Abstract: In the post-academic age， the scientific community is deeply rooted in the network of social practices， challenging the spirit of science under the Merton paradigm. The main body of the scientific community is prone to instrumental rationality while withdrawing from value rationality. The independent spirit of science tends to weaken and the awareness of social responsibility is lacking， which lead to the crisis of scientific ethics. In the post-academic age， a possible way out of the crisis of scientific ethics lies in integrating the independent spirit and social value of science， actively promoting the interaction between the main body of the scientific field and the social field， and carrying out moral negotiations among the subjects in different contexts based on communicative practice so as to enhance the social responsibility awareness and facilitate the moral consensus in the scientific community.

Key words: post-academic science, scientific community, instrumental rationality, value rationality, moral consensus
