George Orwell, The Road to Wigan Pier
, chapter 1:
The whole of the industrial districts are really one enormous town, of about the same population as Greater London but, fortunately, of much larger area; so that even in the middle of them there is still room for patches of cleanness and decency. That is an encouraging thought. In spite of hard trying, man has not yet succeeded in doing his dirt everywhere. The earth is so vast and still so empty that even in the filthy heart of civilization you find fields where the grass is green instead of grey; perhaps if you looked for them you might even find streams with live fish in them instead of salmon tins.
William Blake, letter to John Trusler (August 23, 1799):
I see Every thing I paint In This World, but Every body does not see alike. To the Eyes of a Miser a Guinea is more beautiful than the Sun & a bag worn with the use of Money has more beautiful proportions than a Vine filled with Grapes. The tree which moves some to tears of joy is in the Eyes of others only a Green thing that stands in the way.
