What is a Human Being? When we think of ourselves, we think primarily of our subjective sense of self, our Consciousness, and how does it relate to our Body? Are Mind and Body one and the same thing, Monism, or two separate things, Dualism. This is the "Mind-Body Problem." It is the scientific question of how Consciousness is manifest in the structure of Brain. It is the moral questions regarding abortion and end of life. The answers require an explanation in terms of physics, metaphysics, and history. It is the discussion inside those explanatory fields that has built the gulf between popular intuitive Dualism and the expert Monism. This work presents a clear scientific Dualist model, Mind and Body, as two separate things to answer the question, 'What is a Human Being?'
