“All the same,' said the Scarecrow, 'I shall ask for brains instead of a heart; for a fool would not know what to do with a heart if he had one.'I shall take the heart,' returned the Tin Woodman, 'for brains do not make one happy, and happiness is the best thing in the world.”

“I shall take the heart. [...] For brains do not make one happy, and happiness is the best thing in the world.”

“Oh, I see;" said the Tin Woodman. "But, after all, brains are not the best things in the world."Have you any?" enquired the Scarecrow.No, my head is quite empty," answered the Woodman; "but once I had brains, and a heart also; so, having tried them both, I should much rather have a heart.”

“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.”

“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”

“But that isn't right. The King of Beasts shouldn't be a coward,'" said the Scarecrow.'I know it,' returned the Lion, wiping a tear from his eye with the tip of his tail. 'It is my great sorrow, and makes my life very unhappy. But whenever there is danger, my heart begins to beat fast.''Perhaps you have heart disease,' said the Tin Woodman.'It may be,' said the Lion.”
