The article deals with the problem of the ontological content of the deconstructive hermeneutics proposed by Jacques Derrida. It is demonstrated that being, recognized as the event in the late Heideggerian ontology, in the ontological perspective of deconstruction yields its place to the post-eventual being-meaning, combining the singularity with its own absence, where being could not be conceived outside the context of the possibilities of its interpretation. The task of deconstructive ontology is not at all to invent concepts, as G. Deleuze believed, but to see the different ranges of meanings to which certain ontological concepts can be attached. In this sense, the author connects deconstruction with the modern ontological hermeneutics of Platonism. The new rethinking of Platonism, which is characterized by the works of Losev, Kolychev, Badiou, Derrida, brings us again back to the ontological dimension of Platonic terminology and constructs, according to the author, the main line of development of modern ontology. The ontological dimension of deconstruction arises in the course of making differences within the contexts of the meaning of the ontological terms of the language. In this case, we can already speak of the generation of certain meanings by the philosophical texts that create conditions for further ontological interpretation. An analysis of the sphere of these meanings constitutes the ontological content of deconstruction.
