What does it mean to be free? Is there an absolute freedom of will? The philosopher Peter Bieri presents a variety of answers to the question of free will as if on a stage: In small, constantly varied scenes, he entangles seemingly compelling notions of freedom in contradictions until, in the end, the principles of true freedom can be recognized. The book rediscovers the freedom we have—whether we want it or not. It is clear to the point of beauty and as exciting as a novel. Rüdiger Safranski.
