It is not a pipe. It is not tobacco. It is not a match. It is not smoke. It is not smoking. It is not a man smoking. It is not a painting of a pipe. It is not oil on canvas. It is not paint at all. It is not an image. It is not three-dimensional. It is not two-dimensional. It is not brown. it is not black. It is not a bowl of smooth wood. It is not a curved stem. It is not readily at hand. It is not to be bought or sold. It is not an object of desire. it is not an object of perception. It is not not. It is not. Ca n'est pas quelque chose. It is. Not. It is naught. It is not to be trusted. It is no man's art. It.
On Magritte's painting of a pipe titled "Ceci n'est pas une pipe." (This is not a pipe.)
