Percezioni, ragionamenti e illusioni

Abstract

Common sense tends to believe in the existence of optical and perceptual illusions but it hardly supports the thesis of an illusory reasoning. In the psychology of reasoning, one rather talks of errors of reasoning that experience can fix and change. For this reason, over the years, the belief that there is a clear distinction between optical and perceptual illusions has been reinforced. The former would be stronger, the latter weaker and correctable. In this paper I intend to demonstrate, through the presentation and analysis of a topology of illusions, that there is indeed a universal structure underlying every kind of illusion. This same structure allows us to talk about a universal criterion to identify illusions: a key part of the outside world.
