In this article we have shown the necessity of opposing the existence as empirical, profane and the Being as transcendental, sacral, to which G. Marcel came, as well as such like-minded existential thinkers, as K. Jaspers, P. Tillich and E. Minkowski. We have shown the possibility of their unification through the notion of path and hope, proposed by Marcel. We have also shown the necessity of introducing a special “existential dimension” of reality, which Marcel placed between social and spiritual worlds. (...) In this dimension of reality, the social and spiritual factors unite in each human being in a unique way, first experienced and then manifested, embodied by him in his way of life, acts and deeds. As we have shown, if the social world exists objectively, the spiritual world doesn’t have its separate reality as in Plato’s image of ideal world outside and besides human as an exiting subject. Also we have shown, how the proposed existential dimension corresponds with three-world model of L. Binswanger and four-dimensional model of E. van Deurzen. We proposed to regard existential dimension as a level, where person acts as an existenz, while in biological dimension he acts as a phisical body, in social – he acts as social function, and in spiritual dimension he acts as a personality.
