In this major new work, John Searle launches a formidable attack on current orthodoxies in the philosophy of mind. More than anything else, he argues, it is the neglect of consciousness that results in so much barrenness and sterility in psychology, the philosophy of mind, and cognitive science: there can be no study of mind that leaves out consciousness. What is going on in the brain is neurophysiological processes and consciousness and nothing more - no rule following, no mental information processing or mental models, no language of thought, and no universal grammar. Mental events are themselves features of the brain, "like liquidity is a feature of water."
