Both ways of looking on man are constantly needed. We might alternate between them in any experience. In the heat of argument, my friend will certainly be for me the subject with whose meanings I try to agree or disagree, whose emotions carry me away, whose ideas open the world to me. Yet in the next moment, I may notice that his ideas were shaped and determined by certain earlier experiences; that they linked themselves in memory according to certain laws of mental flow; that the vividness of his ideas made him overlook certain impressions of the surroundings; and that may turn my attention to an entirely different aspect of his inner life. His feelings and emotions, his volitions and judgments now have for me simply the character of processes which go on and which are observed, which coincide and which succeed each other, which fuse and overlap, and which are composed of smaller parts. My interest is now no longer in the meaning and intentions of this self, but it belongs to the structure and the connections in this system of mental facts. At first, I wanted to understand him by living with him, by participating in his attitudes, and by feeling with his will; now I want to understand him by examining all the processes which go on in his consciousness, by studying their make-up and their behavior, their elements and their laws. In one case I wanted to interpret the man, and finally to appreciate him; in the other case I wanted to describe his inner life, and finally to explain it. The man whose inner life I want to share I treat as a subject, the man whose inner life I want to describe and explain I treat as an object.
