Avicenna's Conception of the Efficient Cause

The concept of efficient causation originates with Aristotle, who states that the types of cause include ‘the primary source of the change or rest’. For Medieval Aristotelians, the scope of efficient causality includes creative acts. The Islamic philosopher Avicenna is an important contributor to this conceptual change. In his Metaphysics, Avicenna defines the efficient cause or agent as that which gives being to something distinct from itself. As previous studies of Avicenna's ‘metaphysical’ conception of the efficient cause attest, it takes God as a model agent. This essay considers whether Avicenna's ‘metaphysical’ conception of the efficient cause applies to natural agents. It ultimately argues that Avicenna offers a unified view of the efficient cause, which includes both divine and natural agents. On this view, an efficient cause gives being to another and is simultaneous with its effect. While Avicenna's defence of this view is an important chapter in the history of the concept of the efficient cause, it is also of interest in its own right. By appeal to a version of the principle of sufficient reason, it challenges a widespread view that causes are temporally prior to their effects.     

Forms of gnosis in Sulamī's Sufi exegesis of the Fāti&art1;a

This paper will look at the Sufi interpretations of Sūrat al-fāti&art1;a found in the early mystical Qur'an commentary known as the &art2;aqā'iq al-tafsīr by the well known Sufi, Abū ^c Abd al-Ra&art1;mān al-Sulamī (d. 1021). The Sufi tafsīr of this sūra will be read not only as a compilation of early mystical interpretations of the Qur'an, but also as a unique work by Sulamī himself. A close reading of the various Sufi authors' interpretations set out by Sulamī will show how his own positions concerning the fundamental Sufi concept of ma^crifa come about.     

Tradition,Reason, and Qur’anic Exegesis in the Modern Period: The Hermeneutics of Said Nursi

Key figures in modernist Qur’an exegesis include Sayyid Ahmad Khan (d. 1898) and Muhammad ?Abduh (d. 1905). This article presents the exegetical principles of Bediuzzaman Said Nursi (1877–1960), a Muslim thinker and a major twentieth-century Turkish scholar who is not necessarily to be labelled a ‘modernist’, on tafsīr bi-al-ma?thūr (tradition-based exegesis) and tafsīr bi-al-ra?y (reason-based exegesis) with special reference to the views of early Muslim modernist thinkers. It particularly refers to Nursi’s work on u?ūl al-tafsīr, Mu?ākamāt (Reasonings), and his one-volume commentary, Ishārāt al-i?jāz (Signs of Inimitability), in order to understand his method of tafsīr. The purpose of the article is to place Nursi within the historical framework of Qur’an exegesis and it argues that, while there are some similarities between ?Abduh and Nursi since the latter is influenced by the former, the methodological differences are clear. While ?Abduh’s method is text-based, Nursi’s is based on kalām (Islamic theology). While ?Abduh is critical of the classical style tafsīr and linguistic discussions in tafsīr, Nursi can be considered to be a modern representative of the Ottoman exegetical school and a follower in the way of al-Zamakhsharī (d. 538?1144), Fakhr al-Dīn al-Rāzī (d. 606?1210) and al-Bay?āwī (d. 685/1286).     

Re-reading al-birūnī's India: a case for intercultural understanding

It is argued that until recently the major motive behind the interest in religious traditions other than one's own has been to refute the truth-claims of the former. This attitude was based on the conviction that the religious tradition to which the student of religion belonged contained all that he or she needed to know, since whatever remained outside the authoritative revelation was at best irrelevant and at worst dangerous. Although prevalent throughout history, this approach was not the only model for studying religions other than one's own. There have been scholars within the Islamic tradition who showed genuine interest in studying and understanding other religious traditions on their own terms. Arguably, one of the best representatives of these scholars was al-Birūnī (973–1048 CE) whose accomplishments in other disciplines, notably in natural sciences, overshadowed his crucial contribution to the study of religion. This paper is an attempt to contribute to the current debate in the study of religion by analyzing the method al-Birūnī employed in his treatment of the religious traditions of India. In pursuing the subject, the paper aims to elucidate the phenomenological, dialogical and comparative aspects of al-Birūnī's thought in light of contemporary scholarship.     

Establishing Connections between Aristotle's Natural Deduction and First-Order Logic

This article studies the mathematical properties of two systems that model Aristotle's original syllogistic and the relationship obtaining between them. These systems are Corcoran's natural deduction syllogistic and ?ukasiewicz's axiomatization of the syllogistic. We show that by translating the former into a first-order theory, which we call T _RD, we can establish a precise relationship between the two systems. We prove within the framework of first-order logic a number of logical properties about T _RD that bear upon the same properties of the natural deduction counterpart – that is, Corcoran's system. Moreover, the first-order logic framework that we work with allows us to understand how complicated the semantics of the syllogistic is in providing us with examples of bizarre, unexpected interpretations of the syllogistic rules. Finally, we provide a first attempt at finding the structure of that semantics, reducing the search to the characterization of the class of models of T _RD.     

A Debate About Anderson's Logic

This article is about the history of logic in Australia. Douglas Gasking (1911–1994) undertook to translate the logical terminology of John Anderson (1893–1962) into that of Ludwig Wittgenstein's (1921) Tractatus. At the time Gilbert Ryle (1900–1976), and more recently David Armstrong, recommended the result to students; but it is reasonable to have misgivings about Gasking as a guide to either Anderson or Wittgenstein. The historical interest of the debate Gasking initiated is that it yielded surprisingly little information about Anderson's traditional (syllogistic or Aristotelian) logic and its relation to classical (first-order predicate or Russellian) logic, the ostensible topic; but the materials now exist to interpret Anderson's logic in classical logic, possibly as an algebra of classes. This would be of little interest to contemporary logicians, but it might shed some light on Anderson's philosophy.     

Tūsī on Avicenna’s Logical Connectives ∗

Tūsī, a thirteenth century logician writing in Arabic, uses two logical connectives to build up molecular propositions: ‘if-then’, and ‘either-or’. By referring to a dichotomous Tree, Tūsī shows how to choose the proper disjunction relative to the terms in the disjuncts. He also discusses the disjunctive propositions which follow from a conditional proposition     

The Evolution of Darwin to a “Unique Christian Species” in Modernist-Apologetic Arab-Islamic Thought

Darwin's theory of evolution has been the cause of great distress and the subject of intense and constant debates among Jews, Christians and Muslims. The article analyzes why and how Sunni Muslim-Arab modernist-apologetic scholars, whose approach emphasizes the compatibility of Islam with empirical sciences, shifted from reluctantly reconciling the theory of evolution with the Qur'an in the late nineteenth and early twentieth centuries to rejecting Darwin as a fabricator and describing his theory as a Christian aberration in the late twentieth and early twenty-first centuries. Through a comparative survey that focuses on the works of ?usayn al-Jisr (d. 1909), Mu?ammad Rashīd Ri?ā (d. 1935), Mu?ammad al-Ghazālī (d. 1996), Yūsuf al-Qara?āwī (b. 1926) and Mu?ammad ?Imāra (b. 1931), the article suggests that this shift corresponded with changes in the American anti-evolutionist discourse, and that, while contemporary modernist-apologetic literature casts Darwin as illegitimate, it does not close the door to a future acceptance of the theory of evolution.     

Impossible Antecedents and Their Consequences: Some Thirteenth-Century Arabic Discussions

The principle that a necessarily false proposition implies any proposition, and that a necessarily true proposition is implied by any proposition, was apparently first propounded in twelfth century Latin logic, and came to be widely, though not universally, accepted in the fourteenth century. These principles seem never to have been accepted, or even seriously entertained, by Arabic logicians. In the present study, I explore some thirteenth century Arabic discussions of conditionals with impossible antecedents. The Persian-born scholar Afdal al-Dīn al-Khūnajī (d.1248) suggested the novel idea that two contradictory propositions may follow from the same impossible antecedent, and closely related to this point, he suggested that if an antecedent implies a consequent, then it will do so no matter how it is strengthened. These ideas led him, and those who followed him, to reject what has come to be known as ‘Aristotle's thesis’ that no proposition is implied by its own negation. Even these suggestions were widely resisted. Particularly influential were the counter-arguments of Naīr al-Dīn al-Tūī (d.1274).     

Tracking changes in Jain devotional singing

ABSTRACT

Over the last two and a half decades of research in the ?vetāmbar Mūrtipūjak Jain community in Pune, Maharashtra, I have been in a unique position to track changes in the ways that Jain devotional singing is performed. In order to discuss some observations I have made over these decades, I chose to track some notable consistencies and changes help illuminate the impact of socio-economic conditions on religious practices and musicality of the performances in the region. This chapter will contextualize the performance of one particular stavan, ?rī ?ankhe?var Pār?vanāthnu Stavan, also known as ‘Antarajāmī Su? Alavesara,’ and examine how three performances of this stavan illustrate changes in the ways Jains perform devotional music over the last twenty-five years.     

Polarity and Inseparability: The Foundation of the Apodictic Portion of Aristotle's Modal Logic

Modern logicians have sought to unlock the modal secrets of Aristotle's Syllogistic by assuming a version of essentialism and treating it as a primitive within the semantics. These attempts ultimately distort Aristotle's ontology. None of these approaches make full use of tests found throughout Aristotle's corpus and ancient Greek philosophy. I base a system on Aristotle's tests for things that can never combine (polarity) and things that can never separate (inseparability). The resulting system not only reproduces Aristotle's recorded results for the apodictic syllogistic in the Prior Analytics but it also generates rather than assumes Aristotle's distinctions among ‘necessary’, ‘essential’ and ‘accidental’. By developing a system around tests that are in Aristotle and basic to ancient Greek philosophy, the system is linked to a history of practices, providing a platform for future work on the origins of logic.     

Avicenna on the Primary Propositions

Avicenna introduces the primary propositions (or the primaries, for short) as the most fundamental principles of knowledge. (In this paper, we are not primarily concerned with the primary/first intelligibles as concepts/conceptions.) However, as far as we are aware, Avicenna’s primaries have not yet been independently studied. Nor do Avicenna scholars agree on how to characterize them in the language of contemporary philosophy. It is well-known that the primaries are indemonstrable; nonetheless, it is not clear what the genealogy of the primaries is (§2), how, epistemologically speaking, they can be distinguished from other principles (§3), what their phenomenology is (§4), what the cause of the assent to them is (§5), how to explain the relationship between the ‘innate [nature] of the intellect’ and the primaries (§6) and, finally, back to their indemonstrability, in what sense they are ‘indemonstrable’ (§7). We will try to fill this gap. As a corollary, we will explain why Gutas’s view [Gutas, Dimitri. 2012. ‘The empiricism of Avicenna’, Oriens, 40, 391–436], among others, according to which the primaries are analytic (in the Kantian sense) is not true in general (§8). More particularly, we will argue that some primary propositions can be categorized under Kantian synthetic a priori, consistent with Black’s and Ardeshir’s conjecture [Black, Deborah L. 2013. ‘Certitude, justification, and the principles of knowledge in Avicenna’s epistemology’, in Peter Adamson, Interpreting Avicenna: Critical Essays, New York: Cambridge University Press; Ardeshir, Mohammad. 2008. ‘Ibn Sīnā’s philosophy of mathematics’, in S. Rahman, T. Street, and H. Tahiri, The Unity of Science in the Arabic Tradition, New York: Springer]. We hope that this work opens up some space to study Avicenna’s philosophy of mathematics and logic in connection with his epistemology, philosophy of mind and metaphysics.     

Re-thinking necessity (al-Darūra) in al-Ghazālī's understanding of physical causation

The present article analyzes al-Ghazālī's (1058 – 1111) effort to reconcile the theological concept of a causally efficacious Creator with the idea of regularity, and thus, predictability, in physical nature. Al-Ghazālī reframed the necessity (al-darūra) of causal relationships in nature in order to achieve two goals: one, theological and the other, epistemological. His intellectual solution ultimately preserved both the human ability to know material causal relations as well as divine creative omnipotence, in particular, God's ability to perform miracles. The Muslim discussion thus indirectly contributed to Western speculative thinking on this problem. The balanced approach that al-Ghazālī took, nevertheless, fell by the wayside within the Islamic environment where it was either ignored, or only partially understood, or narrowly and imperfectly interpreted. In the purely Muslim context, it also is essential to underscore the importance of al-Ghazālī's epistemological discoveries in laying the groundwork for the establishment of a paradigm of natural scientific speculation in the medieval Islamic world.     

Al‐Ghazāli's evaluation of abu yazid al‐bistāmi and his disapproval of the mystical concepts of union and fusion

Abū Yazid al‐Bistāmi (d. 874 AD) was a renowned early sūfi who exerted a tremendous influence upon the doctrinal formulation of the sufism of medieval times. A highly controversial figure, he is venerated by some as a top‐ranking saint and sūfi, condemned by others as a notorious heretic, and there are still others who suspend judgement on him. More than 200 years after him al‐Ghazāli (1058‐1111 AD) flourished as the greatest sūfi of all times; he examined and evaluated the teachings of his sūfi predecessors including Abū Yazid. To determine his evaluation of Abū Yazid and his opinion on the related, well‐known concept of man's union with God at the highest peak of spirituality is the main aim of this paper. To achieve this aim al‐Ghazāli's citations from Abū Yazid's teachings on many basic doctrines of sufism, together with his explicit comments on them, are analysed in the second section of the paper, and he is found to have evaluated these teachings as of a very high grade and to have extolled Abū Yazid as a sūfi of the highest rank. The third section studies al‐Ghazāli's opinion on the most important aspect of Abū Yazid's teachings, i.e. his shatahāt or ecstatic utterances apparently expressive of union, fusion and divine indwelling. This began with a consideration of al‐Ghazāli's definition of two kinds of shath and his condemnation of them on the grounds of their harmful consequences. In connection with a study of his condemnation of the shatahāt of Abū Yazid and al‐Hallāj an investigation is made into his opinion on union and fusion. It is found that throughout his sūfi life he condemned them as false concepts. However Abū Yazid's shatahāt, which apparently mean union, fusion, etc. are interpreted in an orthodox manner, and he is adjudged an elect of the elect, a gnostic who reached the level of reality of realities, a perfect sūfi who attained to God. All the above findings are based on al‐Ghazāli's explicit comments on Abū Yazid. The fourth section of the paper deals with his implicit, indirect comments which also prove his appreciation of, and indebtedness to, Abū Yazid in respect of several central concepts of sufism.     

Varieties of Demonstration in Alfarabi

This paper analyzes a classification of different types of demonstration introduced by Alfarabi (d. 950 CE) in his Kitāb al-Burhān (Book of Demonstration). Alfarabi identifies eight combinations of demonstrative syllogisms, grouped in function of the different types of per se relations expressed by their premises and conclusions, where terms are definitionally connected with one another. The list contains a total of thirty-nine moods illustrated by a rich array of examples drawn from various scientific disciplines, including arithmetic, geometry, and natural philosophy. The combinations and moods are discussed extensively by Averroes (d. 1198 CE) in the section of his Epitome of the Organon devoted to the Posterior Analytics and in his Quaesita on logic. Alfarabi’s classification also possibly inspired a simplified taxonomical effort in Avicenna’s (d. 1037 CE) Kitāb al-Burhān.     

The Arabico-Islamic background of Al-Fārābī's logic

This paper examines al-Fārābī's logical thought within its Arabico-Islamic historical background and attempts to conceptualize what this background contributes to his logic. After a brief exposition of al-Fārābī's main problems and goals, I shall attempt to reformulate the formal structure of Arabic linguistics (AL) in terms of the ontological and formal characteristics that Arabic logic is built upon. Having discussed the competence of al-Fārābī in the history of AL, I will further propose three interrelated theses about al-Fārābī's logic, in terms of which I will attempt to redefine it: the logico-linguistic conception, the project of logicization, and nuclear logic. The final question that will arise is how Aristotle's logic could be built upon AL, which has a nature contrary to logic. The present paper also contributes to examining our traditional research habits in Arabic studies.     

Blood in the Mainstream: Kālī Pūjā and Tantric Orthodoxy in Early Modern Bengal

A consideration of how Kālī Pūjā enters festival contexts in early modern Bengal can suggest new ways of thinking about blood sacrifice in Hinduism. In this case, it appears that we may have underappreciated the impact of sectarian conflict. Through an exploration of the traditional origins of public Kālī Pūjā, I argue that its promotion with the attendant sacrifice by Brāhma?a aristocrats such as Rāja K???acandra Rāya of Nadīyā (1710–1782) can be read as a claim on public space for the Tantric yet socially and theologically conservative Smārta Hinduism favored by the upper castes over and against the comparatively egalitarian, sacrifice-averse ethos of the local Gau?īya Vai??ava movement.

     

Aristotle's Syllogistic and Core Logic

I use the Corcoran–Smiley interpretation of Aristotle's syllogistic as my starting point for an examination of the syllogistic from the vantage point of modern proof theory. I aim to show that fresh logical insights are afforded by a proof-theoretically more systematic account of all four figures. First I regiment the syllogisms in the Gentzen–Prawitz system of natural deduction, using the universal and existential quantifiers of standard first-order logic, and the usual formalizations of Aristotle's sentence-forms. I explain how the syllogistic is a fragment of my (constructive and relevant) system of Core Logic. Then I introduce my main innovation: the use of binary quantifiers, governed by introduction and elimination rules. The syllogisms in all four figures are re-proved in the binary system, and are thereby revealed as all on a par with each other. I conclude with some comments and results about grammatical generativity, ecthesis, perfect validity, skeletal validity and Aristotle's chain principle.
