Class interests and material conditions of existence determine ideology, and thus, in a Marxist-Leninist view, true objectivity (in terms of non-partisanship) is not possible in a society of antagonistic classes. Marxists, in Lenin's view, should openly acknowledge their partisanship on the side of proletarian revolution. Bourgeois emphasis on the normative goal of objectivity is thus considered to be delusional. In this sense, "partiinost"' is a universal and inevitable element of political and ideological life, but its presence is not always acknowledged, or is often flatly denied, by the ruling class.
