Arabic contributions to medicine, mathematics, astronomy, and other fields have been extensively studied, yet Arabic logic has never been systematically investigated. In this book, Nicholas Rescher sheds new light on the major philosophical contribution of Arab logicians. He provides a historical account of the evolution of Arabic logic, from its inception in the early ninth century through the sixteenth century, when these tenets gained wide acceptance. The book also includes a bio-bibliography of 170 Arabic logicians, and a discussion of the place of each within the overall scheme of developments

Our cognitive competence is well accounted for by our evolutionary niche in the world's scheme of things. The development of inquiry in natural science is best understood on analogy with exploration -- to be sure, not in the geographical mode but rather exploration in nature's parametric space of such physical quantities as temperature, pressure, and field strength. The technology-mediated exploration at issue here involves an interaction between us humans and nature that becomes increasingly difficult as we move ever farther away from the home base of the accustomed environment of our evolutionary heritage. The course of scientific progress accordingly involves a technological escalation -- an ascent to successively higher levels of technological sophistication that is unavoidably required for the production of the requisite observational data

The greatest of the Arabic philosophers was the Spanish Muslim Abu-l-Walid Muhammad ibn Ahmad ibn Muhammad ibn Rushd = Averroes. In the midst of a busy public career, as court scholar and personal physician to an Almohad caliph, and as chief magistrate of Cordova, Ibn Rushd found time to compose a monumental series of philosophical commentaries, as well as several important legal, astronomical, and medical works. His extensive commentaries on Aristotle earned him St. Thomas's accolade of "The Commentator."

SUPPORTERS of a coherentist standard of truth must be able to establish that this criterion is duly consonant with the definitional nature of truth, for there ought rightfully to be a continuity between our evidential criterion of acceptability-as-true and the "truth" as definitionally specified. Any satisfactory criterion must be such as to yield the real thing--at any rate in sufficiently favorable circumstances. Fortunately for coherentism, it is possible to demonstrate rigorously that truth is tantamount to ideal coherence--that a proposition's being true is in fact equivalent with its being optimally coherent with an ideal data base. Given that the preceding continuity requirement is satisfied, the traditional view of truth as accord with fact is thus also available to coherentists. However, the element of idealization at issue means that we cannot claim that coherence provides us with unqualified truth in actual practice. The coherence-based inquiries we actually carry out, can go only so far as to afford our best available estimate of the real truth.

In one form or another the concept of the Absolute has played a prominent role in Western philosophy from Plato to Hegel and beyond. The present paper addresses in particular the idea of the Absolute as the completion or perfection of the cognitive project of inquiry into the nature of the real. The discussion first traces the historical development of this conception, and then addresses the question of what sort of constructive role such a concept of cognitive absoluteness can continue to play in philosophical deliberation, arguing that it does indeed afford an instrumentality able to accomplish useful work.
