Aporia

Definition:
Aporia means to be at a loss, doubt,
or an internal contradiction in a text, argument, or theory. This device is
commonly seen in rhetorical questions where the author is questioning oneself
and swaying between two or more ideas, exercising uncertainty.  It can also be described as a state of
puzzlement in philosophy and in rhetoric, a state of doubt.
Literary Example:
“To be, or not to be: that is the
question.
Whether ‘tis nobler in the mind to
suffer
The slings and arrows of outrageous
fortune,
Or to take arms against a sea of
troubles,
And by opposing end them? To die: to
sleep;
Than fly to others that we know not
of?
Thus conscience does make cowards of
us all.….” -Hamlet
