Prose on certain occasions can bear a great deal of poetry on the other hand, poetry sinks and swoons under a moderate weight of prose. – Walter Savage Landor

[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 the journal of the sea animal living on land, wanting to fly in the air. Poetry is a search for syllables to shoot at the barriers of the unknown and the unknowable. Poetry is a phantom script telling how rainbows are made and why they go away. – Carl Sandburg, Poetry Considered
