本文是日本学者沟口雄三与中国学者孙歌对“知识共同体”话题进行的一次对话。“知识共同”的特征是对于当下具体问题持有的不满足感和批判精神,它不仅仅是向外的,通常也是指向自身,包含着自我批判和自我否定的精神。 This article is a dialogue between the Japanese scholar Mizoguchi and the Chinese scholar Sun Ge on the topic of “knowledge community.” The characteristic of “common knowledge” is the sense of dissatisfaction and critical spirit held for the specific problems of the present. It is not only outward but also usually directed toward itself, embodying the spirit of self-criticism and self-denial.
