"I have come to believe that a great teacher is a great artist and that there are as few as there are any other great artists. Teaching might even be the greatest of the arts since the medium is the human mind and spirit."

历史进程是不连续的，重大变革往往是突然发生的，而不是渐进的。

My work is my observation of the world.

常想到会悔恨终生，就不能不尽孝心；常想到度日的艰难，就不得不节约费用；常想到人的生命脆弱，就不得不珍惜心神；常想到世态人情，就不得不立志奋发；常想到法网恢恢，疏而不漏，就不能让自己胡作非为；常想到生命易失，就不得不忍气耐性。
