It is here [in mathematics] that the artist has the fullest scope of his imagination.

Don't talk to me of your Archimedes' lever. He was an absentminded person with a mathematical imagination. Mathematics commands all my respect, but I have no use for engines. Give me the right word and the right accent and I will move the world.

Man lives by imagination.

No great artist ever sees things as they really are. If he did he would cease to be an artist.

To be a true artist you have to play the way you feel - not the way others think you should feel.

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