Mandela was able to guide South Africa to freedom, because he was able to see its future more clearly than those who lived through the apartheid years outside of prison. Indeed, he possessed that rare clarity of moral vision that prison – perhaps like no other environment – can nurture.
曼德拉能引导南非走向自由，因为他比狱外渡过种族隔离年代的人更能清楚预见到南非的未来。在他身上，监狱比其他任何环境更能勾画出清晰的道德目标。
