Iqbal names what the whole lecture has been building toward: pure duration cannot exist without a self that endures, and the Ultimate Reality is therefore an all-embracing concrete Ego. Nature is the 'habit of Allah,' the study of nature is a form of worship, and McTaggart's famous proof against time dissolves once the future is recovered as open possibility rather than a pre-formed line.
This is the section in which the entire metaphysical architecture of Lecture II reaches its apex — and in which Iqbal finally names what has been implicit throughout: the Ultimate Ego, the Absolute Self whose creative duration is the ground of all reality. Having established that time is real (Section 4), that mechanism cannot account for life (Section 5), that pure duration is an organic whole (Section 6), that taqdīr is creative self-unfolding (Section 7), and that reality is through and through teleological (Section 8), Iqbal now draws the consequence that binds all of these together. Pure duration cannot exist without a self that endures. To exist in time is to be a self. To be a self is to be able to say 'I am.' And the degree of one's 'I-amness' determines one's place in the scale of being.
The section advances through two major movements. The first is constructive: Iqbal argues that Bergson's error was to treat pure time as prior to selfhood, when in fact time is only intelligible as the experience of a self. This leads to the concept of the Ultimate Self — an all-embracing concrete Ego whose 'I-amness' is independent, elemental, and absolute, unlike our finite selfhood which arises from the distinction between self and not-self. Nature, in this account, is not an external material world but the character of the Divine Self — 'the habit of Allah,' as the Qur'an puts it — and the study of nature becomes, quite literally, a form of worship: the pursuit of intimacy with the Absolute Ego through observation of its behaviour.
The second movement is defensive. Having staked everything on the reality of time, Iqbal must confront the most formidable philosophical argument against it: J.M.E. McTaggart's famous proof that time is unreal, published in The Nature of Existence (1927). McTaggart argued that every event must be past, present, and future — characteristics that are mutually incompatible — and that this contradiction proves time to be illusory. Iqbal's response, drawing on C.D. Broad, is that the argument rests on treating the future as if it already exists in a fully shaped form waiting to happen. It does not. The future exists only as open possibility. McTaggart's paradox dissolves once we abandon the picture of time as a static line of pre-formed events and recover the experience of time as living, creative duration.
The section closes with a characteristic Iqbalian move: intellectual humility held together with metaphysical conviction. He confesses that 'it is not easy to solve the mystery of time,' quotes Augustine's famous admission of bafflement, and yet insists that real time is not serial time but pure duration — 'change without succession' — which McTaggart's argument does not touch. Serial time, the time of clocks and calendars, is pure duration 'pulverized by thought.' The Qur'an, in its references to the alternation of night and day, points not to the mechanism of the clock but to the creative activity of God expressing itself in temporal change.
For the Tadreej project, this section establishes two things of foundational importance. First, it makes Khudi — sovereign selfhood, the capacity to say 'I am' — the central ontological category: not a poetic metaphor or a motivational slogan but the criterion by which reality itself is measured. Second, it sacralises the scientific enterprise: the study of nature is not a secular activity that theology must tolerate or accommodate but an intrinsic mode of intimacy with the Divine. These two claims — the metaphysical centrality of selfhood and the spiritual dignity of natural science — are the twin pillars on which Iqbal's entire programme of reconstruction rests.
