 Another response to this potential problem revises the thesis of representationalism, construing the representational properties that determine phenomenology as attitude-content complexes rather than contents alone. For example, Chalmers 2004 distinguishes pure representational properties—the property of having a certain content—from impure representational properties—the property of having a certain content represented in a certain way. Examples of impure representational properties include the property of having a certain content represented in modality M, and that of having attitude A to a certain content. Impure representationalism is then the thesis that impure representational properties determine phenomenology, so that any two experiences with the same impure representational properties have the same phenomenology. This position allows that experiences in different modalities, or experiences that instantiate different attitudes, could have the same content, yet differ phenomenally because, say, one is visual and the other kinesthetic. For instance, perhaps both represent that one’s hand is moving, or that something is round. Versions of impure representationalism are held by Lycan 1996, Chalmers 2004, 2006, Pautz 2010.
