Within the depth-psychological corpus, fundamentalism is treated not primarily as a sociological or theological phenomenon but as a symptom of a deeper psychic condition — what Thomas Moore, following James Hillman, identifies as the shadow-form that emerges when spirituality loses its soulful ground. The literature converges on a diagnostic reading: fundamentalism arises where interiority has been evacuated, where the polytheistic complexity of soul is reduced to monotonic certainty, and where symbol is replaced by literal prescription. Moore's Hillman-inflected analysis frames fundamentalism as a pathological rigidity that crosses institutional and secular boundaries alike, manifesting wherever an identity or ideology becomes a closed system resistant to ambiguity. Pargament's empirical psychology adds texture, documenting correlations between fundamentalist orientation, prejudice, and diminished 'religious questing,' tracing the mechanism through rigidity at both personal and social levels. McGilchrist situates the phenomenon within a broader cognitive framework — the triumph of the left hemisphere's tendency toward the literal, the explicit, and the decontextualized, wherein form displaces living content. Hillman notes, with characteristic obliquity, that 'traditionalism' as a psychological disposition may carry a genetic component. Hollis catalogues fundamentalism alongside other culturally sanctioned defenses against individuation. Across these voices the critical tension is consistent: between the closed certainty that fundamentalism provides and the open, ambiguity-tolerant engagement that psychological and spiritual maturity demands.
Often, when spirituality loses its soul it takes on the shadow-form of fundamentalism. I am not referring to any particular groups or sects, but to a point of view that can seize any of us
Moore, drawing on Hillman, defines fundamentalism as a universal psychic shadow-form — the pathological rigidity that emerges whenever spirituality is severed from its soulful depth and complexity.

fundamentalism involves a commitment to an inerrant set of teachings about God and humanity, and to an unchanging set of life practices. This commitment leaves little room for personal interpretation or modifications.
Pargament provides an empirical-psychological account of fundamentalism as structural rigidity — personal and social inflexibility that correlates with prejudice and reduced capacity for religious questioning.

no name, no conversation, only this two-word category for explaining her life... In those opening words she told me that she was identified with the story of incest. It sounded like a fundamentalist confession of faith.
Moore illustrates fundamentalism as a secular as well as religious phenomenon — the collapse of a person's identity into a single totalizing narrative that forecloses further individuation.

Truth indeed changes its nature, and becomes simplistic, literal, stateable and knowable, explicit and abstracted from context. The body becomes no longer the best image of the human soul, in Wittgenstein's phrase, but the soul's prison and antagonist.
McGilchrist situates fundamentalism's literalism within a neurological and epistemological framework, identifying it as the triumph of left-hemispheric abstraction over living, contextual meaning.

Codes of conduct lose contact with their primary source in life and become bafflingly recondite... simply to illustrate a trend towards the triumph of form over content.
McGilchrist diagnoses a fundamentalist tendency — the divorce of codified form from living meaning — as a broader cultural and cognitive pathology affecting all traditions.

When spirituality loses contact with soul and these values, it can become rigid, simplistic, moralistic, and authoritarian—qualities that betray a loss of soul.
Moore identifies the psychological markers of fundamentalism — rigidity, moralism, authoritarianism — as diagnostic signs of soul's absence from spiritual life.

Even fundamentalist believers in each of these three religions are generally humane and non-violent. However, fanatical religious zealots, usually drawn from fringe fundamentalist groups of all three religions, have shown themselves capable of utter disregard for human life.
Alexander distinguishes between fundamentalism as a general orientation and its pathological extreme — fanatical zealotry — framing the latter as an adaptation to severe social dislocation rather than a product of religious texts alone.

The religious lexicon provides an unmistakably clear and distinctive set of labels to describe those committed to the tried-and-true (fundamentalists, traditionalists, conservatives, orthodox) and those convinced there is a better way.
Pargament situates fundamentalism within the broader dialectic between conservation and transformation of religious significance, noting the historical tendency of these orientations toward mutual denigration.

genetic 'traditionalism' is not directly associated with actual political (Republican) or religious (fundamentalist, Orthodox) positions. Yet the description of traditionalism does suggest some genetic wiring at the core of conservative, even reactionary, party and church affiliations.
Hillman draws on behavioral genetics research to propose that the temperamental substrate of fundamentalism — 'traditionalism' as rule-following and authority-adherence — may have heritable components.

Hollis's index entry situates fundamentalism as a recurring concept across his discussion of individuation, spiritual authority, and the defenses against genuine self-creation.

Religion for most ceased to be a felt apprehension of the transcendent and became an ideological affiliation, which is
Hollis diagnoses the modern reduction of religion to ideological affiliation — a condition structurally analogous to fundamentalism — as the consequence of myth's severance from lived metaphysical experience.
