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.
“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
