Argument by Proof

It is not the case that mental properties are reducible to physical properties

This is an argument against eliminativism. It would be more compelling with colored text but I hope the intuition carries. Since we are disproving the identity theory of the mind we ought to adopt the thought that properties of our brain (including sight) are mental properties as the context for this argument.
