For over a century, the Danish thinker Søren Kierkegaard (1813–55) has been at the center of a number of important discussions, concerning not only philosophy and theology, but also, more recently, fields such as social thought, psychology, and contemporary aesthetics, especially literary theory. Despite his relatively short life, Kierkegaard was an extraordinarily prolific writer, as attested to by the 26-volume Princeton University Press edition of all of his published writings. But Kierkegaard left behind nearly as much unpublished writing, most of which consists of what are called his "journals and notebooks." Kierkegaard has long been recognized as one of history's great journal keepers, but only rather small portions of his journals and notebooks are what we usually understand by the term “diaries.” By far the greater part of Kierkegaard’s journals and notebooks consists of reflections on a myriad of subjects—philosophical, religious, political, personal. Studying his journals and notebooks takes us into his workshop, where we can see his entire universe of thought. We can witness the genesis of his published works, to be sure—but we can also see whole galaxies of concepts, new insights, and fragments, large and small, of partially (or almost entirely) completed but unpublished works. Kierkegaard’s Journals and Notebooks enables us to see the thinker in dialogue with his times and with himself. Kierkegaard wrote his journals in a two-column format, one for his initial entries and the second for the extensive marginal comments that he added later. This edition of the journals reproduces this format, includes several photographs of original manuscript pages, and contains extensive scholarly commentary on the various entries and on the history of the manuscripts being reproduced. Volume 9 of this 11-volume series includes five of Kierkegaard’s important “NB” journals (Journals NB26 through NB30), which span from June 1852 to August 1854. This period was marked by Kierkegaard’s increasing preoccupation with what he saw as an unbridgeable gulf in Christianity—between the absolute ideal of the religion of the New Testament and the official, state-sanctioned culture of “Christendom,” which, embodied by the Danish People’s Church, Kierkegaard rejected with increasing vehemence. Crucially, Kierkegaard’s nemesis, Bishop Jakob Peter Mynster, died during this period and, in the months following, Kierkegaard can be seen moving inexorably toward the famous “attack on Christendom” with which he ended his life.

In his praise for Part I of Upbuilding Discourses in Various Spirits, the eminent Kierkegaard scholar Eduard Geismar said, "I am of the opinion that nothing of what he has written is to such a degree before the face of God. Anyone who really wants to understand Kierkegaard does well to begin with it." These discourses, composed after Kierkegaard had initially intended to end his public writing career, constitute the first work of his "second authorship." Characterized by Kierkegaard as ethical-ironic, Part One, "Purity of Heart Is to Will One Thing," offers a penetrating discussion of double-mindedness and ethical integrity. Part Two, "What We Learn from the Lilies in the Field and from the Birds of the Air," humorously exposes an inverted qualitative difference between the learner and the teacher. In Part Three, "The Gospel of Sufferings, Christian Discourses," the philosopher explores how joy can come out of suffering.

Kierkegaard’s Concepts is a comprehensive, multi-volume survey of the key concepts and categories that inform Kierkegaard’s writings. Each article is a substantial, original piece of scholarship, which discusses the etymology and lexical meaning of the relevant Danish term, traces the development of the concept over the course of the authorship, and explains how it functions in the wider context of Kierkegaard’s thought. Concepts have been selected on the basis of their importance for Kierkegaard’s contributions to philosophy, theology, the social sciences, literature and aesthetics, thereby making this volume an ideal reference work for students and scholars in a wide range of disciplines.

Early Polemical Writings covers the young Kierkegaard's works from 1834 through 1838. His authorship begins, as it was destined to end, with polemic. Kierkegaard's first published article touches on the theme of women's emancipation, and the other articles from his student years deal with freedom of the press. Modern readers can see the seeds of Kierkegaard's future career these early pieces. In "From the Papers of One Still Living," his review of Hans Christian Andersen's novel Only a Fiddler, Kierkegaard rejects the notion that environment is decisive in determining the fate of genius. He also puts forward his belief that each person needs a life-view or life for which and by which to live, a thought he explores further in the comic play The Battle between the Old and the New Soap-Cellars.
