Only if, by means of unprejudiced observation, one has wrestled through to the recognition of this truth of the intuitive essence of thinking will one succeed in clearing the way for an insight into the psyche-physical organization of man. One will see that this organization can have no effect on the essential nature of thinking. At first sight this seems to be contradicted by patently obvious facts. For ordinary experience, human thinking makes its appearance only in connection with, and by means of, this organization. This form of its appearance comes so much to the fore that its real significance cannot be grasped unless we recognize that in the essence of thinking this organization plays no part whatever. Once we appreciate this, we can no longer fail to notice what a peculiar kind of relationship there is between the human organization and the thinking itself. For this organization contributes nothing to the essential nature of thinking, but recedes whenever the activity of thinking makes its appearance; it suspends its own activity, it yields ground; and on the ground thus left empty, the thinking appears. The essence which is active in thinking has a twofold function: first, it represses the activity of the human organization; secondly, it steps into its place. For even the former, the repression of the physical organization, is a consequence of the activity of thinking, and more particularly of that part of this activity which prepares the manifestation of thinking. From this one can see in what sense thinking finds its counterpart in the physical organization. When we see this, we can no longer misjudge the significance of this counterpart of the activity of thinking. When we walk over soft ground, our feet leave impressions in the soil. We shall not be tempted to say that these footprints have been formed from below by the forces of the ground. We shall not attribute to these forces any share in the production of the footprints. Just as little, if we observe the essential nature of thinking without prejudice, shall we attribute any share in that nature to the traces in the physical organism which arise through the fact that the thinking prepares its manifestation by means of the body.
