I was twenty-four, and the religious revival within myself was at its height. Earlier that summer, I had discovered Kierkegaard, and each week I brought back to the apartment one more of the Princeton University Press’s elegant and expensive editions of his works. They were beautiful books, sometimes very thick, sometimes very thin, always typographically exhilarating, with their welter of title pages, subheads, epigraphs, emphatic italics, italicized catchwords taken from German philosophy and too subtle for translation, translator’s prefaces and footnotes, and Kierkegaard’s own endless footnotes, blanketing pages at a time as, crippled, agonized by distinctions, he scribbled on and on, heaping irony on irony, curse on curse, gnashing, sneering, praising Jehovah in the privacy of his empty home in Copenhagen. The demons with which he wrestled—Hegel and his avatars—were unknown to me, so Kierkegaard at his desk seemed to me to be writhing in the clutches of phantoms, slapping at silent mosquitoes, twisting furiously to confront presences that were not there.
