Abstract: Intersubjectivity of ontology includes three trends in its development: naturalism,fideism,and aestheticism.The intersubjective philosophy of naturalism advocates concession of the subject,i.e.the concession of rational subject to that of perceptual subject or natural subject to be harmonious with the world and realize the equal association between man and the world.This is against modernity and modern core subjectivity,and is a false theoretical construction that cannot fully realize intersubjectivity.The fideism trend in naturalism intersubjective philosophy is a defect to make it an ideal theory.Intersubjectivity cannot be realized by concession of subject to be harmonious with nature;instead,it should be realized by the sublimation of subject and the world,making oneself and the world the free subjects and realizing the free association between subjects.And this is the intersubjectivity philosophy of aestheticism.

Key words: intersubjectivity, naturalism, fideism, aestheticism
