In Continuity collects more than twenty years of distinguished essays by Austin Warren and completes his trilogy that began with Rage for Order (1948) and Connections (1970). These last essays of Warren include discussions of the writings and philosophies of Allen Tate, Lewis Carroll, William Law, T. S. Eliot, W. H. Auden, Robert Herrick, Walter Pater, and Robert Frost, as well as an autobiographical essay on Warren's own religious influences.

Through his essay collections and other literary studies, Warren helped shape generations of scholars; the approach represented here might best be called New England Common Sense New Criticism. With art and grace, this self-termed literary "generalist" reminds us through his lively prose of the continuity of great Western literature through the centuries, focusing in these essays on nineteenth- and twentieth-century authors.
