I recently read a piece entitled "Zen for the West" by American philosopher and essayist William Barrett (1913 - 1992). In his essay, Barrett refers to Danish philsopher and theologian Soren Kierkegaard, and Kierkegaard's references to the Knight of Faith and the Knight of Resignation. While my research is quite incomplete, I include this post to encourage others in search of truth to explore his writings, particularly his work Fear and Trembling. I steal these excerpts directly from Wikipedia to spark your interest.
