Ned Block described Siegel's The Contents of Visual Experience as "one of the most significant books in philosophy of mind for many years.
"[8] James Genone hailed The Contents of Visual Experience as "an important contribution to the contemporary literature on the nature and structure of perception," and lauded Siegel for being one of the first recent philosophers to challenge the prevailing view that perceptual experiences have representational contents, suggesting that if Siegel is correct in her views, the result would be a sea change that would effect not only the philosophy of perceptual experiences, but also have broad implications for many other areas of philosophy.
[6] Having established this framework, Siegel uses it to examine three major philosophical points: first, that humans are able to determine content from sensory cues (in what Siegel describes as 'the method of phenomenal contrast,") second, that the method of phenomenal contrast supports the idea of the Rich Content model as an enhancement over the Content model, and lastly that while ordinary visual experiences involve seeing things that pertain to objects in addition to seeing things that do not pertain to objects, hallucinations differ from standard visual experiences by only perceiving things that do not pertain to particular objects.
