This profound work by Ahmed Harithi delves into the intellectual legacy of the Mu'tazila school of Islamic theology, renowned for its emphasis on reason and rational thought. It meticulously examines their concept of 'rational judgments' (ahkam 'aqliyya) and explores how these philosophical underpinnings intersect with, and contribute to, the broader principles of natural law. Harithi's analysis sheds light on the Mu'tazila's unique approach to ethics, justice, and divine attributes, offering a compelling perspective on the interplay between theological doctrine and universal moral frameworks. The book is essential reading for scholars of Islamic thought, legal philosophy, and comparative religion.
