Within the depth-psychology corpus, doubt occupies a position of remarkable ambivalence: it is simultaneously a psychological wound, a spiritual peril, and — most provocatively — the very engine of psychic growth. Hollis articulates what may be the tradition’s most affirmative thesis: that doubt is ‘a form of radical faith,’ the necessary corrosive that prevents the ego’s provisional certainties from calcifying into deadening dogma. For Fromm, by contrast, doubt names a constitutive anxiety of modernity — the existential residue of individuation that reason cannot dissolve and that drives Luther’s compulsive faith as surely as it drives contemporary authoritarianism. The Cartesian lineage, prominently present here through the Meditations, treats doubt as a methodological instrument, a disciplined suspension of assent; yet Merleau-Ponty, Ricoeur, and Simondon all interrogate the peculiar self-reflexivity of doubt — the fact that ‘I doubt’ already confirms an existing subject. Brazier positions doubt as one of the five Buddhist dullnesses, a contraction of the deluded self; Moore rehabilitates it as the soul’s creative shadow within faith. Jung’s corpus treats doubt as theologically generative: Satan himself, in the Answer to Job reading, enters as God’s own ‘doubting thought.’ The cumulative tension — between doubt as pathological defense against growth and doubt as indispensable opening — defines the term’s significance across the library.
Doubt is a form of radical faith. The only way we can remain faithful to the mystery of mystery is to preserve ambiguity. Certainty is the enemy of truth.
Hollis argues that doubt, far from being a failure of faith, constitutes its highest form, because genuine fidelity to mystery requires the iconoclastic refusal of fixed categories.

Necessity has been called the mother of invention, but doubt is. Doubt may be threatening in its openness, but doubt nonetheless opens. All great advances in human understanding have come out of doubt.
Hollis positions doubt as the generative force behind all intellectual and psychological advance, reframing it from a swampland affliction into the indispensable aperture of growth.

Doubt is the starting point of modern philosophy; the need to silence it had a most powerful stimulus on the development of modern philosophy and science.
Fromm distinguishes rational from irrational doubt, arguing that the compulsive drive to silence existential doubt — rooted in isolation and negative freedom — underlies both modern thought and authoritarian submission.

What Norman cannot abide is doubt; he must have guarantees. Like a fundamentalist who is so fearful of ambiguity that he or she must insist on a rigid truth.
Hollis reads the inability to tolerate doubt as a character-pathological defense rooted in primal wounding, wherein the provisional self requires certainty to ward off the threat of self-examination.

Yahweh, quite without reason, had let himself be influenced by one of his sons, by a doubting thought, and made unsure of Job’s faithfulness.
Jung locates doubt within the divine itself — Satan as God’s own doubting thought — revealing that even omnipotence is susceptible to the destabilizing force of uncertainty.

Both the angel of belief and the devil of doubt play constructive roles in a full-rounded faith. The third part of the trinity is life in the flesh lived with deep trust.
Moore rehabilitates doubt as the soul’s necessary shadow within faith, arguing that a living spirituality requires the disbeliever as internal counterpart to the believer.

When the basic delusion of self becomes expansive, it appears as pride. When it contracts it manifests as doubt. Thus we have the five dullnesses: greed, hate, delusion, pride and doubt.
Brazier situates doubt within the Buddhist taxonomy of kleshas as a contraction of the deluded self, linking it structurally to greed, hate, and pride as fundamental obscurations.

‘I doubt’: there is no way of silencing all doubt concerning this proposition other than by actually doubting, involving oneself in the experience of doubting, and thus bringing this doubt into existence as the certainty of doubting.
Merleau-Ponty demonstrates that doubt is self-grounding — the act of doubting produces the very certainty it seeks, dissolving the Cartesian abstraction into lived, performative existence.

Between doubting doubt and doubted doubt, a certain relation of distancing is constituted through which, nevertheless, the continuity of the operation is sustained.
Simondon analyzes the reflexive structure of doubt as a process of individuation, wherein the subject both generates and objectivates doubt, constituting memory and selfhood through this internal duality.

The ‘who’ involved in doubt is oblivious to the lack of any sort of other, since, in losing its anchoring, it has left behind the speech conditions of dialogue.
Ricoeur interrogates the Cartesian cogito’s implicit formula ‘I doubt, therefore I am,’ arguing that radical doubt severs the subject from intersubjective dialogue and the conditions of selfhood.

In a great number of languages the word zweifeln [‘to doubt’] is connected with the number zwei [‘two’]. These languages, at any rate, do not deny the existence of doubt.
Abraham traces the etymological and psychological roots of doubt to duality — the irreducible tension between two possibilities — drawing a structural parallel between linguistic form and psychic conflict.

I look upon myself as a child of the age, a child of unbelief and doubt; it is probable, nay, I know for certain, that I shall remain so to my dying day.
Armstrong cites Dostoyevsky to exemplify the modern condition in which doubt is not a temporary obstacle to faith but an abiding existential posture that intensifies rather than diminishes religious longing.

We can doubt everything, especially material things, as long as we have no foundations of knowledge besides those we had previously.
Descartes’ methodological doubt — treating the doubtful as false — is presented here in its fullest systematic form, establishing the epistemological baseline against which depth-psychological reformulations of doubt are implicitly calibrated.

I was deliberately imagining my prior opinions, however probable, to be false: it is not that I actually believed them to be false and asserted their contraries to be true.
Descartes clarifies that his method of doubt is a deliberate heuristic, not a metaphysical assertion of falsehood, distinguishing the performative from the assertoric dimensions of radical doubt.

The denials of doubt will become eventually impossible and, when once the foundation of equality is firmly established… doubt itself will pass away.
Aurobindo treats doubt as a phase-specific obstruction on the yogic path, one that yields not to argument but to the accumulated inner experience of the self’s progressive realization.

We doubt whether others love us because our own love is divided. Wherever we have some reservation or division within ourselves, we look at others through it.
Easwaran interprets interpersonal doubt as a projection of inner division, arguing that the absence of doubt in relationship is correlative with an undivided love in the doubter.

Doubt of this eternal truth tends to lock us into negative patterns. If we can let go of fear, doubt, and distrust, progress will be made.
Within the I Ching interpretive framework, doubt appears as a blockage of chi — an energetic contraction rooted in fear that prevents forward movement and spiritual progress.
