--《伊索寓言》
I who am blind can give one hint to those who see-one admonition to those who would make full use of the gift of sight:Use your eyes as if tomorrow you would be stricken blind.And the same method can be applied to the other senses.Hear the music of voices,the song of a bird,the mighty strains of an orchestra,as if you would be stricken deaf tomorrow.Touch each object you want to touch as if tomorrow your tactile sense would fail.Smell the perfume of flowers,taste with relish each morsel,as if tomorrow you could never smell and taste again.Make the most of every sense;glory in all the facets of pleasure and beauty which the world reveals to you through the several means of contact which Nature provides.But of all the senses,I am sure that sight must be the most delightful.
我，一个盲人，向你们有视力的人做一个提示，给那些善于使用眼睛的人提一个忠告：想到你明天有可能变成瞎子，你就会好好使用你的眼睛。这样的办法也可适用于别的官能。想到你明天有可能变成聋子，你就会更好地去聆听声响，鸟儿歌唱，管弦乐队铿锵的旋律；去抚摸你触及的那一切吧，假如明天你的触觉神经就要失灵；去嗅闻所有鲜花的芬芳，品尝每一口食物的滋味吧，假如明天你就再也不能闻也不能尝了。让每一种官能都发挥它最大的作用，为世界通过大自然提供的各种接触的途径向你展示的多种多样的欢乐和美的享受而自豪吧。不过在所有官能中，我相信视力是最令人赏心悦目的。
