I had a very happy childhood, but I wasn't that happy a child. I liked being alone and creating characters and voices. I think that's when your creativity is developed, when you're young. I liked the world of the imagination because it was an easy place to go to.

We especially need imagination in science. It is not all mathematics, nor all logic, but it is somewhat beauty and poetry.

Were it not for imagination a man would be as happy in arms of a chambermaid as of a duchess.

An idea is salvation by imagination.

To treat your facts with imagination is one thing, to imagine your facts is another.
