But in fact there is no circle at all in the formulation of our question. Beings can be determined in their being without the explicit concept of the meaning of being having to be already available. If this were not so there could not have been as yet any ontological knowledge. And probÂably no one would deny the factual existence of such knowledge. It is true that "being" is "presupposed" in all previous ontology, but not as an available concept-not as the sort of thing we are seeking.
