Sophie Amundsen is a fourteen-year-old girl, who starts to receive very strange letter from a philosopher who asks her questions. The first two letters include these: "Who are you?" and "Where does the world come from?" These questions get Sophie thinking seriously about things she has never thought about before she felt her heart beating fast as she opened the mailbox. At first she found only a letter from the bank and some big brown envelopes for her mother. Darn! Sophie had hoped to find another letter from the unknown sender. As she closed the gate behind her, she noticed her own name on one of the big envelopes. Turning it over, she saw written on the back: "Course in Philosophy, Handle with care." Inside the envelope there were three typed pages held together with a paper clip. Sophie began to read. What is philosophy? A Greek philosopher who lived more than two thousand years ago, believed that philosophy had its origin in people's sense of wonder.
