A person incapable of imaging another world than given to him by his senses would be subhuman, and a person who identifies his imaginary world with the world of sensory fact has become insane.
W. H. AudenIn a land which is fully settled, most men must accept their local environment or try to change it by political means; only the exceptionally gifted or adventurous can leave to seek his fortune elsewhere. In America, on the other hand, to move on and make a fresh start somewhere else is still the normal reaction to dissatisfaction and failure.
