Abstract: Marxist historical materialism thinks that the time spirit is a kind of civilized consciousness to reflect and promote socialization of production and equalization of society.It has clear-cut characteristic of the times and important significance for the social democratism to look on freedom,justice and interdependence as value principle core of its zeitgeist.But it disobeys the fundamental principle of scientific socialism and has not fundamentally denied the capitalist system.Therefore,it is in essence a reformative capitalism.
