In this world, what we must guard against most is perfection. Look at the moon in the sky—once full, it begins to wane; the fruit on the tree—once ripe, it must fall. Only by leaving a little room for imperfection can things endure.
世界上的事情,最忌讳的就是个十全十美,你看那天上的月亮,一旦圆满了,马上就要亏厌;树上的果子,一旦熟透了,马上就要坠落。凡事总要稍留欠缺,才能持恒。
Every building should be a response to its environment.
In computing, invariants are ephemeral.
用心才能明白道理,而用心要保持虚空、专一而安静。荀子认为,人们在以前已经学到了一些知识的情况下,再学新东西的时候,容易犯经验主义的错误。生活中也是这样,我们在遇到一件事时,总是容易按以往的经验去判断,这样可能是错的。最好能保持虚空的状态,专心地看待这件事,然后可以想想是否可以借鉴以往的经验。
