However, the discussed distinction is rejected by the majority of Western and Japanese scholars. It is contested by hermeneutic (interpretive) difficulties in the categorization of the different Taoist schools, sects and movements. Taoism does not fall under an umbrella or a definition of a single organized religion like the Abrahamic traditions; nor can it be studied as a mere variant of Chinese folk religion, as although the two share some similar concepts, much of Chinese folk religion is separate from the tenets and core teachings of Taoism. The sinologists Isabelle Robinet and Livia Kohn agree that "Taoism has never been a unified religion, and has constantly consisted of a combination of teachings based on a variety of original revelations."
