last possible domain

[Poetry] is the last possible domain in which we could preserve by language what we commonly deem to be reliable cognitive commonplaces, and last to appeal to solid, everyday perceptions. Poetry does not seek to negate these props. But it uncovers the oppressions of naïve experience and the stale pool of confirming constancies.
