Looking in her mailbox one day, a fourteen-year-old Norwegian schoolgirl called Sophie Amundsen finds two surprising pieces of paper. On them are written the questions: 'Who are you?' and 'Where does the world come from?'
The writes is an enigmatic philosopher called Alberto Knox, and his two teasing questions are the biginning of an extraordinary tour through the history of Western Philosophy from the pre-Socratics to Sartre. In a series of brilliantly entertaining letters, and then in person, Alberto Knox opens Sophie's enquiring mind to the fundamental questions that philosophers have been asking since the dawn of the civilisation.
