"Now Marxist sociology, covering a huge material of empirical research, is increasingly becoming a concrete science about society, the laws of its development and functioning. In this process, despite the importance of the content of the study, mathematical research methods are of particular importance. Mathematics in this case acts as a kind of logical "filter"; by passing through it specific sociological studies, you can decisively cut off everything that has nothing to do with practice or theory. And only what will pass through this "filter" should, in our opinion, be laid in the foundation of science."
