Introduction to the philosophy of mind

What is the mind? Is it something different from the body? And if so, what is this thing we call mind? What is wrong with the mind being the brain? How does the mind represent things? How does a person know his internal states, such as pain? What is consciousness? Can it be reduced to events in the brain? These questions have preoccupied philosophers throughout the ages, because they are closely linked to other philosophical branches, such as the theory of knowledge and the philosophy of ethics.
