To feel much for others and little for ourselves； to restrain our selfishness and exercise our benevolent affections， constitute the perfection of human nature.

孔子说：“祭奠别人的先人，是谄媚；遇到符合道义的事不敢做，是懦夫。”

创新不仅仅是创造新事物，而是让现有的事物变得更好。

没有单一版本的历史；只有不同的视角。

The future of coal lies in clean and efficient utilization.

真相很少是纯粹的，也从不简单。

One tells as few lies as possible only by telling as few lies as possible, and not by having the least possible opportunity to do so.

创新是解决世界许多问题的关键，它需要实验和冒险的自由。
