Frank Jackson and Physicalism

Frank Jackson begins his article by writing about what he feels to be a fatal flaw in physicalism. He writes a story about a girl named Mary who is raised in a black-and-white room. In this room Mary was taught everything there is to know about the physical world. The only catch is she learned only from media, which was black-and-white, so she knows nothing of the colors outside this room. After learning everything about the physical world, she is then given the chance to see color. She will then "learn" what color is in the world. For this reason Jackson believes physicalism to be false.
Jackson contends that if physicalism were true, Mary would know what a color looks like before she would ever see that color. This, however, is false since Mary could not possibly know what the color looks like before exposure to it. It is impossible for any person to imagine what a color looks like before they see any color at all. Jackson writes, "imagination is a faculty that those who lack knowledge need to fall back on."
Another argument against physicalism posed by Jackson is that any knowledge Mary did not have upon seeing color for the first time is the knowledge about the experiences of others. The problem with this for physicalism is that fact Mary would realize how mistaken her knowledge of other's conceptions has been. Even though Mary would have known all of the neurological processes in a person's mind, she would not have known the person's actual experience involved in the process. There would also be facts she did not know about objects, but she would know all physical facts about them. For this reason it is not any experience the object may have, but a fact about the object itself.
In the article the main point seems to be the fact that,...
