作为德国社会民主党与第二国际的左派代表，罗莎·卢森堡是国际共运史上一位较 有争议的重要人物。尽管她长期备受质疑，但是在保障党内外的言论自由上，卢森堡的 主张与马克思、恩格斯是一致的。与列宁不同，卢森堡不仅在工人政党夺取政权前就积 极争取言论自由，而且在工人政党夺取政权后仍然反对压制和取消党内外言论自由的做 法，坚决捍卫广大党员和社会大众的基本权利，并努力恪守“自由始终是持不同思想者 的自由”的理念。

As a Marxist theorist and representative of the leftist of The Second International and the Social Dy of the international communist movement. Although had been questioned in a long time, she agreed with Karl Marx and Friedrich Engels on the issue of freedom of the speech within the party. Unlike Lenin, however,Luxemburg actively fought for the freedom of speech before workers' party took power, but also advocated press freedom within and outside the party even after that, and strived to stick to the concept of “freedom is always and exclusively freedom for the one who thinks differently”.
