15Creation and Eternity in Medieval PhilosophyIn Heather Dyke & Adrian Bardon (eds.), A Companion to the Philosophy of Time, Wiley. 2013.This chapter on creation and eternity in medieval philosophy focuses on arguments for the world's age drawn from the nature of time. To this end, there are four main sections. The first covers proofs for the eternity of the world taken from the nature of time, with an emphasis on Aristotle's original argument for that thesis and then Avicenna's modal version of the proof. The second deals with rejoinders, based upon non‐Aristotelian conceptions of time, to proofs for the eternity of the world wi…Read more

24One Way of AmbiguousAmerican Catholic Philosophical Quarterly 96 (4): 545-570. 2022.This study provides the historical background to, and analysis and translations of, two seminal texts from the medieval Islamic world concerning the univocity of being/existence and a theory of “ambiguous predication” (tashkīk), which is similar to the Thomistic theory of analogy. The disputants are Fakhr al-Dīn al-Rāzī (1149–1210), who defended a theory of the univocity of being, and Naṣīr al-Dīn al-Ṭūsī (1201–1274), who defended the theory of ambiguous predication. While the purported issue is…Read more

23Necessary Existence and the Doctrine of Being in Avicenna’s Metaphysics of the Healing by Daniel D. De HaanJournal of the History of Philosophy 60 (1): 158-160. 2022.Avicenna scholars know well that Avicenna aspired to present his metaphysics in the form of an Aristotelian science. The mélange of topics that make up Avicenna’s Metaphysics often appears disjointed and rambling, making it difficult to see how successful he was in this aspiration. Daniel D. De Haan’s book provides an aerial view of Avicenna’s Metaphysics, which argues that Avicenna succeeded. More specifically, De Haan suggests how Avicenna’s conception of the “necessary” links the general subj…Read more

38A Continuation of Atomism: Shahrastānī on the Atom and ContinuityJournal of the History of Philosophy 57 (4): 595-619. 2019.while it should go without saying, it bears mentioning: the history of atomism in the medieval Islamic East is not the same as that of the medieval Christian West. One simply cannot assume that what is true of the conception of the atom in the West also need be true of the conception of the atom in the East, or even that the two traditions are drawing upon and responding to the same set of literature. In fact, the question is open as to whether these two histories even share a common origin. Whi…Read more

5Medieval Philosophy of ReligionAcumen Publishing. 2013.Volume 2 covers one of the richest eras for the philosophical study of religion. Covering the period from the 6th century to the Renaissance, this volume shows how Christian, Islamic and Jewish thinkers explicated and defended their religious faith in light of the philosophical traditions they inherited from the ancient Greeks and Romans. The enterprise of 'faith seeking understanding', as it was dubbed by the medievals themselves, emerges as a vibrant encounter between - and a complex synthesis…Read more

22A Penetrating Question in the History of Ideas: Space, Dimensionality and Impenetrability in the Thought of AvicennaArabic Sciences and Philosophy 16 (1): 47. 2006.Avicenna's discussion of space is found in his comments on Aristotle's account of place. Aristotle identified four candidates for place: a body's matter, form, the occupied space, or the limits of the containing body, and opted for the last. Neoplatonic commentators argued contra Aristotle that a thing's place is the space it occupied. Space for these Neoplatonists is something possessing dimensions and distinct from any body that occupies it, even if never devoid of body. Avicenna argues that t…Read more

38The study begins with the language employed in and the psychological basis of thought experiments as understood by certain medieval Arabic philosophers. It then provides a taxonomy of different kinds of thoughts experiments used in the medieval Islamic world. These include purely fictional thought experiments, idealizations and finally thought experiments using ingenious machines. The study concludes by suggesting that thought experiments provided a halfway house during this period between a sta…Read more

40Doubts on Avicenna: A Study and Edition of Sharaf al-Dīn al-Mas'ūdī's Commentary on the Ishārāt. by Ayman ShihadehPhilosophy East and West 67 (2): 599-601. 2017.While the little-known thinker Sharaf al-Dīn al-Mas'ūdī may have had doubts concerning the Ishārāt of the great Persian philosopher Avicenna, no one should have doubts concerning Ayman Shihadeh's brilliant Doubts on Avicenna: A Study and Edition of Sharaf al-Dīn al-Mas'ūdī's Commentary on the Ishārāt. Professor Shihadeh's volume is a rich study of Mas'ūdī's alMabāḥith wa-l-shukūk 'alā Kitāb al-Ishārāt, which additionally offers the first critical edition of that work. Doubts on Avicenna affords …Read more

Time and Time Again: A Study of Aristotle and Ibn Sina's Temporal TheoriesDissertation, University of Pennsylvania. 2000.The dissertation examines the temporal theories of Aristotle and the Muslim Aristotelian, Ibn Sina . After considering Aristotelian science and sketching Aristotle's theory of physics, the dissertation picks up a series of puzzles concerning the reality of time. The central puzzle is a dilemma, which seemingly shows that the now can neither change nor remain the same. The dilemma is important, since one's solution to it affects the way one envisions time. Aristotle's solution, I argue, is to sho…Read more

129Scientific Methodologies in Medieval IslamJournal of the History of Philosophy 41 (3): 307-327. 2003.: The present study considers Ibn Sînâ's (Lat. Avicenna) account of induction (istiqra') and experimentation (tajriba). For Ibn Sînâ induction purportedly provided the absolute, necessary and certain first principles of a science. Ibn Sînâ criticized induction, arguing that it can neither guarantee the necessity nor provide the primitiveness required of first principles. In it place, Ibn Sînâ developed a theory of experimentation, which avoids the pitfalls of induction by not providing absolute,…Read more

1What Underlies the Change from Potentiality to Possibility? A Select History of the Theory Matter from Aristotle to AvicennaCadernos de História E Filosofia da Ciência 17 (2). 2007.One of the most fundamental notions in the thought of Aristotle is the distinction between actuality and potentiality, which Aristotle links with the equally fundamental distinction between form and matter respectively. According to Aristotle, form, which brings with it actuality, and matter, which brings with it potentiality, are eternal and as such necessary. Consequently, on Aristotle?s view, neither form nor matter needs an efficient cause for its existence. Later thinkers?both in the Greek …Read more

97The Eternity of the World: Proofs and Problems in Aristotle, Avicenna, and AquinasAmerican Catholic Philosophical Quarterly 88 (2): 271-288. 2014.This study looks at the position of two of the Middle Ages’ towering intellectual figures, Avicenna and Aquinas, and their arguments concerning the age of the cosmos. The primary focus is the nature of possibility and whether possibility is such that God can create it or such that its “existence” has some degree of independence from God’s creative act. It is shown how one’s answer to this initial question in turn has enormous ramifications on a number of other, core theological topics. These iss…Read more

20Making Abstraction Less Abstract: The Logical, Psychological, and Metaphysical Dimensions of Avicenna’s Theory of AbstractionProceedings of the American Catholic Philosophical Association 80 169-183. 2006.A debated topic in Avicennan psychology is whether for Avicenna abstraction is a metaphor for emanation or to be taken literally. This issue stems from the deeper philosophical question of whether humans acquire intelligibles externally from an emanation by the Active Intellect, which is a separate substance, or internally from an inherently human cognitive process, which prepares us for an emanation from the Active Intellect. I argue that the tension between thesedoctrines is only apparent. In …Read more
