 Structural mismatch. Following Hardin (1988) and others, Pautz (2014, 2019) argues that the structural properties of a sensory field, paradigmatically resemblance relations, match the neural substrates of the relevant experiences rather than the chemical or physical properties of the representata. For example, the sensory quality blue resembles purple more strongly than it resembles green, but the reflectances underlying worldly objects are the other way around: the blue reflectance type resembles the green reflectance type more than it does the purple. Even more dramatic mismatches obtain in the case of smell. Therefore, it seems that a sensory quality is a narrow property rather than the wide worldly one predicted by standard externalist psychosemantics.
