Abstract

Jackson has ellaborated an argument to show that our experiences or qualitative states gather information which cannot be obtained in any other way. Functionalists reject in many ways that experience may bring new information. The point of this paper is to argue that, if func-tionalism is right, if experiences or "qualia" are not informative, then functionalism cannot report about them. The functionalist criticism of Jackson's argument makes it impossible for any functionalist theory to know experience.
