  Such a reading would of course increase the plausibility of the claim that a conscious state's representational properties exhaust its mental properties but at the cost of significantly weakening or even trivializing the thesis. Thus the representationalist seems to need an interpretation of representational sameness that goes beyond mere satisfaction conditions and reflects all the intentional or contentful aspects of representation without being sensitive to mere differences in underlying non-contentful features of the processes at the realization level. Thus most representationalists provide conditions for conscious experience that include both a content condition plus some further causal role or format requirements (Tye 1995, Dretske 1995, Carruthers 2000). Other representationalists accept the existence of qualia but treat them as objective properties that external objects are represented as having, i.e., they treat them as represented properties rather than as properties of representations or mental states (Dretske 1995, Lycan 1996).
