Surveying centuries of Muslim debate on time, Iqbal proposes that divine eternity is 'change without succession' — an organic appreciative duration — while serial clock-time is born only with the act of creation. God is neither frozen outside time nor carried along by it.
Section 5 was the metaphysical pivot of Lecture III: the passage from Ash'arite atomism to Iqbal's spiritual pluralism, from atoms and accidents to egos and degrees of reality. It established that the fundamental unit of reality is not the material atom but the psychic act, that reality is essentially spirit, and that the Ultimate Reality is an Ego from which only egos proceed. That section answered the question of what reality is made of. Section 6 now confronts the question of what reality moves in — the problem of time.
The problem is forced upon Iqbal by the logic of his own argument. If the Ultimate Reality is an Ego — a living, creative consciousness — then that consciousness must have some relationship to time. Does God exist in time, as one being among others carried along by a temporal stream? Does God exist outside time, in a frozen eternity that has no contact with the moving world? Or is there some third possibility that does justice both to God's absolute creativity and to the genuine reality of temporal experience? The way one answers this question determines the entire character of one's theology — and, as Iqbal will show, the entire character of one's civilisation.
The section advances through five major movements. First, Iqbal establishes that Muslim thinkers have always been drawn to the problem of time, partly because the Qur'an foregrounds temporal phenomena (the alternation of day and night) as signs of God, and partly because of the Prophet's identification of God with Dahr (time) in a famous tradition. The Sufi metaphysical tradition, especially Muḥyuddīn Ibn al-ʿArabī, treated Dahr as one of the divine names — giving the problem of time a theological urgency it never possessed in Greek philosophy.
Second, Iqbal surveys the objective approaches to time and finds them all inadequate. The Ash'arites conceived time as a succession of discrete 'nows,' which leads to the absurdity of temporal voids between moments. Newton conceived time as an independent flowing stream, which generates its own paradoxes: the infinite regress of needing another time to measure the first time's flow, and the impossibility of specifying time's beginning, end, or boundaries. Modern physics, however, vindicates the Ash'arite intuition of discontinuity: the universe varies by sudden jumps, and there is, as Rougier reports, 'an atom of time.'
Third, Iqbal diagnoses why the objective approaches fail to reach a complete account: they lack psychological analysis. The Ash'arites arrived at a genuine insight about time's atomic character but could not connect their time-atoms organically to their material atoms, because they never examined the subjective experience of temporality. This is the section's central critical diagnosis.
Fourth, Iqbal surveys later Muslim responses that do incorporate the subjective dimension. Mullā Jalāluddīn Dawānī conceives time as a unified span encompassing all events — a view that anticipates Josiah Royce's Absolute — but then adds the crucial qualification that succession is relative and disappears in the case of God. The Sufi poet Fakhr al-Dīn ʿIrāqī goes further, articulating a hierarchy of temporal experience: the time of gross bodies is divisible into past, present, and future; the time of immaterial beings is serial but compressed; and Divine time is absolutely free from passage, above eternity, without beginning or end. Fakhruddīn Rāzī, the most systematic Muslim theologian to address the problem, subjects all contemporary theories to searching examination but confesses he has reached no definitive conclusions — an admission of intellectual honesty that Iqbal clearly admires.
Fifth and finally, Iqbal offers his own synthesis, drawing on the distinction between the appreciative and efficient selves that he developed in Lecture II. The appreciative self lives in pure duration — change without succession. The efficient self lives in serial, atomic time. And atomic time is born from the movement between the two: from the self's passage from appreciation to efficiency, from intuition to intellect. Applied to the Ultimate Ego, this means that God's time is 'change without succession' — an organic whole that appears atomic only because of the creative movement of the ego. Iqbal identifies this with the position of Mīr Dāmād and Mullā Bāqir: time is born with the act of creation. The section closes with a Qur'anic grounding: 'To God belongs the alternation of day and night.'
The section is pivotal within the lecture's arc. Having established in Section 5 that reality is spirit and that the Ultimate Reality is an Ego, Iqbal must now show that this spiritual interpretation can handle the most fundamental category of experience — time — without collapsing into either the frozen eternity of classical theology or the process-theology of thinkers like Alexander who make God a being in the making. His solution — eternity as non-successional change, serial time as its organic measure — is one of the most original contributions in the entire Reconstruction.
‘Contrary to the ancient adage, natura non facit saltus, it becomes apparent that the universe varies by sudden jumps and not by imperceptible degrees. A physical system is capable of only a finite number of distinct states . . . . Since between two different and immediately consecutive states the world remains motionless, time is suspended, so that time itself is discontinuous: there is an atom of time.’
‘I have not been able to discover anything really true with regard to the nature of time; and the main purpose of my book is to explain what can possibly be said for or against each theory without any spirit of partisanship, which I generally avoid, especially in connexion with the problem of time.’
