" A CITY IS AS much a state of mind as a place—a set of perceptions of place. On the last train home to Mullaghbrack or Gortyfarnham or half a hundred other BallyBogMans, two farmers fall to reviewing their experiences of the big city. One has walked the streets and avenues and come away with memories of glistening steeples and dreaming spires, monuments to men of bearing and import, Palladian porticos and grand civic cupolas, pillars, piers, and palisades, and the air full of singing birds. The other has walked the same streets, yet his memories are of grey brick tenements shouldering against each other like nervous thugs; cracked fanlights, windows boarded over with card, baby carriages full of coal or potatoes, tramps in doorways, cabbage leaves underfoot, the perfume of urine and porter, pressing people with voices like flatirons. They might have visited cities continents apart, but it is the same city. "
