On the Equality of All Things: Lessons on Physics and Philosophy by Carlo Rovelli

from $10.80
Hardcover:

A radical new vision of reality from one of the great minds of our time, mapping a watershed moment in both physics and philosophy.

“Carlo Rovelli is the best thinker out there articulating physics, philosophy, and literature. There simply are no scientists of his caliber who also are humanists of the first order. His prose has the enviable ability to expand the realm of the utterable and, with it, the reach of our intellectual experience.” —Hernan Diaz, Pulitzer Prize–winning author of Trust

We are living in an age of scientific advancement on par with that of Copernicus, Galileo, and Newton: a period of discovery that has so fundamentally revolutionized our understanding of the world that it has shaken our most basic assumptions about who we are and our relationship to all things. In On the Equality of All Things, Carlo Rovelli turns his attention to this reckoning, bringing expertise and clarity to both the most mind-bending theories of modern physics and the most fundamental questions imaginable about the nature of time and existence.

Drawing from the latest advances in science and the teachings of modern and ancient philosophers, Rovelli invites us into the universe we thought we knew—one that is not made of things but of relationships. Time is a string of events, and there is no present time in the universe. Cause and effect are an illusion, and reality is an intricate and fragile web. And knowledge itself will always be imperfect, impermanent, and incomplete.

This is an awe-inspiring meditation on science, meaning, and being that charts the strange majesty of the world we've always lived in—from a thinker unafraid to challenge not only centuries of philosophers but our own intuitions about the nature of reality and what organizes it.

  • Carlo Rovelli is an Italian theoretical physicist whose work on loop quantum gravity has made him one of the most widely read scientists alive — his books, including Seven Brief Lessons on Physics, The Order of Time, Helgoland, and White Holes, have sold in the millions and been translated into more than fifty languages. He's been named among Foreign Policy's 100 most influential global thinkers and Prospect's top fifty thinkers, and he's held research and teaching posts in Italy, the United States, Canada, and France before settling in Spain. On the Equality of All Things continues the project that made him famous: explaining the strangest ideas in physics without losing the reader — or the wonder.

  • Critics and fellow bestselling authors are calling it elegant, lucid, and clear:

    • "Carlo Rovelli is the best thinker out there articulating physics, philosophy, and literature..." — Hernan Diaz, Pulitzer Prize–winning author of Trust

    • "In clear, elegant prose, Rovelli guides the reader through a whirlwind tour..." — The New York Times Book Review

    • "One of the warmest, most elegant and most lucid interpreters..." — The Wall Street Journal

    • "A convincing call to embrace 'radical uncertainty.'" — Kirkus Reviews

This book is for you if

  • You loved Seven Brief Lessons on Physics or The Order of Time and want more of Rovelli's plain-spoken physics.

  • You're curious how quantum theory and ancient philosophy end up circling the same questions about reality.

  • You want a short book — 192 pages — that rewires how you think about time, not a semester-long textbook.

  • You're drawn to the idea that the universe is made of relationships rather than things, and want that argument made rigorously.

  • You enjoy science writing that reads as much like a meditation as an explanation.
