Black Spring:

"I also think that O'Hara is one of the most remarkable poets of the human spirit the English/American language will ever know. And I believe he is also one of the most remarkably "psychologically sophisticated" and "emotionally mature" poets we will ever know. Much more so than, again, say, Creeley, who is oft-revered, and rightly so, for his "sincerity" and for his capacity for revealing depths of "vulnerability" and "honesty" and "courage" (emotional courage, I guess that would be) that are so blatantly and shamefully "covered up," repressed, pounded back down into the collective Unconscious of the nation's overall cultural "maturity." I also think that half a generation or so later, David Bromige and Rae Armantrout are O'Hara's heirs and continue to go even further (I'm talking "emotional maturity" and "psychological sophistication" here, now, NOT form, style, technique, method, etc.), though the "notes" O'Hara hits are surely singularly spectacular, no mistaking that."

That's a fascinating avenue of approach: what, for example, is the status of "sentimentality" in O'Hara and Creeley?
