Eric Adler demonstrates that current defenses of the humanities rely on the humanistic disciplines as inculcators of certain poorly defined skills such as "critical thinking." It criticizes this conventional approach, contending that humanists cannot hope to save their disciplines without arguing in favor of particular humanities content. As the uninspired defenses of the classical humanities in the late nineteenth century prove, instrumental apologetics are bound to fail. All the same, the book shows that proponents of the Great Books favor a curriculum that is too intellectually narrow for the twenty-first century. The Battle of the Classics thus lays out a substance-based approach to undergraduate education that will revive the humanities, even as it steers clear of overreliance on the Western canon. The book envisions a global humanities based on the examination of masterworks from manifold cultures as the heart of an intellectually and morally sound education.
