All of us here in this Yard, at one time or another, have seen human tragedies that broke our hearts, and yet we did nothing - not because we didn't care, but because we didn't know what to do. If we had known how to help, we would have acted.

　　此刻在這個院子里的所有人，生命中總有這樣或那樣的時刻，目睹人類的悲劇，感到萬分傷心。但是我們什么也沒做，并非我們無動于衷，而是因為我們不知道做什么和怎么做。如果我們知道如何做是有效的，那么我們就會采取行動。

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

　　改變世界的阻礙，并非人類的冷漠，而是世界實在太復雜。

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

　　為了將關心轉變?yōu)樾袆?，我們需要找到問題，發(fā)現(xiàn)解決辦法的方法，評估后果。但是世界的復雜性使得所有這些步驟都難于做到。

　　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.

　　即使有了互聯(lián)網和24小時直播的新聞臺，讓人們真正發(fā)現(xiàn)問題所在，仍然十分困難。當一架飛機墜毀了，官員們會立刻召開新聞發(fā)布會，他們承諾進行調查、找到原因、防止將來再次發(fā)生類似事故。
