Philosophy of mind is a branch of
philosophy that studies the nature of the
mind,
mental events,
mental functions,
mental properties,
consciousness, and their relationship to the physical body, particularly the
brain. The
mind–body problem, i.e. the relationship of the mind to the body, is commonly seen as one key issue in philosophy of mind, although there are other issues concerning the nature of the mind that do not involve its relation to the physical body, such as how consciousness is possible and the nature of particular mental states.
