David Lewes

David Lewis was a prominent philosopher known for his work on modal realism and physicalism. Physicalism is the view that everything that exists is physical, meaning that everything can be explained in terms of physical processes and entities. Lewis argued that all mental states and experiences arise from physical states in the brain. His ideas emphasized that even abstract concepts, like possible worlds, are rooted in the physical world. While some question the implications of his views for understanding consciousness, Lewis significantly shaped discussions around the relationship between mind and matter, advocating that everything, including thoughts and feelings, can be understood physically.
