"Oh, yes indeed." Answered the Tin Woodman. "There's only one Great Wizard. All worlds are created by him, and he loves every soul who resides in his creation: even the Wicked Witch of the Deep South." "How could He love someone so evil?" questioned Dorothy. "I was wondering that myself," said the Scarecrow. "Well," said the Tin Woodman. "He must realize that she's her own worst enemy, and he's just waiting for her to catch on to that fact. I don't know why some people are so filled with hatred. As I told you, Dorothy, ever since I've had a heart I've been having a lot of feelings, and I've been trying to understand why some people have a lot of love inside them, and enjoy helping others; while some only care about themselves. Perhaps the people who can't feel love and compassion have no heart at all." "Or perhaps something happens to them that causes their heart to harden," said the Lion. "Not to change the subject," said the Scarecrow. "But I've been reading about the creation of mortals. There are lots of books on the subject, and sometimes the books contradict one another. Some talk about the slow evolution of tiny simple organisms into large complex organisms. While others talk of the instantaneous creation of complex organisms, for example, Adam and Eve -- who were, supposedly, the very first mortals. It's all very complicated. "Well," said the Tin Woodman. "You don't have to accept everything you read; you have to form your own opinion. That's why you've got a brain. Books are just people's ideas, No one can really prove anything. Even scientists differ in their analysis of the same evidence. "That's correct," said the Scarecrow. "Ever since I got my brain, I've been thinking a lot. And some of the things I've read, I agree with, and some I don't agree with. I know some people who have read only one book in which the creation of mortals is explained, and they say that version is true because the people who wrote it were inspired by the Great Wizard." "I haven't thought a lot about it," said Dorothy. "But I think people should read all the books written on a given subject before drawing a conclusion. Even if they didn't accept everything they read, they would at least be stimulated by the many ideas put forth. I've heard that people who have a long established belief about something will often refuse to study all the available literature on the subject, but will close their minds off completely. They have made their minds up as to the truth of the matter, and don't want to hear another word on the subject." "Truth is where you find it," said the Tin Woodman. "What does that mean?" said the Scarecrow. "Isn't that the point of the whole thing?" said Dorothy. "Since no one really knows for sure what is totally true or not true, we owe it to ourselves not to be satisfied with what is told to us, but to question and to search for ourselves. In other words, continue the search for truth all of our lives with an open mind."
