Reflections in Prison

""The most urgent problem facing us is that of unity... there is a wide difference between constructive criticism that will pave the way to a consensus and mere invective that tends to harden the differences."" So begins Nelson Mandela's ""Clear the Obstacles and Confront the Enemy,"" an essay on strategies and ""stumbling blocks"" for the antiapartheid movement. It's one of the nine pieces in Reflections in Prison: Voices from the South African Liberation Struggle, a collection of essays, mostly about the future of the resistance movement, by South African activists written in the Robben Island prison. The book is edited by Mac Maharaj, a founding member of the antiapartheid movement, and includes a foreword by Desmond Tutu. (May)
