Chapter II: The Nature of Humanity
It is characteristic both of the sentient and of the intellectual soul that they work with what is received through the impressions of sense-perceived objects and with what memory retains of these impressions. The soul is here entirely given up to things external to it. For even what it has made its own through memory,--even this was received originally from outside. But it is able to transcend all this; the soul is not only sentient and intelligent. Supersensible perception can most readily form an idea of this transcendent faculty by pointing to a simple fact, the far-reaching significance of which needs only to be rightly valued,--the fact that in the whole domain of language there is one name which differs in its essence from all other names. It is the name ‘I.’ Every other name can be given by every man to the thing or being to which it belongs. ‘I,’ on the other hand, as the designation of a being, only has meaning when the being gives itself this name. The name ‘I’ can never reach a man from without as a designation of himself. It is only to himself that any being can apply this name. ‘I’ am an *I only to myself; to every other being I* am a you, and every other being is a you to me.’
