The great enemy of poetry in the Romantic tradition has never been reason, but rather those premature modes of conceptualization that masquerade as final accounts of reason in every age. It is not reason that menaces the shaping spirit, but the high priests of rationalization, the great men with the compasses who have marked out circumferences, from Descartes, Bacon, Newton, and Locke down to subtler limiters of the imaginative horizon in Hegel, Marx, Freud, and their various revisionist disciples. Romanticism, in what seems its central tradition, at least in our language, is a revolt not against orderly creation, but against compulsion, against conditioning, against all unnecessary limitation that presents itself as being necessary.
—Harold Bloom, The Ringers in the Tower (1971)
