"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....
Dualism and monism are the two major schools of thought that attempt to resolve the mind–body problem. Dualism can be traced back to the Sankhya and Yoga schools of Hindu philosophy, and Plato,but it was also formulated by René Descartes in the 17th century.Substance dualists argue that the mind is an independently existing substance, whereas property dualists maintain that the mind is a group of independent properties that emerge from and cannot be reduced to the brain, but that it is not a distinct substance"
