The Problem of People in Lyric Poetry

Working on an essay that situates my lyric poems into the broader concerns of lyric poetry. I'm writing about the relationship between poet and people and how (the issues surrounding relationships with) people appear in and behind lyric poetry, though they are ultimately filtered through the poet's self and experience. Anyway, found the best passage ever from Sylvia Plath's Unabridged Journals (of course I would quote Sylvia Plath) to support my personal ars poetica, and now I will share with you:

I love people. Everybody. I love them, I think, as a stamp collector loves his collection. Every story, every incident, every bit of conversation is raw material for me. My love's not impersonal yet not wholly subjective either. I would like to be everyone, a cripple, a dying man, a whore, and then come back to write about my thoughts, my emotions, as that person. But I am not omniscient. I have to live my life, and it is the only one I'll ever have. And you cannot regard your own life with objective curiosity all the time.
