Kierkegaard's concept of despair

"The literature on Kierkegaard is often content to paraphrase. By contrast, Michael Theunissen articulates one of Kierkegaard's central ideas, his theory of despair, in a detailed and comprehensible manner and confronts it with alternatives. Understanding what Kierkegaard wrote on despair is vital not only because it illuminates his thought as a whole, but because his account of despair in The Sickness unto Death is the cornerstone of existentialism. Theunissen's book, published in German in 1993, is widely regarded as the best treatment of the subject in any language. Kierkegaard's Concept of Despair is also one of the few works on Kierkegaard that bridge the gap between the Continental and analytic traditions in philosophy."--Jacket.
