C.S. Lewis in a letter to Arthur Greeves, 22 June 1930:
Tolkien once remarked to me that the feeling about home must have been quite different in the days when a family had fed on the produce of the same few miles of country for six generations, and that perhaps this was why they saw nymphs in the fountains and dryads in the woods – they were not mistaken for there was in a sense a real (not metaphorical) connection between them and the countryside. What had been earth and air & later corn, and later still bread, really was in them.
We of course who live on a standardised international diet (you may have had Canadian flour, English meat, Scotch oatmeal, African oranges, & Australian wine to day) are really artificial beings and have no connection (save in sentiment) with any place on earth. We are synthetic men, uprooted. The strength of the hills is not ours.
