Freedom has long been a foundational concept at the heart of our civilization. Free markets, free media, free speech—even in these politically divided times, freedom is one thing we can all agree on. But we also live in a time of unprecedented economic inequality, eroding democracy, and a broken criminal justice system. How can we value freedom and simultaneously inhibit it? In , Raoul Martinez argues that the more we understand the limits on our freedom, the better we will be at resisting them. Drawing on neuroscience, criminology, psychology, politics, climate science, economics, and philosophy, lays a blueprint for us to make sense of our fractured world—and illuminates the path toward a better future.
