Literary statements that are false as mathematics I recently wanted to use
the title of the famous short story
"Everything that Rises must Converge"
in a poem of mine.
However, the mathematician in me
insisted on changing it to
"Everything that Rises, if the rise is bounded, must Converge".
Are there other literary quotations
that are false mathematically,
and how can they be changed to make them true?
Note:
Attempts to use
"To be or not to be"
will be dealt with
most severely.

As I noted 
some years ago, an example is the claim by Thomas Carlyle (1795$-$1881, 
in Sartor Resartus (c.1833)) that "It is a mathematical fact that 
the casting of this pebble from my hand alters the centre of gravity 
of the universe."  In fact, this echo of John Donne's 
"if a clod be washed away by the sea, Europe is the less"
[Meditation XVII, 1624]
is not a fact of mathematics but an error in physics according to
Newton's Laws (1687): the recoil must exactly cancel out the pebble as the
"centre of gravity of the universe" continues on its unalterable course.
[Later] Proposed correction: "It is a mathematical fact that
the casting of this pebble from my hand moves the centre of gravity
of the Earth."
