Our book reviewed today is Gaia Alchemy by Dr. Stephan Harding. This is such an interesting read. It’s a beautiful blend for someone who has a strong scientific background, but is seeking deeper, symbolic meaning in life. If you read the book—or catch my interview with Stephan in the next session—you’ll find that he brings together a web of scientific, alchemical, and psychological ideas in a way that’s both accessible and profound.
“The seven stages of transformation are not only within you—they shaped the Earth itself.”
Dr. Harding is the co-founder of Schumacher College and was a close friend of James Lovelock, the father of Gaia Theory. This connection threads throughout the book, offering a unique perspective: not from a career occultist or esoteric historian, but from a scientist who stumbled into mystery through personal therapy and the unconscious.
He began this exploration with a Jungian analyst, uncovering archetypes and symbols emerging from his own depths. What started as inner healing evolved into an intellectual and spiritual journey—driven by what he describes as an archetypal possession. Coming from the scientific method, Harding sought to measure, verify, and examine each insight with rigor.
The book begins with how science meets alchemy—a bridge through psyche and symbol. From there, he explores Descartes, the split between inner and outer worlds, and the suppression of psyche in the rise of materialism. But what’s truly fascinating is how Descartes’ dreams still reflected unconscious wisdom—proof that psyche never disappears, even from the rationalist.
Harding introduces archetypes like the unus mundus, the undivided reality behind psyche and matter. He begins correlating scientific processes like carbon cycles with the classical alchemical stages, culminating in what he calls the GaiaScope. This is a contemplative model that fuses science, alchemy, and Jungian psychology into one system of internal and external reflection.
The GaiaScope introduces a seven-stage system modeled after the classical alchemical process: calcination, dissolution, separation, conjunction, fermentation, distillation, and coagulation—correlated with lunar and planetary cycles. He then maps these stages to the formation of the Earth, atmosphere, and biosphere, offering us a macro-microcosmic understanding of alchemy.
One particularly fascinating insight is his exploration of Isaac Newton. Harding uncovers Newton’s extensive collection of alchemical texts, showing how even a foundational figure in modern physics had one foot in the mystical. While it’s unclear whether Newton saw this through a spiritual lens, Harding points out that even scientific engagement with symbolism creates space for inner transformation.
Harding’s writing is grounded—there are no wild metaphysical leaps here. Instead, you’re offered a methodical and poetic journey through self and system, rooted in Gaia, in the psyche, and in science. As someone who practices alchemy, Jungian work, and spiritual ecology, I found this a deeply nourishing text.
He outlines the Jungian model—ego, four functions (linked to the elements), the personal unconscious, and the archetypal collective unconscious—and builds from there. The GaiaScope helps one apply these models in practical reflection. Even more interesting is the dialog format he includes with a scientific colleague, which humanizes and balances the heady material.
This book is highly recommended for seekers of integration—those looking to understand the alchemical self, not just as metaphor, but as a living ecology, rooted in Earth’s unfolding story. If you love Jung, love Lovelock, and seek to root spiritual practice in planetary responsibility, this is a must-read.
