Persian scholar Al-Ghazali feared for any country where morals were lagging behind brains.
Al-Ghazali, known in Medieval Europe as Algazel, was a Persian scholar roughly contemporary with Anselm of Canterbury. In 1095, feeling compromised by political and academic expectations, Ghazali abruptly left his prestigious teaching post and embarked on a ten-year pilgrimage to Damascus, Jerusalem and Mecca. The Revival of the Religious Sciences was the fruit of his soul-searching, and one of the most important Islamic works after the Quran itself.
