Man's position in the world is defined by the fact that in every dimension of his being and behavior he finds himself at every moment between two bou… - Georg Simmel

The Stranger is close to us, insofar as we feel between him and ourselves common features of a national, social, occupational, or generally human, nature. He is far from us, insofar as these common features extend beyond him or us, and connect us only because they connect a great many people.

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.

Der Fremde ist uns nah, insofern wir Gleichheiten nationaler oder sozialer, berufsmäßiger oder allgemein menschlicher Art zwischen ihm und uns fühlen; er ist uns fern, insofern diese Gleichheiten über ihn und uns hinausreichen und uns beide nur verbinden, weil sie überhaupt sehr Viele verbinden.
