Iqbal surveys the available secular remedies for modernity's spiritual crisis and rejects each in turn: medieval mysticism has taught a false renunciation that contents the average man with ignorance; nationalism narrows thought and emotion by mobilising hate and resentment; and atheistic socialism revolts against the very spiritual source that could have given it strength. Only religion in its highest manifestation — neither dogma, nor priesthood, nor ritual — can deliver the 'biological renewal' the modern world needs.
Section 4 presented the second reason for the timeliness of the question 'Is religion possible?' — the existential case: the idea of evolution, received within a naturalistic framework, has produced civilisational despair rather than hope, and even Nietzsche's heroic attempt to sustain a forward-looking vision collapsed into the hopelessness of eternal recurrence. Section 5 now completes the triptych of timeliness arguments with the most devastating diagnosis of all: a survey of the available remedies for modern civilisation's spiritual crisis, and the verdict that every one of them has failed.
The section advances through three movements. First, Iqbal diagnoses the condition of modernity: the modern man has 'ceased to live soulfully, i.e. from within,' absorbed in external facts, cut off from the depths of his own being, paralysed by the systematic materialism that Huxley himself apprehended and deplored. Second, Iqbal evaluates three candidate remedies and rejects each. Medieval mysticism has 'practically failed' — and in the Muslim East has done 'far greater havoc than anywhere else,' teaching 'a false renunciation' that made the average man 'perfectly contented with his ignorance and spiritual thraldom.' Nationalism offers a substitute energy, but it works by narrowing thought and emotion rather than expanding them, drawing on 'the psychological forces of hate, suspicion, and resentment.' Atheistic socialism has a broader outlook but 'rises in revolt against the very source which could have given it strength and purpose.' Third, having eliminated all three, Iqbal declares the crisis and identifies the only remaining resource: religion in its highest manifestation — 'neither dogma, nor priesthood, nor ritual' — which alone can 'ethically prepare the modern man for the burden of the great responsibility which the advancement of modern science necessarily involves.'
This section is the argumentative hinge of the entire lecture. Sections 1–4 established that the question 'Is religion possible?' is both legitimate and timely. Section 5 demonstrates that it is also urgent — because every alternative to religion has been tried and has failed. The lecture's remaining sections (6–11) will then address what form religion must take if it is to succeed where mysticism, nationalism, and socialism have failed.
