| Abstract: | Although philosophers have often insisted that specular perception is illusory or erroneous in nature, few have stressed the reliability and indispensability of mirrors as optical instruments. The main goal of this paper is to explain how mirrors can contribute to knowledge and at the same time be a source of systematic errors and misleading appearances. To resolve this apparent paradox, I argue that mirrors do not generate perceptual illusions or misperceptions, by defending a view of mirrors as transparent and invisible visual media. I then consider the reasons for which mirrors are said to be misleading. Contrary to the illusory account, I defend a nonperceptual approach to the errors attributable to mirrors, which analyses the kind of errors generated by the use of mirrors in terms of false judgments. I further show that a nonperceptual view of errors extends to all of the cases in which a sensorimotor adaptation is required, such as perception through magnifying or inversing lenses. |
