如果不理解两者，就无法理解个人的生活或社会的历史。
Neither the life of an individual nor the history of a society can be understood without understanding both.
Without models, we would be wandering in the dark when it comes to predicting climate change.
To know is nothing at all; to imagine is everything.
文学的研究即是对生活本身的研究。
能源的未来在于平衡当今的需求与未来的责任。
