Abstract

While a necessary condition for perceiving a physical object is that the object cause the perceiver to undergo a sense experience, this condition is not sufficient. causal theorists attempt to provide a sufficient condition by placing constraints on the way the object causes the perceiver's experience. i argue that this is not possible since the relationship between a perceiver's experience and an object in virtue of which the perceiver perceives the object does not supervene on any of the ways in which the object causes the perceiver's experience
