Collège Sadiki
Djait was born in Tunis, Tunisia to a conservative upper-middle-class family. His erudite father and some of his uncles and relatives were Islamic sages (or sheikhs), which made the name of the Djait family become traditionally associated with the Zeytouna Mosque as well as with Islamic Fiqh and Iftah (or jurisprudence). He had his secondary education at Sadiki College, where he studied French, world literature, Western philosophy, Arabic, and Islamic Studies. His training at Sadiki College made him discover Enlightenment thinkers and the ideals of the Renaissance and the Reformation which were rather different from the teachings of his family's conservative milieu.
