“I am part of all that I have met;Yet all experience is an arch wherethroughGleams that untravelled world, whose margin fadesFor ever and for ever when I move.How dull it is to pause, to make an end,To rust unburnished, not to shine in use!As though to breath were life. Life piled on lifeWere all too little, and of one to meLittle remains: but every hour is savedFrom that eternal silence, something more,A bringer of new things; and vile it wereFor some three suns to store and hoard myself,And this grey spirit yearning in desireTo follow knowledge like a sinking star,Beyond the utmost bound of human thought.”
