A public expectation, it has to be said, not of poetry as such but of political positions variously approvable by mutually disapproving groups.
Seamus HeaneyI have always thought of poems as stepping stones in one's own sense of oneself. Every now and again, you write a poem that gives you self-respect and steadies your going a little bit farther out in the stream. At the same time, you have to conjure the next stepping stone because the stream, we hope, keeps flowing.
