Abstract:
Do illusions exist or are we deluded about the concept? I am going to argue that the concept of illusion is a delusion. Traditionally, we draw a distinction between veridical and illusory perception by saying that in the former case our perceptions correspond with the physical reality whereas in the latter case there is a discrepancy. However, while there might be general agreement on what we perceive in particular circumstances, it is less clear how should we define what is the \u2018physical reality\u2019. It cannot be the \u2018proximal\u2019 stimulus (i.e. the retinal image) because, if it were, all the perceptual constancies would have to be regarded as illusions. Similarly, the \u2018distal stimulus\u2019 cannot be the reality because those situations in which the pattern of light reaching the eye is \u2018projectively equivalent\u2019 to another real world scene (such as the Ames Room or viewing a stereogram) would have to be regarded as illusions. A possible way out of the problem of what constitutes the \u2018reality\u2019 would be to define an illusion as a discrepancy between the information contained in the spatio-temporal patterning of light reaching the eye and what we perceive. But even this definition has problems.<\/p>\n","protected":false},"featured_media":0,"template":"","acf":[],"_links":{"self":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/event\/1875"}],"collection":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/event"}],"about":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/types\/event"}],"wp:attachment":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/english\/wp-json\/wp\/v2\/media?parent=1875"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
