Billy Budd concentrates Melville's philosophy of war and lifts it to its highest point of development. The themes of the work extend ideas he had developed since his youth, and its poetic conceptions are the offspring of earlier ones expressive of his thought on “the greatest of evils.” In Billy Budd the philosophy is conveyed entirely by poetic means—conceptual imagery and form; symbolic characters, actions, questions, contrasts, and contradictions; interplay of sight and sound; and pictorial representations of social realities. The work conveys both the abhorrence of war underestimated by those who, in the classical argument about Billy Budd, interpret it as Melville's “testament of acceptance” and the nonironic, even luminous, affirmation of man's latent humanity overlooked by those who read the book as irony, rejection, or darkness alone. In the course of his last artistic exploration Melville discovered that within the most cruel contradictions of the world of war lies the potential for its metamorphosis.
