美好生活是一个过程，而不是一种状态。它是一个方向，而不是一个目的地。

The right of nature...is the liberty each man hath to use his own power as he will himself for the preservation of his own nature.

The only way to get rid of a temptation is to yield to it.

Whenever you find yourself on the side of the majority, it is time to pause and reflect.

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.

Future robots will be more intelligent and more human-like.
