Physics and Free Will: The Science of Libertarian Freedom

Can libertarian free will survive our best physical theories? While prominent physicists argue that genuine agency contradicts science, this book demonstrates that contemporary physics actually provides robust foundations for human freedom. Physics and Free Will rigorously navigates the complex intersection of physical theory and the free will debate. Koperski begins by clarifying determinism’s scientific foundations before systematically addressing challenges from special relativity and refuting physics-based arguments against mind-body dualism. Drawing on insights from continuum mechanics and condensed matter physics, he reveals how multiscale systems exhibit the emergence of causally efficacious properties irreducible to their micro-constituents. Using these insights, Koperski develops a framework that preserves libertarian intuitions about genuine choice while remaining consistent with physical theory. Through meticulous examination of determinism, reductionism, and the causal closure of physics, this comprehensive work reveals how contemporary science’s recognition of emergent causation provides ample space for genuine human agency. This book will be essential for researchers and graduate students in metaphysics, philosophy of physics, philosophy of science, and philosophy of mind, and for anyone seeking to understand how contemporary science reshapes rather than eliminates the possibility of free will.
