Canada Research Chair in the History of Science in Islamic Societies

My graduate training was as a historian of science (Harvard, PhD, 1982), but I have had strong interests in Middle Eastern and Islamic Studies since my days as an undergraduate (BA, Anthropology of the Middle East, 1972; MA, Near Eastern Studies, 1973; both at the University Michigan). After a number of post-docs and short-term teaching positions, I was a professor in the Department of the History of Science at the University of Oklahoma from 1990 until 2006, at which time I moved to the Institute of Islamic Studies at McGill where I have held a Canada Research Chair since 2007. Before coming to McGill, my main teaching was in the history of science; in recent years I have focused more on science in premodern Islam and the interactions of science and religion. This has run parallel to my increasing research interest in broader questions of Islamic intellectual history, which have been stimulated and advanced by my colleagues and visiting researchers here at the Institute.


My research program aims to transform the conventional view of pre-1800 Islamic intellectual history by providing concrete and verifiable evidence that a nonreligious cosmology was integrated into the worldview of a substantial number of Muslim intellectuals and educated laypeople, and that this worldview found a place within both religious and secular institutions. Another aspect of this research is tracing the transmission of scientific objects, ideas, and ideals between various cultural regions in the premodern period. An outcome of this latter investigation  has challenged our understanding of early modern European science by showing that a number of its salient features usually taken to prove European exceptionalism had, in fact, Islamic roots.

To accomplish this research, my students and I engage in the close study of texts, the examination of scientific objects, and the use of a sophisticated database with which to analyze information gathered from those close readings and examinations.

At present, these are the main areas of our research interests:

1. The Rise and Development of hayʾa (theoretical astronomy)
The hayʾa astronomical genre allowed Islamic astronomers to provide a picture of the universe, a kind of scientific cosmology, based upon the mathematical models developed from observations of the various celestial motions but also including information on the sublunar realm (i.e. the Earth’s geography and its atmosphere). The roots of this genre lie in Greek antiquity, but it was pursued with increased vigor among Islamic scholars. A good deal of my research has focused on this genre, in terms of its importance as a venue for criticisms of Ptolemaic astronomy but also as an indication of a “scientific cosmology” that became widespread throughout Islamic lands. Thus a prime focus of our future research will be to study the genre as a whole (consisting of at least 100 titles produced over a millennium), aided by our database, and pay particular attention to selected texts that I will edit and translate. A new departure will be studying the as yet untapped geographical information contained in these texts, which is the subject of the PhD research of one of our students.

2. Criticism of Ptolemy and the Proposal of Alternative Models
Up to now, the main interest in hayʾa texts has been in those in which authors proposed new models. These alternative models were meant to replace those of Ptolemy in which there were violations of the rule that all celestial motion should be uniform and circular. Again one of the main motivations for this research has been the similarity of these models with those of Copernicus. What is needed is a comprehensive understanding of these models and their motivations as well as the reasons for their proliferation from one astronomer to another. Why were earlier models considered inadequate? Why did some authors allow for certain types of devices (e.g. epicycles and eccentrics) while others disallowed one or another? This comprehensive survey will be critical in understanding this important tradition of criticism and reform in Islamic astronomy and its subsequent adoption by European astronomers such as Copernicus.

3. Motivations and Infrastructure for Precise Observation
One of the interesting and puzzling aspects of early Islamic astronomy is the emphasis on careful and precise observation, something that marks it as significantly different than earlier Greek observations. I have argued that this can be connected to Islamic religious doctrines, in particular the imperative to learn about God’s “created world” and several of my students are expanding this research by looking at religious literature (theological works and commentaries on the Qurʾān) to find more evidence. Several students are also doing research on astronomical instruments and observations and how these latter came to be incorporated into handbooks called zījes.

4. Separation of Mathematical Astronomy from Philosophical Cosmology
I have claimed in various publications that mathematical astronomy in Islam, and in particular hayʾa, came more and more to be conceived as independent of Aristotelian natural philosophy. This has usually been seen as a hallmark of European exceptionalism, but recent work has shown that religious considerations among several Islamic scientists were at work in their separation of astronomy and the other mathematical sciences from philosophy. This has important implications for the way we conceive of the development of modern science and its philosophical underpinnings. This research will proceed in several ways. Students working under my supervision are examining astronomical passages in a Qurʾān commentary, another is studying the work of al-Sayyid al-Sharīf al-Jurjānī, and Robert Wisnovsky and I will conduct (in Winter 2015) a seminar on ʿAlī Qushjī’s fifteenth-century theological treatise.

5. Integration of Scientific Cosmology within Cultural/Religious Institutions of Islamic Societies
This will be in conjunction with our Islamic Scientific Manuscripts Initiative and the post-doctoral work of Sally Ragep, who is a senior researcher at McGill. Contrary to the
standard narrative, we are finding many examples in manuscripts and other sources that theoretical astronomy was taught in religious institutions (madrasas). Because of the vast numbers of manuscript witnesses we have catalogued, and their widespread dissemination, we are in a position to use quantitative data to show that the scientific cosmology inherent in hayʾa texts had become the standard cosmology taught in religious schools. This surprising and counter-intuitive conclusion will need to be properly presented and documented, so in the next phase of the project we plan to use query and presentation tools developed here at McGill in cooperation with our partners at the Max Planck Institute for the History of Science in Berlin to buttress our claims in preparation for publication.

6. Transmission to Europe, South Asia and East Asia
In addition to studying hayʾa as a part of Islamic scientific history, another part of the project has been to deal with its transmission to other cultural areas. Obviously the connection to
Copernicus has been a major part of this research, and I am now completing a book project (sponsored by the Max Planck Institute for the History of Science in Berlin) on the multicultural background to the Copernican Revolution that has discovered new transmission routes through Byzantium and Jewish intermediaries. In addition to transmission to Europe, intercultural scientific exchanges occurred between Islam and South and East Asia, and we plan to collaborate with various partners to examine these exchanges more closely.
