讨论学问要看其人的品行,讨论政治要考察当时的形势
爱让彼此找到方向。
我从十五岁开始致力于学习,三十岁便能自立于社会了,四十岁对各种事理不再迷惑不解,五十岁懂得了自然界的规律,六十岁对听到的事情能领会贯通,并能辨别是非真伪,七十岁时做事能随心所欲,但又不会超出礼法的规范。
The only truly secure system is one that is powered off, cast in a block of concrete and sealed in a lead-lined room with armed guards - and even then I have my doubts.
