This study compares Avicenna's and Thomas Aquinas' conceptions of God, theological language, the nature of creative action and the beginning of the universe.

Avicenna's notorious claim that God knows particulars only 'in a universal way' is argued to have its roots in Aristotelian epistemology, and especially in the "Posterior Analytics". According to Avicenna and Aristotle as understood by Avicenna, there is in fact no such thing as 'knowledge' of particulars, at least not as such. Rather, a particular can only be known by subsuming it under a universal. Thus Avicenna turns out to be committed to a much more surprising epistemological thesis: even humans (...) know particulars only in a universal way. (shrink)

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)

Like Plato, Aristotle uses dialectic to interpret and analyze ordinary discourse as well as to ascend to the first principles of philosophy and science. At the same time he says that it is intellect ( noûs ) that apprehends the first principle. With al-Fārābī and Avicenna (Ibn Sīnā), dialectic becomes relegated to dealing with ordinary language. For them demonstration in an ideal language from principles apprehended by the intellect suffices for the philosopher.

The main object of this paper is to clarify and evaluate Avicenna’s view of universals, in light of some modern and contemporarydiscussions. According to Avicenna, universality is a contingent attribute of entities that are in themselves neither universal norparticular. An account of universality as a contingent attribute is offered which clarifies and gives additional support to Avicenna’sview. Nevertheless, it will be argued that Avicenna, through his use of such terms as “nature” and “quiddity,” faces the same problemswhich he attributes to (...) his predecessors. (shrink)

This book addresses the issue of determinism in Avicenna and Averroes through an analysis of their views on chance, matter and divine providence.

In recent years, philosophers have shown a rapidly increasing interest in the problem of consciousness and it is arguably the central issue in current interdisciplinary discussions about the mind. Any convincing theory of consciousness has to account for the perplexing aspects of human self-consciousness. This paper deals with Ibn Sina’s view on the human self-consciousness with special reference to his well-known “Flying Man” thought experiment. In a brief comparative discussion, we will consider some of the parallels between Ibn Sina’s account (...) of “consciousness of consciousness” and the contemporary “higher-order” theories of consciousness. An important point of divergence between Ibn Sina’s line of argument and Descartes’ method over the problem of self-consciousness will be examined, as well. Further, Thomas Nagel’s famous view on the subjective character of conscious experience will be mentioned and compared with the implications of Ibn Sina’s dictum that “our self-consciousness is identical to our existence”.

Few theses characterize more especifically the metaphysics of Aquinas than the thesis of the real distinction between being and essence, the thesis of being as the act of the essence, the thesis of the ontological contingency of the universe and the conception of the cause of the existence of things as subsistent being. The aim of the present work is to prove that these theses, as well as others derived from them, like the claim of the identity of essence and (...) being in God and that of God’s simplicity, result from the previous absolutization of essence, that is, from Aquinas’ essencialist and ontologizing interpretation of the fact that existent individuals are not explicitly mentioned in definitions.

This paper examines and compares the ways in which the Latin Avicenna, that is the Persian thinker’s work as known in Latin translation to medieval Christianthinkers, and Aquinas alter Aristotle’s conception of the breadth and scope of the subject of metaphysics. These two medieval philosophers inherited the problem that Aristotle posed in the Metaphysics concerning the relationship between the study of being as being and the natural study of God. Both thinkers reject the idea that God is the subject of (...) metaphysics and maintain that the one subject of this science is being qua being. They differ, however, in their analysis of the relationship between this subject and God. Avicenna does not directly address this problem, but certain passages from the Liber de prima philosophia seem to suggest, and were interpreted during the middle ages as suggesting, that God falls within the scope of being qua being. Aquinas, on the other hand, analyzes this relationship in detail and firmly denies that God falls within the scope of the subject of metaphysics. (shrink)

Of all the philosophers in the West, perhaps the best known by name and less familiar for the actual content of his ideas is the medieval Muslim philosopher, physician, princely minister and naturalist Abu Ali Ibn Sina, known since the days of the scholastics as Avicenna. In this lucidly written and witty book, L. E. Goodman a philosopher long known for his studies of Arabic thought presents a factual, pithy, and engaging account of Avicenna's philosophy. Setting the thinker in (...) the context of his often turbulent times and tracing the roots and influences of Avicenna's ideas, Goodman offers a factual and credible philosophical portrait of one of the world's greatest metaphysicians. The book details Avicenna's account of being as a synthesis between the seemingly irreconcilable extremes of Aristotelian eternalism and the creationism of monotheistic scripture. It examines Avicenna's distinctive theory of knowledge, his ideas on immortality and individuality, including the famous Floating Man argument, his contributions to logic, and his probing thoughts on rhetoric and poetics. Drawing from the very latest scholarship, Avicenna is more than a philosophical appreciation. L. E. Goodman considers the abiding value of Avicenna's contributions, assaying his thought against the responses of his contemporaries and successors but also against our current philosophical understanding. It will have wide appeal among all Arabists and Islamicists, and among students and scholars of philosophy. (shrink)

The division of the soul and its perceptions are of the most important problems that attracted Ibn Sina`s interest. Ibn Sina held that there are three kinds of the soul: vegeterian, animal, and rational soul, among which only the rational one is immaterial. The main reason of its immateriality is its perception of the inteligibles. Other perceptions are somehow immaterial, that is, perception at the stage of the sense is not abstracted from the mater and its appendixes and at the (...) stage of imagination is abstracted from the mater and not from its appendixes and at the stage of intelligence it is abstracted from both mater and itsappendixes. And so this kind of perception is completely abstracted. Among philosophers who have discussed the problem of mind body distinction, there have been few philosophers who have presented certain proofs for the abstraction of the soul. But this issue was treated in Islamic philosophy. Moslim philosophers have extended the proofs of Plato's Phaedo and the best proof theirs proofs was the simplicity of perception that has been mentioned in Ibn Sina`s works. (shrink)

Thomas of Aquino, from the time he wrote his commentary on the ’Sentences’ through writing the ’Summa of Theology’, recognized how far beyond Aristotle’s was the rational theology of Avicenna. After perfecting his approach to proving the existence of God in the "five ways," Aquinas further developed Avicenna’s organization for treating God’s nature by simplifying Avicenna’s often convoluted thought and added his own developments in content and order. In sum, Aquinas’s treatment of God’s nature depends closely upon Avicenna’s treatment of (...) the subject in his ’Metaphysics’ 8.3-7, even more so than upon Aristotle. This conclusion can be seen by comparing the doctrines of Aristotle, Avicenna and Aquinas on the divine nature. (shrink)

In this article, the author studies some central concepts in Avicenna's and sī's modal logics as presented in Avicenna's Al-Ish r t wa'l Tan īh t ( Pointers and Reminders ) and in sī's commentary. In this work, Avicenna introduces some remarkable distinctions in order to interpret Aristotle's modal syllogistic in the Prior Analytics . The author outlines a new interpretation of absolute sentences as temporally indefinite sentences and argues on the basis of this that Avicenna seems to subscribe to (...) the Principle of Plenitude. He also shows that he has no valid proof of the modal conversion rules and that he uses some rather ad hoc distinctions to show that Aristotle's modal syllogistic is correct. The author also notes some interesting differences between Avicenna's and sī's approaches to modal logic. (shrink)

This article offers a comparative study of three thinkers from almost as many intellectual and cultural traditions: Avicenna, Maimonides, and Gersonides, and discusses the extent of the knowledge of particulars which each one ascribed to God. Avicenna de-reified Aristotle’s abstract and isolated Prime Mover and argued that God can know particulars but limited these to universals. Maimonides disanalogized divine from human knowledge, arguing that the epistemic mode predicated of mankind cannot be equally predicated of God, and that God knows particulars (...) qua particulars even as his Knowing encompasses all of eternity in a single act of knowledge. Attempting an intermediate path between the former’s highly discursive reasoning and the latter’s more scriptural approach, Gersonides postulated that God can know particulars qua particulars—as is befitting a Perfect Being—but this He does ‘mediately’ as it were, via the emanative ordering comprising the separate intelligences and culminating in the Active Intellect.

The paper treats Avicenna’s ’metaphysical’ argument for the existence of God and the modal metaphysics that underpins it. Earlier analyses of modalities attempted to reduce necessity, possibility and impossibility to nonmodal elements, which was done most commonly by appealing to a temporal frequency model of modalities. In contrast, Avicenna believed that modalities were an inherent feature of existence, and so just as there is nothing more basic than existence, so likewise there is nothing more basic in term of which modalities (...) can be explained. The article concludes by considering how Avicenna’s modal metaphysics in turn provides him the means to show the absolute and nonconditional necessity of God, as opposed to the conditional necessity of earlier ’physical’ arguments.

This book is designed to remedy that lack.

The aim of this paper is to clarify Spinoza’s views on some of the most fundamental issues of his metaphysics: the nature of God’s attributes, the nature of existence and eternity, and the relation between essence and existence in God. While there is an extensive literature on each of these topics, it seems that the following question was hardly raised so far: What is, for Spinoza, the relation between God’s existence and the divine attributes? Given Spinoza’s claims that there are (...) intimate connections between God’s essence and his existence – “God’s essence and his existence are one and the same”(E1p20) – and between God’s essence and the attributes – “By attribute I understand what the intellect perceives of substance, as constituting its essence” (E1d4), we would naturally expect that by transitivity, there is a significant relation between God’s existence and the attributes. Yet, as far as I know, there is little, if any, attempt in the existing literature to explicate such a relation, and it is one of my aims of this study to both raise the question and answer it. Eventually, I will argue that for Spinoza God is nothing but existence, and that the divine attributes are just fundamental kinds of existence, or, what is the same, as I will later argue, the intellect’s most fundamental and adequate conceptions of existence. In the first part of the paper I provide some background for Spinoza’s brief discussion in the TTP of God’s name and essence by studying the claims of Maimonides in the Guide of the Perplexed that God’s true essence is necessary existence, and that this essence is denoted by the ineffable Hebrew name of God, the Tetragrammaton (YHVH). In the second part of the paper I point out similar claims Spinoza presents in the TTP, and show how they respond to and echo Maimonides’ discussion in the Guide. In the third part, I examine Spinoza’s apparently conflicting claims in the Ethics about the relationship between God’s essence and existence. In some places Spinoza claims that God’s essence and existence are strictly identical (E1p10: “God’s essence his existence are one and the same”), but in other passages he makes the apparently much more modest claim that God’s essence involves existence (E1d1, E1p7d and E1p11d), which may lead one to believe that there is more to God’s essence than mere existence. I show that Spinoza’s understanding of the relation denoted by the Latin ‘involvit’ is consistent with the strict identification of essence and existence in God, and that Spinoza identifies God’s essence with self-necessitated existence, or eternity. Indeed, Spinoza’s understanding of eternity [aeternitas] as self-necessitated existence (E1d8) is one of the very few Spinozistic concepts that has no trace in Descartes. In this part I will also solve the long-standing problem of the sense in which the infinite modes can be called ‘eternal.’ In the fourth part I turn to the relation between the divine attributes and God’s existence and argue that, for Spinoza, the attributes are self-sufficient and adequate conceptions of existence. Finally, I will attempt to explain what brought Spinoza to deify existence. -/- Part I: “In that Day shall God be One, and his Name One”- Maimonides on God’s Name and Essence. -/- 1.1 Before we delve into the texts, let me suggest a few distinctions between various views on the issue of the relation between essence and existence in God. The view I suspect both Maimonides and Spinoza subscribe to can be termed the divine essence-existence Identity Thesis. -/- Identity Thesis (IT): God’s essence is existence and nothing but existence. We should distinguish the Identity Thesis from the much more common view according to which God’s essence contains existence, or (which I take to be roughly the same) that existence is one of the properties or perfections which constitute God’s essence. The latter view allows for the possibility (though it does not demand) that there is more to God’s essence than bare existence (e.g., God’s essence may include omniscience, omnipotence, etc.). I will term this view the divine essence-existence Containment Thesis. (shrink)

Muhammad al-Shahrastani, the famous Muslim theologian of the 12th century and author of the Book of Religious and Philosophical Sects, was greatly influenced by Ismaili teachings. In this work al-Shahrastani refutes the metaphysics of Ibn Sina (Avicenna) from an Ismaili point of view.

Ibn S¯ına, known to the Latin West as Avicenna, was a medieval Aristotelian— one of the greatest of all medieval Aristotelians. He lived in Persia from 980 to 1037, and wrote mostly in Arabic. Simplicius of Cilicia was a sixth century Neoplatonist; he is known mostly for his commentaries on Aristotle. Both of these men were, broadly speaking, part of the same philosophical tradition: the tradition of Neoplatonic or Neoplatonizing Aristotelianism. There is probably no direct historical connection between them, however, (...) and anyway I will not try to demonstrate one. In this paper I will examine their closely related, but ultimately quite different, accounts of corporeity— of what it is to be a body—and in particular of the essential relationship between corporeity and materiality.

In this paper I shall discuss the relationship between the two known Arabic translations of Aristotle’s Posterior Analytics and Avicenna’s Kitāb al-Burhān. I shall argue that Avicenna relies on both (1) Abū Bishr Mattā’s translation and (2) the anonymous translation used by Averroes in the Long Commentary as well as in the Middle Commentary (and also indirectly preserved by Gerard of Cremona’s Latin translation of Aristotle’s work). Although, generally speaking, the problem is relevant to the history of the transmission of (...) the Posterior Analytics from Greek through Syriac into Arabic, I do not intend to give a systematic presentation of the historical setting in which Aristotle’s work became readily available to the Arabo-Islamic culture. My aim here is rather to isolate and discuss some pieces of evidence concerning the texts that seem to have been available to Avicenna. In addition to that, I shall also provide evidence concerning the relationship with the Greek commentary tradition (in particular Philoponus and Themistius) that is likely to have influenced Avicenna in his discussion of Aristotle’s theory of demonstration and scientific knowledge.

The paper provides some introductory comments and a preliminary translation of Avicenna’s Burhān, IV, 2. I shall first set the stage by outlining the structure of the book (sec. 1). I will then briefly introduce (sec. 2) a number of notions that are dealt with in the first treatise of the Burhān (e.g. definition, description). Burhān, IV, 2 is split into two parts: the first focuses mainly on Aristotle’s An. Post., B, 4, whereas the second covers some of the topics (...) of B, 5 and B, 6. Accordingly, sec. 3 will be devoted to a cursory presentation of Aristotle’s arguments in An. Post., B, 4 along with a more detailed discussion of its Avicennan counterpart, focusing on the indemonstrability of definition; sec. 4, finally, will be a presentation of the second part of the chapter, concerning the relationship between definition and division. An English translation of the entire chapter is appended to the paper and is accompanied by some notes. (shrink)

Abstract. Scholars have long debated the possibility of a mystical or illuminationist strain of thought in Ibn Sīnā 's body of writing. This debate has often focused on the meaning and contents of his partly lost work al-Mashriqiyyūn (The Easterners), also known as al-Ḥikma al-Mashriqiyya (EasternWisdom), mentioned by Ibn Sīnā himself as well as by numerous Western writers including Ibn Rushd and Ibn Ṭufayl. A handful of references to what is called Ibn Sīnā 's “Oriental Philosophy” are also found in (...) the Castilian and Hebrew works of the Castilian Jew Abner of Burgos (ca. 1270-ca.1347), known after his conversion to Christianity as Alfonso of Valladolid. Although the content of these citations has not been identified, it has been proposed that they may preserve otherwise unknown passages from Ibn Sīnā's lost work. This study considers the references to Ibn Sīnā 's so-called “Oriental Philosophy” within Abner's writings and concludes that rather than preserving lost passages from Ibn Sīnā's writing, Abner's references were drawn primarily from Ibn Ṭufayl and offer no support for the argument of a possible mystical or illuminationist strain in Ibn Sīnā 's thinking. -/- Résumé. Depuis longtemps, on a discuté de la possible présence d'une orientation mystique ou “illuminative” dans l'oeuvre d'Ibn Sīnā . Le sens et le contenu de son ouvrage (partiellement perdu) al-Mashriqiyyūn (Les Orientaux), également connu comme al-Ḥikma al-Mashriqiyya (La Sagesse orientale), mentionné par Ibn Sīnā lui-même et par des écrivains occidentaux comme Ibn Rushd et Ibn Ṭufayl, ont souvent été au centre de ce débat. On trouve aussi quelques références à ce qui est appelé la “philosophie orientale” d'Ibn Sīnā dans l'oeuvre du juif castillan Abner de Burgos (ca. 1270-ca. 1347) connu après sa conversion au christianisme sous le nom d'Alphonse de Valladolid. Sans avoir au préalable identifié le contenu de ces citations, on a fait l'hypothèse qu'elles auraient permis de conserver des passages, inconnus par ailleurs, de l'ouvrage perdu d'Ibn Sīnā. Cette étude porte sur les références à la “philosophie orientale” d'Ibn Sīnā dans l'oeuvre d'Abner de Burgos. Elle montre que les références d'Abner semblent avoir été essentiellement tirées d'Ibn Ṭufayl et ne renvoient donc pas aux passages perdus de l'ouvrage d'Ibn Sīnā. En conséquence elles ne peuvent servir d'argument pour confirmer la présence d'une orientation mystique ou “illuminative” dans l'oeuvre d'Ibn Sīnā. (shrink)
