The author establishes how the field of algebra was developed by Muslim mathematicians, which helped to spur a revolution in the field. He also rebuts a number of philosophers, including Edmund Husserl, a philosopher and writer on modern history of the period post fourteenth century A.D. For the author, the work produced in the fourteenth century is comparatively of a lower standard than that produced in the twelve and thirteenth centuries during which time the Latin scholars were in the process of understanding and appreciating what the Arab academics had produced in the variety of fields of science and in particular that of geometry, algebra and optics. The book is rich in its detail of the intellectual heritage of both the East and West. The book consists of three papers, the original work being a lecture presented by Roshdī Rāshid in French. The book is written in three languages, Arabic, English and French.
