In Kierkegaard's view, faith is the most essential task of life. Faith is not a matter of dogmatic adherence, but rather of subjective passion. In Purity of Heart, Kierkegaard discusses multiple facets of human existence, particularly the responsibility of each person to single-mindedly seek out spiritual understanding and ethical integrity. While insisting that each reader must find their own path, Kierkegaard does offer clues to the nature of goodness. Søren Kierkegaard (1813-1855) was a Danish philosopher and theologian. Much of his work deals with religious problems such as faith in God, the institution of the Christian Church, Christian ethics and theology, and the emotions and feelings of individuals when faced with life choices. "About the greatness of the book there can be no question. It should be regarded as the equivalent of shock therapy."-The Living Church
