Inferences by Parallel Reasoning in Islamic Jurisprudence

This monograph proposes a new (dialogical) way of studying the different forms ofcorrelational inference, known in the Islamic jurisprudence asqiy?s. According to the authors' view,qiy?srepresents an innovative and sophisticated form of dialectical reasoning that not only provides new epistemological insights into legal argumentation in general (including legal reasoning in Common and Civil Law) but also furnishes a fine-grained pattern forparallel reasoningwhich can be deployedin a wide range of problem-solving contextsand does not seem to reduce to the standard forms of analogical reasoning studied in contemporary philosophy of science and argumentation theory. After an overview of the emergence ofqiy?sand of the work of al-Sh?r?z? penned by Soufi Youcef, the authors discuss al-Sh?r?z?'s classification of correlational inferences of the occasioning factor (qiy?s al-'illa). The second part of the volume deliberates on the system of correlational inferences by indication and resemblance (qiy?s al-dal?la, qiy?s al-shabah). The third part develops the main theoretical background of the authors' work, namely,the dialogical approach to Martin-Löf's Constructive Type Theory. The authors present this in a general form andindependently of adaptationsdeployed in parts I and II. Part III also includes an appendix on the relevant notions of Constructive Type Theory, which has been extracted from an overview written by Ansten Klev. The book concludes with some brief remarks on contemporary approaches to analogy in Common and Civil Law and also to parallel reasoning in general.
