I. Natural Science and Its Boundaries

We are also equipped with a sense that extends over the whole of our body: we can call it the sense for the perception of the Ego of another person. In this connection even philosophy has become childish in the modern age, for to-day one can, for example, often hear it argued: We meet another person; we see that he has a human form like our own, and because we know that as human beings we are endowed with an Ego, we conclude, as it were by subconscious inference, that he too must have an Ego within him. This is quite contrary to the psychological reality. A genuine observer knows that it is a direct perception, not an inference drawn from analogy, through which we perceive the Ego of the other person. There is really only one man—a friend or associate of the Göttingen school of Husserl, Max Scheeler by name—who has hit upon this direct perception of the Ego of another person.
