The Kitāb Takrīm al-ma‛īsha bi-taḥrīm al-ḥashīsha and the Kitāb Tatmīm al-Takrīm li-mā fi l-ḥashīsh min al-taḥrīm by Quṭb al-dīn al-Qasṭallānī occupy a prominent place in the Arabic literature scene on drugs in general and on hashish in particular. Its relevance is due to the fact that most of the Arab authors of subsequent centuries made use of these two epistles in drafting their treatises. That is why al-Qasṭallānī is the most frequently quoted authority in the aforementioned treatises. A close (...) look at both epistles reveals a considerable amount of historiographic unknown data to date on Arabic writing devoted to hashish and prompts us to question other generally accepted data. Futhermore, the characterisation of al-Qasṭallānī's historic personality perfectly illustrates the arrangement of orthodox sufi stratum who were the most important defenders of the ideological fight against hashish consumption during the 13th century. At the same time, the study of the contents of their epistles offers us a clear image of the general ideological context in which the controversy among those Sufis who were against and those who were for the ritual consumption for hashish took place.

Qutb al-Din al-Shirazi's life spanned the last two thirds of the seventh/thirteenth centuries. A student of Nasir al-Din al-Tusi, he was involved in the revival of Peripatetic philosophy and science that occurred at Maraghah under his influence. He was significant as a transitional figure, combining Suhrawardi's Illuminative philosophy with the revived Avicennism of his teacher. His commentary on Suhrawardi's Philosophy of Illumination was the main vehicle through which this work was studied by later Iranian philosophers. He was also associated with (...) Ibn Arabi's most important student, Sadr al-Din al-Qunawi. ;Suhrawardi's Philosophy of Illumination contained a new "Science of Light", expressed largely in symbols, intended to provide a reformed basis for physics and metaphysics. Qutb al-Din frequently translated these views into Peripatetic terminology so as to make the relationships between the two systems clearer. Qutb al-Din's Pearly Crown is a popular account of philosophy, incorporating and elaborating much of Suhrawardi's philosophy but omitting or disguising the most controversial and esoteric aspects--especially those related to the World of Image, the Afterlife, and reincarnation. ;Qutb al-Din developed further the notion of the "World of Image." This "fourth world" served both philosophical and religious purposes. His ideas on reincarnation and the cyclical nature of time were especially distinctive and were developed beyond the views found in The Philosophy of Illumination. ;Also included in this dissertation are an annotated bibliography of Qutb al-Din's works and their known manuscripts and an edition and translation of his "Epistle Ascertaining the Reality of the World of Image" {Risalah fi Tahqiq )Alam al-Mithal}.

The central issue in this work is self-knowledge. The human soul is created in the Image of God with a purpose.

Islamic thought, no matter what tradition it belonged to, went through a process in which almost all thinkers after the twelfth century were also commentators of Avicenna (d. 428/1037). When this phenomenon combined with Fakhr al-Dīn al-Rāzī's (d. 606/1210) ability to problematize, his critical readings revealed the aporias and turned them into problems which would occupy the thinker’s mind after him and waiting to be solved. The quiddityof knowledge has an important place among these, both in terms of being closely (...) related to many issues where ontology, epistemology and axiology intersect and being a problem area where the Islamic intellectual traditions’ conception of existence is directly reflected. As seen in the analyses of many thinkers, notably Râzî, the ontology, quiddity and category of knowledge in Avicennian philosophy contain elements that are conducive to encountering important challenges when the system as a whole is taken into consideration. Accordingly, scholars like Shams al-Dīn al-Isfahānî (ö. 749/1349), al-Taftāzānī (ö. 792/1390), al-Sayyid al-Sharīf al-Jurjānī (ö. 816/1413), Alî al-Qūshjī (ö. 879/1474), al-Dawwānī (ö. 908/1502), Sadr al-Dīn al-Dashtakī (ö. 903/1498) have taken the discussion to a further point both in terms of identifying the problem and revealing its implications and proposing solutions. This study aims to analyze the sixteenth-century thinker Kutb al-Dīn al-Ījī’s treatment of this problem who inherited the debates of past on the matter in question. He carries out his evaluations especially through the Alī al-Qūshjī (ö. 879/1474), al-Dawwānī (ö. 908/1502) and al-Dashtakī’s comments on the subject. He makes important contributions by analyzing these scholars’ solution offers con-cerning the problem of categorical status of knowledge and putting forward his own approach. He thinks that Alī al-Qūshjī’s distinction between realization (husūl) and subsistence (qiyām), al-Dashtakī’s theory of transformation and al-Dawwānī’s offer to not put the knowledge under the category of quality are problematic from various aspects.

We argue that there is an incompatibility between the two basic principles of Molinism, i.e., God’s middle knowledge of counterfactuals of creaturely freedom, and divine immutability. To this end, firstly, we set out the difference between strong and weak immutability: according to the latter only God’s essential attributes remain unchanged, while the former affirms that God cannot change in any way. Our next step is to argue that Molinism ascribes strong immutability to God. However, according to Molinism, some counterfactuals of (...) freedom need to be actualized by divine will. We argue that this claim does entail a change in God because it attributes a knowledge to God that involves moving from possibility to actuality through divine will. Therefore, claiming God knows counterfactuals of freedom leads us to reject the strong sense of divine immutability. Further, we argue that assuming God’s knowledge encompasses counterfactuals of freedom cannot be consistent even with weak immutability because, according to Molinism, a change in God’s knowledge requires a change in His essence. We conclude that Molinism is incoherent. (shrink)

Code of conduct in society according to Islam.

This is a major work of Islamic mysticism by the great thirteenth-century Persian poet, Farid al-Din Attar. Translated by A J Arberry, Attar’s work and thought is set in perspective in a substantial introduction.

The appearance of nonlinear equations in science, engineering, economics, and medicine cannot be denied. Solving such equations requires numerical methods having higher-order convergence with cost-effectiveness, for the equations do not have exact solutions. In the pursuit of efficient numerical methods, an attempt is made to devise a modified strategy for approximating the solution of nonlinear models in either scalar or vector versions. Two numerical methods of second-and sixth-order convergence are carefully merged to obtain a hybrid multi-step numerical method with twelfth-order (...) convergence while using seven function evaluations per iteration, resulting in the efficiency index of about 1.4262. The convergence is also ascertained theoretically, and the asymptotic error constant is computed. Furthermore, various numerical methods of varying orders are used to compare the numerical results obtained with the proposed hybrid method in approximate solution, number of iterations, absolute error, absolute functional value, and the machine time measured in seconds. The obtained results outperformed the chosen methods when applied models arising from physical and natural fields were solved. Finally, to observe the convergence graphically, some complex polynomials are plotted as polynomiographs, wherein the rapid convergence of the proposed method is guaranteed. (shrink)
