The realist is naive in that he does not acknowledge that we do not live in the world, but only in the image we create of the world. Hoimar v. Ditfurth. The autobiography of an extraordinary thinker. First published in 1989, it is now finally available again: the inner views of a fellow being. In his last book, his life's reflection, Hoimar v. Ditfurth writes about the themes and questions that occupied him throughout his life: from natural science to politics, from the self-understanding of humanity to its place in the universe. The inner views of this thinker, who spans the sciences, reveal astonishing, unusual, and at times frightening insights, but also the comforting thought that our lives cannot be without meaning. Hoimar v. Ditfurth, 1921-1989, is regarded as the most significant science journalist of post-war Germany. His books have reached bestseller status.
