Al-Farabi, Avicenna and Averroes, widely known classical rationalists in the Arabic/Islamic philosophical tradition and strongly infl uential sources for Latin philosophy in the High Middle Ages, all thought themselves to be following Aristotle’s lead regarding the intellectual abstraction of intelligibles in the formation of necessary and unchanging scientific knowledge. For Aristotle it is clear that sensation is a potentiality for apprehending or coming to be individual sensed objects found in the world exterior to the human soul. This takes place (...) by way of a separation of the forms of sensibles from matter and a reception of them as an actualization of the senses of the soul. 1 In an analogous fashion, intellectual knowing is a potentiality for apprehending or coming to be in act non-individuated intellectual forms that are somehow in individuated particular sensible things. Although Aristotle says that “the objects of thought are in the sensible forms”, the analogy with sensation breaks down when it comes to the objects intellectually known. The reason for this is that the nonindividuated or universal forms of human knowledge are not in the sensibles in act as they must be in the intellect. 2 Again following Aristotle De Anima 3.4 and 3.5, these thinkers hold for a part of intellect that is passive or receptive of all things and another part that is active in making all things, this latter described as a disposition like light, this as well describing the active agent as acting like light. This second part, which the Arabic tradition called the Agent Intellect, sometimes describing it also as Active Intellect, al-‘aql al-fa‘il, was understood per Aristotelem to be an eternal cause of the intellectual forms in the human intellect. It was accepted that, without a grounding in separate eternal intellect, there may well be generalization or abstraction – in some sense of the 57term? but scientific knowledge understood as true, necessary and unchanging will not be achieved. 3 Of course, in Posterior Analytics 2.19 Aristotle writes of sensory experience and provides the image of a retreat gradually coming to a halt, saying, “The soul is so constituted that it is capable of the same sort of process”. This process somehow establishes the universal in the soul even though perception is of the particular. He describes this as taking place by induction, writing, “Clearly then it must be by induction that we acquire knowledge of the primary principles, because this is also the way in which general concepts are conveyed to us by sense-perception.” These are “first things” or primary principles or premises required by demonstration. And the Arabic tradition understood Aristotle to hold for the necessity of demonstration in the formation of scientific knowledge, something that stringently requires not only proper syllogistic form but also first premises that are known to be true, not just supposed or simply generalized on the basis of experience. 4 For the Arabic tradition, Aristotle?s doctrine of intellectual understanding required the involvement of that separate Agent Intellect to provide a solid foundation for human scientific knowledge by way of intellectual abstraction.

Al-Fârâbî’s thought on intellect was known to the Latin West through the translation of his Letter on the Intellect, through the Long Commentary on the De Anima by Averroes and through some other works. Al-Fârâbî identified the active power of intellect in Aristotle’s De Anima 3.5 as the unique and separately existing Agent Intellect, but the role of the Agent Intellect in forming intelligibles in act in the human soul is by no means unequivocally clear. Further, the apprehension of intelligibles (...) by human beings and the intellectual development of the soul, oftentimes described as an activity of abstracting (intaza`a), seems to be a genuineabstraction from experience, yet it somehow involves the emanative power of the Agent Intellect. This paper works to provide a coherent explanation of the natureof abstraction and the role of Agent Intellect in that activity. (shrink)

After a very brief introduction, Davidson begins with an informed and detailed account of the views of Aristotle and his major commentators, whose writings had enormous influence on the development of the medieval traditions. Davidson's account is supplemented with a critical exposition of the relevant teachings from the Plotiniana Arabica, from al-Kindi, and from a treatise on the soul attributed to Porphyry in the Arabic tradition. Impressive as all this is, it is simply stage setting for Davidson's detailed accounts of (...) the doctrines and arguments of al-Farabi, Avicenna, and Averroes. (shrink)

Este artículo explica la comprensión de Averroes sobre el entendimiento humano y la abstracción en estos tres comentarios al De Anima de Aristóteles. Mientras que las visiones de Averroes sobre la naturaleza del intelecto material humano cambian a través de tres comentarios hasta que alcanza su famosa visión de la unidad del intelecto material como uno para todos los seres humanos, su visión del intelecto agente como 'forma para nosotros' se sostiene a través de estas obras. En su Gran comentario (...) al De Anima revela su dependencia ante Al Farabi por esta noción y provee una crítica detallada de la noción farabiana que sostiene que el intelecto agente es 'forma para nosotros' sólo como causa agente, no como verdadera causa formal. Aunque Averroes sostiene que el intelecto agente debe, de alguna manera, ser intrínseco a nosotros como nuestra forma, ya que los humanos son racionales per se y emprenden actos de conocimiento por voluntad, se muestra que su visión se funda en un uso equívoco de la noción de causa formal. El intelecto agente no puede ser propiamente nuestro principio intrínseco formal mientras permanezca ontológicamente separable. (shrink)

Examines one of the most exciting and dynamic periods in the development of medieval Islam, from the late 9th to the early 11th century, through the thought of five of its principal thinkers, prime among them al-Farabi. This great Islamic philosopher, called 'the Second Master' after Aristotle, produced a recognizable school of thought in which others pursued and developed some of his own intellectual preoccupations. Their thought is treated with particular reference to the most basic questions which can be (...) asked in the theory of knowledge or epistemology. The book thus fills a lacuna in the literature by using this approach to highlight the intellectual continuity which was maintained in an age of flux. Particular attention is paid to the ethical dimensions of knowledge. (shrink)

This article explicates Averroes's understanding of human knowing and abstraction in this three commentaries on Aristotle's De Anima. While Averroes's views on the nature of the human material intellect changes through the three commentaries until he reaches is famous view of the unity of the material intellect as one for all human beings, his view of the agent intellect as 'form for us' is sustained throughout these works. In his Long Commentary on the De Anima he reveals his dependence on (...) al-Fârâbî for this notion and provides a detailed critique of the Farabian notion that the agent intellect is 'form for us' only as agent cause, not as our true formal cause. Although Averroes argues that the agent intellect must somehow be intrinsic to us as our form since humans are per se rational and undertake acts of knowing by will, his view is shown to rest on an equivocal use of the notion of formal cause. The agent intellect cannot be properly our intrinsic formal principle while remaining ontologically separate. (shrink)

The Arabic philosophical tradition played an important role in the formation of theological, philosophical and scientific thought in medieval Europe subsequent to the translations from Arabic into Latin in the 12th and 13th centuries. The influence of that Arabic classical rationalist tradition in works by al-Farabi, Avicenna, Averroes and the Liber de causis is evident in the thought of Thomas Aquinas, though the breadth and depth of that influence is often insufficiently noted and explained by scholars of Aquinas. This (...) course focuses on the metaphysics, epistemology and psychology of Aquinas in the development of his philosophical conceptions of soul and intellect in the context of his use of sources in Aristotle and works by philosophers of the Arabic tradition, particularly Avicenna and Averroes. Readings are selected from writings from each of the four major periods of his career starting with his first major work, the Commentary on the Sentences. The course was planned to be taught at Marquette, Katholieke Universiteit Leuven and the Universidad Panamericana as a hybrid course. That is, it was taught using online tools and resources and also in the classroom with face-to-face meetings once per week. And it was taught at Marquette, KU Leuven and the Universidad Panamericana simultaneously. On Thursdays students met online with video and audio for questions and discussion with Profs. Taylor, Robiglio and López-Farjeat and the student groups in Milwaukee, Leuven and Mexico City live. (shrink)

Al-Farabi and His School examines one of the most exciting and dynamic periods in the development of medieval Islam: the period which ran from the late ninth century to the early eleventh century AD. This age is examined through the thought of five of its principal thinkers and named after the first and greatest of these as the "Age of Farabism." Ian Richard Netton demonstrates that the great Islamic philosopher al-Farabi (870-950), called "the Second Master" after Aristotle, (...) produced a recognizable school of thought. This school of thought, which Netton refers to as the "School of al-Farabi," was influenced by the thought of Plato, Aristotle, and Plotinus. Yet, it was much more than a mere clone of Greek thought. The originality and independence of thought expressed by such adherents as Yahya b. Adi, Abu Sulayman al-Sijistani, al-Amiri and Abu Hayyan al-Tawhidi is described, appreciated, and critically assessed in this volume, with an emphasis given to the fundamentals of epistemology. Al-Farabi and His School is unique in its examination of the intellectual continuity that was maintained in an age of flux, and its particular emphasis on the ethical dimensions of knowledge.

The Exchange of Words is a philosophical exploration of human testimony, specifically as a form of intersubjective understanding in which speakers communicate by making themselves accountable for the truth of what they say. This account weaves together themes from philosophy of language, moral psychology, action theory, and epistemology, for a new approach to this basic human phenomenon.

The paper argues for the centrality of believing the speaker (as distinct from believing the statement) in the epistemology of testimony, and develops a line of thought from Angus Ross which claims that in telling someone something, the kind of reason for belief that a speaker presents is of an essentially different kind from ordinary evidence. Investigating the nature of the audience's dependence on the speaker's free assurance leads to a discussion of Grice's formulation of non-natural meaning in an epistemological (...) light, concentrating on just how the recognition of the speaker's self-reflexive intention is supposed to count for his audience as a reason to believe P. This is understood as the speaker's explicitly assuming responsibility for the truth of his statement, and thereby constituting his utterance as a reason to believe. (shrink)

In this volume Rorty offers a Deweyan account of objectivity as intersubjectivity, one that drops claims about universal validity and instead focuses on utility for the purposes of a community. The sense in which the natural sciences are exemplary for inquiry is explicated in terms of the moral virtues of scientific communities rather than in terms of a special scientific method. The volume concludes with reflections on the relation of social democratic politics to philosophy.

Richard Swinburne offers an original treatment of a question at the heart of epistemology: what makes a belief rational, or justified in holding? He maps the rival accounts of philosophers on epistemic justification ("internalist" and "externalist"), arguing that they are really accounts of different concepts. He distinguishes between synchronic justification (justification at a time) and diachronic justification (synchronic justification resulting from adequate investigation)--both internalist and externalist. He also argues that most kinds of justification are worth having because they are (...) indicative of truth; however, it is only justification of internalist kinds that can guide a believer's actions. Swinburne goes on to show the usefulness of the probability calculus in elucidating how empirical evidence makes beliefs probably true. (shrink)

This paper explores some aspects of the relation between different ways of achieving a consensus on the judgemental values of a group of indviduals; in particular, aggregation and deliberation. We argue firstly that the framing of an aggregation problem itself generates information that individuals are rationally obliged to take into account. And secondly that outputs of the deliberative process that this initiates is in tension with constraints on consensual values typically imposed by aggregation theory, at least when deliberation is modelled (...) as process of learning from others compatible with Bayesian updating principles.

"Al-Farabi of Baghdad (c. 870-950) is the first major representative of the medieval Arabic Aristotelianism which came to influence the Christian West so profoundly. In the Islamic world his writings on logic set the pattern for the future and virtually created Islamic philosophy. He is also important as a witness to the study of Aristotle in late antiquity, demonstrating a knowledge of Galen and the exegetical tradition of Porphyry. This translation is based on a fresh study of the Arabic (...) manuscripts. An introduction and notes make this intriguing document accessible to all for whom it contains important matter.Classicists, historians of philosophy and logic, medievalists, Arabists, students of Islamic thought."--.

Atheism is a familiar kind of skepticism about religion. Moral error theory is an analogous kind of skepticism about morality, though less well known outside academic circles. Both kinds of skeptic face a "what next?" question: If we have decided that the subject matter (religion/morality) is mistaken, then what should we do with this way of talking and thinking? The natural assumption is that we should abolish the mistaken topic, just as we previously eliminated talk of, say, bodily humors and (...) unicorns. The fictionalist, however, offers a less obvious recommendation. According to the fictionalist, engaging in the topic in question provides pragmatic benefits that do not depend on its truth-in a way roughly analogous to engaging with a novel or a movie. The religious fictionalist maintains that even if we were atheists, we should carry on talking, thinking, and acting as if religion were true. The moral fictionalist maintains a similar view regarding moral talk, thought, and action. Both forms of fictionalism face serious challenges. Some challenges can be levelled at either form of fictionalism (or at any form of fictionalism), whereas others are problems unique to moral fictionalism or to religious fictionalism. There are important questions to be asked about the relationship between these two kinds of fictionalism. Could moral fictionalism be plausible even if religious fictionalism is not (or vice versa)? This is a volume of thirteen previously unpublished papers on the topics of religious fictionalism, moral fictionalism, and the relation between these views. (shrink)

This book brings together twenty articles giving a comprehensive view of the work of the Aristotelian commentators.... The importance of the commentators is partly that they represent the thought and classroom teaching of the Aristotelian and Neoplatonist schools and partly that they provide a panorama of a thousand years of anicient Greek philosophy, revealing many original quotations from lost works. Even more significant is the profound influence... that they exert on later philosophy, Islamic and Western. Not only did they preserve (...) anti-Aristotelian marterial which helped inspire Medieval and Renaissance science, but they presented Aristotle in a form that made him acceptable to the Christian Church. It is not Aristotle, but Aristotle transformed and embedded in the philosophy of the commentators, that so often lies behind the views of later thinkers. --From book jacket. (shrink)

Richard Swinburne presents a powerful new case for substance dualism and for libertarian free will. He argues that pure mental events are distinct from physical events and interact with them, and claims that no result from neuroscience or any other science could show that interaction does not take place. Swinburne goes on to argue for agent causation, and claims that it is we, and not our intentions, that cause our brain events. It is metaphysically possible that each of us (...) could acquire a new brain or continue to exist without a brain; and so we are essentially souls. Brain events and conscious events are so different from each other that it would not be possible to establish a scientific theory which would predict what each of us would do in situations of moral conflict. Hence, we should believe that things are as they seem to be: that we make choices independently of the causes which influence us. It follows that we are morally responsible for our actions. (shrink)

Philosophy and literature enjoy a close, complex relationship. Elucidating the connections between these two fields, this book examines the ways philosophy deploys literary means to advance its practice, particularly as a way of life that extends beyond literary forms and words into physical deeds, nonlinguistic expression, and subjective moods and feelings.

_Heidegger_ is a classic introduction to Heidegger's notoriously difficult work. Truly accessible, it combines clarity of exposition with an authoritative handling of the subject-matter. Richard Polt has written a work that will become the standard text for students looking to understand one of the century's greatest minds.

The book begins with an overview that introduces the Theorem and the issues surrounding it, and explores how the essays that follow contribute to our understanding of those issues.
