Abstract: To think about the environmental philosophy in the global public health crisis from a more far-reaching spiritual level, whether it can be further developed in the post-epidemic era, has the following three aspects of analytical outlook. First, to wake up the "crisis challenge" with "the opportunity of environmental philosophy"; Second, "the concept certainty of environmental philosophy" is used to offset "the uncertainty of crisis"; Third, "increment of environmental philosophy" is used to overcome "the stock of crisis". Looking at the development of environmental philosophy in the new era, it shows the positive application of dialectics of nature in philosophical thinking of a series of social problems; moreover, it reflects the multi-dimensional intersection of the theoretical connotation of environmental philosophy with natural philosophy and ecological philosophy. If human beings can get out of the wrong way in the changeable world situation, it will not only always seek the evidence from environmental philosophy, but also needs to forge a clear epistemology to support the value shift of polycentric thoughts.
