This perspective is known as physicalism. It posits that all mental events and processes can be ultimately explained by physical processes in the brain and nervous system. Physicalism is a key view in contemporary philosophy of mind and cognitive science.

Materialism or physicalism.

Materialism is linked to the theoretical approach of physicalism, which posits that everything that exists is physical in nature and can be explained by physical processes. Materialism asserts that the world is made up of material components and denies the existence of any supernatural entities or forces.

Physicalists believe that mental states are ultimately reducible to physical states in the brain. They argue that by studying the physical processes of the brain, we can explain all aspects of consciousness and mental phenomena without the need for any separate non-physical substances. This solution, known as "reductive physicalism," seeks to bridge the gap between the physical and mental worlds by reducing mental properties to physical properties.
