"The Diamond & the Star" is a profound exploration of the symbolic significance of diamonds and stars in philosophy and religion. The author, John Warden, connects the Taoist symbol of the self, the "diamond body," with the geometric shape of the tetrahedron and the four valences of the carbon molecule, which forms the basis of all life. This connection is further examined by highlighting the parallels between the ancient wisdom of Lao Tzu and the symbolism of Jungian psychology. Additionally, the possibility of a visual-oriented approach in science is discussed, which could lead to a new understanding of the world. This book is aimed at readers interested in the intersections of science, philosophy, and Eastern wisdom.
