III. Thinking in the Service of Understanding the World

This transparent clarity of the process of thinking is quite independent of our knowledge of the physiological basis of thinking. I speak here of thinking insofar as it presents itself to observation of our spiritual activity. How one material process in my brain causes or influences another while I carry out a line of thought, does not come into consideration at all. What I see when I observe thinking is not what process in my brain connects the concept of lightning with the concept of thunder, but I see what motivates me to bring the two concepts into a particular relationship. My observation of thinking shows me that there is nothing that directs me in my connecting one thought with another, except the content of my thoughts; I am not directed by the material processes in my brain. In a less materialistic age than ours this remark would of course be entirely superfluous. Today however, when there are people who believe: When we know what matter is, we shall also know how matter thinks,—it has to be said that it is possible to speak about thinking without entering the domain of brain physiology at the same time. Today many people find it difficult to grasp the concept of thinking in its purity. Anyone who wants to contrast the representation of thinking I have here developed, with Cabanis[^2] statement, “The brain secretes thoughts as the liver does gall or the spittle-glands spittle, etc.,” simply does not know what I am talking about. He tries to find thinking by means of a mere process of observation such as we apply to other objects that make up the content of the world. He cannot find it in this manner because as I have shown, it eludes normal observation. Whoever cannot overcome materialism lacks the ability to bring about in himself the exceptional situation described above, which brings to his consciousness what remains unconscious in all other spiritual activities. If a person does not have the good will to place himself in this situation, then one can no more speak to him about thinking than one can speak about color to a person who is blind. However, he must not believe that we consider physiological processes to be thinking. He cannot explain thinking because he simply does not see it.
