 Both Galileo and Descartes were aware that the medial account was revisionary relative to a common sense view of sounds, or at least as revisionary as is the sensation view. Sounds for the wave view or the sensation view are not what we unreflectively take them to be on the basis of the content of auditory perception. (Indeed, Galileo himself endorsed both a proximal theory—sounds as sensations—and a medial theory, thereby possibly originating a dualist account.) At the same time Galileo and Descartes, as well as other modern philosophers, were not particularly keen in detailing the phenomenological content of auditory perception.
