Abstract
The traditional definition of perceptual illusion is critically discussed. To avoid the theoretical limitations of a definition which includes the opposition of the physical versus perceptual domain, a phenomenological definition is proposed which seems to include all possible cases of what usually is intended for perceptual illusions. Some relevant theories about object identity are mentioned and the concept of illusion is confronted with that of phenomenal reality (Michotte). Few examples are given of the different kinds of illusion which can be perceived as a function of the object identity
