"The philosophy of praxis does not aim at the peaceful resolution of existing contradictions in history and society, but is the very theory of these contradictions. It is not the instrument of government of the dominant groups in order to gain the consent and exercise hegemony over the subaltern classes. It is the expression of subaltern classes who want to educate themselves in the art of government and who have an interest in knowing all truths, even the unpleasant ones, and in avoiding the impossible deceptions of the upper class, and even more their own."
