On Two Value Systems in Laozi

It is reasonable,to some extent,that most former researchers are inclined to the belief that Laozi established naturalism value system with Dao as its core.But the comprehensive view of Laozi may show that this system isn't thoroughly displayed in the book.Although it has lost personalism,sky still has strong telesis and moral authorization,which embodies the Laozi's thought and forms his idealism value system with sky as its core.But this point is neglected by the former researchers.
