<p>Søren Kierkegaard, the nineteenth-century Danish philosopher rediscovered in the twentieth century, is a major influence in contemporary philosophy, religion, and literature. He regarded <i>Either/Or</i> as the beginning of his authorship, although he had published two earlier works on Hans Christian Andersen and irony. The pseudonymous volumes of <i>Either/Or</i> are the writings of a young man (I) and of Judge William (II). The ironical young man's papers include a collection of sardonic aphorisms; essays on Mozart, modern drama, and boredom; and "The Seducer's Diary." The seeming miscellany is a reflective presentation of aspects of the "either," the esthetic view of life.</p> <p>Part II is an older friend's "or," the ethical life of integrated, authentic personhood, elaborated in discussions of personal becoming and of marriage. The resolution of the "either/or" is left to the reader, for there is no Part III until the appearance of <i>Stages on Life's Way</i>. The poetic-reflective creations of a master stylist and imaginative impersonator, the two men write in distinctive ways appropriate to their respective positions.</p>
