This book is a translation of "Maghze Mutafakkir Jehan Shia", the famous Persian book, which has been published four times in Tehran, Iran. The Persian book is itself a translation from a French thesis published by The Research Committee of Strasbourg, France, about the contribution made by Imam Jafar al-Sadiq (A.S.) to science, philosophy, literature and irfan (gnosticism).

'Kaukab Ali Mirza' did the English translation from Persian

Members of the Research Committee have done a wonderful job and deserve thanks and gratitude from all those who love the Imam. However, it must be pointed out that when the learned scholars, who were engaged in research, failed to find worldly sources of the Imam IS knowledge, they indulged in wild speculations and guesswork and were even guilty of misrepresenting historical facts to prove that Imam Mohammed al-Baqar and Jafar al-Sadiq (A.S.) had acquired their knowledge through the following sources:

a. The Great Library of Alexandria.

b. Coptic Scholars of Egypt.

c. Books of Greek Philosophers

d. Persian Physicians.
