革命的政治家们，懂得革命的政治科学或政治艺术的政治专门家们，他们只是千千万万的群众政治家的领袖，他们的任务在于把群众政治家的意见集中起来，加以提炼，再使之回到群众中去，为群众所接受，所实践，而不是闭门造车，自作聪明，只此一家，别无分店的那种贵族式的所谓“政治家”，——这是无产阶级政治家同腐朽了的资产阶级政治家的原则区别。 Revolutionary statesmen, the political specialists who know the science or art of revolutionary politics, are simply the leaders of millions upon millions of statesmen -- the masses. Their task is to collect the opinions of these mass statesmen, sift and refine them, and return them to the masses, who then take them and put them into practice. They are therefore not the kind of aristocratic "statesmen" who work behind closed doors and fancy they have a monopoly of wisdom. Herein lies the difference in principle between proletarian statesmen and decadent bourgeois statesmen.
