Wissen und das Leib-Seele-Problem. Eine Verteidigung der Interaktionstheorie

After The Logic of Scientific Discovery and The Open Society, the two books combined in this volume are Popper's third principal work. The book contains his theory of interaction as a solution to the ancient body-mind problem which continues to puzzle philosophers and scientists to this very day. His theory of evolutionary emergence maintains that the »world 2« of consciousness emerged from the physical »world 1« and produced »world 3« of the products of the human mind. Worlds 2 and 3 are autonomous and follow their own laws. This enables the conscious world 2 to act on the brain and therefore on world 1. Because consciousness interacts intensively with world 3 of language and objective knowledge rather than being a mere neural activity, man has a free will. Materialism and behaviorism have been proven wrong; freedom and responsibility are not an illusion.
