M. Heidegger’s philosophy of langue and word as an ontological object

The aim of the study is to identify the role and meaning of langue and word in the ontological perspective of the interrogation of entity in Heideggerian philosophy, where the history of entity and verity are inextricably linked to the history of language, in which, in fact, the verity of being is manifested. A comprehensive analysis of the distinction between the existential language, which ascends to metaphysics and is linked to an existential ontology, and the language of being, which is accessible to onto-hermeneutic listening, is carried out in this paper. The authors come to the conclusion that the subject-object opposition and the theory of truth based on it as the correspondence of the subject’s images to the object of reality are inextricably linked with each other and determine the processes of language deontologization. With the subject-object opposition, being leaves both the signifier and the signified (thing): the word “subsist” has nothing to signify, because there is no subject to which it can point. In the subject-object opposition, subsistence is given only the role of sign without meaning, giving rise to an ontohermeneutic criticism that seeks to give langue and word an ontological aspect again.
