Existential is a form, way, and type of human existence. Kierkegaard, Heidegger, Sartre emphasized the negative mood - «anxiety», «concern», «fear», «death». This is due to an era of emergencies and, above all, the wars. But in an era of prosperity philosophers continued to talk about alienation, the violation of human rights, and of conformism and loneliness. However, in the postmodern era, youth protests and deconstruction of intellectuals and the actions of avant-garde artists were a game, which more often had no consequences. However, black discourse on man and society remains dominant, perhaps as a premonition of impending disasters. Therefore, at least in protest, it should be recalled the positive attitudes associated with the belief that modernity offers possibilities to live a better life.
