Professor Ali Mazrui, originally of Makarere University in East Africa, has passed away. Eulogies are coming out fast and furious, among them this: There is one crucial similarity between prophets on the one hand and public intellectuals on the other. Both seek to define the terms of the debate in an argument. But the terms of a debate cannot be defined alone; this endeavor requires a worthy adversary. It is in this sense that Mazrui and Rodney defined the terms of the debate in the 1960s.
