Materialism is the view that only matter is real and that everything, including the mind, can be explained through physics and chemistry. It is opposed to idealism and claims that only things that can be observed through the senses or experiments are part of reality. Materialists believe that matter, its motions, and properties make up the ultimate nature of all things and that there is no supernatural or spiritual reality. Modern forms of materialism, like mechanistic materialism, view everything, including humans and thought, as simply matter in motion governed by physical laws, reducing mind to the physical workings of the body. New materialism rejects the idea that everything is based on strict physical laws and direct contact, believing instead that mind and body are identical
