Book excerpt: This volume, which follows hard on the heels of publication of the final volume of the 26-volume set of Kierkegaard's writings (Princeton, 1980-2000), allows its readers 'to find their way quickly to relevant sources of help,' elucidates Kierkegaard's 'central concepts,' and demonstrates the contemporary relevance of his ideas (he is 'important because of his emphasis on human subjectivity').
