Winner of the 1995 PEN/Martha Albrand Award for First Non-Fiction, Proofs and Theories is an illuminating collection of essays by Louise Glück, whose most recent book of poems, The Wild Iris, was awarded the Pulitzer Prize. Glück brings to her prose the same precision of language, the same incisiveness and insight that distinguish her poetry. The force of her thought is evident everywhere in these essays, from her explorations of other poets' work to her skeptical contemplation of current literary critical notions such as "sincerety" and "courage." Here also are Glück's revealing reflections on her own education and life as a poet, and a tribute to her teacher and mentor, Stanley Kunitz. Proofs and Theories is the testament of a major poet.
