On the ontological structure of dasein.

...what is customarily called transcendence in philosophy? It is commonly taught in philosophy that what is transcendent is things, objects. But what is originally transcendent, what does the transcending, is not things as over against the Dasein: rather, it is the Dasein itself which is transcendent in the strict sense. Transcendence is a fundamental determination of the ontological structure of the Dasein. It belongs to the existentiality of existence. Transcendence is an existential concept.
