“问题与主义”之争涉及马克思主义与实验主义之间的最初冲突。虽然李大钊与胡适在论战中各自表达了不同的哲学与社会政治思想,但是这种冲突具有“原初”性质;在李大钊的“根本解决”与胡适的“点滴改良”之间存在着可以沟通的环节;李大钊与胡适的关系表明,中国革命可以在原则的坚定性和策略的灵活性之间保持“必要的张力”。 The “issue and doctrine” debate involves the initial clashes between Marxism and experimentalism. Although Li Dazhao and Hu Shi each expressed different philosophical and social political thoughts in the controversy, this kind of conflict has the nature of “primitiveness.” There is a communicable link between Li Dazhao’s “fundamental solution” and Hu Shih’s “trickery improvement” The relationship between Li Dazhao and Hu Shi shows that the Chinese revolution can maintain the “necessary tension” between the firmness of principles and the flexibility of tactics.
