Presented here in a new translation, with a historical introduction by the translators, Fear and Trembling and Repetition are the most poetic and personal of Soren Kierkegaard's pseudonymous writings. Published in 1843 and written under the names Johannes de Silentio and Constantine Constantius, respectively, the books demonstrate Kierkegaard's transmutation of the personal into the lyrically religious. Each work uses as a point of departure Kierkegaard's breaking of his engagement to Regine Olsen - his sacrifice of "that single individual." From this beginning Fear and Trembling becomes an exploration of the faith that transcends the ethical, as in Abraham's willingness to sacrifice his son Isaac at God's command. This faith, which persists in the face of the absurd, is rewarded finally by the return of all that the faithful one is willing to sacrifice. Repetition discusses the most profound implications of unity of personhood and of identity within change, beginning with the ironic story of a young poet who cannot fulfill the ethical claims of his engagement because of the possible consequences of his marriage. The poet finally despairs of repetition (renewal) in the ethical sphere, as does his advisor and friend Constantius in the aesthetic sphere. The book ends with Constantius' intimation of a third kind of repetition - in the religious sphere.

Soren Kierkegaard, the nineteenth-century Danish philosopher rediscovered in the twentieth century, is a major influence in contemporary philosophy, religion, and literature. He regarded Either/Or as the beginning of his authorship, although he had published two earlier works on Hans Christian Andersen and irony. The pseudonymous volumes of Either/Or 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. 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 Stages on Life's Way. The poetic-reflective creations of a master stylist and imaginative impersonator, the two men write in distinctive ways appropriate to their respective positions.

本书分为两部。上部共八篇，托名“Ａ的论文”。下部共三篇，托名“Ｂ的论文”。全书各篇看似各自独立，分别讨论不同的问题，却是一个具有内在联系的整体。《或此或彼》意在表明：存在的本质即是选择——要么这样，要么那样；不同选择之间不存在一个比另一个更优越。上部中“Ａ”的八篇作品主要讨论审美的人生态度，构成了“此”。下部“Ｂ”的三篇作品主要讨论道德的人生态度，提出了人生选择的问题，并涉及了宗教的人生态度，构成了“彼”。

《原野里的百合和天空下的飞鸟》是克尔凯郭尔关于宗教人生的陶冶性讲演，他由此成为一个拒绝教学的本真基督徒，他反复提取耶稣登山宝训中的段落——关于原野里的百合不劳作、不织衣和天空中的飞鸟不收获、不积聚，并以其诫喻性作为终结语；《一个女演员的生活中的危机》是典型的克尔凯郭尔式的审美散文，他说的是青春的、偶然的、无常的东西和成熟的、永恒的、本质的东西。

A companion piece to The Concept of Anxiety, this work continues Soren Kierkegaard's radical and comprehensive analysis of human nature in a spectrum of possibilities of existence. Present here is a remarkable combination of the insight of the poet and the contemplation of the philosopher. In The Sickness unto Death, Kierkegaard moves beyond anxiety on the mental-emotional level to the spiritual level, where - in contact with the eternal - anxiety becomes despair. Both anxiety and despair reflect the misrelation that arises in the self when the elements of the synthesis - the infinite and the finite - do not come into proper relation to each other. Despair is a deeper expression for anxiety and is a mark of the eternal, which is intended to penetrate temporal existence.
