674)Dr Nader El-Bizri Of The Institute Of Ismaili Studies Summarizes 'Concepts Of Time' Among Philosophers Spanning The Sweep Of History; Blogpost 400

"The creation according to Islam is not a unique act in a given time but a perpetual and constant event; and God supports and sustains all existence at every moment by His will and His thought. Outside His will, outside His thought, all is nothing, even the things which seem to us absolutely self-evident such as space and time. Allah alone wishes: the Universe exists; and all manifestations are as a witness of the Divine Will"(Memoirs of Aga Khan III, 1954)

"In Islamic belief, knowledge is two-fold. There is that revealed through the Holy Prophet (s.a.s.) and that which man discovers by virtue of his own intellect. Nor do these two involve any contradiction, provided man remembers that his own mind is itself the creation of God. Without this humility, no balance is possible. With it, there are no barriers. Indeed, one strength of Islam has always lain in its belief that creation is not static but continuous, that through scientific and other endeavours, God has opened and continues to open new windows for us to see the marvels of His creation"(Aga Khan IV, Aga Khan University, 16 March 1983, Karachi, Pakistan)

"In sum the process of creation can be said to take place at several levels. Ibda represents the initial level - one transcends history, the other creates it. The spiritual and material realms are not dichotomous, since in the Ismaili formulation, matter and spirit are united under a higher genus and each realm possesses its own hierarchy. Though they require linguistic and rational categories for definition, they represent elements of a whole, and a true understanding of God must also take account of His creation. Such a synthesis is crucial to how the human intellect eventually relates to creation and how it ultimately becomes the instrument for penetrating through history the mystery of the unknowable God implied in the formulation of tawhid."(Azim Nanji, Director, Institute of Ismaili Studies, London, U.K., 1998)

"Thus there was an absolute need for the Divine Word's revelation, to Mohammed himself, a man like the others, of God's person and of his relations to the Universe which he had created. Once man has thus comprehended the essence of existence, there remains for him the duty, since he knows the absolute value of his own soul, of making for himself a direct path which will constantly lead his individual soul to and bind it with the universal Soul of which the Universe is, as much of it as we perceive with our limited visions, one of the infinite manifestations. Thus Islam's basic principle can only be defined as mono-realism and not as monotheism. Consider, for example, the opening declaration of every Islamic prayer: "Allah-o-Akbar". What does that mean? There can be no doubt that the second word of the declaration likens the character of Allah to a matrix which contains all and gives existence to the infinite, to space, to time, to the Universe, to all active and passive forces imaginable, to life and to the soul. Imam Hassan has explained the Islamic doctrine of God and the Universe by analogy with the sun and its reflection in the pool of a fountain; there is certainly a reflection or image of the sun, but with what poverty and with what little reality; how small and pale is the likeness between this impalpable image and the immense, blazing, white-hot glory of the celestial sphere itself. Allah is the sun; and the Universe, as we know it in all its magnitude, and time, with its power, are nothing more than the reflection of the Absolute in the mirror of the fountain"(Memoirs of Aga Khan III, 1954)

Classical concepts of time confronted philosophers with perplexing paradoxes. Some wondered whether time altogether was nonexistent, whereas others doubted the reality of its divisibility into parts by arguing that the past ceased to be, the future does not yet exist, and the present as a moment/now that is without magnitude (i.e., like a mathematical point is not part of time). In addition, it was unclear whether time progressed smoothly or proceeded by way of discontinuous and divisible leaps.

Although inquiries about the nature of time were integrated within physical theories of motion, their broad cosmological and metaphysical bearings had an impact on speculations about creation and causation. In Plato’s Timaeus (37d; 38a) time (kronos) was pictured as a moving image (eikona) that imitated (mimoumenon) eternity (aiona) by circling around according to number (arithmos) and came into existence with the generation of the heavens. In the earliest systemic investigation of the essence and existence of time, which was contained in Aristotle’s Physics (219b3-4; 220a25-b20; 222b20-23), kronos was defined as the number (metron) of a continuous (sunekhes) motion (kinesis) with respect to the anterior (proteron) and the posterior (husteron). Rejecting the claim that time was the movement of the whole (holos), Aristotle argued that the circular, uniform, and continuous motion of the celestial sphere (sphaira) acts as the measure (metron) of time (Physics, 223b21). His theory subsequently received numerous responses by Neoplatonist and Hellenist exegetes; these are grouped in a monumental edition titled Commentaria in Aristotelem Graeca. Damascius argued that time was a simultaneous whole, Plotinus grasped it as the changing life of the soul (Enneads, 3. 7. 11-13), and Simplicius defended the thesis of the eternity of the world against doubts raised by the grammarian Philoponus, who adopted a Christian doctrine of creatio ex nihilo. As for the author of the Confessions, Augustine of Hippo, he noted that tempus (time) was created when the world came to be while affirming that the existential reality of time is grounded in the present (praesens), which in itself is what tends not to be (tendit non esse), given that only eternity was stable (semper stans).

On the basis of a belief in the linear directionality of time, from Genesis to Judgment, Augustine argued that the present of things past was preserved in memory, the presence of present things was confirmed by visual perception, and the presence of things future was secured through expectation. Accordingly, the reality of time depended on an anima who remembers, perceives, and expects events; this is similar to Aristotle’s claim in the Physics (218b29-219a1-6, 223a25) that kronos required psukhe to compute its numbering (arithmein). Ishaq ibn Hunayn’s translation of Aristotle’s Physics (al-Tabi‘a) secured the transmission of the Aristotelian conception of kronos into Arabic, which subsequently inspired variegated philosophical interpretations of time among Muslims. Al-Kindi held that al-zaman (time) had a beginning and an end and that it measured motion according to number (Tempus ergo est numerus numerans motum), whereas al-Farabi and Ikhwan al-Safa’ affirmed that time resulted from the movement of the created celestial sphere (al-falak). Abu Bakr al-Razi claimed that the dahr (perpetuity) was absolute (mutlaq), while taking al-zaman (time) to be a flowing substance (jawhar yajri) that is bound (mahsur) as well as being associated with the motion of al-falak (the celestial sphere). In Kitab al-Hudud, Ibn Sina defined al-zaman (time) as that which resembles the created being (yudahi al-masn) and acts as the measure of motion (miqdar al-haraka) in terms of the anterior and the posterior (mutaqaddim wa muta’akhkhir). He also noted that al-dahr (supra-temporal duration) resembled the Creator (yudahi al-san‘i) insofar that it was stable throughout the entirety of time. In the Isharat wa’l-Tanbihat, he linked time to physical inquiries about motion; in ‘Uyun al-Hikma, he construed it as a quantity (kamiyyat) of motion that measures change (yuqaddir) and whose perpetuity (dahr al-haraka) generated temporality. Time also played a notable role in Kitab al-Manazir (Optics; II. 3, II. 7, III. 7) by the polymath Ibn al-Haytham, who argued that the propagation of light rays was subject to time and consequently inferred that the velocity of light (al-daw’) was finite despite being immense in magnitude. Moreover, he held that acts of visual discernment and comparative measure (al-tamyyiz wa’l-qiyas) were subject to the passage of time even if not felt by the beholder, and he cautioned that if the temporal duration of contemplative or immediate visual perception fell outside of a moderate range, it resulted in optical errors. In addition he listed al-zaman as one of the known entities (ma‘lumat), while taking duration (mudda) to be its essence (mahiyya) and the scale (miqyas) of its magnitude (miqdar) and quantity (kamiyya) that become knowable in reference to the motion of the celestial sphere (al-falak).

Opposing the views of the peripatetic Muslim philosophers, the exponents of kalam (dialectical theology) articulated alternative conceptions of time that rested on physical theories inspired by Greek atomism. Time was grasped by the mutakallimun (dialectical theologians) as being a virtual (mawhum) phenomenon of changing appearances and renewed atomic events (mutajaddidat), whereby a discrete moment (waqt) replaced the concept of a continuous zaman. Motivated by this theory - although resisting its thrust - al-Nazzam believed in the divisibility of particles ad infinitum, which entailed that a spatial distance with infinitely divisible parts requires an infinite time to be crossed unless its traversal proceeded by way of leaps (tafarat); this echoes the Stoic views regarding the Greek notion of halma (leap). When doubting the doctrine of the eternity of the world in Tahafut al-Falasifa, al-Ghazali attempted to show that duration (mudda) and time (zaman) were both created, and he argued that the connection between what is habitually taken to be a cause and an effect was not necessary, given that observation only shows that they were concomitant. Consequently, he proclaimed that the ordering relation of an antecedent cause with a consequent effect does not necessarily rest on an irreversible directionality in time.

In defense of causation, Ibn Rushd argued in Tahafut al-Tahafut that the refutation of the causal principle entailed an outright rejection of reason while asserting that the eternal (al-qadim) was timeless and that the world was subject to the workings of a continuous zaman. Affirming the truth of Genesis, Maimonides asserted in Dalalat al-Ha’irin the belief that time was created, given that the celestial sphere and the motion on which it depended were both generated. Although speculations about time continued with scholars of the calibre of Nasir al-din Tusi, Fakhr al-din al-Razi, Mir Damad, Mulla Sadra, Abu’l-Barakat al-Baghdadi, al-Iji, and al-Jurjani, the elucidation of its uncanny reality remained inconclusive.
