Sophies World

Sophie Amundsen is fourteen years old when the book begins, living in Norway. She begins a strange correspondence course in philosophy.

She learns about Plato and his world of ideas and then about Aristotle, who critiqued Plato, classified much of the natural world, and founded logic and our theory of concepts.

Then, as Sophie's education continues, the Hilde situation begins to get more
