This, because the French word for hawk is "faucon"
(falcon), which sounds like "false cunt". Hence Duchamp's conclusion...
Where may be seen that by doing this, he added
a bit to "This is not a pipe" by Magritte.
As a matter of fact, Duchamp's conclusion adds
perspective to what Magritte fingers. Because Courbet's work, of course,
is not the true cunt either. So that the hawk says "false cunt" just as
Courbet's work should say "false cunt" to any viewer. And so that ordinary
perspective itself is also fingered as a lie.
But the movement introduced by Duchamp's play
on words fingers that our representation is, as regards reality, in the
same relationship as words in a play on words. That is, not much more than
a chance, or more precisely said, in the best cases, a coincidence.
