Some authors have proposed that Avicenna considers mathematical objects, i.e., geometric shapes and numbers, to be mental existents completely separated from matter. In this paper, I will show that this description, though not completely wrong, is misleading. Avicenna endorses, I will argue, some sort of literalism, potentialism, and finitism.

A pesar de los reparos de algunos especialistas, Avicena es un punto de referencia insoslayable en la historia de la intencionalidad. Este trabajo se propone determinar la manera en que el intelecto toma posición con respecto a la realidad de los objetos con los que se relaciona. Abordamos la relación intencional centrando nuestra atención en el nexo entre lógica y ontología y enfatizando el papel que juegan la conceptualización y la estimación en la determinación de lo que es real y (...) existente efectivamente. La exploración de la estructura intencional nos lleva a identificar la relevancia de la doctrina de las esencias como presupuesto fundamental para la conceptualización y la verdad. La importancia de la teoría de la intencionalidad de Avicena radica en la descripción tanto de la referencia al objeto de conocimiento, como un proceso que avanza de lo conocido a lo desconocido, cuyas diversas fases conforman el itinerario de las esencias. Desde este punto de vista, la realidad y la existencia son accidentes que le acaecen a las esencias. Las capacidades del alma que hacen posible la referencia intencional son la estimativa, la conceptualización y el asentimiento. Asimismo, identificamos algunos puntos de convergencia entre las doctrinas de las esencias de Avicena y de Husserl. (shrink)

There is a disagreement among contemporary commentators about Avicena's view of the theoretical intellect in "Kitāb alnafs". Is its activity performed by an internal sense helped by the intellect, or is it a activity proper of the intellect independently of material forms? Some passages of V.5 and V.6 suggest that both elements are necessary to the knowledge: unifying the multiplicity and multiplying the unity; in others words, it is not enough that the intellect conceptualizes the minor and major terms of (...) the syllogism, it also needs to intuit the middle term.

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. (shrink)

Intentionality (‘directedness’, ‘aboutness’) is both a central topic in contemporary philosophy of mind, phenomenology and the cognitive sciences, and one of the themes with which both analytic and Continental philosophers have separately engaged starting from Brentano and Edmund Husserl’s ground-breaking Logical Investigations (1901) through Roderick M. Chisholm, Daniel C. Dennett’s The Intentional Stance, John Searle’s Intentionality, to the recent work of Tim Crane, Robert Brandom, Shaun Gallagher and Dan Zahavi, among many others. In this paper, I shall review recent discussions (...) of intentionality, including some recent explorations of the history of the concept (paying particular attention to Anselm), and suggest some ways the phenomenological approach of Husserl and Heidegger can still offer insights for contemporary philosophy of mind and consciousness.

Avicenna’s logical theory of negative judgement can be seen as a systematic development of the insights Aristotle had laid out in the De interpretatione. However, in order to grasp the full extent of his theory one must extend the examination from the logical works to the metaphysical and psychological bases of negative judgement. Avicenna himself often refrains from the explicit treatment of the connections between logic and metaphysics or psychology, or treats them in a rather oblique fashion. Time and again (...) he is satisfied with noting that this or that question is not proper for a logician and should be dealt with in metaphysics or psychology—without bothering to refer his reader to the exact loci. The following is an attempt at a reconstruction of Avicenna’s theory of negative judgement in such a broad fashion. I will begin with his analysis of negative judgement as resulting from an operation of ‘removing’ the predicate term from the subject term. On this basis, I will move on to discuss how he conceives of the relation between negative judgements and affirmative judgements that contain privative or metathetic terms as well as the question of whether negative judgements can be reduced to affirmative ones. Having thus laid out his logical theory of negation, I move on to discuss the underlying metaphysics by looking at the relation between existence and non-existence, and existence and privation. Finally, I will address Avicenna’s scattered psychological remarks on how we can conceive of what does not exist. (shrink)

Brentano claims to have taken his idea of intentionality from scholastic thought. However, in St. Thomas Aquinas, intentionality is not just the mark of knowledge, although some scholastics have interpreted it this way, even during Brentano’s lifetime. Moreover, to elaborate his idea of intentional presence, the German philosopher was not only inspired by him, but also by Francisco Suárez. In an unpublished manuscript from his legacy, Brentano understands Suarez’s objective concept as a representation of the thing in the psyche. Thus, (...) even before writing his definitive doctoral thesis, Brentano maintained that the object of thought is not the external thing but its mental copy. In short, modern philosophy seems to have been more decisive than scholasticism in shaping the substance of his theory of intentionality. (shrink)

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.

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...

The idea that intentionality is the distinctive mark of the mental or that only mental phenomena have intentionality emerged in the philosophical tradition after Franz Brentano. Much of contemporary philosophy is dedicated to a rejection of the view that mental phenomena have original intentionality. In other words, main strands of contemporary philosophy seek to naturalize intentionality of the mental by tracing it to linguistic intentionality. So in order to avoid the problematic claim that a physical phenomenon can in virtue of (...) its own physical structure mean exactly one thing, they adopt a form of holism. Nevertheless, contemporary philosophers are attracted to a naturalist story about the emergence of the logical space. In this work, I am interested in the naturalism and the holism advocated by Wilfrid Sellars and developed by the Pittsburgh school. It is not only a view that I find theoretically attractive but I also admire it for its fecund engagement with the history of philosophy, especially the work of Georg Wilhelm Friedrich Hegel and, as I will argue, Abū Nas̩r Muḥammad al-Fārābī (Alfarabi).

This thesis addresses three challenges posed by intentionality - the ability of our mental states and language to be about something - to a logician: an apparent reference to non-existent objects, intentional indeterminacy and the failure of substitutivity of coextensive terms in an intentional context. Since intentionality plays an important role in our everyday reasoning, a proper formal account of it is highly desirable, yet it requires a departure from classical logic. One can modify classical logic and adapt the formal (...) apparatus to account for the aforementioned problems (Graham Priest’s logic for intentionality serves as an example of such an approach in this work) or one can make an even more radical shift and seek for inspiration in a different logical tradition like the terminist logic developed in the Late Middle Ages by figures like William of Ockham or John Buridan. The second path is explored here as a modest attempt to show that once we abandon the bias against the history of logic as irrelevant, we can actually get access to firm logical solutions inaccessible from a classical perspective, while still practising logic proper.
