idn’t care, but because we didn’t know what to do. if we had known how to help, we would have acted.

　　此刻在这个院子里的所有人，生命中总有这样或那样的时刻，目睹人类的悲剧，感到万分伤心。但是我们什么也没做，并非我们无动于衷，而是因为我们不知道做什么和怎么做。如果我们知道如何做是有效的，那么我们就会采取行动。

　　the barrier to change is not too little caring; it is too much complexity.

　　改变世界的阻碍，并非人类的冷漠，而是世界实在太复杂。

　　to turn caring into action, we need to see a problem, see a solution, and see the impact. but complexity blocks all three steps.

　　为了将关心转变为行动，我们需要找到问题，发现解决办法的方法，评估后果。但是世界的复杂性使得所有这些步骤都难于做到。

　　even with the advent of the internet and 24-hour news, it is still a complex enterprise to get people to truly see the problems. when an airplane crashes, officials immediately call a press conference. they promise to investigate, determine the cause, and prevent similar crashes in the future.

　　即使有了互联网和24小时直播的新闻台，让人们真正发现问题所在，仍然十分困难。当一架飞机坠毁了，官员们会立刻召开新闻发布会，他们承诺进行调查、找到原因、防止将来再次发生类似事故。

　　but if the officials were brutally honest, they would say: "of all the people in the world who died today from preventable causes, one half of one percent of them were on this plane. we’re determined to do everything possible to solve the problem that took the lives of the one half of one percent."

　　但是如果那些官员敢说真话，他们就会说：“在今天这一天，全世界所有可以避免的死亡之中，只有0.5%的死者来自于这次空难。我们决心尽一切努力，调查这个0.5%的死亡原因。”
