Criticism of the concept of "religion"

The Canadian scholar of comparative religion Wilfred Cantwell Smith argued that religion, rather than being a universally valid category as is generally supposed, is a peculiarly European concept of comparatively recent origin. His work has been enlarged upon by E.J. Sharpe, C.F. Keyes, and Timothy Fitzgerald. Fitzgerald especially notes in The Ideology of Religious Studies that the concept of religion as a study irreducible to sociology, history, etc., is a fallacy caused by a desire to protect the transcendent ideals of world cultures. He claims that writers cannot define a single concept called "religion" that applies to all cultures, because all definitions of religion have the dual effect of setting up an imaginary ideal onto which real practices are merely mapped, and serializing individual identity to include a separate aspect called "religion." In short, "there is no coherent non-theological theoretical basis for the study of religion as a separate academic discipline. The implication of Smith's and Fitzgerald's work is that religion, rather than being a special category which can be criticized or praised as a group, is merely one type of ideology, alongside humanism, Marxism, nationalism and so forth.
