“Literary history and the present are dark with silences . . . I have had special need to learn all I could of this over the years, myself so nearly remaining mute and having to let writing die over and over again in me. These are not natural silences--what Keats called agonie ennuyeuse (the tedious agony)--that necessary time for renewal, lying fallow, gestation, in the natural cycle of creation. The silences I speak of here are unnatural: the unnatural thwarting of what struggles to come into being, but cannot.”
