4 . 富兰克林(Benjamin Franklin,1706-1790)是美国著名的政治家和物理学家,去世后留下的财产并不可观,大致只有英镑.但令人惊奇的是,他竟然留下了一份分配几百万英镑财产的遗嘱!这份遗嘱是这样写的:
“……英镑赠给波士顿的居民,如果他们接受了这
英镑,那么这笔钱应托付给一些挑选出来的公民,他们得把这钱按每年
的利率借给一些年轻的手工业者去生息,这笔钱过了
年增加到
英镑.我希望那时候用
英镑来建立一座公共建筑物,剩下的
英镑拿去继续生息
年.在第二个
年末了,这笔款增加到
英镑,其中
英镑还是由波士顿的居民来支配,而其余的
英镑让马萨诸塞州的公众来管理,从此之后,我可不敢多作主张了.”
你认为富兰克林的设想有道理吗?为什么?
