, and on the other his pronounced opposition to the naturalism both of the materialists and of the mathematicians. Modern naturalists are fond of seeking repose and mental refreshment in Goethe's conception of the world, under the impression that it fits in best and most closely with their own views. That they do this says much for their mood and taste, but not quite so much for their powers of discrimination or for their consistency. It is even more thoughtless than when the empiricists [pg 025] and sensationalists acclaim as their hero, Spinoza, the strict, pure rationalist, the despiser of empiricism and of knowledge acquired through the senses. For to Goethe nature is far from being a piece of mechanism which can be calculated on and summed up in mathematical formulæ, an everlasting “perpetuum mobile,” a magnificent all-powerful machine. In fact, all this and especially the word “machine” expresses exactly what Goethe's conception was most directly opposed to. To him nature is truly the “Goddess,” the great Diana of the Ephesians, the everlasting Beauty, the artist of genius, ceaselessly inventing and creating, in floods of Life, in Action's storm—an infinite ocean, a restless weaving, a glowing Life. Embracing within herself the highest and the humblest, she is in all things, throughout all change and transformation, the same, shadowing forth the most perfect in the simplest, and in the highest only unfolding what she had already shown in the lowliest. Therefore Goethe hated all divisions and rubrics, all the contrasts and boundaries which learned analysis attempts to introduce into nature. Passionately he seized on Herder's idea of evolution, and it was towards establishing it that all his endeavours, botanical, zoological, morphological and osteological, were directed. He discovered in the human skull the premaxillary bone which occurs in the upper jaw of all mammals, and this “keystone to man” gave him, as he himself said, “such joy that all his bowels moved.” He interpreted the skull as developed [pg 026] from three modified vertebræ. He sketched a hypothesis of the primitive plant, and the theory that all the organs of the plant are modifications and developments of the leaf. He was a friend of Etienne Geoffroy St. Hilaire, who defended “l'unité de composition organique” in the forms of nature, and evolution by gradual stages, and he was the vehement opponent of Cuvier, who attempted to pick the world to pieces according to strictly defined architectural plans and rigid classes. And what the inner impulse to all this was he has summed up in the motto to his “Morphology” from the verse in Job:

Lo, he goeth by me, and I see him not;
