Alber Nasri Nader's 'The Philosophy of the Mutazilite' is a profound exploration into the intellectual bedrock of early Islamic thought. This comprehensive work, presented in a single volume combining two parts, delves deeply into the doctrines and contributions of the Mutazila, a significant school of rationalist theology that flourished in the early centuries of Islam. The book meticulously examines their views on divine justice, human free will, the createdness of the Quran, and the nature of God, providing invaluable insights into their profound impact on Islamic intellectual history. Nader’s analysis sheds light on how these 'earliest philosophers' shaped theological discourse and laid groundwork for subsequent philosophical traditions.
