"In some countries the Constitution only formalises, in a legal instrument, a historical consensus of values and aspirations evolved incrementally from a stable and unbroken past to accommodate the needs of the future. The South African Constitution is different: it retains from the past only what is defensible and represents a decisive break from, and a ringing rejection of, that part of the past which is disgracefully racist, authoritarian, insular, and repressive and a vigorous identification of and commitment to a democratic, universalistic, caring and aspirationally egalitarian ethos expressly articulated in the Constitution. The contrast between the past which it repudiates and the future to which it seeks to commit the nation is stark and dramatic."
January 1, 1970
