This is not a pipe

René François Ghislain Magritte (21 November 1898 – 15 August 1967) was a Belgian surrealist artist. He became well known for a number of witty and thought-provoking images. His intended goal for his work was to challenge the observer's preconditioned perceptions of reality and force the viewer to become hypersensitive to their surroundings.

Magritte's work frequently displays a juxtaposition of ordinary objects in an unusual context, giving new meanings to familiar things. The representational  use of objects as other than what they seem is typified in his painting, The Treachery of Images (La trahison des images), which shows a pipe that looks as though it is a model for a tobacco store advertisement. Magritte painted above the pipe "This is not a pipe" (Ceci n'est pas une pipe), which seems a contradiction, but is actually true: the painting is not a pipe, it is an image of a pipe. It does not "satisfy emotionally" — when Magritte once was asked about this image, he replied that of course it was not a pipe, just try to fill it with tobacco.
