窗子许里面人看出去,同时也许外面人看进来,所以在热闹地方住的人要用窗帘子,替他们私生活做个保障。晚上访人,只要看窗里有无灯光,就约略可以猜到主人在不在家,不必打开了门再问,好比不等人开口,从眼睛里看出他的心思。关窗的作用等于闭眼。天地间有许多景象是要闭了眼才看得见的,比如梦。假使窗外的人声物态太嘈杂了,关了窗好让灵魂自由地去探胜,安静地默想。

传道者感叹到:“著书立说没有止境”,却没发觉他已高度评价了作家这一职业。的确,写作、旅行、积聚财富都是没有终结的。一个问题引发另外一个问题。我们不断学习,且永远达不到心中所渴望的那般学识渊博。我们永远雕刻不出自己心仪的塑像。当发现一个新大陆,或翻过一座山脉时,我们总会看到远方还有未曾涉足的海洋与陆地。宇宙浩渺,总会有供我们勤奋努力的东西,总会有供我们探索的空间。它不像卡莱尔的著作,可以读完。即使在其一角,在一个私人花园,或一个农庄附近,四季轮回,天气瞬息万变,哪怕在那里生活了一辈子,也总会有让我们惊喜的事情。
During the 30 years since, America and China have exchanged many handshakes of friendship and commerce. And as we have had more contact with each other, the citizens of both countries have gradually learned more about each other. It was my honor to visit China in 1975. Some of you were not even born then. It shows how old I am. And a lot has changed in your country since then. China has made amazing progress in openness and enterprise and economic freedom. And this progress previews China’s great potential. China has joined the World Trade Organization, and as you live up to its obligations, they inevitably will bring changes to Chinese legal system. A modern China will have a consistent rule of law to govern commerce and secure the rights of its people. The new China you generation is building will need the profound wisdom of your traditions. The lure of materialism challenges society in our country—and in many successful countries. All these changes will lead to a stronger, more confident China, a China that can astonish and enrich the world, a China that you generation will help create. This is one of the most exciting times in the history of your country, a time when even the grandest hopes seem in your reach. My nation offers you our respect and our friendship.
