204.It isn't the burdens of today that drive men mad. It is the regrets over yesterday and the fear of tomorrow. 真正令人发疯的不是今日的负担,而是对昨日的悔恨和对明日的恐惧。——罗伯特·哈斯汀斯
207. I object to violence because when it appears to do good, the good is only temporary; the evil it does is permanent. 我反对暴力,因为暴力带来的好处往往都是暂时的,它带来的恶果却是无穷的。——[印]穆罕达斯·甘地
