A term introduced in or shortly before 1832 by the French alienist Jean-Etienne Dominique Esquirol (1772-1840) to denote an "illusion that has a bearing on one or more objects present in the external world. Esquirol uses the term in opposition to the term " ganglionic illusion, a notion that he reserves for illusions arising as a consequence of stimuli from inside the body. Illusion of the senses is conceptually compatible with Kandinsky's notion of "sensory misperception.
