An integrative approach to Jewish and Muslim philosophy in al-Andalus Al-Andalus, the Iberian territory ruled by Islam from the eighth to the fifteenth centuries, was home to a flourishing philosophical culture among Muslims and the Jews who lived in their midst. Andalusians spoke proudly of the region's excellence, and indeed it engendered celebrated thinkers such as Maimonides and Averroes. Sarah Stroumsa offers an integrative new approach to Jewish and Muslim philosophy in al-Andalus, where the cultural commonality of the Islamicate world allowed scholars from diverse religious backgrounds to engage in the same philosophical pursuits. Stroumsa traces the development of philosophy in Muslim Iberia from its introduction to the region to the diverse forms it took over time, from Aristotelianism and Neoplatonism to rational theology and mystical philosophy. She sheds light on the way the politics of the day, including the struggles with the Christians to the north of the peninsula and the Fa t imids in North Africa, influenced philosophy in al-Andalus yet affected its development among the two religious communities in different ways. While acknowledging the dissimilar social status of Muslims and members of the religious minorities, Andalus and Sefarad highlights the common ground that united philosophers, providing new perspective on the development of philosophy in Islamic Spain.

While the great medieval philosopher, theologian, and physician Maimonides is acknowledged as a leading Jewish thinker, his intellectual contacts with his surrounding world are often described as related primarily to Islamic philosophy. "Maimonides in His World" challenges this view by revealing him to have wholeheartedly lived, breathed, and espoused the rich Mediterranean culture of his time.

Sarah Stroumsa argues that Maimonides is most accurately viewed as a Mediterranean thinker who consistently interpreted his own Jewish tradition in contemporary multicultural terms. Maimonides spent his entire life in the Mediterranean region, and the religious and philosophical traditions that fed his thought were those of the wider world in which he lived. Stroumsa demonstrates that he was deeply influenced not only by Islamic philosophy but by Islamic culture as a whole, evidence of which she finds in his philosophy as well as his correspondence and legal and scientific writings. She begins with a concise biography of Maimonides, then carefully examines key aspects of his thought, including his approach to religion and the complex world of theology and religious ideas he encountered among Jews, Christians, Muslims, and even heretics; his views about science; the immense and unacknowledged impact of the Almohads on his thought; and his vision of human perfection.

This insightful cultural biography restores Maimonides to his rightful place among medieval philosophers and affirms his central relevance to the study of medieval Islam.

The literary works of ninth-century scholar Dawud al-Muqammas, who converted from Judaism to Christianity and then back to Judaism, reflect his pioneering approaches during a formative time in Jewish and Muslim medieval philosophy. A master of diverse genres, he composed in the ninth century, among other works, the thoughtful Twenty Chapters, which is not only the first known Jewish Kalam text, but also the earliest extant theological summa written in Arabic. This authoritative edition includes the full Judeo-Arabic text in Arabic letter transcription with a facing English translation, as well as an introduction, notes, bibliography, and index.

Sarah Stroumsa untersucht die als "Convivencia" bezeichnete interkommunale Balance zwischen christlichen, jüdischen und muslimischen Gemeinschaften im mittelalterlichen islamischen Osten. Sie zeigt auf, dass gerade das Vermächtnis der christlichen Akademien in der Spätantike einen tragfähigen Rahmen für das Betreiben von Philosophie bot, dem sich sowohl Juden als auch Muslime anschließen konnten. Guy G. Stroumsa nimmt die Erforschung von Judentum und Islam in der europäischen Wissenschaft des 19. Jahrhunderts in den Blick. Anhand zahlreicher Beispiele zeigt er auf, wie sich in der Geschichte der einschlägigen wissenschaftlichen Disziplinen durchweg breitere kulturelle Trends und gesellschaftliche Entwicklungen widerspiegeln.
