Jacques Maritain wrote in 1964, “Soren Kierkegaard was a contemporary of Marx. But it was only at the beginning of the twentieth century that his name began to become famous and his influence to be felt. Neither a philosopher in the strict sense of the word-although nourished in philosophy-and yet a philosopher in the sense of being a lay thinker; nor a theologian nor a prophet (obsessed by his feeling for the requirements of the Gospel and by his own unworthiness, he hardly dared to profess himself a Christian), and yet a kind of prophet and a knight of faith, and, at the end of his life, “a witness to the truth” in his passionate revolt against the established church, this poet of the religious, as he called himself, is a figure complex and ambiguous enough to occupy generations of interpreters and to justify their disagreements.” He also claimed that Theodor Haecker was a knight of faith.
