Is this book more than just a fantasy thrill? Some literary critics have proposed that Baum - a strong believer in individualism and self-confidence - is working with themes about self-esteem and self-reliance. This is quite plausible, especially considering that the brains, heart and courage sought by the scarecrow, woodsman and lion are abilities that they clearly already possess - they just need to recognize them and use them. And Dorothy herself discovers that when the wizard can't help her, she must and can rely on herself. Other literary critics have claimed that "The Wizard of Oz" needs to be read as an elaborate political allegory where the various characters represent various social classes and financial structures - a not impossible suggestion, but one that's somewhat difficult to defend. Ultimately, however, "The Wizard of Oz" is best enjoyed as a wonderful story. That doesn't mean it is any less of a contribution to English literature, because when appreciated as a brilliant story, you're sure to come back to it again and again, as are your children and grandchildren. It's precisely this universal appeal that makes "The Wizard of Oz" a true classic.
