Philosophy and jurisprudence in the Islamic world This book brings together the study of two great disciplines of the Islamic world: law and philosophy. In both sunni and shiite Islam it became the norm for scholars to acquire a high level of expertise in the legal tradition. Thus some of the greatest names in the history of Aristotelianism were trained jurists like Averroes or commented on the status and nature of law like al Fārābī. While such authors sought to put law in its place relative to the philosophical disciplines others criticized philosophy from a legal viewpoint like al Ghazālī and Ibn Taymiyya. But this collection of papers does not only explore the relative standing of law and philosophy. It also looks at how philosophers theologians and jurists answered philosophical questions that arise from jurisprudence itself. What is the logical structure of a well formed legal argument What standard of certainty needs to be attained in passing down judgments and how is that standard reached What are the sources of valid legal judgment and what makes these sources authoritative May a believer be excused on grounds of ignorance Together the contributions provide an unprecedented demonstration of the close connections between philosophy and law in Islamic society while also highlighting the philosophical interest of texts normally studied only by legal historians.
