Aristotle is oftentimes viewed through a strictly philosophical lens as heir to Plato and has having introduced logical rigor where an emphasis on the theory of Forms formerly prevailed. It must be appreciated that Aristotle was the son of a physician, and that his inculcation of the thought of other Greek philosophers addressing health and the natural elements led to an extremely broad set of biologically- and medically-related writings. As this article proposes, Aristotle deepened the fourfold theory of the elements (...) with anatomic and physiologic observations. In books like History of Animals, Parts of Animals, and the lost Anatomai, he actively dissected organisms and recorded his findings. The corpus of medically-related literature Aristotle developed had a direct influence on subsequent Greek thinkers, including Galen, and on Medieval Islamic and modern Western practitioners such as William Harvey. Aristotle's ideas continue to influence modern medical thinkers in Europe and America through both his interpretation by European philosophers gaining the attention of medical humanists, and his writings' enduring impact on medical researchers balancing scientific with more personalistic approaches to medicine.

"The debate recorded in al-Ghazālī's Incoherence of the Philosophers, and Ibn Rushd's response in Incoherence of the Incoherence, is one of the most philosophically interesting events in the history of classical Islamic thought. Here, the cutting edge of Ghazālī's searching critique meets the depth of Ibn Rushd's philosophical insight in a clash over the innovative synthesis of Aristotelian and Neo-Platonic thought represented chiefly by Ibn Sīnā. This critical commentary closely analyses and evaluates the arguments deployed by all three parties in (...) the debate, wherein are raised questions about the origin of the universe and the reality of time, possibility, causality, and nature. Where opportunities arise, it actively engages in the discussion by suggesting alternative arguments and philosophical directions. It goes beyond the cliché construal of the Incoherence debate as simply a conflict between faith and reason, exposing it as a genuinely philosophical enterprise and a potential source of fresh perspectives on contemporary discussions in metaphysics and analytic theology"--.

An experiment, in the standard scientific sense of the term, is a procedure in which some object of study is subjected to interventions that aim at obtaining a predictable outcome or at least predictable aspects of the outcome. The distinction between an experiment and a non-experimental observation is important since they are tailored to different epistemic needs. Experimentation has its origin in pre-scientific technological experiments that were undertaken in order to find the best technological means to achieve chosen ends. Important (...) parts of the methodological arsenal of modern experimental science can be traced back to this pre-scientific, technological tradition. It is claimed that experimentation involves a unique combination of acting and observing, a combination whose unique epistemological properties have not yet been fully clarified. (shrink)

This article explores the essence of the human (insān) as it is understood in Twelver Shīʿī philosophy and mysticism. It presents a Shīʿī philosophical elucidation regarding the possible existence of extraterrestrial intelligent lifeforms and what their relationship with “humanhood” might be. This line of reasoning is presented with a general sketch of how, in Shīʿī Islamic thought, a “human being” is characterized by specific traits and the relationship of human beings with the archetype of the Perfect Human (al‐Insān al‐Kāmil). Following (...) this is a review of Shīʿī Imāmī traditions regarding extraterrestrial intelligent life and the plurality of worlds. This sequence ultimately allows for a unique analysis of humanhood according to the Shīʿī philosophical viewpoint and helps determine if the term “human” can be used for other intelligent beings with similar ontological features and intelligence levels.

Avicenna's notorious claim that God knows particulars only 'in a universal way' is argued to have its roots in Aristotelian epistemology, and especially in the "Posterior Analytics". According to Avicenna and Aristotle as understood by Avicenna, there is in fact no such thing as 'knowledge' of particulars, at least not as such. Rather, a particular can only be known by subsuming it under a universal. Thus Avicenna turns out to be committed to a much more surprising epistemological thesis: even humans (...) know particulars only in a universal way. (shrink)

The theistic doctrine of creation highlights the significance of the world's dependence on God. For this doctrine, a variety of justifications have been offered based on the ontological and epistemological commitments of a philosopher or theologian. In this dissertation, I defend the thesis that the theistic doctrine of creation is strongly justified when on the one hand the integrity of nature is established by affirming causal necessity while on the other hand the sovereignty of God is maintained by affirming divine (...) simplicity, eternity, and immutability. To construct my argument, in the first chapter, I examine the Aristotelian roots of causal necessity and its development by Avicenna. I also consider objections to causal necessity raised by Hume and al-Ghazālī and some contemporary objections by David Lewis. In the second chapter, I identify three competing theses to explain the integrity of nature, namely, the regularism, the extrinsic necessitarianism, and the intrinsic necessitarianism. I conclude that the intrinsic necessitarianism is the strongest among them. In the third chapter, I make a case for the sovereignty of God by exploring the limits of the concept of the theistic God and claim that sovereignty is conditional on immutability, simplicity, and eternity, which qualify the divine attributes of knowledge, power, and goodness. In the last chapter, after analyzing strengths and weaknesses of theistic accounts of creation, I propose an account of ontological dependence by extending Avicenna's account of creation, which consists in God's conferral of existence, to His sustaining activity at all times during which an object endures.

A revisionist account of how philosophical induction was conceived in the ancient world and how that conception was transmitted, altered, and then rediscovered. I show how philosophers of late antiquity and then the medieval period came step-by-step to seriously misunderstand Aristotle’s view of induction and how that mistake was reversed by humanists in the Renaissance and then especially by Francis Bacon. I show, naturally enough then, that in early modern science, Baconians were Aristotelians and Aristotelians were Baconians.

Do the senses represent causation? Many commentators read Nicolas Malebranche as anticipating David Hume’s negative answer to this question. I disagree with this assessment. When a yellow billiard ball strikes a red billiard ball, Malebranche holds that we see the yellow ball as causing the red ball to move. Given Malebranche’s occasionalism, he insists that the visual experience of causal interaction is illusory. Nevertheless, Malebranche holds that the senses represent finite things as causally efficacious. This experience of creaturely causality explains (...) why Aristotelian philosophers and others struggle to recognize occasionalism’s truth. (shrink)

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.

The 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 staunch rationalism and an emerging empiricism.

There is a disagreement among contemporary commentators about Avicena's view of the theoretical intellect in "Kitāb alnafs". Is its activity performed by an internal sense helped by the intellect, or is it a activity proper of the intellect independently of material forms? Some passages of V.5 and V.6 suggest that both elements are necessary to the knowledge: unifying the multiplicity and multiplying the unity; in others words, it is not enough that the intellect conceptualizes the minor and major terms of (...) the syllogism, it also needs to intuit the middle term.

This dissertation offers a new and comprehensive analysis of Abū Naṣr al-Fārābī's cosmology by focusing on various important issues that have been largely neglected by the modern scholarship. It provides an examination of the physical, metaphysical, and astronomical aspects of al-Fārābī's cosmology by adopting a multidisciplinary approach that takes into account the history of philosophy and the history of astronomy. Accordingly, my dissertation explores how al-Fārābī attempted to reconcile features of Ptolemaic astronomy with Aristotelian and Neoplatonic theories, an endeavor which (...) resulted in the formulation of innovative cosmological ideas. Chapters I and II provide background information on al-Fārābī's activity as a commentator and his relation to the Greek commentatorial tradition and assess the relevant primary sources. In addition, they examine al-Fārābī's approach to cosmology and his scientific method in terms of both the Ptolemaic astronomical tradition and the Aristotelian corpus. Chapter III addresses problems related to the structure of al-Fārābī's cosmology, especially the origin of his ennadic cosmological model and his spherology. Particular attention is devoted to the question of how Aristotle's unmoved movers and Ptolemy's astronomical theories are reconciled. Chapters IV, V, and VI analyze the place of celestial matter, intellect, and motion respectively in al-Fārābī's cosmology and attempt to redefine the second teacher's relation to the various trends of Greek philosophy. The study stresses al-Fārābī's connection with the Neoplatonic and Peripatetic currents, particularly with thinkers such as Alexander of Aphrod. (shrink)
