For some thoughts, which sure would be the most beautiful, vanish before we can rightly scan their features; as though a god, travelling by our green highways, should but ope the door, give one smiling look into the house, and go again for ever.
有些念头想必美丽至极,却在我们看清它们的面容之前便消逝了;仿佛一位神明沿着绿意盎然的大路行来,只推开门,微笑着向屋内看上一眼,便永远离去。
