Abstract
Ali Sadad Bey is the first traditional logician in the Islamic world to have had a scholarly encounter with mathematical modern logic. He authored "Mizan al-Uqol, fi al-mantik va al-ousol"an Ottoman Turkish textbook on comparative logic. In this book, he first briefly presents the contents of traditional logic, secondly introduces and criticizes the new teachings of English logicians George Boole, William Hamilton, and DeMorgan, and thirdly includes discussions on the foundations and methodology of science.Sedad believed logical studies in the Islamic world had progressed beyond those in Europe, attributing skepticism in Western philosophy to backwardness in logical studies.He aimed to illuminate the historical roots of this perceived deficiency and to demonstrate the superiority of Avicennan logic compared to its European counterparts.Mizan al-Uqol is regarded as a turning point in the history of logic in Türkiye, both setting trends and generating a range of positive and negative reactions within the Turkish intellectual community.
