The book was published in 1908 and it explores the relationship between science, philosophy, and religion. It argues that science and religion are not separate from each other but rather complementary aspects of the same quest for understanding the world. The book begins with an introduction to the concept of "the third kingdom" which is a metaphor for the realm of pure thought and pure feeling that exists beyond the physical world. This realm is seen as the source of all knowledge and truth and is the ultimate goal of human existence. The author argues that science and religion are both necessary for human progress and that they should be integrated into a single system of knowledge. He also emphasizes the importance of developing a personal paradigm for perceiving the technological process of developing modern knowledge as the basis for the survival of humanity and the unification of people in a warring state. Throughout the book, the author uses examples from various fields such as biology, physics, and philosophy to illustrate his points. He also critiques the dominant scientific and religious beliefs of his time, arguing that they are based on incomplete or inaccurate assumptions about the nature of reality. The book concludes by emphasizing the need for a new kind of thinking that combines the best of science and religion to create a more complete and accurate understanding of the world.
