By acting as a mediator between universal knowledge produced by man and the student, who possesses knowledge that does not safely transcend the barriers of common sense, who observes reality as static, who does not carry with them the notion of the historicity of things, and who therefore possesses an alienated state of consciousness, the educator plays a revolutionary role. The maintenance of the proletariat as a class, which carries with it the historical mission of destroying the capitalist system, is one of the functions performed even by educators affiliated with traditional pedagogy. The transformation of consciousness itself into consciousness for itself, into transformative consciousness, is the second function of the educator, which can only be performed through historical-critical pedagogy.
