"Every book is a door to another world, waiting to be opened by the curious mind."
郦波在讲座中引用马克·吐温的话并加以阐释
地理学的研究是对地球作为人类居住地的研究。
你有敌人?很好。这说明在你的生命中的某个时刻,你曾经呐喊过。
I am too intelligent, too demanding, and too resourceful for anyone to be able to take charge of me entirely. No one knows me or loves me completely. I have only myself.
世界不是一个需要解决的问题;它是一个我们所属的生命体。
