“Now then, Mr. Crab," said the zebra, "here are the people I told you about; and they know more than you do, who live in a pool, and more than I do, who live in a forest. For they have been travelers all over the world, and know every part of it.""There's more of the world than Oz," declared the crab, in a stubborn voice."That is true," said Dorothy; "but I used to live in Kansas, in the United States, and I've been to California and to Australia--and so has Uncle Henry.""For my part," added the Shaggy Man, "I've been to Mexico and Boston and many other foreign countries.""And I," said the Wizard, "have been to Europe and Ireland.""So you see," continued the zebra, addressing the crab, "here are people of real consequence, who know what they are talking about.”
“I cannot understand why you should wish to leave this beautiful country and go back to the dry, gray place you call Kansas.""That is because you have no brains," answered the girl. "No matter how dreary and gray our homes are, we people of flesh and blood would rather live there than in any other country, be it ever so beautiful. There is no place like home." The Scarecrow sighed."Of course I cannot understand it," he said. "If your heads were stuffed with straw, like mine, you would probably all live in beautiful places, and then Kansas would have no people at all. It is fortunate for Kansas that you have brains.”
“I think,' said the little Queen, smiling, 'that your friend must be the richest man in all the world.' 'I am,' returned the Scarecrow; 'but not on account of my money. For I consider brains to be far superior to money, in every way. You may have noticed that if one has money without brains, he cannot use it to advantage; but if one has brains without money, they will enable him to live comfortably to the end of days.' 'At the same time,' declared the Tin Woodman, 'you must acknowledge that a good heart is a thing that brains cannot create, and that money cannot buy. Perhaps, after all it is I who am the richest man in all the world.' 'You are both rich, my friends,' said Ozma gently; 'and your riches are the only riches worth having - the riches of content!' - The Marvellous Land Of Oz by L. Frank Baum pg 192 chapter 24”
“The Scarecrow watched the Woodman while he worked and said to him "I cannot think why this wall is here nor what it is made of." "Rest you brains and do not worry about the wall," replied the Woodman, "when we have climbed over it we shall know what is on the other side.”
“Well, I cannot claim any great experience in life,' the Saw-Horse answered for himself; 'but I seem to learn very quickly, and often it occurs to me that I know more than any of those around me.' 'Perhaps you do,' said the Emperor; 'for experience does not always mean wisdom. - The Marvellous Land Of Oz by L. Frank Baum pg 89 chapter 11”
“Scarecrow: I haven't got a brain... only straw. Dorothy: How can you talk if you haven't got a brain? Scarecrow: I don't know... But some people without brains do an awful lot of talking... don't they? Dorothy: Yes, I guess you're right.”
“I think you are a very bad man," said Dorothy."Oh, no, my dear; I'm really a very good man, but I'm a very bad Wizard, I must admit.”
