SUMMARY
The Heideggerian metaphysical ontology aims, above all, to reconceptualise the relationship between Being and being and to relate this founding corellation to human existence. For Heideggarian analysis, the authentic school of thought of the ancient Greeks has been forgotten, discarded, with this very act, itself, being silenced. Thus, the initial concept of Being, as thought up by Plato or the pre-Socratic philosophers, was replaced with that of being, resulting in the confusion of the two. Therefore, for more than two thousand years, the tradition of Western philosophy would discuss Being, but in reality the concept at stake was that of being. The Being, as a primordial reality without which absolutely nothing can be thought and uttered, not even Nothingness itself, was excluded from the exercise of meditation, being confused with beings, with ephemeral existences, be they material or animated. While looking for answers regarding the inquiry into the nature of Being, beings were wrongly looked at. But the Being continued to manifest its luminosity, in the sense evoked by Heideggerian metaphysics, especially around man, the only being of a special type, located in the opening of the Being, (Da-Sein) which can be reoriented from beings to Being, becoming, according to Heidegger, the shepherd of Being. Only in this way does he realize that his existence is a poetic one, that is, open to the non-hiding of the Being, in the sense of Heideggerian terminology. What is this type of poetic universally-human existence, so that it does not belong only to the poet, why was it forgotten along with the Being and what danger threatens modern man through this forgetfulness evoked by Heidegger? This article aims to capture some aspects of the conceptual area of these topics.
