Nikolai Berdyaev and Pitrim Sorokin did not fit into traditional historiography of their times, they were outside the scope of research standards, they strived to reveal the nature and objective laws of the revolution, and take a look into the future. Berdyaev studied Russian civilization and revolution as a spiritual phenomenon he revealed religious basics and limitations of the phenomenon. Sorokin studied fluctuations from the sociological view. In this light he, in the same way as Berdyaev, researched beyond an individual and particular act. Conversion of qualitative variables into quantitative ones let him construct a diagram of the process, it European and world dynamics. Berdyaev and Sorokin studied riots differently but agreed on the main thing – a revolution is integral to society existence and breaks out when the system of social and cultural values is ruined.
