[Man] asks from prose, only under a more obscure and indefinite form, what he expects from poetry; and indeed, where is the actual boundary between poetry and prose? and how can one help owning that prose is but poetry gradually but never entirely extinguished or calmed down? – Alexandre Vinet (1797–1847)

Poetry is reverie on paper. – Terri Guillemets, “Quiet time with my soul,” 1998

I would as soon write free verse as play tennis with the net down. – Robert Frost, 1935
