The world disclosed by the physical sciences can seem depressing. Modern physics, for example, has undermined the religious idea that the universe has a spiritual dimension. Quantum physics in particular seems to present the world as more paradoxical than rational. Is there room within – or in addition to – the world presented to us by the physical sciences for ideas such as freedom, dignity, justice, and even God? Or should these all be regarded as useful illusions?
