[Lenin] advanced philosophy in so far as he had advanced political doctrine and practice. The realisation [sic] of an apparatus of hegemony, in so far as it creates a new ideological soil and determines a reform of consciousness and of the methods of knowledge, is a fact of knowledge, a philosophical fact.

In Crocean language: when we succeed in introducing a new morality in conformity with a new conception of the world, we end up by introducing that conception of the world too, so that an entire reform of philosophy is brought about (QC, 1249-50; PN, 365-66). ~Antonio Gramsci
