The concept of Nature

” It is an exhibition of the process of nature that each duration happens and passes. The process of nature can also be termed the “passage of nature’ . I definitely refrain at this stage from using the word ‘time’ , since the measurable time of science and of civilized life generally merely exhibits some aspects of the more fundamental fact of the passage of nature’. I believe that in this doctrine i am in full accord with Bergson , though he uses ‘time” for the fundamental fact which i call the “passage of nature”
