Criticisms of Materialism
Change of Reduction
A complete physical description of a person will miss out crucial parts of being human.
Mary's Room example -
Black and white world but can understand Red. Even though she's never seen it. She's missing out the experience of red.
If we're entirely physical, there's no room for free will.
It's an illusion (hard determinism)

The problem of interaction.
