This work investigates the dual nature of Isaac Newton, questioning how his pursuit of alchemy and the occult informed his foundational contributions to modern science. Michael White, a science writer and biographer, utilizes historical records and Newton's private papers to construct a portrait of a man caught between the medieval tradition of alchemy and the emerging rigor of the scientific revolution. The book argues that Newton's obsessive, secretive nature was not a distraction from his scientific work, but rather a driving force behind his quest to decode the fundamental laws of the universe.

Experts and readers often note that this text provides a necessary humanizing counter-narrative to the traditional image of Newton as a purely rationalist figure. While some scholars debate the extent of alchemy's influence on his physics, the book is widely regarded as a compelling entry point for those interested in the intersection of science and mysticism.
