The changes in our life must come from the impossibility to live otherwise than according to the demands of our conscience.

出自《抱朴子·备阙》。使用弹弓打鸟，泥丸比千金更适用。

It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair, we had everything before us, we had nothing before us, we were all going direct to Heaven, we were all doing direct the other way.

中国哲学的精髓在于其对宇宙和人生的动态和整体观。
