G. K. Chesterton 
What I Saw in America 

I have never managed to lose my old conviction that travel narrows the mind. At least a man must make a double effort of moral humility and imaginative energy to prevent it from narrowing his mind. Indeed there is something touching and even tragic about the thought of the thoughtless tourist, who might have stayed at home loving Laplanders, embracing Chinamen, and clasping Patagonians to his heart in Hampstead or Surbiton, but for his blind and suicidal impulse to go and see what they looked like. This is not meant for nonsense; still less is it meant for the silliest sort of nonsense, which is cynicism. The human bond that he feels at home is not an illusion. On the contrary, it is rather an inner reality. Man is inside all men. In a real sense any man may be inside any men.
