“If you want your children to be intelligent, read them fairy tales. If you want them to be more intelligent, read them more fairy tales.”

“Creativity is intelligence having fun.”

“The measure of intelligence is the ability to change.”

“The true sign of intelligence is not knowledge but imagination.”

“Intelligence is not the ability to store information, but to know where to find it.”

“I am not more gifted than the average human being. If you know anything about history, you would know that is so--what hard times I had in studying and the fact that I do not have a memory like some other people do… I am just more curious than the average person and I will not give up on a problem until I have found the proper solution. This is one of my greatest satisfactions in life--solving problems--and the harder they are, the more satisfaction do I get out of them. Maybe you could consider me a bit more patient in continuing with my problem than is the average human being. Now, if you understand what I have just told you, you see that it is not a matter of being more gifted but a matter of being more curious and maybe more patient until you solve a problem.”

“Intelligent life on other planets? I'm not even sure there is on earth!”
