Fear and Trembling is the work that gave rise to the notion of a Kierkegaardian "leap of faith," one of my favorite philosophical concepts. I read portions of this book as an undergrad, but finally sat down to read it in full. For Kierkegaard, religious faith transcends the Hegelian premise of the ethical as universal and can only be understood by virtue of a leap into the absurd. He illustrates this to great poetic effect with various interpretations of the Biblical tale of Abraham and Isaac. Kierkegaard is always entertaining and this slim book is no exception. However, this is one of the least coherent works in his famously weird oeuvre and easily the least fun to read. YMMV, but a summary of this book might be better than slogging through it.
