It has long been a truism of the history of philosophy that intentionality is an invention of the medieval period, and within this standard narrative, the central place of Arabic philosophy has always been acknowledged. Yet there are many misconceptions surrounding the theories of intentionality advanced by the two main Arabic thinkers whose works were available to the West, Avicenna and Averroes. In the first part of this paper I offer an overview of the general (...) accounts of intentionality and intentional being found in the linguistic, psychological, and metaphysical writings of Avicenna and Averroes, and I trace the terminology of “intentions” to a neglected passage from Avicenna’s logic. In the second part of the paper I examine the way that Avicenna and Averroes apply their general theories of intentionality to the realm of sense perception. I offer an explanation of why Avicenna might have chosen to denominate the objects of the internal sense faculty of estimation as “intentions”, and I explore the implications of Averroes’s decision to attribute intentionality to the external senses and the media of perception.

Given contemporary interest in Islam, compelled by the astounding violence perpetrated in its name, the author considers what two historians of philosophy, Étienne Gilson and Rémi Brague, writing a generation apart, have to say about medieval Arabic philosophy and the relevance of its study to our own day.

This paper closely examines Strauss’ conception of “Medieval Enlightenment”. It focuses on the central role that Arab philosophy has played in the development of Strauss’s thought and discusses the validity of the uses he makes of it. It also emphasizes the interest of Strauss’s analyses as regards Arab philosophy while drawing attention to the tensions they create. It claims that Strauss’ involvement in the quarrel between Ancients and Moderns aims at showing that medieval philosophy cannot (...) be reduced simply to the effort to reconcile philosophy and religion. The ideas of some Arab philosophers cropped up throughout Strauss’s philosophical development and determined his interpretation of Maimonides and Plato as well as his stance in opposition to the moderns. However Strauss’s idea of the “medieval Enlightenment” remains fundamentally ambiguous. Is that Enlightenment supposed to be an argument for the preservation of faith alongside reason or does it rather express a kind of atheism or disguised materialism? (shrink)

Medieval Arabic algebra is a good example of an artificial language.Yet despite its abstract, formal structure, its utility was restricted to problem solving. Geometry was the branch of mathematics used for expressing theories. While algebra was an art concerned with finding specific unknown numbers, geometry dealtwith generalmagnitudes.Algebra did possess the generosity needed to raise it to a more theoretical level—in the ninth century Abū Kāmil reinterpreted the algebraic unknown “thing” to prove a general result. But mathematicians had no (...) motive to rework their theories in algebraic form. Because it offered no advantage over geometry, algebra remained a practical art in both the Islamic world and in Europe until the scientific uphevals of the 17th–18th centuries. (shrink)

A critically important development in the tradition of philosophy, as understood by Arabic authors, was the inclusion of both rhetoric and poetics within logic. While these writers' conception of the logical Organon gave appropriate place to the theory of demonstration as found and defined in Aristotle's Posterior Analytics, they added to it the syllogism not only of dialectic, but of rhetoric and poetry as well. By attaching the latter two arts to logic, the Arabic philosophers created a (...) contextual claim about rhetoric and poetry which tended both to weaken the status of either one as a mode of nonlogical discourse and yet potentially to enhance their importance as tools of cognitive activity by recognizing in them some form of syllogistic reasoning.

In lieu of an abstract, here is a brief excerpt of the content:Weeds: Cultivating the Imagination in Medieval Arabic Political PhilosophyMichael S. KochinAny reader of Plato’s dialogues in their entirety feels the constant tug of two very different solar motions. In the Laws the young field-legates (agronomoi) of the city move in a twelve-month cycle through each of the divisions of the city’s territory (Laws 760) in obedience to the law and the gods of the city. Socrates, too, (...) moves through the city, questioning each citizen about the beliefs concerning the virtues implanted by the city’s laws and myths. Socrates, like the field-legates, moves in “obedience” to the command of the sun-god Apollo, a command that Socrates claims to have received through the god’s oracle at Delphi.1 To live in the light of the sun of reason is only possible within a city totally ordered in imitation of heavenly order—so speaks the Laws.2 To follow the sun is to move in opposition to the shadows of artificial light that dominate all actual and even possible cities—so speaks the Apology and, more explicitly, the Republic.Our learned prejudices about these two solar motions lead us to divide Plato’s thought into periods of composition. Socratic heliotropy belongs to the dialogues of Plato’s earlier period, especially the earliest, the Apology, scholars believe; the city itself in seasonal motion belongs to the dialogues of Plato’s later period, and especially the latest, his Laws. The Republic, which describes the best city as an artificially lighted cave, whose inhabitants ought nonetheless to be ruled by the philosopher-king who has, at least momentarily, seen the sun, belongs to Plato’s middle period. [End Page 399]Whatever the merits of this family of readings as interpretations of Plato, 3 they use a scholar’s device to avoid coming to terms with a genuine tension. The two modes of solar motion represent two different modes of relating philosophy to politics, even under their modern guises of theory and practice. Either the philosopher is to bring the political into rational order, or he is to bring his own life into rational order against the disorders and deliberate confusions of the political. Either the philosopher is to weed the fields of the city of disorderly weeds, or he himself is a weed or, more politely, a wildflower, pushing up toward the sun through the broken asphalt of politics.Plato himself seems to resolve this tension by distinguishing between the philosopher’s duties in the best city and in other cities. As Socrates says in the Republic:Observe, then, Glaucon, that we won’t be doing injustice to the philosophers who grow up among us, but we will say just things to them, when we compel them to care and guard for the others. For we will say that those who are of their sort who grow up in the other cities fittingly do not share in the labors therein. For they grew in them spontaneously though the regime in each did not intend it, and the spontaneously grown has a just claim not to be eager to repay the cost of its nurture to anybody, since it owes [its] nurture to nobody. But you we reared up, just as in hives, as leaders and kings for yourselves and the rest of the city, and you have been educated better and more perfectly than those and are more able to have a share of both [philosophy and rule]. Each of you must then go down in turn to the common dwelling of the others and accustom yourself to the shadows there. For when you are accustomed, you will see in a myriad ways better than those there, and you will know the images, that they are images and of what they are images, on account of your having seen the true things that concern the beautiful, the just and the good. 4Yet Plato’s Socrates availed himself only partially of the just claim of the philosopher in an actual city that contributed nothing to his nurture. While Socrates took only a minimal part in the official business of the city, he never hesitated to [End... (shrink)

The paper concerns the Commentary on Aristotle's Poetics written by Avicenna (Ibn Sina : 930-1037AD). The paper is divided into two parts, the first of which examines Avicenna's account of poetic imagination and the use he makes of this concept in justifying a 'poetic syllogism' that accounts for aesthetic validity. The second part develops this account of the poetic syllogism to show that the completeness of the syllogistic requires us to consider the kind of commurlty and moral validity sustained by (...) poetic validity. To explain the first claim - for poetic syllogisms - the paper examines Avicenna's writings on logic and parts of his commentaries on the Prior and Posterior Analytics, linking these to issues in his commentary on the Poetics. To explain the relation of poetry to community, the paper develops issues from the commentary on the Poetics, especially Avicenna's use of the concept of 'themes'. (shrink)

In Being Another Way, Dustin Klinger recounts the history of how medieval Arabic philosophers in the Islamic East grappled with the logical role of the copula 'to be,' an ambiguity that has bedeviled Western philosophy from Parmenides to the analytic philosophers of today. Working from within a language that has no copula, a group of increasingly independent Arabic philosophers began to critically investigate the semantic role that Aristotle, for many centuries their philosophical authority, invested in the (...) copula as the basis of his logic. Drawing on extensive manuscript research, Klinger breaks through the thicket of unstudied philosophical works to demonstrate the creativity of postclassical Islamic scholarship as it explored the consequences of its intellectual break with the past. Against the still widespread view that intellectual ferment all but disappeared during the period, Klinger shows how these intellectuals over the centuries developed and refined a sophisticated philosophy of language that speaks to core concerns of contemporary linguistics and philosophy.

The article comments on the epistemological foundations of medieval Arabic science and philosophy, as presented in five earlier communications, and attempts to draw some guidelines for the study of its social history. At the very beginning the notion of "Islam" is discounted as a meaningful explanatory category for historical investigation. A first part then looks at the applied sciences and notes three major characteristics of their epistemological approach: they were functionalist and based on experience and observation. The (...) second part looks at the theoretical sciences and notes that their epistemology was based on geometrical as well as (b) syllogistic modes of proof, and that the particular approach of scientists and philosophers was determined by (c) whether the motivations of each were scientific or non-scientific (e.g., religious, dogmatic, eristic, etc.). A third part concludes that for medieval Arabic-writing scholars with a scientific motivation the epistemological bases of their work were common to scientists to all cultures, and that the causes of advance or decline of Arabic science and philosophy have to be sought in social factors. In this regard three factors are presented as instrumental: (a) the level of patronage and wealth in any given society within the medieval Islamic world, (b) the cultural attitude of ideological laissezfaire in Sunni Islam which neither imposed nor adopted authoritative solutions in scientific and philosophical issues, and (c) the temporal and local specificity of scientific activity that makes the social contextualization of each science necessary in historical work.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 61.4 (2000) 539-560 [Access article in PDF] Plenitude, Possibility, and the Limits of Reason: A Medieval Arabic Debate on the Metaphysics of Nature Taneli Kukkonen In a recent article Simo Knuuttila has examined the argumentative patterns of modern cosmology, especially the search in fundamental physics for an "ultimate explanation," a unified "Theory of Everything" that would subsume all more local theories (...) under its aegis. Knuuttila goes on to compare contemporary modes of explanation with previous ways of conceiving of the metaphysics of understanding. As it turns out, on the cosmological borderline where physics shades into metaphysics desires similar at heart have fueled the efforts of thinkers throughout the history of western thought. When what is at stake is the final intelligibility of the world, shared ideals of necessity, transparency, and simplicity come to the fore. More often than not, theological concerns and preconceptions accompany these notions. 1One can react to this finding in one of two ways, either by retorting that the moderns have not gotten very far or by pointing out that earlier discussions on the topic were often quite philosophically sophisticated. In this article I propose to investigate how some of the issues raised by Knuuttila figure in a specific historical context. This is the debate on the pre-eternity of the world initiated by the celebrated Muslim theologian Abû Hâmid al-Ghazâlî (1058-1111) in his polemic arguing for The Incoherence of the Philosophers (Tahâfut al-falâsifa, 1095) and later picked up by the Andalusian philosopher Averroës (1126-98) in [End Page 539] his reply, The Incoherence of the Incoherence (Tahâfut al-tahâfut, 1180). 2 The exceptionally rich cosmological materials could be taken in any number of directions, but I will focus on three main issues: the discussants' construction of the domain of possibilities (i.e. the relation of the possible to the actual), their understanding of the reasonability of creation, and the question of its finitude and infinity. The study is undertaken partly to illustrate the sophistication with which the topics were handled in medieval Islamic philosophy, but in each case I will also draw parallels with certain modern conceptions, and I submit that in each case al-Ghazâlî's and Averroës's debate throws light on the contemporary discussion. In the final section I will develop this contention further by pointing to a connection between finitude and possibilities which I believe has both heuristic and existential value. Plenitude and Possibility Among historians of philosophy it is now acknowledged that in late medieval discussions certain modal theoretical innovations were instrumental in bringing about profound change in the western worldview. A conceptual shift occurred where, roughly speaking, a single intelligible universe was exchanged for several possible worlds. In Knuuttila's estimation this change in worldviews was in some ways more fundamental than anything modern science has produced since. 3 This claim deserves consideration but I would like first to outline what the change was about, for in al-Ghazâlî's and Averroës's debate this shift in modal paradigms is clearly discernible.Representative of the philosophers' point of view, Averroës holds onto the received Arabic Aristotelian interpretation of setting possibilities in a statistical temporal-frequency framework. According to this account, what is truly possible must at some time be realized--this is a technical interpretation of what has after Lovejoy commonly become known as the principle of plenitude. 4 As a [End Page 540] corollary, what always is is necessarily. The cosmological consequences of these assumptions can be outlined as follows. First, lest God's creative possibilities be limited, it must be admitted that the world could have been created however long ago in the past. By extension God must have been able to create the world an infinite time ago. But if it is a genuine possibility that the world is eternally old, then according to the principle of plenitude, this possibility is an actual fact. Once it is... (shrink)

Collected in this volume are ten essays on Islamic philosophy, some of which have appeared before. The topics range from historical observations on the Islamic-European transmission of ideas to detailed examinations of Arabic developments in logic. The most comprehensive discussion of the latter concerns the theory of temporal modalities as found in Avicenna, al-Qazwini al-Katibi, et al. Of much wider interest is the inquiry into the Arabic concern with the notion of "existence." The author surprises the reader (...) here by pointing out that Al-Farabi was the first to deny that existence is an attribute; that Brentano's notion of "intentional inexistence" was anticipated by both Avicenna and Averroes; that certain teachings of al-Qazwini al-Katibi accord exactly with Russell's work concerning vacuous definite descriptions. The work as a whole provides considerable evidence for Rescher's thesis, fully articulated in the final essay, that "there is no such thing as an Arabic philosophy" but only "Greek philosophy carried forward in an Arabic-language setting." Indicative of this is the correspondence between Avicenna's formulation of the "logic of questions" and the Aristotelian table of categories. Another example is the commentary of Ibn al-Salah on Book II of Aristotle's Posterior Analytics. More familiar is the syncretistic Arabic adaptation of the doctrines of Timaeus and De Caelo; this influence is discussed at length with respect to Al Kindi's cosmology. In summation, this author's work fills a number of gaps in the continuity of logical development from the Ancient-Medieval period to that of the early Renaissance.--W. S. (shrink)

The earliest debate on the argument from ignorance emerged in Islamic rational theology around the fourth/tenth century, approximately seven centuries before John Locke identified it as a distinct type of argument. The most influential defences of the epistemological principle that are encountered in Mu sources, particularly r and al-Malimar, and was eventually classed as a fallacy by Fakhr al-Dzyat al-l contains the most definitive and comprehensive refutation of classical kalm summa.

This paper discusses the thought of the medieval Maghrebin thinker Ibn Khaldun through the prism of the philosophy and sociology of law and politics. I will first try to illustrate how, even if Ibn Khaldun wrote in the fourteenth century, he anticipated many core concepts that are characteristic of modern Western sociological and philosophical thought. The argument is thus made that his thought can, and indeed must, be rescued from the wide neglect that, outside the specialized field of (...) Khaldunian studies, it has so far suffered in our treatment and teaching of the history of politico-legal sociological thought. I will then claim that the scheme he devised to explain the rise and fall of civilizations can also, with due care, be used to frame and understand the political and cultural landscape in which the West and the Islamic world are presently engaged in a difficult dialogue. The discussion is in this sense offered in the hope of making a contribution to the current politico-legal philosophical and sociological debate on multiculturalism, and on the limits of its scope.

RésuméUne innovation latine médiévale relativement bien connue est la doctrine de la supposition distributive. Cette notion est venue à être utilisée dans la théorie syllogistique à la fin du Moyen Âge et au début de la période moderne, alors que les logiciens latins cherchaient à établir des règles générales pour la productivité syllogistique à travers les différentes figures. Il est beaucoup moins connu que certains logiciens de la tradition arabe médiévale ont également tenté d’établir des règles générales pour le syllogisme, (...) faisant appel à ce qu’ils appelaient la « généralité du sujet ». Dans le présent article, j’introduis cette utilisation de la « généralité du sujet » dans certains ouvrages arabes influents en logique du XIIIe au XVIe siècle, en particulier Al-ǧumal par Afḍal al-Dīn al-Ḫūnaǧī (mort en 1248) et Tahḏīb al-manṭiq par Saʿd al-Dīn al-Taftāzānī (morten 1390) et certains de leurs commentateurs.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 40.4 (2002) 541 [Access article in PDF] Book Review Prophecy: The History of an Idea in Medieval Jewish Philosophy Howard Kreisel. Prophecy: The History of an Idea in Medieval Jewish Philosophy. Dordrecht: Kluwer, 2001. Pp. x + 669. Cloth, $200.00. This is a big book on a big subject. Kreisel offers us a full view of the most (...) substantial discussions in the Jewish Middle Ages of the phenomenon of prophecy (the cognitive awareness of the word of God) and of the bearer of the prophetic message. Even more, he does not stop with the end of the medieval period, but proceeds to Spinoza, whose ideas about prophecy and the prophet are shown, however, to depend upon medieval views, even while turning them on their head.Kreisel presents the views of seven thinkers: Saadiah Gaon, Judah Halevi, Maimonides, Gersonides, Crescas, Albo, and Spinoza. The chronological span of those covered is roughly seven hundred years, from the middle of the tenth century to the middle of the seventeenth century. Equally broad are the geographical span, from Baghdad to Andalusia to Amsterdam; and the linguistic diversity, Arabic, Hebrew, and Latin.The challenge to be met in such a large project is to produce a coherent narrative in which the various participants talk to, not past, each other. After all, there is no prima facie reason why seven thinkers, writing at different times, in widely dispersed geographic locations, and in different languages, should all be conjuring up the same general ideas about prophecy. Even allowing for the religious tradition common to them and the biblical (Hebrew) background, there is still potentially much to divide them. The success of the book depends upon weaving together in a perspicuous fashion the disparate discussions.Kreisel is very aware of the challenge and rises to the occasion. He does much more than just present seriatim the views of his chosen thinkers. He presents their respective positions in dialectical fashion, with, for example, Maimonides responding to Halevi, Gersonides to Maimonides, and Spinoza to the entire prophetic tradition. The dialogue between thinkers throughout the medieval centuries on the subject of prophecy moves between poles of naturalism and supernaturalism, from understanding prophecy and the prophet without emphasizing divine intervention to understanding the same in less naturalistic ways. No one before Spinoza dismissed this project of accounting for how mortal (finite) minds could comprehend the divine, and within the medieval period itself Kreisel distinguishes strongly between those (especially Maimonides and Gersonides) who emphasized the human element in prophecy, the intellectual and moral conditions for prophetic insight, and those (especially Halevi and Crescas) who emphasized the role of the divine in prophecy. Given this latter dichotomy, Spinoza and Maimonides, so different in other ways, may be seen as sharing more in common with each other than either share with Halevi and the "supernaturalist" tradition that he represents.Kreisel works hard to present a philosophical dialogue between thinkers. This is important, lest the debate collapse into one between rationalists and religious fundamentalists. Halevi and Crescas emerge as important philosophers in their own right, even as they indicate the shortcomings of Greek wisdom and, in the case of Crescas, of the naturalism and reductionism of Maimonides and Gersonides. The end result of Kreisel's careful reconstruction is a deep discussion of the epistemology and politics of prophecy. The interested historian of ideas will learn much about medieval debates relating to (divine) knowledge of particulars, the nature of miracles, the nature and role of the imagination in prophecy, human happiness and perfection, and the prophetic mission.I would signal for special notice and attention the importance, stressed by Kreisel, of the universalist and cosmopolitan (Enlightenment) implications of the prophetic teachings of thinkers like Maimonides and Spinoza, who (again) diverge from each other in so many ways. Kreisel demarcates the latter thinkers from those like Halevi, whose supernaturalism undergirds a parochial, even racialist, belief in the superiority of the Jews. Finally, by stressing the (human) intellectual and/or moral qualities that are requisite for prophecy, Kreisel makes a... (shrink)

In the present paper, I assume that the notion of “truth” in philosophy would not have been clarified and tackled properly, if philosophers did not take into account earlier Arabic Medieval research contributions and build upon previous research findings. In the first place, I embark on the scrutiny of the rich aspect (or nature) of the Arabic Lexicon in terms of the “truth” meaning. In the second place, I take on the assumption that Arabic linguistic (...) traditions imply different kinds of truths, depending on various spheres of human thoughts and actions based on the logical approach to “truth” (from Al-Kindi up to Averroes via Al-Farabi and Avicenna) and the term “al-haqiqha” as transliterated from Arabic, remain central. In conclusion, I take on an approach to “truth” that gives worth to logical perspectives at the very heart of Medieval Arab traditions in the light of what I would label as the “Omni-cultural Universality of Logic and Science”.

The Ikhwan al-Safa (Brethren of Purity), the anonymous adepts of a tenth-century esoteric fraternity based in Basra and Baghdad, hold an eminent position in the history of science and philosophy in Islam due to the wide reception and assimilation of their monumental encyclopaedia, the Rasa'il Ikhwan al-Safa (Epistles of the Brethren of Purity). This compendium contains fifty-two epistles offering synoptic accounts of the classical sciences and philosophies of the age; divided into four classificatory parts, it treats themes in mathematics, (...) logic, natural philosophy, psychology, metaphysics, and theology, in addition to didactic fables. The Rasa'il constitutes a paradigmatic legacy in the canonization of philosophy and the sciences in mediaeval Islamic civilization, as well as having shown a permeating influence in Western culture. This is the fifth volume in a series presenting the very first critical edition of the Rasa'il in its original Arabic, complete with the first fully annotated English translation. Epistle 52: On Magic is the last in the corpus, and presents the short version of the 'Epistle on Magic, Incantations, and the Evil Eye'. Within its pages the authors of the epistle argue for the legitimacy of magic and the other occult sciences, and seek confirmation of their views in authorities as diverse as Plato, the Qur'ân, the Torah, the astrologer Abû Ma'shâr, and the mysterious sect of pagan star-worshippers known as the Sabians of Harrân. As in all other volumes of the series, this volume provides the first critical edition of the Arabic text, together with an English translation and a substantial range of notes. An extensive introduction highlights the unique relevance of this treatise within the framework of the Brethren's encyclopaedia itself, and to the history of science in general. (shrink)

Philosophy and religion were the two important sources of knowledge for medieval Arab Muslim polymaths. Owing to the difference between the nature of philosophy and religion, the interplay between philosophy and religion often takes the form of conflict in medieval Muslim thought as exemplified by the Al-Ghazali versus Averroes (Ibn Rusd) polemic. Unlike the Al-Ghazali versus Averroes (Ibn Rushd) polemic, the interplay between philosophy and religion in the political philosophy of Abu Nasr Alfarabi (...) takes the form of harmonious co-existence. Although, for Alfarabi, religion is an inferior form of knowledge as compared to philosophy, the present article will show that philosophy and religion play equally significant roles in Alfarabi’s virtuous city and that in the absence of either philosophy or religion, the political system proposed by Alfarabi cannot exist.
