According to a common reading, Spinoza and Leibniz stand on opposite ends of the modal spectrum. At one extreme lies ‘‘Spinoza the necessitarian,’’ for whom the actual world is the only possible world. At the other lies ‘‘Leibniz the anti-necessitarian,’’ for whom the actual world is but one possible world among an infinite array of other possible worlds; the actual world is privileged for existence only in virtue of a free decree of a benevolent God. In this paper, I challenge (...) both of these readings. Spinoza is no necessitarian and Leibniz is no anti-necessitarian – at least as these characterizations are usually understood. Rather, I contend, Spinoza and Leibniz are both anti-essentialists; they believe that the modality of objects can vary relative to how those objects are conceived. This shared commitment to anti-essentialism allows them to consistently affirm both necessitarianism and its denial, relative to different ways of conceiving the world. Their embrace of this modal theory, I further argue, is grounded in their similar views on metaphysical perfection, ontological plentitude, and the principle of sufficient reason. (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)

This article is about Avicenna’s account of syllogisms comprising opposite premises. We examine the applications and the truth conditions of these syllogisms. Finally, we discuss the relation between these syllogisms and the principle of non-contradiction.

This book collects six unpublished and published academic studies on the thought of Francisco Suárez, which is addressed through accurate textual analyses and meticulous contextualization of his doctrines in the Scholastic debate. The present essays aim to portray two complementary aspects coexisting in the work of the Uncommon Doctor: his innovative approach and his adherence to the tradition. To this scope, they focus on some pivotal, but often neglected, topics in Suárez’s metaphysics and psychology – such as his theories of (...) cognition and truth, angelology, continuous quantity – thereby developing an original inquiry into a crucial moment in the development of Western philosophy.

Abstract. Scholars have long debated the possibility of a mystical or illuminationist strain of thought in Ibn Sīnā 's body of writing. This debate has often focused on the meaning and contents of his partly lost work al-Mashriqiyyūn (The Easterners), also known as al-Ḥikma al-Mashriqiyya (EasternWisdom), mentioned by Ibn Sīnā himself as well as by numerous Western writers including Ibn Rushd and Ibn Ṭufayl. A handful of references to what is called Ibn Sīnā 's “Oriental Philosophy” are also found in (...) the Castilian and Hebrew works of the Castilian Jew Abner of Burgos (ca. 1270-ca.1347), known after his conversion to Christianity as Alfonso of Valladolid. Although the content of these citations has not been identified, it has been proposed that they may preserve otherwise unknown passages from Ibn Sīnā's lost work. This study considers the references to Ibn Sīnā 's so-called “Oriental Philosophy” within Abner's writings and concludes that rather than preserving lost passages from Ibn Sīnā's writing, Abner's references were drawn primarily from Ibn Ṭufayl and offer no support for the argument of a possible mystical or illuminationist strain in Ibn Sīnā 's thinking. -/- Résumé. Depuis longtemps, on a discuté de la possible présence d'une orientation mystique ou “illuminative” dans l'oeuvre d'Ibn Sīnā . Le sens et le contenu de son ouvrage (partiellement perdu) al-Mashriqiyyūn (Les Orientaux), également connu comme al-Ḥikma al-Mashriqiyya (La Sagesse orientale), mentionné par Ibn Sīnā lui-même et par des écrivains occidentaux comme Ibn Rushd et Ibn Ṭufayl, ont souvent été au centre de ce débat. On trouve aussi quelques références à ce qui est appelé la “philosophie orientale” d'Ibn Sīnā dans l'oeuvre du juif castillan Abner de Burgos (ca. 1270-ca. 1347) connu après sa conversion au christianisme sous le nom d'Alphonse de Valladolid. Sans avoir au préalable identifié le contenu de ces citations, on a fait l'hypothèse qu'elles auraient permis de conserver des passages, inconnus par ailleurs, de l'ouvrage perdu d'Ibn Sīnā. Cette étude porte sur les références à la “philosophie orientale” d'Ibn Sīnā dans l'oeuvre d'Abner de Burgos. Elle montre que les références d'Abner semblent avoir été essentiellement tirées d'Ibn Ṭufayl et ne renvoient donc pas aux passages perdus de l'ouvrage d'Ibn Sīnā. En conséquence elles ne peuvent servir d'argument pour confirmer la présence d'une orientation mystique ou “illuminative” dans l'oeuvre d'Ibn Sīnā. (shrink)

The Islamic philosophical, mystical, and theological sub-traditions have each made characteristic assumptions about the human person, including an incorporation of substance dualism in distinctive manners. Advances in the brain sciences of the last half century, which include a widespread acceptance of death as the end of essential brain function, require the abandonment of dualistic notions of the human person that assert an immaterial and incorporeal soul separate from a body. In this article, I trace classical Islamic notions of death and (...) the soul, the modern definition of death as "brain death," and some contemporary Islamic responses to this definition. I argue that a completely naturalistic account of human personhood in the Islamic tradition is the best and most viable alternative for the future. This corporeal monistic account of Muslim personhood as embodied consciousness incorporates the insights of pre-modern Muslim thinkers yet rehabilitates their characteristic mistakes and thus has the advantages of neuroscientific validity and modern relevance in trans-cultural ethical discourse; it also helps to alleviate organ shortages in countries with majority Muslim populations, a serious ethical impasse of recent years.
