The knowledge argument - and the inadequacy of scientific knowledge

Recently a number of authors have responded to the knowledge argument by suggesting that Mary could learn about new physical facts upon release (Flanagan, 1992; Mandik, 2001; Stoliar 2001; Van Gulick, 1985). A key step in achieving this is a demonstration that there are facts that can be known via colour experience that cannot be learnt scientifically. In this paper I develop an account of scientific and visual knowledge on which there is a difference between the knowledge provided by science and that provided by vision.
