who needs a heart in the wizard of oz
Tin Woodman The Wizard turns out to be a "humbug" and can only provide a placebo heart made of silk and filled with sawdust. However, this is enough to please the Tin Woodman, who, with or without a heart, was all along the most tender and emotional of Dorothy's companions (just as the Scarecrow was the wisest and the Cowardly Lion the bravest). When he accidentally crushes an insect, he is grief-stricken and, ironically, claims that he must be careful about such things, while those with hearts do not need such care. This tenderness remains with him throughout the series, as in The Patchwork Girl of Oz, where he refuses to let a butterfly be maimed for the casting of a spell.[2]
