哈佛公开课 - 幸福课课程节选

We have to not talk-- just talk about the good things in the life, but the good of life itself, and we have to notice that perhaps on certain views, for certain cases, it's not really the case that when I die I'm being deprived of a good life.

我们不但要看到-,生活中的美好事物，还要看到活着本身的好处，我们发现也许有某些观点，在某些情况下，情况则不完全是这样,即我死之后不会被剥夺美好的生活。
