This work demonstrates how falsafah (which linguistically refers to a group of commentaries by Muslim scholars associated with their readings of "The Corpus Aristotelicum") in Iran has been always closely linked with religion. It demonstrates that the blending of the new natural theology with Iranian culture created an intellectual climate that made Iran the center of falsafah in the Medieval world. The author begins this book by exploring the analytical arguments and methodologies presented as the subject of the first-philosophy (metaphysics) in the works of Aristotle (in particular "The Nicomachean Ethics" and "Rhetoric"). Then, he tells the tale of the Muslims' progression as they came to own and expand upon Aristotle's arguments and methodologies as a measure of their own sense of spirituality. Last, Sadri surveys the implications of that sense of spirituality as it is amalgamated within the Iranian culture and today's Islamic Republic of Iran. The author's aim is to present a different perspective of falsafah (as it is received by Muslims and assimilated within Iranian culture), while maintaining a sense that captures the texture of everyday life-experiences in today's Islamic Republic of Iran. This work is thus about (contemporary) Iranian falsafah and how it remains faithful to its tradition (as falsafah has actually been integrated and practiced by Iranian scholars for the last eleven centuries). It is a tradition that has taken on the task of understanding and projecting a sense of order upon the multiplicity of forms, ideas, examples, and images that have passed through Iran from East and West; it is a story that has gathered, sheltered, and introduced a style and order of Islamic (Shi'at) falsafah.
