III. Thinking in the Service of Understanding the World
I am even in the same position when I let the exceptional situation come about and think about my own thinking. I can never observe my present thinking, but only afterward can I make into an object of thinking the experience I have had of my thinking-process. If I wanted to observe my present thinking, I would have to split myself into two persons: one to do the thinking, the other to observe this thinking. This I cannot do. I can only accomplish it in two separate acts. The thinking to be observed is never the one actually being produced, but another one. Whether for this purpose I observe my own earlier thinking, or follow the thinking process of another person, or else, as in the above example of the movements of the billiard balls, presuppose an imaginary thinking process, makes no difference.
