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. (shrink)

Elucidating a metaphysics of medicine is vital for framing a coherent medical ethics. In this paper, I examine the historical case of Avicenna, the eleventh century physician-philosopher. Avicenna radicalizes the dissective power of reason using a logicized Aristotelian metaphysics to clarify concepts at the metaphysical level, which I call his anatomy of being. One of the practical consequences of Avicenna’s metaphysics is a dehumanizing eschatology of death. I outline the main elements of Avicenna’s thought that constitute his anatomy of being. (...) Through an examination of his logic, metaphysics, and psychology, I show how Avicenna develops a dissective logic. I conclude that one’s epistemology, as a method of knowing, entails a metaphysics, and, in turn, results in an ethical stance to the object of knowledge. For Avicenna, mental dissective logic applied to humans results in dehumanization, thereby destroying the humanistic impulse of medicine. (shrink)

In this article, I defend a version of ontological pluralism, specifically with an eye toward laying metaphysical groundwork for an account of divine naming inspired by Avicenna. I try to show (1) that Avicenna’s pluralism is well-motivated as a metaphysical thesis and (2) that it offers substantive philosophical support for a correlatively pluralist approach to divine naming. My argument proceeds by identifying two influential objections to ontological pluralism, and then offering replies to these objections with the help of Avicenna. The (...) first objection pertains to pluralism as a position in general metaphysics, whereas the second pertains to pluralism as a position in theological epistemology or divine naming. To the extent that these replies are successful, I argue that Avicennian pluralism is compelling on both counts as a philosophical position. (shrink)

This study examines a number of different answers to the question: wheredoes Avicenna demonstrate the existence of God within the Metaphysics of the Healing? Many interpreters have contended that there is an argument for God’s existence in Metaphysics of the Healing I.6–7. In this study I show that such views are incorrect and that the only argument for God’s existence in the Metaphysics of the Healing is found in VIII.1–3. My own interpretation relies upon a careful consideration of the scientific (...) order and first principles of the Metaphysics of the Healing, paying attention to Avicenna’s own explicit statements concerning the goals andintentions of different books and chapters, and a close analysis of the structure ofthe different arguments found in the relevant texts of the Metaphysics of the Healing. I conclude that Avicenna’s explicit goal in I.6–7 is to establish the properties that belong to necessary existence and possible existence, which consists, not in ademonstration of God’s existence, but in a dialectical treatment of the first principlesof metaphysics.

Avicenna's proof for the existence of God (the Necessary Existent) in the Metaphysics of the Salvation relies on the claim that every possible existent shares a common cause. I argue that Avicenna has good reason to hold this claim given that he thinks that (1) every essentially ordered causal series originates in a first, common cause and that (2) every possible existent belongs to an essentially ordered series. Showing Avicenna's commitment to 1 and 2 allows me to respond to Herbert (...) Davidson's and Richard Swinburne's claim that Avicenna's proof for the Necessary Existent is incomplete and fallacious -/- . (shrink)
