存在三种意义上的向乌托邦告别。从前的乌托邦主义者是马克思主义的先行者,但是乌托邦主义者缺乏中间阶段,脱离现实,不善生活。马克思主义并非不是乌托邦,而是一种具体的乌托邦的新事物。具体的乌托邦要求我们善于同可能性打交道,努力领悟可能性,使之成为一种智力参谋部,从而建设一个公正的、美好的、人道的社会。具体的乌托邦永不满足。 There are three types of farewell to utopia. Utopians of the past were Marxist forerunners, but the utopists lacked an intermediate stage to depart from reality and not be good at life. Marxism is not a utopia, but a new utopian thing. Concrete utopias demand that we be good at dealing with possibilities and trying to understand the possibilities and make them an intellectual staff to build a just, beautiful and humane society. The specific utopia will never be satisfied.
