This article is about the conception of truth and signification in Augustine's early philosophical writings. In the first, semantic-linguistic part, the gradual shift of Augustine's position towards the Academics is treated closely. It reveals that Augustine develops a notion of sign which, by integrating elements of Stoic epistemology, is suited to function as a transmitter of true knowledge through linguistic expressions. In the second part, both the ontological structure of signified (sensible) things and Augustine's solution to the apparent tautologies of (...) mathematical truths are examined. Again his notion of sign turns out to be the keystone; this time, however, the natural in contrast to the conventional sign of linguistic expressions. In their complementarity, both parts show how Augustine intensely struggles with and (partially) overcomes the skepticism of the sensible world through his conception of sign and signification.

Divisions of the sciences have been popular objects of study ever since antiquity. One reason for this esteem might be their potential to reveal in a succinct manner how scholars, schools or entire societies thought about the body of knowledge available at their time and its specific structure. However, what do classifications tell us about the pleasures of knowledge? Occasionally, quite a lot, particularly in a setting where the acquisition of knowledge is considered to be the only path leading to (...) the pleasures of ultimate happiness. This is the case for al-Fārābī, who is at the center of this paper. He is particularly interesting for a study such as this because he actually does believe that humanity’s final goal consists in the attainment of happiness through the acquisition of knowledge; and he wrote several treatises, not only on the classification of the sciences as such, but also on the underlying epistemological reasons for this division. Thus he offers excellent insight into a 10th-centu... (shrink)

This article is focused on the concept of logic in Avicenna’s Isagoge, a text which had great impact both on Arabic and Western thought. Its main section is devoted to an investigation of Avicenna’s clarification of the nature of logic, its proper subject matter as well as its place within the canon of the philosophical sciences. In this connection, special attention is given to Avicenna’s use of the concepts ‘art’ and ‘science’. Significantly, he regards logic as both a science and (...) an art, and argues that in the latter sense, logic is an instrument for the philosophical sciences. Because Avicenna’s Isagoge was read in the Latin West for several centuries, his ideas on the nature of logic played a prominent role in the debates at medieval universities and hence were a likely source of the distinction between ‘logica utens’ and ‘logica docens’.

What is language? How did it originate and how does it work? What is its relation to thought and, beyond thought, to reality? Questions like these have been at the center of lively debate ever since the rise of scholarly activities in the Islamic world during the 8th/9th century. However, in contrast to contemporary philosophy, they were not tackled by scholars adhering to only one specific discipline. Rather, they were addressed across multiple fields and domains, no less by linguists, legal (...) theorists, and theologians than by Aristotelian philosophers. In response to the different challenges faced by these disciplines, highly sophisticated and more specialized areas emerged, comparable to what nowadays would be referred to as semantics, pragmatics, and hermeneutics, to name but a few – fields of research that are pursued to this day and still flourish in some of the traditional schools. Philosophy of language, thus, has been a major theme throughout Islamic intellectual culture in general; a theme which, probably due to its trans-disciplinary nature, has largely been neglected by modern research. This book brings together for the first time experts from the various fields involved, in order to explore the riches of this tradition and make them accessible to a broader public interested both in philosophy and the history of ideas more generally.

This article focuses on the notion of philosophy in Ibn Ṭufayl’s Ḥayy ibn Yaqẓān. In the prologue to his work, Ibn Ṭufayl promises to reveal the «secrets» of Avicenna’s Eastern Philosophy — a book already lost at that time and only referred to by Avicenna in his Book of the Healing. Since Ibn Ṭufayl identifies these «secrets» with the «truth» he himself has attained, and contrasts them with the views of the philosophers of his day, the question arises as to (...) what concept of philosophy he supports. The article will argue that he generally agrees with the prevailing philosophical curriculum of his time. Moreover, he subscribes to the traditional conviction that man strives for the good, and that this good must be sought in noetic perfection. As will become clear, however, Ibn Ṭufayl amplifies these common notions by integrating into them a peculiar concept of immediate vision of God and its concomitant, namely enjoyment. Therefore, in contrast to his most important predecessors, al-Fārābī and Avicenna, for Ibn Ṭufayl philosophy has an unambiguously practical character, as it places great practical demands upon humans for the achievement of perfect knowledge.

Les architectures médiévales du savoir conçues dans le monde islamique, constituent un cas particulier : elles reflètent parfaitement la compétition entre les différentes traditions et approches intellectuelles. D’une part, certaines des classifications sont centrées sur ce qui était perçu comme sciences indigènes durant leur période de formation, c’est-à-dire ces sciences qui émergent en connexion avec la nouvelle religion qu’est l’Islam et la langue de sa révélation, l’arabe. D’autre part, les savants ont repris avec empressement et adapté les disciplines dérivant de (...) cultures non-arabes et non-musulmanes, principalement la science et la philosophie grecques. Cependant, ces traditions transmettent leurs propres conceptions de la connaissance, en partie en conflit avec les idées arabes/islamiques. Dans cet article, je propose un aperçu des approches diverses puis me concentre sur Fārābī et Avicenne, afin de retracer un développement remarquable : la dissolution graduelle des frontières aussi bien au sein qu’entre les différentes sphères et paradigmes scientifiques et ce sur des bases épistémologiques.

This study, regarding the problems surrounding 'time' during the 9th to 11th centuries, offers new insights into the scientific interests and rationality of the quadrivium, and argues for the existence of a 'discovery of nature' prior to the 12th century.
