Welcome to the Wikiversity learning project about the Nonphysical. What does it mean for something to be nonphysical? How do people come to adopt physicalism (belief that everything that exists is physical) or dualism? (belief that both physical and non-physical things are real) or idealism (belief that only non-physical mental phenomena are real)?

In The Astonishing Hypothesis, Francis Crick wrote, "a person's mental activities are entirely due to the behavior of nerve cells, glial cells, and the atoms, ions, and molecules that make them up and influence them." Is there any reason to believe that mental phenomena can exist independent of a physical system like a brain?
