What is the principle that makes it acceptable as a means of struggle of the revolutionary proletariat? It lies in the theory of class struggle, in the antagonistic nature of the struggle between the oppressor and the oppressed, between the exploiter and the exploited. "Force", in the words of Marx, "is the midwife of every old society pregnant with a new one", and for Engels, "is the instrument with the aid of which the social movement forces its way through and shatters the dead, fossilized political forms." As for Lenin, "in the final analysis, great historic issues are decided only by force."
Kung ang Partido ang lider ng uring manggagawa, at kung ang uring manggagawa ang lider ng sambayanan, samakatwid, ang lider ng sambayanan ay ang Partido. Ganito ang simplistiko at mekanikal na lohika ng pagiging taliba ng bayan ng Partido. Ito'y talamak na kaso ng reduksyonismo (reductionism) na tatak ng bulgar na materyalismo ng Stalinismo-Maoismo. Sinalaula nito ang tamang konsepto ng taliba, at sa dulo'y nahulog sa bisyo ng banggardismo (vanguardism).
