Abstract EN:

Heidegger's thought, white beinq strictly philosophical, explicietely implies a debate with poetry, especially holderlin's one, in order to legitimate its owen project. This detour via anotjer means of expression, the refore, should he explained in its meaning and inner necessity. It implies a radical subversion of the relationship to language, a deconstruction of metaphysical structures and grammar, but also a reevaluation of the status of the work of art in its foundations, with all the political consequences that a fundamental ontology can bring. Poetry reduced to the only name of holderlin isgiven the task of a foundation of being, but this violent identification (meaning, proper name, and textuality) leads, in its very legitimacy, to a necessary failure. In the last chapters, the limits of this poetics are drawn : the essence of modern technology as freedom, and the nature of the event (ereignis) are the two opposite possibilities on the heideggerian pathway in the posfmodern era.
