The term 教条主义 is not just a philosophical concept in China; it's a politically charged accusation with deep historical weight. Its prominence comes directly from the internal debates of the Communist Party of China (CPC). In the 1930s and 40s, Mao Zedong fiercely criticized what he saw as 教条主义 within the party. He argued that some party members were trying to mechanically copy the model of the Russian Revolution and apply Marxist-Leninist texts literally, without adapting them to China's unique “national conditions” (国情 guóqíng). His famous essays “On Practice” (实践论) and “Oppose Book Worship” (反对本本主义) are direct attacks on this mindset. He championed the idea of 实事求是 (shí shì qiú shì)—seeking truth from facts—as the antidote.
While its origins are political, 教条主义 is now used more broadly to criticize inflexibility in various domains. The connotation is always strongly negative.
