Religious fundamentalism continues to be an enormous concern in the aftermath of the 9/11 tragedy since the atrocity involved numerous extremist groups, including religious fundamentalist ones. This horrible tragedy has brought in all citizens of the globe mindful of the existential threat of these organizations. Their existence sparks an immense discourse in various fields, including in the academic field that centres around the query of ‘what drives them to act mercilessly and inhumanely.’ Aside from political matters, their extremism is shaped (...) by their method of approach to the doctrines or dogmas, teachings, ideologies, and religious traditions of faith they espouse. The methodology used by fundamentalists in approaching their religious texts and traditions is one of the major issues confronting religious fundamentalism. That methodology refers to the authoritative method, which entails two notable inquiries. Why do fundamentalists consider their religious doctrines or dogmas to be infallible or unquestionable? Why do they presume that all other knowledge and values are subordinate to their religious texts? This philosophical analysis seeks to investigate and evaluate the flaws of the authoritative method within fundamentalism by contrasting it with the Deweyan experimental or scientific method and bridging the two methods with the ‘reflective method’ the author postulates.
