The psychological writings of the Islamic philosopher Avicenna are noted for the hypothetical example he gives of the man suspended in space—the “Flying Man.” This example, which left its impress on the Latin scholastics and has engaged the attention of modern scholars, occurs thrice in his writings in contexts that are closely related, but not identical. Its third occurrence, which represents a condensed version, conveys the general idea. It states, in effect, that if you imagine your “entity,” “person,” “self” to (...) be created at birth fully mature, sound in mind and body, but suspended in temperate air in such a manner that this “self” is totally unaware of its body and physical circumstances, “you will find that it will be unaware of everything except the ‘fixedness’ of its individual existence.”.

In lieu of an abstract, here is a brief excerpt of the content:Ghazali and Demonstrative Science MICHAEL E. MARMURA I MEDIEVALISLA_MICtheologians subjected Aristotle's theory of the essential efficient cause to severe criticism and rejected it. This criticism and rejection finds its most forceful expression in the writings of Ghazali (al-Ghaz~li) (d. 1111).1 In his Tahafut al-Falasifa (The Incoherence of the Philosophers), he argues on logical and empirical grounds that the alleged necessary connection between what is habitually regarded as the natural (...) efficient cause and its effect cannot be proven. He does not, however, take an agnostic stand on this question but proceeds to affirm two points: (1) that there is no causal agency in natural things; (2) that all natural events are the direct creation of God. Ghazali, moreover, does not confine such divine action to the realm of the inanimate and the irrational, in his al-Iqtis.~d fi-l-Ftiqad (The Golden Mean of Belief), he affirms the doctrine that the individual human act, like any other occurrence in the world, is also the direct creation of God. Causal efficacy resides in God alone. But the divine act, for Ghazali, is not an essential act. It does not proceed as the necessary consequence of divine essence. It is the arbitrary decree of the divine will, an attribute coeternal, but not identical with divine essence. Ghazali thus denies essential action altogether. In all this, he gives expression to the occasionalism of the Islamic school of dogmatic theology (kal~m) to which he belonged, the Ashcarite school. Ghazali had also a keen interest in logic. He wrote logical treatises for his fellow theologians, encouraging them to master this art as a tool to rebutt their doctrinal opponents. The~ treatises, in the main, sum up and explain the logic used by the Islamic philosophers--a logic that reflects the Stoic and Aristotelian traditions. Ghazali recognizes formal logic to be philosophically neutral, and hence in no way conflicting with his theology." He does not confine himself to formal logic in these expositions, however, but discusses Aristotelian demonstration. And it is in his statements on demonstration that we seem to be confronted with paradox. Demonstrative science, as understood by the Islamic philosophers, rests on the theory of essential causes and functions in terms of it. Indeed, in his reply to Ghazali's rejection of essential efficient causes in nature, Averroes (Ibn Rushd) (d. 1198) argues Texts frequently referred to in the notes will be abbreviated as follows: Demonstration: Ibn Sin~, Al-Shifa~; Logic V.; Demonstration, ed.

We would have no true knowledge; at best, only opinion. 3For this staunch defender of Aristotle, the theory of natural efficient causality constitutes a necessary condition for demonstrative science. Yet Ghazali in his writings does not deny the claim that demonstration gives us certain knowledge about the natural order. On the contrary, he seems to be affirming this in both his Tahdfutand the logical treatise he appended to this work, Mi~jdral-CIlm(The Standardfor Knowledge).If Ghazali does in fact uphold this claim for demonstration, then he must either deny that the theory of essential efficient causality is a necessary condition for demonstrative science, or fall into contradiction. At first glance, Ghazali's position in the Micy~r,where he gives his most comprehensive treatment of demonstration, is highly ambiguous and suggests contradiction. He seems for the most part to be reproducing the essentials of the Aristotelian demonstrative theory. Although in one section he reaffirms his rejection of necessary causal connection in nature, he nonetheless continues to use such terms as "cause," "effect," "necessity" and "certainty" in what appear to be...

Avicenna, the most influential of Islamic philosophers, produced _The Healing_ as his magnum opus on his religious and political philosophy. Now translated by Michael Marmura, _The Metaphysics_ is the climactic conclusion to this towering work. Through Marmura’s skill as a translator and his extensive annotations, Avicenna’s touchstone of Islamic philosophy is more accessible than ever before. In _The Metaphysics_, Avicenna examines the idea of existence, and his investigation into the cause of all things leads him to a meditation on the (...) nature of God. From this discussion, Avicenna develops a theory of divine causation that synthesizes Neoplatonic, Aristotelian, and Islamic ideas. Within this emanative scheme, Avicenna establishes some of the basic ideas of his religious and political philosophy, as he discusses the divine attributes, divine providence, the hereafter, and the ideal “virtuous” city with its philosopher-prophet as the human link between the terrestrial and heavenly realms. With this edition, _The Metaphysics_ can now be better seen as one of the most masterful works of classical Islamic philosophy. (shrink)

Although Abu Hamid Muhammad al-Ghazali lived a relatively short life, he established himself as one of the most important thinkers in the history of Islam. _The Incoherence of the Philosophers_, written after more than a decade of travel and ascetic contemplation, contends that while such Muslim philosophers as Avicenna boasted of unassailable arguments on matters of theology and metaphysics, they could not deliver on their claims; moreover, many of their assertions represented disguised heresy and unbelief. Despite its attempted refutation by (...) the twelfth-century philosopher Ibn Rushd, al-Ghazali's work remains widely read and influential. (shrink)

The present article is devoted to two issues. The first is the identification of lead and tin in medieval Arabic alchemy. The second is the investigation of whether Arabic alchemists differentiate between these problematic substances or not. These two issues are investigated in the light of a comparison which is made between the facts that are stated about the two problematic substances in the original Arabic alchemical works and those stated in modern chemical literature. It is proved that Arabic alchemists (...) made a sharp distinction between lead and tin. Also, it becomes clear that these two metals were used in a satisfactory purity in the era of medieval Arabic alchemy. As a consequence of the present study, some conclusions are drawn about the existence of some categories of ‘derivatives’ of fusible bodies in Arabic alchemy which are degenerate to modern categories of oxides, carbonates, etc. (shrink)

Some of the foremost living scholars in Islamic thought have come together to create a standard and definitive work on the subject of Islamic thought. Noted scholars from North America, Europe, and the Middle East offer new and generative interpretations of major themes in the field. They address perennial theological and philosophical questions: the nature of the God-head, the ultimate constitution of matter, the world's origin, causality, divine providence and the existence of evil, freedom and determinism, political wisdom, and the (...) reaches of human knowledge, The contributions include historical and analytical expositions of these issues in medieval Islam as well as discussions of individual thinkers, translations of Arabic texts with commentary, comparisons of Greek and Islamic thought, and bibliographical and textual sources. As a whole, these essays offer a wealth of philosophical, theological, bibliographical, philological, and historical information. Among the outstanding contributions are: an article by Charles Butterworth on Aristotle's rhetoric and how it was understood by al-Farabi, Avicenna and Averroes; Richard M. Frank's essay on the concepts of atoms and bodies, one of the most complex subjects in Islamic theology; and an article by Shams Inati on Ibn Sina and single expressions that discusses how language relates to mental processes and the unknown. Michael E. Marmura develops a new perspective on the subject of efficient causality, emphasizing the paradigmatic position of God's relationship to the world; Muhsin Mahdi analyzes a treatise of Averroes' that deals with the relationship between philosophy and law.

At the basis of Ghazali's criticisms of Ash'arite kalam is the thesis that its primary function is the defence of traditional Islamic belief, the 'aqida, against the distortions of heretical innovations (al-bida'). Kalam is not an end in itself and it is error to think that the mere engagement in it constitutes the experientially religious. In the I[hdotu]ya' he maintains in effect that when it is pursued as an end in itself, its dogmas can constitute a veil preventive of the (...) attainment of gnosis (ma'rifa). On the other hand, Ash'arite kalam when not pursued as an end in itself can be an aid in the quest after gnosis. This is implicit in his reference (in Kitab al-Arba'in) to his own major work of Ash'arite kalam, the Iqti[sdotu]ad fi al-i'tiqad, where he states that “it goes deeper in ascertaining [the truth] and is closer to knocking at the doors of gnosis than the official discourse encountered in the books of the mutakallimin.” The I[hdotu]ya' abounds with homilies, guides for the pious, particularly for those seeking mystical knowledge. Ash'arism pervades such homilies. Thus in Kitab al-Tawba, Ghazali formulates, analyzes and defends the concept of human choice in Ash'arite terms. He thus argues that each of the ingredients of this concept - knowledge, power, the decisive will, as well as the ensuing choice - is individually the direct creation of God. Not that the argument for this concept yields experiential knowledge of its meaning within the cosmic scheme of things. For Ghazali such knowledge is only attained through mystical vision. But the Ash'arite argument, when not pursued as an end in itself, can be an aid to the seekers of gnosis. It can bring them closer to knocking at its doors. (shrink)

The theological foundations of Ghazali's causal theory are fully expressed in the chapter on the attribute of divine power in his al-Iqtiād fi al-I'tiqād. The basic doctrine which he proclaims and argues for is that divine power, an attribute additional to the divine essence, is one and pervasive. It does not consist of a multiplicity of powers that produce a multiplicity of effects, but is a unitary direct cause of each and every created existent. In a defense of the doctrine (...) of kasb, Ghazali argues that power in all animate creatures is created directly by God and that there is created with it the object of power, normally, but erroneously regarded as its effect: the object of power is in fact directly created by God. It exists with the created power, but not by it. In his critique of the Mu'tazilite theory of the generated act he again denies that created power has any causal efficacy and denies that inanimate things have any causal efficacy. What one normally regards as the effects of inanimate causes are in reality their concomitants, directly caused by divine power. The discussion of kasb, the longest in the chapter, includes Ghazali's spirited defense of it against possible objections. The defense, however, as will be shown, is not immune against criticism. At the same time, the discussion of kasb, central as it is, has to be understood in the context of the chapter as a whole, whose intricate arguments remain integrated and unified. Hence a brief exposition of the chapter's arguments will first be given, followed by a critical comment on some aspects of Ghazali's defense of kasb. This is then followed by an annotated translation of the entire chapter, a chapter so very basic for the study of Ghazali's position on causality. (shrink)
