Once in a Thousand Years. The Life and Radical Mind of Al-Nazzam - Narin Hikma

He wrote thirty-nine books. Every single one is gone.

What remains is something harder to destroy than a book: a set of ideas so sharp, so honest, so relentlessly committed to following the argument wherever it leads, that twelve centuries of silence have not managed to extinguish them.

Ibrahim ibn Sayyar al-Nazzam lived in ninth-century Baghdad at the absolute height of the Islamic Golden Age. He was the most brilliant student of the Mu'tazilite school - and then, inevitably, its most dangerous heretic. His greatest student, the writer al-Jahiz, called him simply: a man who appears once in a thousand years.

ONCE IN A THOUSAND YEARS tells the full story of this lost genius: where he came from, what he thought, why it threatened everyone, and what it means that his ideas refused to stay buried.

What al-Nazzam argued - at a time when such arguments could end careers, erase legacies, and cost everything:

Each of these positions made enemies. Together, they made al-Nazzam the most attacked, most refuted, and most carefully erased thinker of the early Islamic world - which is another way of saying: the one who had gotten closest to something his age was not ready to accept.

His books were allowed to die. His school was absorbed and dissolved. His name became a warning in the encyclopedias of later scholarship: this is what happens when reason goes too far.

But the questions he asked never closed. They are open now.
