René François Ghislain Magritte (1898-1967) was a Belgian surrealist artist. He was famous for his witty and thought-provoking images. His work challenges preconditioned perceptions of reality.  His painting, The Treachery of Images, shows a pipe, with words painted below: "Ceci n'est pas une pipe" - "This is not a pipe."  He was making the point that it is in fact a painting of a pipe, not a pipe itself, and is therefore unable to "satisfy emotionally" as a pipe can.  When asked about the image, he said of course it is not a pipe -- just try to fill it with tobacco.
