Abstract

Collected in this volume are ten essays on Islamic philosophy, some of which have appeared before. The topics range from historical observations on the Islamic-European transmission of ideas to detailed examinations of Arabic developments in logic. The most comprehensive discussion of the latter concerns the theory of temporal modalities as found in Avicenna, al-Qazwini al-Katibi, et al. Of much wider interest is the inquiry into the Arabic concern with the notion of "existence." The author surprises the reader here by pointing out that Al-Farabi was the first to deny that existence is an attribute; that Brentano's notion of "intentional inexistence" was anticipated by both Avicenna and Averroes; that certain teachings of al-Qazwini al-Katibi accord exactly with Russell's work concerning vacuous definite descriptions. The work as a whole provides considerable evidence for Rescher's thesis, fully articulated in the final essay, that "there is no such thing as an Arabic philosophy" but only "Greek philosophy carried forward in an Arabic-language setting." Indicative of this is the correspondence between Avicenna's formulation of the "logic of questions" and the Aristotelian table of categories. Another example is the commentary of Ibn al-Salah on Book II of Aristotle's Posterior Analytics. More familiar is the syncretistic Arabic adaptation of the doctrines of Timaeus and De Caelo; this influence is discussed at length with respect to Al Kindi's cosmology. In summation, this author's work fills a number of gaps in the continuity of logical development from the Ancient-Medieval period to that of the early Renaissance.--W. S.
