在瞿秋白的一生中,既对自身所犯的“左”倾错误进行了认识和纠正,又对李立三的“左”倾冒险主义进行了批判和斗争,为端正中国革命航向作出了伟大的贡献。但由于时代与历史条件的局限,他纠“左”存在着局限性与不彻底性。本文从共产国际的干预、全党的幼年性以及他自身所犯的教条主义的错误等方面,分析了其犯“左”和纠“左”不彻底性的主、客观原因。 In Qu Qiubai’s life, he not only realized and corrected the “leftist” mistakes himself committed, but also criticized and struck Li left’s “adventurism” and made great contribution to the correct direction of the Chinese revolution. However, due to the limitations of the times and the historical conditions, he rectified the “left” existence of limitations and incompleteness. This article analyzes the main objective and objective reasons for committing “leftist” and “leftist” incompleteness from the aspects of intervention by the Communist International, the juvenileity of the entire party and dogmatic errors committed by itself.
