我们必须设计本质上是恢复性和再生性的系统。
So foul and fair a day I have not seen.
Hold to the now, the here, through which all future plunges to the past.
The body is the first territory of political struggle.
释义：上顺应于天，下取悦于民。使民众喜悦，人民便忘记了劳苦；用喜悦战胜困难，民众就会忘掉死亡的威胁，喜悦的作用太大了，它能勉励民众！
To understand the present, you must first understand the past.
