His improvisations were far more gifted than most, in part because of his disciplined approach to political selfhood. That’s the thing that made Mandela’s strategy and his adaptations stand out. All of his selves and words and decisions were an enactment of the enduring nation he meant to live in some day. I think that is the difference between him and many of his nationalist contemporaries who ascended to power in newly independent African states between 1960 and 1990. (This, too, needs remembering today: Mandela came to nationalism in the same historical moment as Kwame Nkrumah, Julius Nyerere, Patrice Lumumba, Kenneth Kaunda, and so on.) The difference is that Mandela was always looking through the struggle to its ultimate ends, whereas most of the nationalists could see little further than the retreat of the colonial powers from the continent and the defeat of any local political rivals.
