Context

"I dwell in possibility" is the opening line of Emily Dickinson's poem by the same name. (She didn't title her poems, actually, so we usually just call them by their first lines.)

One way to read the line is that Possibility = poetry. After all, why else would she be comparing it to prose? It seems like she's implying that poetry is better than prose because poetry has more possibilities: it opens up the mind more and is less concrete than prose. 

Them's fightin' words.

Where you've heard it

Poets the world around will claim the superiority of poetry over prose, and plenty of people will dare to disagree.

Seems like a light enough debate, but it's been known to be fatal in some parts. No joke. 

Pretentious Factor

If you were to drop this quote at a dinner party, would you get an in-unison "awww" or would everyone roll their eyes and never invite you back? Here it is, on a scale of 1-10.

We guess it depends in which kind of possibility you're dwelling in—lowercase P or capital.
