Although Avicenna does not explicitly develop a 'theory of intentionality', one can reconstruct his account of intentionality through an analysis of his thoughts on the relation between mind, meaning, and thing. We take up this task in this paper through an analysis of Avicenna's theory of the considerations of quiddity. First, we clarify Avicenna's idea of 'quiddity', and show how it functions as a core of 'meaning' which remains identical in its different modes of realization. Second, through an examination of the very notion of 'consideration' (i'tibār), we distinguish between two aspects of the mind, i.e. mental act and mental existence. This helps us clarify what Avicenna means by the existence of a quiddity in mind and in what sense, if any, it is essential to intentionality. Third, addressing the problem of the relation between 'mental existence' and 'external existence', we show how the mode of existence of a quiddity, including its concrete existence, is posited in and through intentionality. This implies that both being and quiddity are moments of the intentional object, and thus, intentionality, for Avicenna, is a dyadic relation between the intentional act and the intentional object. We conclude by reconstructing the structure of intentionality in Avicenna. [ABSTRACT FROM AUTHOR]

The standard interpretation of Avicenna's correspondence theory of truth posits that propositions either correspond to what exists extramentally or otherwise their truthmaker is mental existence. An influential post-Avicennian philosopher, Naṣīr al-Dīn Ṭūsī (d. 1274) points to the insufficiency of the above division of propositions and their respective truthmakers. He mentions the possibility of conceiving false propositions, such as ‘One is not half of two’ and postulates the necessity of the existence of another truthmaking domain for their true counterparts which he calls nafs al-amr. It is where objective and timeless entities, such as mathematical propositions, are located. While some claim that Ṭūsī's identification of this domain with the first Separate Intellect is a testimony to his Avicennian convictions, Ṭūsī's solution is a conspicuous departure from Avicenna that not only helps him remedy the insufficiency of Avicenna's theory of truth but is consistent with his critique of Avicenna's theory of God’s knowledge.

Avicenna's discussion of future contingent propositions is sometimes considered to entail metaphysical indeterminism. In this paper, I argue that his logical analysis of future contingent statements is best understood in terms of the epistemic modality of those statements, which has no consequences for modal metaphysics. This interpretation is corroborated by hitherto neglected material concerning the question of God's knowledge of particulars. In the Taʿlīqāt, Avicenna argues that God knows particulars by knowing their complete causes, and when contrasted with the human knowledge of particulars, this epistemically superior access shows that the contingency of statements about future particulars is not due to the modal properties of real particulars but to the nature of human access to them.

In classical Arabic philosophy, the topic of consciousness is commonly associated with Avicenna's 'Flying Man' thought experiment. But Avicenna's explorations of the nature of consciousness are not confined to the Flying Man, and he is by no means the only classical Islamic thinker to deem consciousness an important feature of our experience. Consciousness also plays a important role in the epistemology and moral psychology of Avicenna's intellectual rivals, the theologians (mutakallumūn), who represent important sources for Avicenna's own theorizing about consciousness. And while Avicenna's philosophical successor and critic, Averroes, seems to banish consciousness from the core of his cognitive psychology, in doing so he seems to anticipate contemporary efforts to expand the scope of consciousness through the notion of the 'extended' mind. This paper examines the varieties of consciousness recognized by Avicenna and several other classical Islamic thinkers with a view to understanding the extent to which their accounts can be mapped on to some of the concepts of consciousness delineated by contemporary philosophers of mind.

Appealing to some analytic tools developed by contemporary analytic philosophers, I discuss Avicenna's views regarding the problem(s) of linguistic and mental reference to non-existents, also known as the problem(s) of 'empty intentionality'. I argue that, according to Avicenna, being in an intentional state directed towards an existing thing involves three elements: (1) an indirect relation to that thing, (2) a direct relation to a mental representation of that thing, and (3) a direct relation to the essence of that thing. Empty intentionality does not involve the first element. Moreover, depending on the nature of the non-existent we are thinking about, the third element may not be involved either. Thus, the necessary element of being in an intentional state towards something is to be related to a mental representation of that thing. The nature of this representation may vary depending on the nature of the non-existent towards which our thought is directed. [ABSTRACT FROM AUTHOR]

In Thinking with Assent: Renewing a Traditional Account of Knowledge and Belief, Maria Rosa Antognazza offers a historical narrative of pre-modern epistemology. She argues that until very recently, philosophers generally held that "knowing and believing are distinct in kind in the strong sense that they are mutually exclusive mental states". This paper tests, and ultimately confirms, that account by applying it two thinkers of the Islamic world, al-Fārābī (d.950 CE) and Ibn Sīnā (Avicenna, d.1037 CE). It is shown that both of them used the term 'assent (taṣdīq)' as an umbrella term covering two very different states, knowledge and belief. In the case of Ibn Sīnā, this contrast is ultimately tied to his sharp distinction between immaterial intellective thinking and embodied thinking that uses a physical organ. [ABSTRACT FROM AUTHOR]

Many scholars consider Avicenna’s theory of cognitive forms a theory of representation, which raises two questions. First, why does a cognitive form represent a particular object instead of another? This issue is known as the determination problem. Second, what is the nature of intentionality of the cognitive form? This is known as the nature problem. This paper examines Avicenna’s theory of cognitive forms and focuses on how he would address the two problems. I argue that Avicenna offers a pluralistic approach to the determination problem: depending on the type of representation, the object of representation is determined differently. Additionally, Avicenna views the nature of intentionality as a referential relation towards the object that can be attributed to the representation in virtue of the object somehow existing in the subject immaterially.

Many later thinkers in the Islamic world pick up on, and further expand, the idea of intuition (ḥads) as they react to Avicenna (Ibn Sīnā). Focusing on figures from the twelfth–thirteenth century, in this paper we will focus especially on the following points of debate: (1) Avicenna's idea that intuition is distingiushed from normal (discursive) thought by lacking 'motion', (2) The question of how and why different individuals differ in the extent of their intuition, (3) The role of intuitive thought in grounding knowledge: is intuition needed every time a certain item of knowledge is grasped for the first time, and hence without a teacher; and further, is intuition needed as an ultimate justification for all non-intuitive knowledge?

The logical rule of contraposition as applied to a particular affirmative proposition (I-contraposition), despite its rejection in the medieval Latin logic, had a different history in the medieval Arabic logic, varying from common acknowledgement to total dismissal (it was accepted by Avicenna and by all of his followers in the eleventh and twelfth centuries and rejected by all of Arabic logicians in the late thirteenth century onwards). This paper is a narrative of the fate of I-contraposition in the early Arabic logic. I will study Avicenna's, al-Suhrawardī's, al-Rāzī's, al-Kashshī's, and al-Khūnajī's views on this rule. Although Avicenna explicitly acknowledged I-contraposition in a brief note, and in an apparently Meinongian language, the other four figures found I-contraposition problematic and listed some counterexamples to it. Nonetheless, they all attempted to justify Avicenna's acceptance of the rule by restricting its application conditions. These efforts led to interesting syntactic and semantic analyses but gathered little attention from later medieval logicians. Finally, in the middle Arabic logic, the revised versions of I-contraposition were also declared invalid. [ABSTRACT FROM AUTHOR]

Essentialism can be defined as a metaphysical theory according to which things have essential and accidental properties. In this paper, I will address Avicennian essentialism, that is, essentialism as we find it in Avicenna's own writings and the writings of the immediate post-Avicennian philosophical tradition of the Islamic world. I will consider a number of primary sources, summarize the state of recent scholarship regarding Avicennian metaphysics of attributes, and I will draw comparisons between Avicennian essentialism and modern essentialism. As a result, I will show that Avicennians endorse two different types of essentialism: conceptualist essentialism and de re essentialism. Avicennian conceptualist essentialism only applies to kinds, while Avicennian de re essentialism only applies to particular individuals. [ABSTRACT FROM AUTHOR]

In his Kitāb al-Burhān (Book of Demonstration), Avicenna discusses a theoretical framework broadly inspired by Aristotle's Posterior Analytics which brings together logic, epistemology and metaphysics. One of the central questions explored in the book is the problem of the relation between knowledge, certainty and causal explanation. Burhān 1.8, in particular, is devoted to the analysis of how certainty comes about in causal as opposed to non-causal contexts. The distinction is understood in Avicenna's system as one between cases in which the conclusion of an argument is warranted only in virtue of an appropriate middle term, and cases in which there is no such intermediary because the predicative link between subject and predicate of the conclusion is immediate. In this context, Avicenna makes use of the case of relative terms (muḍāfāt) to clarify certain crucial aspects of his theory. The paper explores this discussion and shows how Avicenna's account of the relatively marginal role of relatives in the context of demonstration depends on insights that are central to his metaphysics and epistemology.

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. [ABSTRACT FROM PUBLISHER]
