Modern thought typically opposes the authority of tradition in the name of universal reason. Postmodernism begins with the insight that the sociohistorical context of tradition and its authority is inevitable, even in modernity. Modernity can no longer take itself for granted when it recognizes itself as a tradition that is opposed to traditions. The left-wing postmodernist response to this insight is to conclude that because tradition is inevitable, irrationality is inevitable. The right-wing postmodernist response is to see traditions as the (...) home of diverse forms of rationality. This requires an understanding of the Socratic, self-critical aspect of intellectual traditions, which include both modern sciences and the great world religions. (shrink)

Al-Kindi was influenced by two Greek traditions in his attempts to explain vision, light and color. Most obviously, his works on optics are indebted to Euclid and, perhaps indirectly, to Ptolemy. But he also knew some works from the Aristotelian tradition that touch on the nature of color and vision. Al-Kindi explicitly rejects the Aristotelian account of vision in his De Aspectibus, and adopts a theory according to which we see by means of a visual ray emitted from the eye. (...) But in the same work, al-Kindi draws on Philoponus. (shrink)

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)

Al-Kindi was the first philosopher of the Islamic world. He lived in Iraq and studied in Baghdad, where he became attached to the caliphal court. In due course he would become an important figure at court: a tutor to the caliph's son, and a central figure in the translation movement of the ninth century, which rendered much of Greek philosophy, science, and medicine into Arabic. Al-Kindi's wide-ranging intellectual interests included not only philosophy but also music, astronomy, mathematics, and medicine. Through (...) deep engagement with Greek tradition al-Kindi developed original theories on key issues in the philosophy of religion, metaphysics, physical science, and ethics. He is especially known for his arguments against the world's eternity, and his innovative use of Greek ideas to explore the idea of God's unity and transcendence. Despite al-Kindi's historical and philosophical importance no book has presented a complete, in-depth look at his thought until now. In this accessible introduction to al-Kindi's works, Peter Adamson surveys what is known of his life and examines his method and his attitude towards the Greek tradition, as well as his subtle relationship with the Muslim intellectual culture of his day. Above all the book focuses on explaining and evaluating the ideas found in al-Kindi's wide-ranging philosophical corpus, including works devoted to science and mathematics. Throughout, Adamson writes in language that is both serious and engaging, academic and approachable. This book will be of interest to experts in the field, but it requires no knowledge of Greek or Arabic, and is also aimed at non-experts who are simply interested in one of the greatest of Islamic philosophers.

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.

Die ethische und politische Philosophie al-Fārābīs beruht auf einer philosophischen Anthropologie, die die Menschen als von Natur aus als ungleich betrachtet und der Natur eine fundamentale Bedeutung zuschreibt. Die Natur stattet nur wenige Menschen mit besonderen Fähigkeiten aus, sodass die Verwirklichung der höheren theoretischen, geistigen, moralischen Tugend und der praktischen Kunst nur jene betrifft, die von der Natur dafür ausersehen wurden. Die Anthropologie ist darüber hinaus auch ein wichtiges Instrument politischen Handelns. Der Herrscher muss sich kontinuierlich dem Studium der menschlichen (...) Natur widmen und die jeweiligen Eigenschaften benennen, die bestimmten Menschengruppen zugeschrieben werden. Dadurch kann er die geeigneten Mittel identifizieren, mit denen jede Gruppe zur Glückseligkeit geführt werden kann, und wählt die für jeden Fall geeigneten Argumente. Niccolò Machiavelli stützt sein gesamtes politisches Denken auf die Anthropologie. Ein zweiter Pfeiler der politischen Philosophie Machiavellis ist, wie bei al-Fārābī auch, die Religion. Beide machen sich Gedanken über die politische Dimension der Religion, ohne dass Machiavelli aber bis zur Entgeistigung der Religion gehen würde, wie es al-Fārābī gewagt hatte. Neben der Anthropologie, die ein integrales Element des politischen Denkens al-Fārābīs und Machiavellis darstellt, teilen sie sich die Auffassung von der Religion als Instrument politischen Handelns. Beide versuchten den Menschen zu zeigen, dass auf dem Gebiet des öffentlichen Lebens die Regierungskunst der Religion überlegen ist, ohne sich im Besonderen mit ihrem Wert an sich und ihrer Bedeutung für das private Leben zu befassen. Der substantielle Unterschied zwischen beiden liegt in der Breite der politischen Mittel. Hier ist die Innovation Machiavellis offensichtlich, weil sich seine Anthropologie von der al-Fārābīs unterscheidet. (shrink)
