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.

Al-Ghazali is arguably one of the most influential thinkers in the history of Islam, and his writings have received greater scholarly attention in the West than those of any other Muslim scholar. This study explores an important dimension of his thought that has not yet been fully examined, namely, his polemical engagement with the Ismailis of the Fatimid and early Alamut periods. Published in association with The Institute of Ismaili Studies.

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.

An Introduction to Metalogic is a uniquely accessible introduction to the metatheory of first-order predicate logic. No background knowledge of logic is presupposed, as the book is entirely self-contained and clearly defines all of the technical terms it employs. Yaqub begins with an introduction to predicate logic and ends with detailed outlines of the proofs of the incompleteness, undecidability, and indefinability theorems, covering many related topics in between.

Ayn al-Qudat is one of the geniuses of Islamic intellectual history and has even been described as the true father of deconstructionism. This text provides a clearly-written critical introduction to the intellectual, literary, religious and philosophical struggles of the 12th century as expressed by one of Islam's greatest and most radical writers.

Although Abu Hamid Muhammad al-Ghazali lived a relatively short life (1058-1111), he established himself as one of the most important thinkers in the history of Islam. The Incoherence of the Philosophers, written after more than a decade of travel and ascetic contemplation, contends that while such Muslim philosophers as Avicenna boasted of unassailable arguments on matters of theology and metaphysics, they could not deliver on their claims; moreover, many of their assertions represented disguised heresy and unbelief. Despite its attempted refutation by the twelfth-century philosopher Ibn Rushd, al-Ghazali's work remains widely read and influential.
