A comprehensive study of Muslim thinker al-Ghazali's life and his understanding of cosmology-how God creates things and events in the world, how human acts relate to God's power, and how the universe is structured.

It has been customary to see the Muslim theologian Abu Hamid al-Ghazali (d. 1111) as a vehement critic of philosophy, who rejected it in favour of Islamic mysticism (Sufism), a view which has come under increased scrutiny in recent years. This book argues that al-Ghazali was, instead, one of the greatest popularisers of philosophy in medieval Islam. The author supplies new evidence showing that al-Ghazali was indebted to philosophy in his theory of mystical cognition and his eschatology, and that, moreover, in these two areas he accepted even those philosophical teachings which he ostensibly criticized. Through careful translation into English and detailed discussion of more than 80 key passages (with many more surveyed throughout the book), the author shows how al-Ghazali’s understanding of "mystical cognition" is patterned after the philosophyof Avicenna (d. 1037). Arguing that despite overt criticism, al-Ghazali never rejected Avicennian philosophy and that his mysticism itself is grounded in Avicenna’s teachings, the book offers a clear and systematic presentation of al-Ghazali’s "philosophical mysticism." Challenging popular assumptions about one of the greatest Muslim theologians of all time, this is an important reference for scholars and laymen interested in Islamic theology and in the relations between philosophy and mysticism.

Al-Ghazālī (d. 505/1111) is one of the most influential thinkers of Islam. There is hardly a genre of Islamic literature where he is not regarded as a major authority. Islamic Law, Sufism, ethics, philosophy, and theology are all deeply shaped by him. Yet in the past thirty years, the field of Ghazālī-studies has been shaken by the realization that Avicenna (Ibn Sīnā, d. 428/1037) and other philosophers had a strong influence on him. Now, after the 900th anniversary at his death, the field emerges stronger than ever. This second volume of Islam and Rationality: The Impact of al-Ghazālī brings together twelve leading experts on al-Ghazālī who write about his thought and the impact it had on later Muslim thinkers. Contributors are: Anna Ayşe Akasoy, Ahmed El Shamsy, Kenneth Garden, Frank Griffel, Jules Janssens, Damien Janos, Taneli Kukkonen, Stephen Ogden, M. Sait Özervarlı, Martin Riexinger, Ulrich Rudolph, and Ayman Shihadeh.

In recent decades, scholars have come to recognize the importance of classical Islamic philosophy both in its own right and in its preservation of and engagement with Western philosophical ideas. At the same time, the period immediately following the so-called classical period has often beenseen as a sort of dark age, in which Islamic thought entered a long period of decline. In this monumental new work, Frank Griffel seeks to overturn this conventional wisdom, arguing that what he calls the "post-classical" period has been unjustly maligned and neglected by previous generations ofscholars.The Formation of Post-Classical Philosophy in Islam is a comprehensive study of the far-reaching changes that led to a re-shaping of the philosophical discourse in Islam during the twelfth century. Earlier Western scholars thought that Islam's engagement with the tradition of Greek philosophy endedduring that century. More recent analyses suggest that Islamic thinkers instead integrated Greek thought into the genre of rationalist Muslim theology (kalam). Griffel argues that even this view misses a key point. In addition to the integration of Greek ideas into kalam, Muslim theologians pickedup the discourse of philosophy in Islam (falsafa) and began to produce books on philosophy. Books in these two genres, kalam and philosophy, argue for opposing teachings on the nature of God, the world's creation, and on the afterlife - even when written by the same authors. Griffel explains theemergence of a new genre of philosophical books called "hikma," works that stand opposed to Islamic theology and at the same wish to complement it. Offering a detailed history of philosophy in Iraq, Iran, and Central Asia during the twelfth century, together with an analysis of the way philosophywas practiced during this time, Griffel shows how works of falsafa, written by major Muslim theologians such as al-Ghazali developed step-by-step into critical assessments of philosophy that try to improve philosophical teachings, and eventually become fully fledged philosophical summas in the workof Fakhr al-Din al-Razi. Griffel's examination of the different methods of kalam and hikma demonstrate both the coherence and ambiguity of a Muslim post-classical philosopher's oeuvre.A work of extraordinary breadth and depth, The Formation of Post-Classical Philosophy in Islam will be essential reading for anyone interested in the history of Philosophy or the history of Islam.

Centuries after his death, al-Ghazali remains one of the most influential figures of the Islamic intellectual tradition. Although he is best known for his Incoherence of the Philosophers, Moderation in Belief is his most profound work of philosophical theology. In it, he offers what scholars consider to be the best defense of the Ash'arite school of Islamic theology that gained acceptance within orthodox Sunni theology in the twelfth century, though he also diverges from Ash'arism with his more rationalist approach to the Quran. Together with The Incoherence of the Philosophers, Moderation in Belief informs many subsequent theological debates, and its influence extends beyond the Islamic tradition, informing broader questions within Western philosophical and theological thought. The first complete English-language edition of Moderation in Belief, this new annotated translation by Aladdin M. Yaqub draws on the most esteemed critical editions of the Arabic texts and offers detailed commentary that analyzes and reconstructs the arguments found in the work’s four treatises. Explanations of the historical and intellectual background of the texts also enable readers with a limited knowledge of classical Arabic to fully explore al-Ghazali and this foundational text for the first time. With the recent resurgence of interest in Islamic philosophy and the conflict between philosophy and religion, this new translation will be a welcome addition to the scholarship.

The Muslim thinker al-Ghazali (d. 1111) was one of the most influential theologians and philosophers of Islam and has been considered an authority in both Western and Islamic philosophical traditions. Born in northeastern Iran, he held the most prestigious academic post in Islamic theology in Baghdad, only to renounce the position and teach at small schools in the provinces for no money. His contributions to Islamic scholarship range from responding to the challenges of Aristotelian philosophy to creating a new type of Islamic mysticism and integrating both these traditions-falsafa and Sufism-into the Sunni mainstream. This book offers a comprehensive study of al-Ghazali's life and his understanding of cosmology-how God creates things and events in the world, how human acts relate to God's power, and how the universe is structured. Frank Griffel presents a serious revision of traditional views on al-Ghazali, showing that his most important achievement was the creation of a new rationalist theology in which he transformed the Aristotelian views of thinkers such as Avicenna to accord with intellectual currents that were well-established within Muslim theological discourse. Using the most authoritative sources, including reports from al-Ghazali's students, his contemporaries, and his own letters, Griffel reconstructs every stage in a turbulent career. The al-Ghazali that emerges offers many surprises, particularly on his motives for leaving Baghdad and the nature of his "seclusion" afterwards. Griffel demonstrates that al-Ghazali intended to create a new cosmology that moved away from concerns held earlier by Muslim theologians and Arab philosophers. This new theology aimed to provide a framework for the pursuit of the natural sciences and a basis for Islamic science and philosophy to flourish beyond the 12th century. Al-Ghazali's Philosophical Theology is the most thorough examination to date of this important thinker.
