Helen Vendler has been one of the most prominent poetry critics over the past 40 years. “Whole sectors of the poetry world have complained about the limits of her sensibility. She doesn’t like experimentation, one complaint goes. Her attitude toward poetry is too academic, says another. At the same time, somewhat paradoxically, literary scholars often consider Ms. Vendler far out of touch with their profession. Her approach is, so to speak, rigorously untheoretical: A poem speaks to her, or it doesn’t, and the critical essay is Ms. Vendler’s preferred medium of reply.”
