One of the chief innovations in medieval adaptations of Aristotelian psychology was the expansion of Aristotle's notion of imagination orphantasiato include a variety of distinct perceptual powers known collectively as the internal senses. Amongst medieval philosophers in the Arabic world, Avicenna offers one of the most complex and sophisticated accounts of the internal senses. Within his list of internal senses, Avicenna includes a faculty known as “estimation”, to which various functions are assigned in a wide variety of contexts. Although many (...) philosophers in the Arabic world as well as in the Latin West accepted Avicenna's positing of an estimative faculty, Avicenna's best-known critics, al-Ghazâlî and Averroes, found Avicenna's arguments in support of a distinct estimative faculty problematic. For different reasons, both Averroes and Ghazâlî raised the basic question of whether one needed to posit a distinct faculty of estimation to supplement the perceptual abilities of the other internal senses, and whether the notion of an estimative power as defined by Avicenna was internally coherent. Such criticisms suggest that the Avicennian conception of estimation is not entirely unambiguous, and that a correct understanding of Avicenna's motivations for delineating an estimative power requires a careful study of the diverse activities assigned to it throughout Avicenna's philosophical writings.

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.

The concept of ‘‘certitude” is central in Arabic discussions of the theory of demonstration advanced by Aristotle in the Posterior Analytics. In the Arabic tradition it is ‘‘certitude,” rather than ‘‘knowledge”, that is usually identified as the end sought by demonstrations. Al-Fārābī himself devotes a short treatise, known as the Conditions of Certitude, to determining the criteria according to which a subject can claim to have absolute certitude of any proposition. In this article the author traces the roots of the (...) concept of certitude to the Arabic translation of the Posterior Analytics. She then offers a close reading of the text of al-Fārābī's Conditions and its parallels in his Epitome of the Posterior Analytics. She argues that the identification of certitude as a cognitive state distinct from knowledge enabled al-Fārābī to introduce a number of interesting and sometimes problematic innovations into Arabic epistemology. Foremost amongst his positive innovations is the recognition that contingent as well as necessary propositions allow for an attenuated form of certitude, and the introduction of reliabilism into the justification of claims to certitude. But al-Fārābī is also one of the first philosophers to articulate explicitly the idea that certitude must include an element of ‘‘knowing that one knows,” a controversial principle that tends to undermine both al-Fārābī’s reliabilism and his efforts to loosen some of the strictures in traditional Aristotelian epistemology.

L'A. presenta un'analisi della Lettera sull'anima, in cui Avicenna affronta il tema delle idee di esseri fittizi, come la fenice, ed in particolare la permanenza di tali idee nell'anima dopo la sua separazione dal corpo. Nella parte centrale dello studio l'A. esamina il rapporto fra la risposta avicenniana al problema ed alcuni elementi dottrinali caratterizzanti il pensiero del filosofo: il tema degli universali, della quidditas, o natura comune, e la distinzione fra essenza ed esistenza.

La prima parte dello studio verte sulla critica avanzata da Tommaso contro la dottrina averroista dell'unità dell'intelletto, e nello specifico contro l'idea che l'intelletto materiale funzioni come soggetto degli intelligibili, cioè come «colui che conosce» i pensieri intelligibili. Tale critica è presente sia nel De unitate sia nella Sententia libri De anima. La seconda parte dello studio verte sul pensiero di Averroè relativo all'intellezione, e su diverse posizioni tenute dal filosofo in relazione all'intelletto materiale . L'esame critico del tema dell'intelletto (...) materiale investe anche altre problematiche speculative affrontate dal filosofo, in particolare la famosa tesi del doppio soggetto, che l'A. indaga alla luce dell'analisi ilomorfica degli intellegibili . Infine, l'A. prende in esame il tema del medium invocato da Averroè per la spiegazione razionale del fenomeno della sensazione, e analizza il parallelismo tracciato dallo stesso Averroè fra il ruolo del medium nelle sensazioni e quello dell'intelletto materiale nelle intellezioni, sviluppato soprattutto nel Commento grande al De anima.

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.

There are surprisingly few texts in which Avicenna discusses our knowledge of separate substances. The most extensive account occurs in Metaphysics 3.8, a text which was cited by Aquinas in a small number of works from relatively early in his academic career. Aquinas’s attitude to Avicenna’s account, which he dubbed knowledge per impressionem, is by no means uniform, even within a single work. Sometimes Avicenna is an adversary; sometimes he is an ally; still other times he is an innocent bystander. (...) I explore the reasons for Aquinas’s shifting evaluation of Avicenna’s theory and show that Aquinas’s attitude depends in part upon whether the separate substance in question is God or the angels, and whether he is considering the soul as separated or embodied. Ultimately I argue that Aquinas’s abandonment of knowledge per impressionem reflects his general move away from any Avicennian influences that smack of dualism in his eyes. (shrink)

Ralph McInerny's translation of Aquinas's polemical opusculum, De unitate intellectus contra Averroistas, is part of a new series of texts whose purpose is, as the cover announces, to "present well-edited basic texts to be used in courses and seminars and for teachers looking for a succinct exposition of the results of recent research." McInerny's volume, with its facing page Latin text and English translation, fulfills the first goal in exemplary fashion; but the interpretive essays fall somewhat short of presenting "up-to-date (...) commentary" on Aquinas's text and the positions it attacks.

The Remarks and Admonitions is one of the last works written by the Islamic philosopher Avicenna. Like his more familiar works, the Shifa' and the Najah, this work covers the entire scope of theoretical philosophy, with its first three parts being devoted to logic, physics, and metaphysics, respectively. Part Four of this work is unique, however, since it moves outside the confines of philosophy and takes up the topic of mysticism, employing concepts and terms familiar from the tradition of Sufism. (...) Following upon her excellent translation and study of the first part of this work over a decade ago, Shams Inati has here provided students of Islamic philosophy with another fine and readable translation of Part Four, together with an extensive introduction detailing the contents of the work and its parallels with other Avicennian texts.
