I. Haeckel and His Opponents

Goethe, from his profound insight into Nature, foresaw to its full extent this revolution and its significance for the progress of man's intellectual culture. We see this particularly clearly from a conversation which he had with Soret on 2nd August, 1830. At that time the news of the beginning of the Revolution of July reached Weimar and caused general excitement. When Soret visited Goethe, he was received with the words: “Now, what do you think of this great event? The volcano has burst into eruption; all is in flames, and it is no longer a conference behind closed doors!” Soret naturally could only believe that Goethe was speaking of the July Revolution, and replied that under the known conditions nothing else could be expected than that it would end with the expulsion of the Royal family. But Goethe had something quite different in his mind. “1 am not talking of those people at all; I am concerned with quite other things. I am speaking of the conflict, so momentous for science, between Cuvier and Geoffroy de Saint-Hilaire that has come to a public outbreak in the Academy.” The conflict concerned the question whether each species in which organic nature finds expression possesses a distinct architectural plan of its own, or whether there is one plan common to them all. Goethe had already settled this question for himself forty years earlier. His eager study of the plant and animal worlds had made him an opponent of the Linnæan view, that we “count as many species as different forms were created in the beginning ( in principio).” Anyone holding such an opinion can only strive to discover what are the plans upon which the separate species are organised. He will seek above all carefully to distinguish these separate forms.
