Carlo Rovelli has spent his career doing something most physicists quietly avoid: using the technical vocabulary of quantum gravity to make claims about how to live and what things are. On the Equality of All Things is his most direct attempt yet, structured as six lessons that move from relational quantum mechanics through process ontology to a conclusion about human kinship with the physical world. It is serious philosophy, not pop science dressed in equations. The core argument is Rovelli's theory of relational quantum mechanics, where physical systems have properties only relative to other physical systems — not in themselves. From this he derives a broader ontology: no fixed foundation, no things-in-themselves, only processes and perspectives all the way down. A stone is a process. Time passes at different rates in different places. Our partial, perspectival knowledge is not a defect but the basic structure of reality. The move from physics to philosophy is explicit and unapologetic. What separates Rovelli from the cottage industry of oneness literature — the Merlin Sheldrakes, the Robin Wall Kimmerers, the Robert Macfarlanes — is that he is not using science decoratively. He is not saying 'and quantum physics agrees.' He is saying the physics is the argument. Relational quantum mechanics is not a metaphor for interconnection; it is a formal physical theory that, if correct, has metaphysical consequences. The book's intellectual honesty lives in that distinction. Translator Simon Carnell — himself a poet — keeps the prose clean and precise, which matters enormously given how easily this material tips into mysticism. Rovelli is aware of the danger: he explicitly distinguishes his position from new age conjecture, and his aside about 'consciousness' having replaced 'soul' not because it is more rigorous but only because it sounds more scientific is one of the sharpest observations in the book. He is wry about the limits of Enlightenment rationalism without abandoning empiricism. The honest limitation is the loop quantum gravity sections. The reviewer admits to steam coming off the brain, and this is not false modesty — the sections on the granularity of spacetime are genuinely inaccessible without more scaffolding than Rovelli provides. This is not a fatal flaw; the book works as philosophy without full command of the physics. But it means some readers will be taking Rovelli's word for it on the technical load-bearing elements, which is a different reading experience than the book seems to promise. If the physics is the argument, the reader who cannot follow the physics must trust rather than verify.
