Therefore, in Europe in the latter half of the 19th century, the term of Tao-ism was created for indicating both of the religions, and a French academic school, headed by Henry MASPERO, went as far as to point to a causal relationship between the two religions.
そのため西欧では、19世紀後半に両方を指す語としてタオイズム（Tao-ism）の語が造られ、アンリ・マスペロを筆頭とするフランス学派の学者たちを中心に両者の間に因果関係を認める傾向がある。
