把这一句，留给此刻的你

Human progress is neither automatic nor inevitable... Every step toward the goal of justice requires sacrifice, suffering, and struggle; the tireless exertions and passionate concern of dedicated individuals.

人类的进步既不是自动的，也不是不可避免的……迈向正义目标的每一步都需要牺牲、痛苦和斗争;奉献的个人孜孜不倦的努力和热情的关心。

— Martin Luther King Jr 马丁·路德·金
