Mohsen Kadivar, a visiting professor in the religion department, spent 18 months in an Iranian prison for speaking his mind.
Kadivar, 50, who is teaching an undergraduate class and a seminar in the Divinity School, is a prominent Iranian cleric and political dissident. Most recently, along with four other leading opposition figures outside Iran, Kadivar drafted and signed an open letter calling for the resignation of Iranian President Mahmoud Ahmadinejad, free elections, the release of political prisoners, greater freedom of speech and an independent judiciary . . . .
