I was nervous and uncertain about the idea of an introduction to Kierkegaard. Kierkegaard tends to be a love-him-or-hate-him sort of writer, and much of the early English-language literature on him tends towards hagiography. Counter to this trend is the psychoanalytic streak many authors have, seeking to diagnose him as a particularly morbid personality.
Caputo's reputation made me want to try, as I wanted to see if there was an introduction out there appropriate for new readers of Kierkegaard. Caputo's book works, and largely due to his very sharp selection of texts. The book is arranged as brief commentaries on short, important texts which can emphasize different aspects of Kierkegaard's work.
Such excerpting is somewhat dangerous with an author as prolific and non-systematic as the subject, however, Caputo is largely fair in my estimation. He is particularly interested in Kierkegaard's view of subjectivity, but does not seem to imply the fideism he is accused of by other commentators. Caputo is obviously not fond of the later Kierkegaard, which he shares with us in places outside of the appropriate excerpt. It is true that the final years of Kierkegaard's work are hard to enjoy, but some greater detachment may have served the book's purpose better.
The book has many clear strengths as an introduction, however, including its brevity. An "introduction" to Kierkegaard would either be a multi-volume work, or just as short as this one is, and Caputo (and the editors of this series), wisely chose the latter. It doesn't get very deep into the literary quality of Kierkegaard, but Caputo does manage to highlight Kierkegaard as a prophet of modernity, which is perhaps his most generally appealing aspect.
For readers who have picked up one of Kierkegaard's works and found them overwhelming, or do not know where to start, this text is a good one. Add to it that there is no real competitor (at least in English), and it is a worthy volume indeed.
