There are no ideal cities any more than there is an ideal television set. The future requires flexibility and a capacity for change and an adaptation to newer concepts and technologies without any utopian notion of final development. I believe future generations will evolve their own social arrangements. I do not believe in any final frontiers, and the future will continue to undergo changes based upon successive phases of social development.

Being civilized is an ongoing process and not attainable. The same is true for intelligence. An intelligent electrical engineer of 75 years ago could not get a job today. He would be educated in antiquated terms that evolved from earlier times.
