In a series of topical explorations structured like a sonata, H. L. Hix identifies the consequences of postmodern theory through such issues as grief, freedom, beauty, obscenity, love, and sex to its axiological consequences. A basic motif, postmodernism's distribution of meaning over space rather than time, recurs throughout the chapters, each of which in some way amplifies the book's underlying theme, virtue. The "exposition" of the theme in the first ten chapters receives its "development" in the chapter, "Postmodern Virtue," and its "recapitulation" in the aphorisms of the final chapter.

By choosing names like "deconstruction," postmodern theory postures as that which shakes foundations. But any declaration of an end is also a declaration of a beginning, and Spirits Hovering Over the Ashes pushes past the posturing to ask what foundations postmodern theory has laid.
