 Pautz (2017) points out that there are restrictions on sensory appearances that have no parallel for other intentional states such as beliefs. For example, a surface cannot appear both round and square, or both pure red and pure yellow at the same place at the same time; nor can anything seem round or red but not extended. Pautz contends that such impossibilities are metaphysical in strength. In contrast, there is nothing metaphysically or even nomologically impossible, but only irrational, about contradictory or otherwise anomalous beliefs or desires. How is a representationalist to explain the existence of such laws?
