“I am continually dumfounded by the fact that while the life of imagination has been responsible for the production of every human advance—whether of an artistic or material nature—the imagination is looked down on as something effeminate and childish. It requires imagination to discover the facts of nature, for you must suppose how things are before you can set up an hypothesis to explore the facts. Imagination is responsible for all the empire building, for you must imagine the possibilities before you can attempt to put them into practice. The poets have no monopoly on the life of the imagination, although they are devoted entirely to it, and everyone who has ever built anything new must have imagined it to begin with and so have been something of an originator.”
