The Hard Problem and Theories of Consciousness

Survey the central debates in consciousness studies: the hard problem and the explanatory gap, the major philosophical responses, and the leading scientific theories of consciousness. You'll compare physicalism, illusionism, panpsychism, and dualism; learn the aims of global workspace, integrated information, higher-order, and predictive processing theories; and evaluate what phenomenology contributes to these debates. You'll finish able to read current consciousness research critically and place new claims within the field.
