Wer bin ich - und wenn ja wie viele?

This book, written by Richard David Precht, aims to awaken and train the desire to think and encourage progressive self-knowledge and a more consciously led life.

It is structured around three main questions inspired by Immanuel Kant: 'Was kann ich wissen?

' (What can I know? ), 'Was soll ich tun? ' (What should I do?

), and 'Was darf ich hoffen? ' (What can I hope for? ).

The book combines philosophy with contemporary research on the brain, psychology, and behavior, making it a comprehensive and accessible guide to the big philosophical questions of life.
