The study analyses three realities in which human lives: empirical, socio-cultural, and existential. The research shows that human exists in different realities and understand them with different psychological grounding. Common meaning for all the people, not individual personal meaning, acts as a psychological basis for understanding of judgments about the facts of empirical reality. In this case understanding is based on commonly known authentic knowledge which M. Foucault called «cognitive», not converting the subject understanding the world.
