It sounds like you are writing an essay about Tarzan's transformation from a wild child to a civilized man. One of the themes of the book is Tarzan's struggle to reconcile his human nature with his animal upbringing. One instance where this happens is on page 126, where the author writes:
He did not know that he was a man, and yet he was a man. He did not know that he was a beast, and yet he was very much a beast. He did not know what it meant to be either one or the other, and so he was neither. He was something new, something different, something that had never been before.
This is a part of Tarzan knowing his human instincts and discovering his identity. He realizes that he is different from the apes that raised him, but he also does not fit in with the humans that he encounters. He is curious about his own origin and destiny, and he seeks to learn more about himself and the world around him. He is constantly evolving and adapting to new situations and challenges. He is a unique character that transcends the boundaries of nature and culture.
