Der Fremde ist uns nah, insofern wir Gleichheiten nationaler oder sozialer, berufsmäßiger oder allgemein menschlicher Art zwischen ihm und uns fühlen… - Georg Simmel

In the presence of the total reality upon which our conduct is founded, our knowledge is characterized by peculiar limitations and aberrations. We cannot say in principle that "error is life and knowledge is death," because a being involved in persistent errors would continually act wide of the purpose, and would thus inevitably perish.

Man is something that is to be overcome.
Logically considered, this, too, presents a contradiction: he who overcomes himself is admittedly the victor, but he is also the defeated. The ego succumbs to itself, when it wins; it achieves victory, when it suffers defeat. Yet the contradiction only arises when the two aspects of this unity are hardened into opposed, mutually exclusive conceptions. It is precisely the fully unified process of the moral life which overcomes and surpasses every lower state by achieving a higher one, and again transcends this latter state through one still higher. That man overcomes himself means that he reaches out beyond the bounds that the moment sets for him. There must be something at hand to be overcome, but it is only there in order to be overcome. Thus even as an ethical agent, man is the limited being that has no limit.

When one says, for example, that superiority and inferiority is a formation to be found in every human association, though the proposition certainly involves very profound insight into the essence of human nature and human relationship, yet the assertion is so general that it affords little knowledge of particular societary formations. In order to reach such particular knowledge we must study separate types of superiority and inferiority, and we must master the special features of their formation, which in proportion to their definiteness of course lose generality of application.
