Text in English and Danish. A persistent theme of the 20th century has been a critique of metaphysics. But the limitations of this critique are manifesting themselves more and more clearly. Among them is the fact that both inner and outer nature have form and structure. Philosophy of nature becomes unavoidable. The lifeworld of man cannot be thoroughly understood without metaphysical reflection. The theme of this volume is the metaphysical questions about man and nature and the relationship between them, as these questions emerge in the human lifeworld beyond the critique of metaphysics of the 20th century. The contributions provide a comprehensive elucidation of the theoretical and practical problems of metaphysics. They range from the metaphysics of the ecological crisis and the concept of progress to the nature of man and the foundation of science in the human lifeworld.
