Iqbal defends the cognitive status of religious experience against the charge that it is merely neurotic or pathological. Conceding for the sake of argument that George Fox may have been a neurotic and Muhammad may have been (as the Orientalists claimed) a 'psychopath,' he insists that the historical effects of their experiences — the transformation of slaves into leaders, the shaping of whole civilisations — cannot be explained as responses to a mere fantasy inside the brain, and demand an objective situation as their cause.
Section 5 completed the triptych of timeliness arguments by demonstrating that every available secular remedy for the crisis of modernity — medieval mysticism, nationalism, atheistic socialism — has failed, leaving religion in its highest manifestation as the only remaining possibility for 'biological renewal.' Section 6 now pivots from diagnosis to defence. Having established that the question 'Is religion possible?' is legitimate, timely, and urgent, Iqbal must now defend the cognitive status of religious experience against the most common modern objection: that such experiences are merely neurotic or pathological phenomena with no epistemic value.
The section advances through three movements. First, Iqbal asserts the factual reality of religious experience: it 'cannot be denied,' the entire religious literature of the world testifies to it, and these experiences possess both 'cognitive value for the recipient' and 'a capacity to centralize the forces of the ego and thereby to endow him with a new personality.' Second, he addresses the neurological-pathological objection head-on with a provocative argumentative strategy: even if George Fox was a neurotic and Muhammad was (as Orientalists claimed) a 'psychopath,' the results of their experiences — the purification of England's religious life, the transformation of 'slaves into leaders of men' — cannot be explained as responses to 'a mere fantasy inside the brain.' The effects demand an adequate cause: an 'objective situation generative of new enthusiasms, new organizations, new starting-points.' Third, Iqbal reframes the 'psychopath' not as a pathological case but as 'an important factor in the economy of humanity's social organization' — one who 'thinks in terms of life and movement with a view to create new patterns of behaviour for mankind' and who is 'not less alert than the scientist in the matter of eliminating the alloy of illusion from his experience.'
The section is strategically crucial because it addresses the objection that any naturalistic critic would immediately raise against the argument of Sections 1–5. If religious experience is merely a neurological artefact — a misfiring of the brain that happens to produce useful social consequences — then the question 'Is religion possible?' is answered not with 'yes' or 'no' but with 'the question is mal-formed: what you call religion is really neurology.' Iqbal's counter is that the reductionist explanation fails on its own terms: it cannot account for the transformative power of the experiences it dismisses.
