How was it possible，I asked myself，to walk for an hour through the woods and see nothing worthy of note? I who cannot see find hundreds of things to interest me through mere touch. I feel the delicate symmetry of a leaf. I pass my hands lovingly about the smooth skin of a silver birch，or the rough shaggy bark of a pine. In spring I touch the branches of trees hopefully in search of a bud，the first sign of awakening Nature after her winter’s sleep. I feel the delightful，velvety texture of a flower，and discover its remarkable convolutions； and something of the miracle of Nature is revealed to me. Occasionally，if I am very fortunate，I place my hand gently in a small tree and feel the happy quiver of a bird in full song. I am delighted to have cool waters of a brook rush through my open fingers. To me a lush carpet of pine needles or spongy grass is more welcome than the most luxurious Persian rug. To me the pageant of seasons is a thrilling and unending drama，the action of which streams through my finger tips. At times my heart cries out with longing to see all these things. If I can get so much pleasure from mere touch，how much more beauty must be revealed by sight. Yet，those who have eyes apparently see little. The panorama of color and action filling the world is taken for granted. It is Human，perhaps，to appreciate little that which we have and to long for that which we have not，but it is a great pity that in the world of light the gift of sight is used only as mere convenience rather than as a means of adding fullness to life.
Oh，the things that I should see if I had the power of sight for three days!

这类故事会激发起我们的思考：倘若身处类似的环境下，我们自己该做些什么？在那临终前的几个小时里我们会产生哪些联想？会有多少欣慰和遗憾呢？
有时我想，把每天都当作生命的最后一天来度过也不失为一种好的生命法则。这种态度重视的是人生的价值。每一天我们都应该以和善的态度、充沛的精力和热情的欣赏来度过，但当时间展现在我们面前、来日方长的时侯，我们会忽视这些东西。当然，有一些人奉行享乐主
