On the heels of winning this year's Pulitzer prize for poetry, W.S. Merwin joins Bill Moyers for a wide-ranging conversation about language, his writing process, the natural world, and the insights gleaned from a much-lauded career of more than 50 years. W.S. Merwin is the author of 21 volumes of poetry and won his second Pulitzer Prize for his most recent collection, THE SHADOW OF SIRIUS.
