Summary

In this chapter, the definition of visual illusion is challenged by studying some known and new phenomena, by demonstrating the perceptual complexity of the notion of visual illusion, and by highlighting its inner attributes. Through a phenomenological analysis at least two different levels of vision and ways of seeing are demonstrated as related to the perception of the illusion and to the perception of the illusoriness. While the perceptual/cognitive notion of visual illusion is necessarily related to the presence of a mismatch between physical and phenomenal domains, the illusoriness is instead an independent perceptual attribute emerging from a multiplicity of visual outcomes within the same stimulus pattern, not necessarily related to the presence of a mismatch, and perceived in itself as related to a sense of strangeness, deception, singularity, mendacity, and oddity.
