Similar to Meinong, Abū Hāšim al-Ğubbāī held the view that some objects do not exist. This paper is a comparative study between Meinong’s object theory and Abū Hāšim’s theory of nonexistent objects. Our comparative study is mostly done through three topics: the characterization principle, objecthood, and the ontological status of existence. Moreover, Abū Hāšim’s theory of nonexistent objects is based on his theory of states, according to which some things, namely states, which among other things include existence, are neither existent (...) nor nonexistent. In this paper, we have also discussed two arguments on behalf of this claim and then we have examined them from a Meinongian perspective. (shrink)

The aim of this article is to shed light on an understudied aspect of Giordano Bruno's intellectual biography, namely, his career as a mathematical practitioner. Early interpreters, especially, have criticized Bruno's mathematics for being “outdated” or too “concrete”. However, thanks to developments in the study of early modern mathematics and the rediscovery of Bruno's first mathematical writings (four dialogues on Fabrizio's Mordente proportional compass), we are in a position to better understand Bruno's mathematics. In particular, this article aims to reopen (...) the question of whether Bruno anticipated the concept of infinitesimal quantity. It does so by providing an analysis of the dialogues on Mordente's compass and of the historical circumstances under which those dialogues were written. (shrink)

The essence of an accident consists in its relationship to a substance. For we should not imagine that an accident is a thing in its own right to which gets attached a relationship or a link to a substance in which that accident exists. For if so, an accident would be something in its own right, dependent on substance only as extrinsic, and on this view, an accident could be cognized apart from the substance. These outcomes are impossible, however. Hence, (...) what an accident is to something of the substance: either a measure, or a state, and so on. Thus, the Philosopher says that an accident has being only because it belongs to something that has being. (shrink)

This dissertation offers a new and comprehensive analysis of Abū Naṣr al-Fārābī's cosmology by focusing on various important issues that have been largely neglected by the modern scholarship. It provides an examination of the physical, metaphysical, and astronomical aspects of al-Fārābī's cosmology by adopting a multidisciplinary approach that takes into account the history of philosophy and the history of astronomy. Accordingly, my dissertation explores how al-Fārābī attempted to reconcile features of Ptolemaic astronomy with Aristotelian and Neoplatonic theories, an endeavor which (...) resulted in the formulation of innovative cosmological ideas. Chapters I and II provide background information on al-Fārābī's activity as a commentator and his relation to the Greek commentatorial tradition and assess the relevant primary sources. In addition, they examine al-Fārābī's approach to cosmology and his scientific method in terms of both the Ptolemaic astronomical tradition and the Aristotelian corpus. Chapter III addresses problems related to the structure of al-Fārābī's cosmology, especially the origin of his ennadic cosmological model and his spherology. Particular attention is devoted to the question of how Aristotle's unmoved movers and Ptolemy's astronomical theories are reconciled. Chapters IV, V, and VI analyze the place of celestial matter, intellect, and motion respectively in al-Fārābī's cosmology and attempt to redefine the second teacher's relation to the various trends of Greek philosophy. The study stresses al-Fārābī's connection with the Neoplatonic and Peripatetic currents, particularly with thinkers such as Alexander of Aphrod. (shrink)

This article offers a way of approaching the question of causality in Ibn ʿ Arabī’s relational and processual metaphysical system. Ibn ʿ Arabī’s metaphysics is relational in the sense that entities are perceived as the totality of their relationships to God. The Divine Names are theological categories denoting these relations. It is processual in that it perceives the world as the multiplicity of the incessant and ever-changing process of the manifestations of the divine qualities. The world is recreated anew at (...) each moment and entities are societies of divine acts or theophanies. In this framework, causal power is attributed to God and causality describes the regularity and predictability of the related theophanic individualities. The article, then, turns to examine how Ibn ʿArabī presents a participatory account of freedom in accordance with his understanding of causality. The paper, first, briefly summarizes different accounts of causality offered by Muslim theologians and philosophers before Ibn ʿArabī. The second section introduces some relevant aspects of Ibn ʿArabī’s metaphysics for our discussion and rethinks the question of causality within this larger framework. The third section discusses the question of freedom and responsibility of the moral agents. Finally, the paper offers a comparative examination of Ibn ʿArabī’s theory of causality. (shrink)

RésuméDepuis Ibn Mattawayh et Mānkdīm jusqu'à George Hourani et Marie Bernand, les spécialistes ont montré un intérêt constant pour la théorie de la connaissance d' ʿAbd al-Jabbār, intérêt plus grand encore depuis la parution des textes de Muʿtazilites tardifs comme leKitāb al-Muʿtamad fī Uṣūl al-Dīnd'Ibn al-Malāḥimī, et leKitāb Taṣaffuḥ al-Adillade son maître Abū al-Ḥusayn al-Baṣrī. Cet article examine la théorie de la connaissance immédiate d' ʿAbd al-Jabbār à partir de sonMughnī, ainsi que de textes écrits par ses élèves ou par (...) des Muʿtazilites tardifs. Est aussi étudié le rapport entre cette théorie et les arguments théologiques d'ʿAbd al-Jabbār. Ce travail est divisé en deux parties: en premier lieu, j'étudie la définition de la connaissance immédiate par ʿAbd al-Jabbār et les réactions de ses successeurs; en second lieu, j'analyse sa conception des types de connaissance immédiate étroitement liés à ses arguments théologiques. Et à partir de là, je montre comment le désaccord à propos du contenu de cette connaissance est à l'origine du débat opposant les théologiens musulmans (mutakallimūn) à propos de la validité de certains arguments théologiques.
