‘… time in jail was not wasted. He had gone to jail as an angry, frustrated young activist. In prison the fires of adversity purified him and removed the dross; the steel was tempered. He learned to be more generous in his judgment of others, being gentle with their foibles. It gave him a new depth and serenity at the core of his being, and made him tolerant and magnanimous to a fault, more ready to forgive than to nurse grudges – paradoxically regal and even arrogant, and at the same time ever so humble and modest’. – Desmond Tutu, ‘Setting Free the Past’, Oliver R. Tambo Lecture delivered at Georgetown University.
