This volume contains a new translation, with a historical introduction by the translators, of two works written under the pseudonym Johannes Climacus. Through Climacus, Kierkegaard contrasts the paradoxes of Christianity with Greek and modern philosophical thinking. In Philosophical Fragments he begins with Greek Platonic philosophy, exploring the implications of venturing beyond the Socratic understanding of truth acquired through recollection to the Christian experience of acquiring truth through grace. Published in 1844 and not originally planned to appear under the pseudonym Climacus, the book varies in tone and substance from the other works so attributed, but it is dialectically related to them, as well as to the other pseudonymous writings. The central issue of Johannes Climacus is doubt. Probably written between November 1842 and April 1843 but unfinished and published only posthumously, this book was described by Kierkegaard as an attack on modern speculative philosophy by "means of the melancholy irony, which did not consist in any single utterance on the part of Johannes Climacus but in his whole life. . . . Johannes does what we are told to do--he actually doubts everything--he suffers through all the pain of doing that, becomes cunning, almost acquires a bad conscience. When he has gone as far in that direction as he can go and wants to come back, he cannot do so. . . . Now he despairs, his life is wasted, his youth is spent in these deliberations. Life does not acquire any meaning for him, and all this is the fault of philosophy." A note by Kierkegaard suggests how he might have finished the work: "Doubt is conquered not by the system but by faith, just as it is faith that has brought doubt into the world!."

The first new translation of Kierkegaard's masterwork in a generation brings to vivid life this essential work of modern philosophy. Brilliantly synthesizing human insights with Christian dogma, Soren Kierkegaard presented, in 1844, The Concept of Anxiety as a landmark "psychological deliberation," suggesting that our only hope in overcoming anxiety was not through "powder and pills" but by embracing it with open arms. While Kierkegaard's Danish prose is surprisingly rich, previous translations—the most recent in 1980—have marginalized the work with alternately florid or slavishly wooden language. With a vibrancy never seen before in English, Alastair Hannay, the world's foremost Kierkegaard scholar, has finally re-created its natural rhythm, eager that this overlooked classic will be revivified as the seminal work of existentialism and moral psychology that it is. From The Concept of Anxiety: "And no Grand Inquisitor has such frightful torments in readiness as has anxiety, and no secret agent knows as cunningly how to attack the suspect in his weakest moment, or to make so seductive the trap in which he will be snared; and no discerning judge understands how to examine, yes, exanimate the accused as does anxiety, which never lets him go, not in diversion, not in noise, not at work, not by day, not by night."

The final volume of Princeton's Kierkegaard's Writings series, the Cumulative Index provides wide-ranging navigation to the preceding twenty-five volumes. Composed of over 90,000 entries, the Cumulative Index offers access to Kierkegaard's complex authorship and the extraordinary range of subjects he addressed in his writing. Covering the series' historical introductions, primary works, supplementary material (journal entries), and footnotes, the Cumulative Index provides a comprehensive entryway to more than 11,000 pages of text. Readers are able to survey via extended entries Kierkegaard's dual authorship, pseudonymous and signed; his numerous biblical allusions; his references to Christianity, God, and love; and his frequent use of analogies. A cumulative collation of the extensive supplementary material is also included, giving researchers and avid readers the opportunity to cross-reference Kierkegaard's Writings with his journals and papers published elsewhere in both English and Danish.

In Philosophical Fragments the pseudonymous author Johannes Climacus explored the question: What is required in order to go beyond Socratic recollection of eternal ideas already possessed by the learner? Written as an afterword to this work, Concluding Unscientific Postscript is on one level a philosophical jest, yet on another it is Climacus's characterization of the subjective thinker's relation to the truth of Christianity. At once ironic, humorous, and polemical, this work takes on the "unscientific" form of a mimical-pathetical-dialectical compilation of ideas. Whereas the movement in the earlier pseudonymous writings is away from the aesthetic, the movement in Postscript is away from speculative thought. Kierkegaard intended Postscript to be his concluding work as an author. The subsequent "second authorship" after The Corsair Affair made Postscript the turning point in the entire authorship. Part One of the text volume examines the truth of Christianity as an objective issue, Part Two the subjective issue of what is involved for the individual in becoming a Christian, and the volume ends with an addendum in which Kierkegaard acknowledges and explains his relation to the pseudonymous authors and their writings. The second volume contains the scholarly apparatus, including a key to references and selected entries from Kierkegaard's journals and papers.
