Carlo Rovelli, Quantum Physics, Relationalism, Interaction, Anti Realism.
Rovelli gives a perfect description of what philosophers class as anti-realism. Oddly enough, he uses the words of Democritus to do so). Rovelli writes: “Democritus gave a strange definition of ‘man’: ‘Man is what we all know.’” This appears to be a poetic expression of philosophical anti-realism.
