3. Thinking in the service of Knowledge

When we make thinking an object of observation, we add to the other observed contents of the world something which usually escapes our attention. But the way we stand in relation to the other things is in no way altered. We add to the number of objects of observation, but not to the number of methods. While we are observing the other things, there enters among the processes of the world—among which I now include observation—one process which is overlooked. Something is present which is different from all other processes, something which is not taken into account. But when I observe my own thinking, no such neglected element is present. For what now hovers in the background is once more just thinking itself. The object of observation is qualitatively identical with the activity directed upon it. This is another characteristic feature of thinking. When we make it an object of observation, we are not compelled to do so with the help of something qualitatively different, but can remain within the same element.
