Evaluating materialism

- Neuroscience - we know which parts of the brains are responsible for language, memory and emotions

- The problem of interaction - how can a non-physical mind interact with a physical body

- Category error - Gilbert Ryle - argues that belief that there is a separate soul is a category mistake

- simplicity - materialists argue that consciousness being explained by physical and material events in the brain is the simplest explanation.
