Now, the first movement of opposition is produced in just that sphere which seemed Naturalism's strongest bulwark, that is, Natural Science, the Natural Science based on mathematics and physics. Only the most fleeting survey can lead to the confusion of Natural Science with Naturalism; in reality, the naturalistic thinker cannot with justice acknowledge any exact Natural Science, and a natural scientist cannot be naturalistic in thought in consequence of his science, but only in spite of it. For, Natural Science is anything but a mere copy of the sense impressions which we experience; its origin and progress are due to the fact that thought fundamentally acts upon and transforms those impressions. If our intellect were no more than Naturalism can logically make it out to be, it could, at most, only refine the animal presentations a little; it never could have advanced beyond the single presentations to a representative conception of the world as a whole. Such an advance can be achieved only by thought raising itself above the stream of appearances and placing itself over against it; but how could a mere bundle of perceptions, to which Naturalism reduces the intellect, achieve this? Incomparably more unity of being and freedom of operation are necessary for this achievement than such a bundle could produce. In earlier times, no doubt, man went very much astray in the interpretation of his environment; he transferred his immediate feelings into it; he coloured the whole world in human colours, and associated with its realities as with beings of the same nature as himself. But even the error shows a seeking and an interpretation; the simple putting of the question proclaims a being becoming superior to mere nature. The most important thing, however, is that man has not regarded the matter as finally settled with this anthropomorphism; he has come to regard it as inadequate and has pressed forward to a new way of thinking. What could drive him to that change but a desire for truth, and how is such a conception as _truth_ attainable from nature? And if thought has succeeded in breaking through the misty veil of anthropomorphism and seeks things in their own relations; if an objective consciousness of the world has emerged, a consciousness which is as different from the immediacy of sense impressions as the sky is distant from the earth, has not man also grown in himself beyond mere sense impression; is it not a work of thought which supports and governs the whole construction, and differentiates genuine nature from appearance? How much power of comprehension and of relating together is exhibited even by Natural Science, in that it analyses the sense presentation of the environment into its single elements, ascertains the laws of these, and traces the movement from the simplest beginnings right up to its present stage of development. All activity of thought is thus subject to a certain
