A debated topic in Avicennan psychology is whether for Avicenna abstraction is a metaphor for emanation or to be taken literally. This issue stems from the deeper philosophical question of whether humans acquire intelligibles externally from an emanation by the Active Intellect, which is a separate substance, or internally from an inherently human cognitive process, which prepares us for an emanation from the Active Intellect. I argue that the tension between thesedoctrines is only apparent. In his logical works Avicenna limns (...) an account where through the internal human process of abstraction accidents accruing to an essence existing in matter are extracted, thus preparing the essence for new accidents emanating externally from the Active Intellect, which make the essence something conceptualized in the intellect. This study, then, outlines the epistemological and metaphysical framework presented in the logical works that underpins Avicenna’s theory of abstraction presented in his psychological works.

The paper treats Avicenna’s ’metaphysical’ argument for the existence of God and the modal metaphysics that underpins it. Earlier analyses of modalities attempted to reduce necessity, possibility and impossibility to nonmodal elements, which was done most commonly by appealing to a temporal frequency model of modalities. In contrast, Avicenna believed that modalities were an inherent feature of existence, and so just as there is nothing more basic than existence, so likewise there is nothing more basic in term of which modalities (...) can be explained. The article concludes by considering how Avicenna’s modal metaphysics in turn provides him the means to show the absolute and nonconditional necessity of God, as opposed to the conditional necessity of earlier ’physical’ arguments.

This book is designed to remedy that lack.

Aristotle's account of place in terms of an innermost limit of a containing body was to generate serious discussion and controversy among Aristotle's later commentators, especially when it was applied to the cosmos as a whole. The problem was that since there is nothing outside of the cosmos that could contain it, the cosmos apparently could not have a place according to Aristotle's definition; however, if the cosmos does not have a place, then it is not clear that it could (...) move, but it was thought to move, namely, in its daily revolution, which was viewed as a kind of natural locomotion and so required the cosmos to have a place. The study briefly outlines Aristotle's account of place and then considers its fate, particularly with respect to the cosmos and its motion, at the hands of later commentators. To this end, it begins with Theophrastus' puzzles concerning Aristotle's account of place, and how later Greek commentators, such as Alexander of Aphrodisias, Themistius and others, attempted to address these problems in what can only be described as ad hoc ways. It then considers Philoponus' exploitation of these problems as a means to replace Aristotle's account of place with his own account of place understood in terms of extension. The study concludes with the Arabic Neoplatonizing Aristotelian Avicenna and his novel introduction of a new category of motion, namely, motion in the category of position. Briefly, Avicenna denies that the cosmos has a place, and so claims that it moves not with respect to place, but with respect to position. (shrink)

: The present study considers Ibn Sînâ's (Lat. Avicenna) account of induction (istiqra') and experimentation (tajriba). For Ibn Sînâ induction purportedly provided the absolute, necessary and certain first principles of a science. Ibn Sînâ criticized induction, arguing that it can neither guarantee the necessity nor provide the primitiveness required of first principles. In it place, Ibn Sînâ developed a theory of experimentation, which avoids the pitfalls of induction by not providing absolute, but conditional, necessary and certain first principles. The theory (...) of experimentation that emerges though not modern, does have elements that are similar to a modern conception of scientific method. (shrink)
