把这一句，留给此刻的你
The man whose life is spent in performing a few simple operations of which the effects too are, perhaps, always the same or very nearly the same, has no occasion to exert his understanding, or to exercise his invention. He generally becomes as stupid and ignorant as it is possible for a human creature to become.
如果一个人一生只从事几项简单的工作，而这些工作的效果也许总是相同的，或者几乎总是相同的，那么他就没有必要发挥他的理解力，也没有必要运用他的发明创造。他一般会变得像人类一样愚蠢和无知。
