3-6RATIONALISM (Taurus)
[17] This transparent clearness concerning our thinking process is quite independent of our knowledge of the physiological basis of thinking. Here I am speaking of thinking in so far as we know it from the observation of our own spiritual activity. How one material process in my brain causes or influences another while I am carrying out a thinking operation, is quite irrelevant. What I observe about thinking is not what process in my brain connects the concept lightning with the concept thunder but what causes me to bring the two concepts into a particular relationship. My observation shows me that in linking one thought with another there is nothing to guide me but the content of my thoughts; I am not guided by any material processes in my brain. In a less materialistic age than our own, this remark would of course be entirely superfluous. Today, however, when there are people who believe that once we know what matter is we shall also know how it thinks, we do have to insist that one may talk about thinking without trespassing on the domain of brain physiology. Many people today find it difficult to grasp the concept of thinking in its purity. Anyone who challenges the description of thinking which I have given here by quoting Cabanis' statement that "the brain secretes thoughts as the liver does gall or the spittle-glands spittle . . .", simply does not know what I am talking about. He tries to find thinking by a process of mere observation in the same way that we proceed in the case of other objects that make up the world. But he cannot find it in this way because, as I have shown, it eludes just this ordinary observation. Whoever cannot transcend materialism lacks the ability to bring about the exceptional condition I have described, in which he becomes conscious of what in all other spiritual activity remains unconscious. If someone is not willing to take this standpoint, then one can no more discuss thinking with him than one can discuss color with a blind man. But in any case he must not imagine that we regard physiological processes as thinking. He fails to explain thinking because he simply does not see it.
