约翰·格林《无比美妙的痛苦》英语名言：怎么知道快乐呢

“Without pain, how could we know joy?' This is an old argument in the field of thinking about suffering and its stupidity and lack of sophistication could be plumbed for centuries but suffice it to say that the existence of broccoli does not, in any way, affect the taste of chocolate.”

― John Green, The Fault in Our Stars

谷歌翻译，仅供参考：

“没有痛苦，我们怎么知道快乐 呢？”这是一个古老的争论，关于痛苦的思考，它的愚蠢和缺乏老练可以在几个世纪内得到证实，但足以说明，花椰菜的存在并不能影响巧克力的味道。

―约翰·格林《无比美妙的痛苦》
