Lycan's Layering Thesis

According to William Lycan's 'Layering Thesis', perceptual experiences often have multiple, hierarchically-ordered contents, so that more complex properties are perceptually represented in virtue of the perceptual representation of simpler properties. I raise some questions about the Layering Thesis and the work that is asked of it in Perceptual Content. Specifically, I consider whether the Layering Thesis allows us to make progress in the debate over which properties can be represented in perception, as well as what it can tell is about the content of touch and taste. I also ask whether one needs to endorse Representationalism in order to accept the Layering Thesis.
