What exactly is the fantastic? In the twentieth-century world, our notions of what is impossible are assaulted every day. To define the nature of fantasy and the fantastic, Eric S. Rabkin considers its role in fairy tales, science fiction, detective stories, and religious allegory, as well as in traditional literature. The examples he studies range from Grimm's fairy tales to Agatha Christie, from Childhood's End to the novels of Henry James, from Voltaire to Robbe-Grillet to A Canticle for Leiboivitz. By analyzing different works of literature, the author shows that the fantastic depends on a reversal of the ground rules of a narrative world. This reversal signals most commonly a psychological escape, often from boredom, to an unknown world secretly yearned for, whose order, although reversed, bears a precise relation to reality.

The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
