Sophie's World, by Jostein Garrder. A fiction piece on the history of philosophy. A story centred around Sophie, and a series of letters she receives from her father teaching her about the great philosophers. A fun, interesting, and adventurous story that culminates in a wondrous ending.
Life is both sad and solemn. We are led into a wonderful world, we meet one another here, greet each other - and wander together for a brief moment. Then we lose each other and disappear as suddenly and unreasonably as we arrived.
