In this book, for the first time, we tried to prove that consciousness obeys the laws of chemistry. We have shown that all physiological processes occurring in the brain - emotions, feelings, memory and others - in the brain have a chemical nature. All aspects of our psyche, including the highest ones, such as morality, have a completely material neurophysiological basis. We argue that even the most "highest" manifestations of our psyche, such as morality, have a completely material chemical basis; that the corresponding psychological mechanisms arose as a result of biological evolution.
