I realized that If I had to choose, I would rather have birds than airplanes. In wilderness I sense the miracle of life, and behind it our scientific accomplishments fade to trivia. Real freedom lies in wildness, not in civilization.
The more civilized man becomes, the more he needs and craves a great background of forest wildness, to which he may return like a contrite prodigal from the husks of an artificial life.
Science has never drummed up quite as effective a tranquilizing agent as a sunny spring day.
