Vladimir Lenin,
The Three Sources and Three Component Parts of Marxism…
(1946)
“ Throughout the civilised world the teachings of Marx evoke the utmost hostility and hatred of all bourgeois science (both official and liberal) , which regards Marxism as a kind of “pernicious sect”. And no other attitude is to be expected, for there can be no “impartial” social science in a society based on class struggle. In one way or another, all official and liberal science defends wage-slavery, whereas Marxism has declared relentless war on that slavery. ”
