In Professor Louis Betty’s 2023 interview with Rod Dreher, he summarized the insights of Houellebecq about what happens when religion becomes “religion.”
Once religion becomes definable as religion — that is, once its symbols no longer address themselves to society at large as representative of discipline and moral authority, but rather address only the individual as motivators of religious “moods and motivations” — it is already doomed. Religion must do more than provide a space for the individual to enter, à la [anthropologist Clifford] Geertz, into the ‘religious perspective.’ This is simply not enough for modern people; the symbols therein are too weak, too uncoupled from ordinary existence to give serious motivation. Religion must set a disciplinary canopy over the head of humankind, must order its acts and its moral commitments, must furnish ultimate explanations capable of determining the remainder of social life; otherwise, religion loses itself in the morass of competing perspectives (scientific, commonsense, political, etc.) This is precisely what has happened in the West.
