Existential tradition provides at least two lines of development of the problem: the first line is created as a return to true existence by the abandonment of mediocre communication; The second line emphasizes the doom of a collision with the Other, in which the latter is one of the stages in the formation of self-consciousness. The actuality of the study is due to the need for the integration of these two models, refuting the widespread opinion on existentialism as the apology of complete decline, decadence, solipsism, human passivity, and, finally, the unnecessity of philosophical act in the state of complete neglect of the subject, as well as the conditions of homelessness of their own being. We will move in a logical way, which can be schematically represented in the form of a parabola: from the phenomenological macro level (J.-P. Sartre) to ambiguity, curiosity, reminiscences of everyday We, and through the ontologization of the latter to the problem of existence (M. Heidegger), of course, in the existential interpretation of it. We will be interested not only in the potential of language transformational processes in a certain field of philosophy, but also in parallel with their real incarnations in what we call the phenomenon of postmodern, full of the consequences of the Heideggerian view of language in its distorted variation (J. Derrida). The purpose of the study is to establish alternatives in the coordinates of the essence of existence-communication through overcoming both “atomicity” and “totalitarianism” of the subject on the basis of philosophical and existential principles.
