After the procedure, Charlie's IQ increased threefolds. He began to see the world with new eyes. The things that gave him simple pleasures before seem ridiculous and stupid now. He realized the jokes he once shared with friends were actually mockings of his intelligence. He also developed a thirst for knowledge and learned everything he can. He became so mentally superior he belittled and disregarded the opinion of others. The story continued to show that the more Charlie knew (about the world and himself) the more he became depressed and aggressive.
"I don't know what's worse: to not know what you are and be happy, or to become what you've always wanted to be, and feel alone." -Charlie Gordon
Charlie and Algernon will intellectually stimulate and move you to tears at the same time. Happy reading!
