"Imagination is more important than knowledge. Knowledge is limited to what we already know and understand, while imagination embraces the entire world and all there ever will be to discover."
"The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful."
"If we listened to our intellect, we'd never have a love affair. We'd never do a pretty thing. We'd never fall in love, we'd never go to war."
"Thought is only a flash between two long nights, but this flash is everything."
