他的原話（摘自他的英文書：“The importance of living"）：
"I call no man wise until he has made the progress from the wisdom of knowledge to the wisdom of foolishness, and become a laughing philosopher, feeling first life's tragedy and then life's comedy. For we must weep before we can laugh. Out of sadness comes the awakening and out of the awakening comes the laughter of the philosopher, with kindliness and tolerance to boot.”
