Editing Knowledge argument (section)

=== Refutation of physicalism ===
Jackson argues further, saying that if Mary does learn something new upon experiencing color, then [[physicalism]] is false. Specifically, the knowledge argument is an attack on the physicalist claim about the completeness of physical explanations of mental states. Mary may know everything about the science of color perception, but can she know what the experience of red is like if she has never seen red? Jackson contends that, yes, she has learned something new, via experience, and hence, [[physicalism]] is false. Jacks<ref name="p130">{{Harvnb|Jackson|1982|p=130}}</ref>
