This world of ours is a new world, in which the unit of knowledge, the nature of human communities, the order of society, the order of ideas, the very notions of society and culture have changed, and will not return to what they have been in the past. What is new is new, not because it has never been there before, but because it has changed in quality.
The fundamental magic of flying is a miracle that has nothing to do with any of its practical purposes - purposes of speed, accessibility and convenience - and will not change as they change.
The really great visual experience today is to fly over a huge city and look down into the night. It's like a tremendous jubilant Christmas tree. You just feel life is worth living - when you come down you may have some doubts.
Now here, you see, it takes all the running you can do to keep in the same place. If you want to get somewhere else, you must run at least twice as fast as that!
Man is flying too fast for a world that is round. Soon he will catch up with himself in a great rear-end collision and Man will never know that what hit him from behind was Man.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends upon the unreasonable man.
So long as all the increased wealth which modern progress brings, goes but to build up great fortunes, to increase luxury, and make sharper the contest between the House of Have and the House of Want, progress is not real and cannot be permanent.
If you strike a thorn or rose, Keep a-goin! If it hails or if it snows, Keep a-goin! 'Tain't no use to sit and whine 'Cause the fish ain't on your line; Bait your hook an' keep on tryin'. Keep a-goin!
