Five Facets of the Anthropological Turn in Qur’anic Hermeneutics

Majid Daneshgar and Johanna Pink, of the University of Freiburg, invited me to participate in their online lecture series “Freiburg conversations on tafsir and transregional Islamic networks II,” and Nadja Germann, also of the University of Freiburg, served as host and gave a very helpful and thought-provoking response that will reshape the outline of my long-term project on contemporary Qur’anic hermeneutics. Questions from the audience, starting with Karen Bauer, are also pushing me to rethink my starting point: should I start with the classical and modern sources of hermeneutical ideas, or with the thinkers who appeal to those classical and modern sources, or with the ideas themselves? Should I work chronologically or thematically? Up or down the isnads of intellectual transmission and exchange? The discussion really got me thinking.

There were no slides, but the full text of the talk is available here as a pdf. Video of both the talk and Nadja’s response (but not the Q&A) is available on YouTube here.

Informative and Performative Theories of Divine Speech in Classical Islamic Legal Theory

Abstract: The Qurʾān describes God’s speech as powerful and creative: “When he decrees something he merely says to it ‘Be!’ and it is.” Just as impressively, when he desires to make an action obligatory he merely says “I oblige you to do it,” or even just “do it!” This is an example of what some modern theorists of language call performative speech, which brings about a new state of affairs rather than just conveying information about what is already the case. This essay considers the emergence of the concept of performative speech in classical Islamic legal theory, presenting the debate over whether to regard God’s speech as informative or performative as part of an ongoing argument over the nature of law, the nature of God’s speech, and the relationship between them. After a brief discussion of Muḥammad ibn Idrīs al-Shāfiʿī (d. 204/820), the essay presents the views of four contrasting thinkers of the late 4th/10th and early 5th/11th centuries: the Shāfiʿī jurist and Muʿtazilī theologian ʿAbd al-Jabbār (d. 415/1025), who treated God’s speech as a purely informative description from which human beings may deduce the details of an ontologically and epistemologically prior moral order; the Ḥanbalī Abū Yaʿlā Ibn al-Farrāʾ (d. 458/1066), who took the opposite tack, treating God’s speech as a performative speech act that brings about obligations with the immediacy of a master’s face–to–face orders to a slave; the Mālikī jurist and Ashʿarī theologian Abū Bakr al-Bāqillānī (d. 403/1013), who sought to have it both ways; and the Ḥanafī Abū Zayd al-Dabūsī (d. ca. 430/1038), who appears to have introduced the term inshāʾ into Sunni legal theory. These last two thinkers sought, in very different ways, to affirm that legal obligations are brought about by God’s speech; yet they treated the language of revelation as a source of information and indicative evidence from which human interpreters could reconstruct the law through a flexible interpretive process.

The Ethical Structure of Imām al-Ḥaramayn al-Juwaynī’s Legal Theory

My contribution to the Summer Institute for Scholars on “Sharia and Ethics” hosted by the International Institute for Islamic Thought in 2014 has now been published, along with many of the other papers from that memorable symposium, in an Open Access volume on Islamic Law and Ethics.

Imām al-Ḥaramayn al-Juwaynī’s definition of law (fiqh) as knowledge of legal values (aḥkām), his definitions of those legal values, several of his interpretive principles, and other features of his legal theory (uṣūl al-fiqh) give Islamic law the structure of an ethical system that can be characterized in limited respects as a form of moral realism, as a divine command theory, and as deontic, deontological, agent-centered, individualistic, and particularistic. Comparing his vision of the law with other types of ethical systems suggests alternative ways in which Islamic law might be envisioned and defined, and reveals some profound implications of seemingly minor points of legal theory like the definitions of technical terms. In this paper, the ethical structure of al-Juwaynī’s widely taught legal theory is contrasted with virtue ethics, constructivism, consequentialism, utilitarianism, existentialism, natural law and social contract theories, as well as patient-centered, rights-centered, and relational ethical systems. Several alternative possibilities for structuring legal theory and defining its key terms are suggested by these comparisons. The goal is to imagine what legal theory might look like if it were structured around the cultivation of virtues, the establishment of certain kinds of interpersonal relationships, or the articulation of general moral principles, rather than around the eternal consequences of particular actions for the individuals who perform them. These possibilities would require not only different definitions of key terms, but also different approaches to the interpretation of revealed texts and the construction of ethical norms. Resources for reshaping legal theory around such alternative ethical structures are identified within the discipline of uṣūl al-fiqh itself and in other Islamic disciplines. No particular reformulation of legal theory is advocated, but it is argued that imagining alternatives helps us to understand al-Juwaynī’s own legal theory. We do not fully understand the significance of the theoretical choices made by scholars of uṣūl al-fiqh until we imagine what Islamic law would look like if they had chosen differently.

Does Islamic law define Islamic ethics? Or is the law a branch of a broader ethical system? Or is it but one of several independent moral discourses, Islamic and otherwise, competing for Muslims’ allegiance? The essays in this book present a range of answers: some take fiqh as the defining framework for ethics, others insert the law into a broader ethical system, and others present it as just one among several parallel Islamic ethical discourses, or show how Islamic ethics might coexist with non-Muslim normative systems. Their answers have far-reaching implications for epistemology, for the authority of jurists and lay Muslims, for the practical moral challenges of daily life, and for relationships with non-Muslims. The book presents Muslim ethicists with a strategic contemporary choice: should they pursue a single overarching methodology for judging all ethical questions, or should they relish the rhetorical and political competition of alternative but not necessarily incompatible moral discourses?
