I. Haeckel and His Opponents

Now, however, it is urged from the side of philosophy that the means at the disposal of science are insufficient to establish a world-conception. From its own standpoint science was entirely right in explaining the whole world-process as a chain of causes and effects, in the sense of a purely mechanical conformity to law; but behind these laws, nevertheless, there is hidden the real cause, the universal world-reason, which only avails itself of mechanical means in order to realise higher, purposeful relations. Thus, for instance, Arthur Drews, who follows in the path of Eduard von Hartmann, observes: “Human works of art, too, are produced in a mechanical manner, that is when one looks only at the outward succession of single moments, without reflecting on the fact that after all there is hidden behind all this only the artist's thought; nevertheless one would rightly take that man for a fool who would perchance contend that the work was produced purely mechanically ... that which presents itself as the inevitable effect of a cause, on that lower standpoint which contents itself with merely gazing at the effects and thus contemplates the entire process as it were from behind, that very same thing reveals itself, when seen from the front, in every case as the intended goal of the means employed” ( German Speculation since Kant, vol. ii, p. 287 et seq.). And Eduard von Hartmann himself remarks about the struggle for existence which renders it possible to explain living creatures naturally: “The struggle for existence, and therewith the whole of natural selection, is only the servant of the Idea, who is obliged to perform the lower services in its realisation, namely, the rough hewing and fitting of the stones that the master-builder has measured out and typically determined in advance according to their place in the great building. To proclaim this selection in the struggle for existence as the essentially adequate principle of explanation of the evolution of the organic kingdom, would be on a par with a day-labourer, who had worked with others in preparing the stones in the building of Cologne Cathedral, declaring himself to be the architect of that work of art” ( Philosophy of the Unconscious, 10th ed., vol. iii, p. 403).
