In order to adequately understand man as "medium" it is necessary a reversal not only in the understanding of ontology, but also in the sense of the metaphysical question of the existence of being. The undeniable meaning of the exercise of thinking which Fink called a thinking back to the primary dispute between heaven and earth, becomes clear here.
The return to the meaning of the earth means the attempt to gain an insight into the wrongness of our mind. For the interpretation both of the "ontological experience" as a cosmological dialectic and of man as ens cosmologicum, the following three argumentative steps are to be carried out: 1) First we undertake the explanation of the meaning of 'being' according to Fink.
It becomes hence clear that what the metaphysical tradition, which Fink deeply criticizes, called 'ontology', can only be understood as a 'thing-ontology' or a 'regional ontology'; 2) Then we clarify why Fink understands ontology as cosmology. Here, however, questioned is the relationship established by men to being.
Fink characterizes the fact that human consciousness is no longer the privileged place where being happens with the mythical figure of Tantalus; 3) As a third and last step we present the structure of the ontological experience as an 'image', on the basis of the mediality of the image itself.
