Unlinke Sophie's World, which is first and foremost a chronological introduction to the life and work of individual philosophers, Princess Metaphysica takes a thematic approach to western philosophy based on three big questions:
What can I know?
What should I do?
What may I hope for?
Princess Metaphysica is an amusing and intelligent book which carries ist readers off on an adventurous journey through the land of Philosophica, and encourages them to think for themselves. The plot is ingrained in a witty, absorging and comprehensible diction. It animates to think further and in some cases baffles the reader.
This is the exciting tale of three companions who set off on a journey through the land of Philosophica in search of the oldest questions in the world. On the way they encounter not only gnomes, withces, whirlwinds, sword-fights and revolutions, but also some exciting adventures in their own minds.
Above all, Princess Metaphysica inspires young readers to think about the world withou limiting their imagination.
