“In this vast tapestry of the interaction of Muslims with each other, and with other cultures and faiths, there is one tradition that unfailingly continues the progressive heritage of classical Islam — profoundly intellectual, open, tolerant, pacific — and in particular one leader who has made it especially attuned to the many difficulties of the world today. That would be Ismailism and its revered Imam, the current Aga Khan IV.” — Michael Hamilton Morgan
