“五四”运动前后,中国湖南、四川等省大批知识分子出国勤工俭学,他们之中许多人先后完成了世界观的转变,实现了从民主主义到马克思主义的飞跃。蔡和森(1895年—1931年)是他们中“最早通晓马列主义的一个”。马克思主义,如列宁所说:“它给予人们一个决不同任何迷信、任何反动势力、任何为资产阶级压迫所作的辩护相妥协的完整世界观。”蔡和森思想是怎样达到这一境界的呢? Before and after the “May 4th” Movement, a large number of Chinese intellectuals in Hunan, Sichuan and other provinces went abroad for work-study programs, many of whom completed the transformation of the world outlook one after another and realized a leap from democracy to Marxism. Cai Hesen (1895-1931) was among them “one of the first to be familiar with Marxism-Leninism.” Marxism, as Lenin put it: “It gives people a complete outlook on the world that never comes down to any superstition, any reactionary force, or any defense made by the bourgeois oppression.” How did Cai think about this state?
