I'm an author. I'm convinced that metaphysics can be conducted as an exact science like atomic-resp. -nuclear physics. Out of this conviction several books and articles have been emerged.
Von der Entdeckung Gottes am Rande des Universums (-- From the discovery of God on the edge of the universe) --, published in 2005 in the Via Nova Verlag/Germany. It deals with the history of metaphysics and shows how a scientific proof of the existence of the One could look like.
