Beginning with an essay on the history and theory of poetic argument, he traces its patterns through Romantic and Modernist literature. He divides his subject into three areas: the paradoxes of reason, language, and argument. Poetic Argument surveys the writings of the five poets in light of what has to be "e;proved"e; and identifies the characteristic styles of proof for each. For example, in the chapter on Marianne Moore, Kertzer studies two expressions of poetic argument. The first regards poetry as a waking dream, combining the powers of sleep and calculation. The second, derived from Imagism, treats poetry as a special way of seeing. Kertzer suggests that the combination of these two elements produces Moore's characteristically intricate, but inconclusive, forms of argument.
