Abstract:The “unlimited expansion” and “organized irresponsibility” of modern industrial society are bound to push us from world risk society into the post-world risk society. COVID-19 has been rapidly sweeping the world, pushing humans into the post-world risk society. Political mobilization to resist risks will rise above geographical borders because post-world risks come not only from human society, politics, and technology, but also from the environment, nature, species, and the limitation and history of human beings. Therefore, time and space are co-existent: time creates space, and space opens for time, which results in uncontrollable self-action and “government failure”. To get out of the post-world risk society characterized by post-environmental risks, post-technical risks, post-epidemic risks, and post-political-economic risks, it is necessary to review the utilitarian globalization, the pacemaker of modernization, so as to relieve the anxiety of the post-world risk society, guide the ecology in the post-risk era to rationally confront the omnipresent uncertainty, move towards a new world union, and rebuild a symbiotic civilization. Basically, we need to make efforts to reconstruct our cognition of existence about the “universal existence of man”, “the legislation of nature for man”, and “limited existence”. Guided by the symbiotic existence of "nature, society and human beings" and driven by sympathy and understanding, we will explore the action principle for symbiosis and co-governance, and rebuild the framework and action mode for symbiosis and co-governance.
