On the Equality of All Things: Physics and Philosophy

by Carlo Rovelli, Simon Carnell (Translator)

What can we really know about the world around us? With clarity and lightness, acclaimed physicist Carlo Rovelli guides us through the speculative depths of modern physics, unafraid to test their limits, not least because, as he suggests, there may be no final ground to reach.

Electrons and minds, stones and laws, judgements and galaxies are not essentially different in nature from one another. They are ideas that illuminate each other. Reality, he shows, is shaped by this continuous play of reflections. From this emerges Rovelli’s central the equality of all things.

Like the ancient Chinese philosopher Zhuangzi, who dreams he is a butterfly and wakes unsure whether he is Zhuangzi dreaming to be a butterfly or a butterfly dreaming to be Zhuangzi, Rovelli invites us to see reality anew, recognizing our knowledge is coherent but also uncertain and circular. We are made of the same stuff as the rest of reality – and so we are, in a deep sense, home in the world.
