First paragraph: The first international symposium on Ibn Ḥazm ever convened, to the best of our knowledge, was held in Spain in 1963 with twenty-five participants. The second such symposium was hosted by the Faculty of Theology, Uludağ University and the Muftiship of Bursa on 26-28 October 2007, in Bursa, Turkey. At the latter symposium, which comprised five sessions, twenty-eight papers and eighteen discourses were presented. The proceedings were published in book form after a delay of three years. Three of the contributions were in English, one was in Arabic, and others were in Turkish. The contributions that were not written in Turkish were published in their original language with a Turkish translation. The work is the fruit of a meticulous editorship and promises to become a significant reference work on Ibn Ḥazm. The proceedings are introduced under the headings of philosophy, kalām, fiqh (Islamic jurisprudence), the history of religions, and other fields.
