The gash in its throat was shocking, but not pathetic. - Ted Hughes

The deeps are cold:
In that darkness camaraderie does not hold:
Nothing touches but, clutching, devours.

Sylvia went furthest in the sense that her secret was most dangerous to her. She desperately needed to reveal it. You can’t overestimate her compulsion to write like that. She had to write those things — even against her most vital interests. She died before she knew what The Bell Jar and the Ariel poems were going to do to her life, but she had to get them out. She had to tell everybody . . . like those Native American groups who periodically told everything that was wrong and painful in their lives in the presence of the whole tribe. It was no good doing it in secret; it had to be done in front of everybody else. Maybe that’s why poets go to such lengths to get their poems published. It’s no good whispering them to a priest or a confessional. And it’s not for fame, because they go on doing it after they’ve learned what fame amounts to. No, until the revelation’s actually published, the poet feels no release. In all that, Sylvia was an extreme case, I think.

The danger, I suppose, of using pseudonyms is that it interferes with that desirable process—the unification of the personality. Goethe said that even the writing of plays, dividing the imagination up among different fictional personalities, damaged what he valued — the mind’s wholeness. I wonder what he meant exactly, since he also described his mode of thinking as imagined conversations with various people. Maybe the pseudonyms, like other personalities conjured up in a dramatic work, can be a preliminary stage of identifying and exploring new parts of yourself. Then the next stage would be to incorporate them in the unifying process. Accept responsibility for them. Maybe that’s what Yeats meant by seeking his opposite. The great Sufi master Ibn el-Arabi described the essential method of spiritual advancement as an inner conversation with the personalities that seem to exist beyond what you regard as your own limits . . . getting those personalities to tell you what you did not know, or what you could not easily conceive of within your habitual limits. This is commonplace in some therapies, of course.
