In his Kitāb al-Burhān, Avicenna discusses a theoretical framework broadly inspired by Aristotle's Posterior Analytics which brings together logic, epistemology and metaphysics. One of the central questions explored in the book is the problem of the relation between knowledge, certainty and causal explanation. Burhān 1.8, in particular, is devoted to the analysis of how certainty comes about in causal as opposed to non-causal contexts. The distinction is understood in Avicenna's system as one between cases in which the conclusion of an (...) argument is warranted only in virtue of an appropriate middle term, and cases in which there is no such intermediary because the predicative link between subject and predicate of the conclusion is immediate. In this context, Avicenna makes use of the case of relative terms to clarify certain crucial aspects of his theory. The paper explores this discussion and shows how Avicenna's account of the relatively marginal role of relatives in the context of demonstration depends on insights that are central to his metaphysics and epistemology.

This study is the first part of an attempt to settle a vigorous debate among historians of medieval philosophy by harnessing the resources of analytic philosophy. The debate is about whether Avicenna's epistemology is rationalist or empirical. To settle the debate, I first articulate in this article the three core theses of rationalism and one core thesis of empiricism. Then, I probe Avicenna's epistemology in his major works according to the first core thesis of rationalism (the intuition thesis). In the (...) end, I find Avicenna committed to this thesis in at least one substantive way, namely, in his claim to intuit the intelligible forms or essences. This suffices to count Avicenna as rationalist. In a subsequent article, I shall probe Avicenna's epistemology according to the other two core theses of rationalism, presenting further evidence that he was a rationalist, not an empiricist.

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.

This thesis is concerned with answering the question, what is the central argument of Avicenna’s Metaphysics of the Healing that brings its opening ontological approach to the subject of first philosophy to its ultimate theological goal and conclusion? This dissertation contends that it is the function of the fundamental scientific first principles of metaphysics, and in particular the fundamental primary notion necessary, to provide the intelligible link that Avicenna employs to demonstrate the existence and true-nature of the divine necessary existence (...) in itself on the basis of his doctrine of being. This conclusion is pursued through a systematic and cumulative line of inquiry that begins in Part I with Avicenna’s logical–cum–epistemological doctrine of conceptualization and assent, the heuristic order of the basic scientific questions, and his theory of a demonstrative science. The thesis then moves from the wider concentric circles concerned with logical matters into a series of narrowing concentric circles pertaining to the scientific order of the MH. Part II presents a close analysis of the Metaphysics of the Healing’s novel reception and reorganization of Aristotelian metaphysics according to Avicenna’s theory of demonstrative science, which consists in a subject, scientific first principles, and objects of inquiry that includes the species, proper accidents, and the science’s ultimate goal which is the aitiological–cum–theological inquiry into the causes of being. Part III transitions into a still narrower set of concentric circles that provide a detailed explication of the formal and material aspects of the scientific first principles of the Metaphysics of the Healing. Finally, the main argument of the thesis reaches the central point and question of the dissertation in Part IV, which establishes the fundamentality of the primary notion the necessary in the ontology, aitiology, and theology of the Avicenna’s Metaphysics of the Healing. Part IV concludes that the principal function of the fundamental primary notion the necessary is to provide the intelligible link that connects Avicenna’s doctrine of being with the divine necessary existence in itself.
