Chapter II: The Nature of Humanity
In the spiritual soul the real nature of the *I first becomes revealed. For while in sentient and intellectual activity the soul is given up to other things, qua spiritual soul it seizes hold of its own being. Hence too, the spiritual soul can only perceive the I by dint of a certain inner activity. The mental images and representations of external objects are formed as these objects come and go; in the intellect they go on working by their own impetus. But if the I is to perceive itself, it can no longer passively devote itself to other things. To become conscious of its own essence and being, it must first call it forth—by dint of inner activity—out of the depths of its own nature. With the perception of the ‘I’—with self-contemplation—an inner activity of the I itself begins. By virtue of this activity, the perception of the I* in the spiritual soul has a fundamentally different significance for man from the observation of what comes to him through the three bodily members and the other two members of the soul.
