时光的唯一作用就在于它筛出了糟粕，因为只有真正优秀的文学作品才能存留下来。那些杰出的伟人不会从这个世界消失，它们的灵魂保存在书本里，云游四方。书是活的声音，它所包含的智慧今人依然聆听。因此，我们依然时刻受到过去伟人的影响。那些世界巨匠像过去一样活在人世间。

参考翻译

The only effect of time has been to sift out the bad products;for nothing in literature can long survive but what is really good.The great and good do not die from this world.Embalmed in books,their spirits walk abroad.The book is a living voice.It is an intellect to which one still listens.The great and the good will be always remembered as time goes by.
